Abstracts accepted for publication only Pathogenesis R2249 Effect of a probiotic dairy product containing Lactobacillus casei Shirota on the gut microbiota in irritable bowel syndrome: a randomised, placebo-controlled, double-blind study Objectives: It has been hypothesized that disturbances in the intestinal flora could be a factor in the onset and persistence of IBS complaints. The aim of the study was to analyse the effect of Lactobacillus casei Shirota (LcS) on the faecal flora of IBS patients. Methods: In a randomised, placebo controlled, double blind study, IBS patients fulfilling the Rome criteria II were included. Patients took 2 bottles daily for 8 weeks, containing either LcS or placebo. Faecal samples were collected before intervention (week −2/0,S1), at the end of intervention (week 6/8,S2) and during follow-up (week 14/16,S3). Microbial populations (Bacteroides, anaerobes, bifidobacteria, coliforms, clostridia, and lactobacilli) were enumerated using quantitative plating. Total bacterial counts were performed using FISH. Bacterial DNA was analysed by quantitative Real-Time PCR for the detection of Atopobium spp., Bacteroides-Prevotella-Porphyromonas group, Clostridium coccoides-Eubacterium rectale group, Clostridium leptum subgroup, Clostridium difficile, Clostridium perfringens, Desulfovibrio desulfuricans group, and Bifidobacterium spp. Statistical analysis was performed using Mann-Whitney U tests or Paired Wilcoxon tests. P < 0.05 was considered statistically significant. Results: No significant differences in total bacterial counts were seen between the treatment and placebo group. Using quantitative plating, no significant differences were seen for the different bacterial groups between both groups. Significantly lower bacterial counts were seen in both groups for clostridia for S2 compared to S1 and S3. In the placebo group, significantly higher amounts of bifidobacteria and lactobacilli were detected for S2 compared to S1. Using qRT-PCR, significantly lower counts for D. desulfuricans group were seen in the placebo group compared to the treatment group. In the treatment group significant differences were seen only for S2 compared to S3, whereas in the placebo group, no significant differences were detected for the different bacterial groups at the different sampling points. Analysis at the IBS subtype level revealed differences in microbiota between the different subtypes. Conclusions: Although significant changes in the microbiota were seen during intake of LcS in the treatment group, differences in microbial populations between both groups were not significant. Interestingly, specific findings are likely to be associated with a specific IBS subtype rather than with IBS in general. Objective: To asses the chest radiography findings of patients with H1N1 Influenza virus infection. Review of radiological findings of 110 patients with confirmed influenza A virus infection admitted to two Hospitals in Cantabria, Spain. The radiological findings were characterized by pattern of opacities, lung distribution and, presence or absence of pleural effusions or hiliar or mediastinal adenopahies. The initial radiography was abnormal in 39 (34%) patients, but only 28 (25%) were related exclusively to the influenza A virus infection. Characteristic imaging findings in these 28 patients included: parenchymal consolidation 68%, consolidation plus ground glass 25% and ground glass opacities in 7%. Seventeen patients had a diffuse distribution of the opacities, in 61% it was bilateral, and lower and middle zones were those most frequently affected. No pleural effusions or pathological mediastinal lymph nodes were seen in this initial radiography. Patients with abnormal chest X-ray were more frequently men, smokers, had dyspnoea, pleuritic pain and diarrhoea. Conclusions: Although more of patients with influenza virus A infection showed normal chest X-ray, those with abnormal chest radiographies, characteristically showed areas of consolidation with or without ground glass affectation, bilateral and diffuse distribution, and predilection for lower and middle zones. Pleural effusion or mediastinal adenopahty were not findings seen in the initial radiography.

Q: Paragraph: BACKGROUND-HIV-1-infected mononuclear phagocytes release soluble factors that affect the homeostasis in tissue. HIV-1 can prompt metabolic encephalopathy with the addition of neuronal dysfunction and apoptosis. Recently, we reported that HIV-1 enhances the expression and secretion of bioactive cathepsin B in monocyte-