Upregulation of Egr proteins during positive selection is dependent upon the Ras/MAPK pathway 13. Egr proteins are direct transcriptional targets of ternary complex factor Sap-1, which is itself a substrate of Erk and essential for positive selection 23. In addition, Egr2 and Egr3 are regulated by calcineurin signaling, likely via NFAT 13, 20, 22. Both Egr1 and Egr3 have roles in positive selection. Egr1 overexpression

enhances positive selection of cells with low affinity TCR 24. Conversely, Egr1-deficient mice have impaired positive selection 25; although the initial TCR signal is transduced, Small molecule library concentration cells stall at the DP to SP transition, resulting in a numerical decrease in CD4 and CD8 SP. Animals doubly deficient for both Egr1 and Egr3 have a similar but more marked selection phenotype, and CD8 differentiation is significantly Imatinib cost impaired 14. For both Egr1 and Egr3, the principal reason for the alterations in SP cell number is a change in the cells’ susceptibility to apoptosis, at least partly through regulation of pro- and anti-apoptotic Bcl2 family members 14, 25. Egr2 is similarly important in DP thymocytes. Recently, analysis of mice in which Egr2 was deleted in DN thymocytes has shown that it is not required for negative selection, but

that positive selection of both CD4 and CD8 lineages is impaired in the absence of Egr2. This defect is at least partially due to increased apoptosis as it is rescued by overexpression of the survival factor Bcl-2 26; however, the mechanism by which Egr2 might be regulating survival has not been established. Here, we present a detailed investigation of the role of Egr2 in positive selection using stage-specific inducible-transgenic and inducible-knockout mice. We show that gain- or loss-of-function of Egr2 has reciprocal effects

on the numbers of SP thymocytes generated, with more SP cells when Egr2 is overexpressed, and fewer when Egr2 is absent, and that this is due to an effect downstream of the positive selection signal from the TCR, associated with changes in the survival and Bcl-2 expression of DP cells. We go on to show that downregulation Molecular motor of Egr2 results in inhibition of the IL-7-mediated survival pathway in post-selection thymocytes. These data extend and complement existing knowledge, and fit well with studies on Egr1 and Egr3, suggesting that all three Egr family members play important and distinct roles as transcriptional transducers of the TCR signal following positive selection. Egr2 has previously been shown to be induced in naïve DP cells upon ligation of the TCR 15. To investigate Egr2 expression during selection in more detail, we sorted thymocytes from WT mice into subsets, based on their expression of CD4 and CD8, TCR-β, and the activation marker CD69. Sort gates are shown in Fig. 1A.

Acinetobacter baumannii strains 98-37-02, 98-37-05, and 98-37-09 were originally isolated from sputum, tracheal aspirate, and cerebrospinal fluid, respectively, of infected patients during a 1998 Texas outbreak, whereas strain 07-09-54 was isolated during a 2007 Kentucky outbreak

and was obtained from the Centers for Disease Control and Prevention (CDC). ATCC 17978, 07-09-54, and 98-37-05 are described as serum-susceptible or serum-intermediate strains while 98-37-02, 98-37-05, and 98-37-09 are serum-resistant strains that are able to readily proliferate in 100% human serum (Jacobs et al., 2010). All strains were selleck chemical grown in Luria–Bertani (LB) medium (Becton Dickinson, Franklin Lakes, NJ) or cultured in 100% normal human serum (MP Biomedicals, Solon, OH). Overnight cultures of A. baumannii ATCC 17978 or 98-37-09 were used to inoculate (1 : 100 dilution) 50 mL of fresh LB medium or 100% serum at a volume-to-flask ratio of 1 : 5. Cultures were incubated at 37 °C and 225 r.p.m. to exponential phase (OD600 = 0.4) or stationary phase (OD600 = 2.2). Cultures grown in LB medium were then mixed with an equal volume of ice-cold ethanol : acetone (1 : 1) and stored at −80 °C until RNA isolation. Acinetobacter baumannii 98-37-09 cultured in 100% human serum was collected by centrifugation (2000 g

at 4 °C for 10 min), washed twice with TE buffer (10 mM Tris–HCl, 1 mM EDTA, pH 7.6), resuspended in ice-cold ethanol-acetone (1 : 1), and stored at −80 °C until RNA isolation. Torin 1 mw For RNA isolation, samples were thawed on ice, and cells were collected by centrifugation at 2000 g at 4 °C for 10 min. Cell pellets were washed once in TE buffer and then suspended in 500 μL TE buffer, transferred to lysing matrix B tubes (MP Biomedicals), and lysed by two cycles of mechanical disruption in a FP120 shaker (Thermo Scientific, Waltham, MA) at settings 5.0 and 4.5 m s−1 for 20 s. Cell debris was removed by centrifugation

at 16 000 g at 4 °C for 10 min, and the supernatants were used for RNA isolation using Qiagen RNeasy® Mini columns, else following the manufacturer’s recommendations for prokaryotic RNA purification (Qiagen, Valencia, CA). RNA concentrations were determined by spectrophotometry (OD260 1 = 40 μg mL−1). Ten micrograms of each RNA sample was reverse transcribed, fragmented, 3′ biotinylated, and hybridized to an A. baumannii GeneChip®, following the manufacturer’s recommendations for antisense prokaryotic arrays (Affymetrix, Santa Clara, CA). The GeneChips® used in this study, PMDACBA1, are custom-made microarrays that were developed based on the genomic sequence of A. baumannii strain ATCC 17978 and all additional unique A. baumannii GenBank entries that were available at the time of design (Smith et al., 2007). In total, 3,731 predicted A.

In recent years, good experimental data has been provided to show that host regulatory pathways are activated by certain GI parasites in particular helminths. For example, the duodenal-dwelling nematode Heligmosomoides polygyrus can inhibit gut inflammation in the mouse associated with Helicobacter colitis [48], genetic IL-10 deficiency [49] or peanut allergy [50]; the same parasite stimulates Treg expansion and induction in vivo and in vitro[51–53]. In Trichuris muris infections of the colon, Tregs are required to minimize intestinal pathology and the parasite strain able to survive longest in the mouse is associated with the largest numerical expansion in Tregs[54]. Although

data from

human helminth infections are not so definitive, new and remarkable evidence has been provided for the presence of GI helminth-associated Tregs. A cohort of multiple sclerosis patients were Y-27632 ic50 found to have acquired selleck kinase inhibitor gut helminth infections while under longitudinal monitoring in the clinic; infected individuals showed a dramatically lower rate of relapse, with milder clinical scores, than case–controlled uninfected patients. Infected subjects showed higher correlates of Treg activity and lower inflammatory cytokine production on autoantigen stimulation, linking the helminth infection with expanded Treg activity and improved clinical outcome [55]. Studies to date have not been defined whether the Treg subsets stimulated by GI helminths are natural or induced, or if there are parasite-specific Treg populations among them. In addition, the relative importance of Tr1 (non-FoxP3-expressing, IL-10-producing) regulatory cells is brought into question by the dispensible nature of IL-10 for many

helminth-associated regulatory effects (for example [56]). By contrast, new data are clearly demonstrating an inherent capacity to promote induced Treg development and function in the stiripentol case of H. polygyrus secretions which drive de novo expression of FoxP3 in naive peripheral T cells. The distinction between Tregs and inducible regulatory T cells in vivo is not always clear, particularly in highly inflammatory settings. Moreover, Tregs may be able to influence the emergence or function of one another. This notion was suggested recently in a model of Aspergillus conidia infection in mice. In this model, control of allergic immunopathology induced by the fungus required the sequential activity of various populations of Tregs[57]. This sequential role for various populations of Tregs may not be an exception but rather the rule, as most infections proceed through various stages and therefore require various layers of regulation. The host, on the other hand, has many mechanisms which may uphold or restore responsiveness in a counter-regulatory fashion.

9% for Group A, 34.1 ± 4.2% for Group B, and 51.3 ± 3.3% for Group C at 12 weeks. There was no statistical difference between Groups A and C, but Group A was statistically greater when compared to B, and when Group C was PLX-4720 ic50 compared to B. In conclusion, acellular nerve allograft demonstrated equal functional recovery when compared to reversed autograft (control), and superior recovery compared to the cabled nerve autograft. © 2013 Wiley Periodicals, Inc.

January 2000 to May 2008, 50 patients with facial contour deformities underwent soft tissue augmentation with 51 anterolateral thigh (ALT) adipofascial flaps. Fifty flaps survived with no complications; partial fat necrosis occurred in one flap. Mean follow-up was 16 months. Flaps ranged from 10 × 6 cm to 20 × 12 cm. Perforators were found in 50 flaps, 43 musculocutaneous perforators (84.3%) and 7 septocutaneous perforators (13.7%), with a mean of 2.5 perforators per flap. In one flap (2.0%), no perforator was found. In this case, we used an anteromedial thigh adipofascial flap using the medial

branch of the descending branch of lateral circumflex femoral artery as the vascular pedicle. Relatively symmetric facial contour was achieved in 20 cases. In 30 cases, adjunctive procedures including flap debulking, fat injection, and resuspension were necessary, and 23 patients achieved satisfactory outcomes. We conclude that the ALT adipofascial flap can be successfully elevated and transplanted for the correction of soft tissue facial defects. This flap can provide tissue to Oxaprozin fill large defects, and posses selleck chemicals the qualities of pliability, an excellent blood supply, ease of suspension and fixation, and minimal morbidity at the donor site. © 2010 Wiley-Liss, Inc.

“The purpose of this study was to examine the current role of the iliac crest osteocutaneous flap in mandibular reconstruction, with a focus on the reliability of its skin island. We reviewed outcomes in 18 cases of immediate mandibular reconstruction with the iliac crest flap. Intraoral mucosal defects were closed with the skin island of the iliac crest flap in 13 patients (iliac crest flap group) and were closed with another free flap, because of poor circulation of the iliac crest skin island, in five patients (double-flap group). Postoperative results were poor in the iliac crest flap group. The rate of partial or total loss of the skin island was 46.2% in the iliac crest flap group and 20.0% in the double-flap group. The presence of a dominant perforator did not reduce the overall rate of recipient-site complications or reoperation. Combined use of another skin flap for intraoral lining provided better results. These results suggest that the skin island of the iliac crest flap should not be used for intraoral lining, unless adequate circulation of the skin island can be confirmed.

Sample volumes were adjusted to patients’ body weight with a maximum for all samples combined of 10% of circulating volume. Because only limited amount of blood volume was often obtainable from the young patients, not all assays could be performed on all 25 patients. Mononuclear cells were isolated from heparinized blood samples (T1, T4 and T5) using the Ficoll Isopaque density gradient centrifugation (Amersham Pharmacia selleck chemicals Biotech, Uppsala, Sweden). Peripheral blood mononuclear cells were washed in FACS buffer (PBS containing 2% FCS and 0.1% sodium azide),

adjusted to 4.0×106 cells/mL in FACS buffer and blocked with normal mouse serum. The cells were incubated in 50 μL FACS buffer containing the appropriately diluted Fitc, PE, PercP or APC-labeled antibodies against human CD3, CD4, CD25, CD69, CD127, or GITR. For cytoplasmatic staining of cytotoxic T lymphocyte antigen 4 (CTLA-4) and Ki-67, the cells were first

surface stained, then fixed in Cytofix/Cytoperm (20 min, 4°C) and washed twice in Perm/Wash solution (Cytofix/perm kit, BD Biosciences, San Jose, CA, USA), followed by incubation with the appropriate antibody. Intranuclear staining of FOXP3 was performed after fixation and permeabilization according to the manufacturer’s protocol and subsequently incubated with the appropriate antibody. Antibodies against CD4 (clone SK3), CD25 (2A3), CD69 (L78), CD127 (hIL-7R-M21) and CTLA-4 (BN13) were obtained Dabrafenib solubility dmso from BD Bioscience, GITR (110416) from R&D (Minneapolis, MN, USA) and Ki67 (MIB-1) from Immunotech (Marseilles, France), FOXP3 (PCH101) from eBioscience (San Diego, CA, USA). Finally,

stained mononuclear cells were washed twice in FACS buffer and run on a FACS Calibur (BD Biosciences). CellQuestPro software (BD Biosciences) was used for analyses. The gates for the different populations were set for the sample prior to surgery and kept identical for the following samples (Supporting Information Fig. 1A). From plasma obtained at five time points (immediately before and after surgery, and 4, 24 and 48 h after surgery), IL-6 and IL-8 levels were determined by multiplex why immunoassay as previously described 47, 48. According to the intensity of CD25 expression, CD4+CD25bright, CD4+CD25intermediate and CD4+CD25 T cells were isolated from samples before surgery and 24 h after surgery. The gates for these three populations were kept identical at both time points. Isolation of total RNA and quantification of FOXP3 mRNA were performed as previously described 11. Forty million isolated peripheral blood mononuclear cells were stained for CD4 and CD25 as described above. Cells were fixated and stained for FOXP3 Alexa-488 (PCH101) according to manufacturer’s instructions (eBioscience). The cell sample was sorted by FACS in the three appropriate populations according to the intensity of CD25 expression.

Levels of KLF4 can be manipulated by diverse agonists such as statins, resveratrol, bortezomib and dietary compounds, so these factors could be influential for TAM re-education.[130] Although still DAPT datasheet preliminary, the association among c-Myc, STAT6 and M2 polarization has been proposed by recent studies. As reported, c-Myc up-regulated IL-4-mediated STAT6 activation and elevated the expression of 45% of the genes correlated with alternative activation of macrophages.[131] In contrast, c-Myc inhibition blocked the expression of some pro-tumoral genes.[131] Other proteins and signalling pathways known

to promote M2-like properties of macrophages are also the potential targets for tumour therapy. They include peroxisome Erlotinib supplier proliferator-activated receptor (PPARs), HIFs, Ets family member 2 (Ets2), Decoy receptor

(DcR3) and mammalian target of rapamycin (mTOR). First, PPAR-γ can promote M2 type differentiation of human macrophages by acting as a transcriptional inhibitor of NF-κB.[132] PPAR-α plays a role in macrophages by antagonizing M1 polarization and supporting M2 polarization.[133] As synthetic inhibitors of PPAR-α/γ have now been identified, the evaluation of their role in TAM-targeted therapy is essential. Second, HIFs are a hopeful target because of their over-expression in TAMs residing in the hypoxic tumour microenvironment and their ability to induce the production of angiogenic factors, including VEGF, platelet-derived growth factor-β, NOS2, fibroblast growth factor 2, IL-8 and cyclooxygenase-2.[134] In fact, macrophage-targeted depletion of HIF-1α reduced tumour

growth in mice.[135] Therefore, it would be interesting to see whether blocking HIFs could slow or halt tumour recovery. Third, Ets2 is a direct effector of the M-CSF signalling pathway, and so facilitates the formation of M2 macrophage. Zabuawala et al.[136] demonstrated that an Ets2-driven transcriptional program in TAMs could promote enough the angiogenesis and metastasis of murine breast cancer. Interestingly, an Ets2-TAM gene signature consisting of 133 genes retrospectively predicted overall survival of breast cancer patients.[136] Investigations of DcR3 and mTOR are also interesting.[137, 138] Several anti-tumour drugs that are able to suppress M2 macrophages will be introduced as follows. (i) Histidine-rich glycoprotein (HRG): HRG can skew TAMs to M1 type by down-regulation of PIGF, a member of the VEGF family, and can combat tumour malignancy by enhancing immunity and vessel normalization.[26] Macrophages are a direct target of HRG; and re-education of TAMs is essential for HRG-mediated anticancer effects.[26, 139] (ii) Copper chelate (CuNG): A novel CuNG was demonstrated to modulate the cytokine profile of TAMs isolated from chemotherapy-resistant or radiotherapy-resistant cancer patients.

The Golgi apparatus

was occasionally found, and its cisternae were usually swollen. Lipofuscin was also observed in the cytoplasm. Mitochondria were well-preserved (Fig. 7). In addition, autophagosomes were increased in number. They localized widely in perikaryon occasionally with grouping, and engulfed some pieces of cytoplasm Gamma-secretase inhibitor or membranous structures in large or small vacuoles. Membrane-bound globular dense bodies of 0.3–1.8 µm in diameter were found in the cerebrum. One or several of these structures were observed in both perikarya and dendrites of the neuron. In the cerebellum, Purkinje cells were atrophic with high electron density. Nuclei of Purkinje cells were shrunken with aggregation of chromatin, and the nuclear membrane was occasionally indistinct. Many autophagosomes which were seen in cerebral neurons were also found in the perikarya of Purkinje cells. The Golgi apparatus showed enlargement of the cisternae. Membrane-bound dense bodies were observed in the cytoplasm of Purkinje cells. Granule cells in the cerebellum were focally atrophic with high electron density. Others were clear with Neratinib an edematous perikaryon. A few free ribosomes were found in each of the atrophic granule cells, but they were rare in swollen granule cells. Parallel fibers were mixed

in the molecular layer. Parallel fibers were well-preserved, but their size was not uniform. The spines of Purkinje cells showed high electron density. These spines formed synaptic contacts to the big parallel fibers. The terminals of presynapses were enlarged and contained large mitochondria or synaptic vesicles (Fig. 8). A report from the Second Department of Pathology, Kumamoto University School of Medicine in 1959, indicated that organic mercury was the most probable cause of MD.18 One week later, Hosokawa et al. initiated an experiment in order to assess the toxicity of industrial wastewater from the acetaldehyde plant but the results were not published until 2001.12 Pathological changes caused by Me-Hg occur predominantly in selective areas of the cerebrum, including the calcarine region,

the post- and precentral gyri and the temporal transverse gyrus.19 old These are localized near the deep sulci, comprising the calcarine fissure, central sulci (Roland’s fissure) and Sylvian’s fissure (Figs 3,4). Ischemia may be a result of the compression of arteries by edema of the adjacent tissues. Studies of acute Me-Hg poisoning in marmosets revealed edema in the white matter of occipital lobes. In acute cases of Me-Hg poisoning, neuron loss with gliosis was found in all layers of the cortex. The second and third layers of cortices are damaged in moderate or mild cases of poisoning. As a result of the location of the pathological changes, there were bilateral concentric constriction of the visual fields and impairment of visual acuity.

“T cells express multiple integrin molecules. The significance of signaling through these molecules on acquisition of T-cell effector functions and memory formation capacity remains largely unknown. Moreover, the impact of stimulation through these signals on the generation of T cells for adoptive immunotherapy has not been elucidated. In this study, using a recombinant fragment of fibronectin, CH-296, we demonstrated that stimulation via very late Ag (VLA)-4 and VLA-5 in human and BALB/c mouse CD8+ T cells, in combination with TCR stimulation, enhances effector multifunctionality and in vivo memory formation. Using TCR-transgenic mouse-derived CD8+ T cells expressing TCR specific for the syngeneic CMS5 fibrosarcoma-derived tumor Ag, we showed that stimulation by CH-296 improved the ability of tumor-specific CD8+ T cells to inhibit CMS5 tumor growth when adoptively transferred into hosts with progressing tumors. Improved antitumor GDC-0973 supplier effects were associated with decreased infiltration of Foxp3+CD4+

Treg cells in tumors. These results suggest that stimulation via VLA-4 and VLA-5 modulates the qualities of effector T cells and could potentially increase the efficacy of adoptive therapy against cancer. “
“CD4+ T cells with immune regulatory function can be either FOXP3+ or FOXP3−. We have previously shown that

priming of naturally occurring TCR-peptide-reactive CD4+FOXP3− Treg specifically controls Vβ8.2+CD4+ T cells mediating EAE. However, the mechanism by which these Treg are primed to recognize their cognate antigenic determinant, which is derived from the TCRVβ8.2-chain, is not known. In this study we show that APC derived from splenocytes of naïve mice are able to stimulate cloned CD4+ Treg in the absence of exogenous antigen, and their stimulation capacity is augmented during EAE. Among the APC populations, DC were the most efficient in stimulating the Treg. Stimulation of CD4+ Treg was dependent upon processing and presentation of TCR peptides from Amino acid ingested Vβ8.2TCR+CD4+ T cells. Additionally, DC pulsed with TCR peptide or apoptotic Vβ8.2+ T cells were able to prime Treg in vivo and mediate protection from disease in a CD8-dependent fashion. These data highlight a novel mechanism for the priming of CD4+ Treg by CD8α+ DC and suggest a pathway that can be exploited to prime antigen-specific regulation of T-cell-mediated inflammatory disease. Suppression of autoaggressive T-cell responses can be mediated by several subsets of lymphocytes; for example, CD4+CD25+FOXP3+, CD4+CD25+FOXP3−, CD8αα+TCRαβ+ and NKT subsets of T cells 1–5.

68–71 The HLA genetic map of Europe is also Ceritinib mouse characterized by an extreme differentiation of some populations, like the Norwegian Sami (high cumulated frequencies of A*03:01G, B*27:05G, C*01:02, DRB1*08:01 and DQB1*04:02), which are more closely related, genetically, to the Finnish population speaking a language of the same Uralic family (non Indo-European) than to other Norwegians.72 On the other hand,

Basques, a cultural and linguistic isolate in Northwest Spain, only exhibit slightly different HLA frequencies compared with Indo-European populations,73,74 which is consistent with genome-wide scale analyses.75 In East Asia, latitudinal genetic clines are observed at all classical HLA loci, with higher levels of internal genetic diversity in Northeastern than in Southeastern populations.19 Uneven distributions of some HLA alleles and allelic lineages are also found between Northeast and Southeast Asian populations, with a restricted geographic distribution of some alleles detected in the south (HLA-A*02:03, *02:07, *11:02, B*13:01, *15:02, *38:02, *46:01, C*04:03, DPB1**21:01, DRB1*12:02, *13:12, *14:04), whereas many alleles observed in the north Sunitinib manufacturer are more globally distributed.19 These results challenge current views sustaining

a unique origin of East Asian populations in Southeast Asia (e.g. ref. 76), as they are more compatible with an overlapping model (comparable to the ‘pincer model’ proposed by Ding et al.77) suggesting that modern humans arrived in East Asia from the west through both a northern and a southern route, and after that underwent substantial gene flow by migrating both northward from the south and southward from the north, but at different periods, in East Asia.19 Some results are also relevant for Oceania. For below example, HLA-DRB1 data confirm some genetic relationship between Papua New Guinea Highlands

populations and Australian Aborigines (with several DRB1*04 and DRB1*14 alleles shared among them), indicating that they may be common descendants of an ancient colonization of this area,78 which was a unique landmass (‘Sahul’) during Palaeolithic glacial periods. On the other hand, Australian and Papuan populations differ genetically from Austronesian-speaking populations, which are highly diversified among them, and more particularly Taiwan aborigines,79,80 whose geographic expansion colonized the entire Pacific area during the last 4500 years. As a relevant illustration, Fig. 3 shows a summarized view (average genetic distances on loci HLA-A, -B and -DRB1) of HLA genetic relationships in East Asia (including Taiwan aborigines).

g. ‘greater than the maximum value (>)’ or ‘smaller than the minimum value (<)’. However, there was categorical concordance in addition to essential agreement between X-396 concentration the results obtained with the MicroScan method and the reference method for ampicillin in 19/26 isolates (73.0%), for clindamycin in 16/26 isolates (61.5%), for gentamicin in 25/26 isolates (96.2%), for imipenem in 25/26 isolates (96.2%), for levofloxacin in 26/26 isolates (100%),

for linezolid in 26/26 isolates (100%), and for vancomycin in 26/26 isolates (100%) (Table 4). MICs for some isolates differed from the reference values when determined using the MicroScan method against ampicillin (7/26 isolates, 27.0%). MICs for clindamycin determined using the MicroScan method were higher (>2 log2 dilution) compared with those obtained with the reference

Nivolumab method for 10/26 isolates (38.5%). The Etest method showed essential agreement with the reference method for ampicillin in 16/20 isolates (80.0%), for clindamycin in 26/26 isolates (100%), for gentamicin in 26/26 isolates (100%), for imipenem in 23/23 isolates (100%), for levofloxacin in 22/22 isolates (100%), for linezolid in 26/26 isolates (100%), for meropenem in 18/23 isolates (78.3%), and for vancomycin in 23/26 isolates (88.5%) (Table 4). The Etest method showed a combination of categorical concordance and essential agreement for ampicillin in 19/26 isolates (73.0%), for clindamycin in 26/26 isolates (100%), for gentamicin in 26/26 isolates (100%), for imipenem in 26/26 isolates (100%), for levofloxacin in 26/26 isolates (100%), for linezolid in 26/26 isolates (100%), for meropenem in 21/26 isolates (80.8%), and for vancomycin in 23/26 Cediranib (AZD2171) isolates (88.5%) (Table 4). Three isolates showed higher Etest MICs for vancomycin compared with the reference results and five showed lower MICs for meropenem. Results obtained with the MicroScan and the Etest

methods agreed with the reference results for all of the antimicrobials examined in the case of the control strain (S. aureus ATCC29213). Medical records were reviewed retrospectively to investigate the past history, the current disease, its treatment, and the outcome. In addition, medications (including antimicrobials), the dietary history, catheterization, and other procedures performed before B. cereus was isolated were reviewed (Table 1). Malignancy as an underlying disease and use of central or peripheral venous catheters during the 3-month period before B. cereus was isolated were common in both groups. Our results also showed that the use of antimicrobials for more than 3 days during the 3-month period before isolation of B. cereus was significantly larger in the BSI group (P = 0.012). This report focuses on profiles of the virulence genes and antimicrobial susceptibility of 26 B.
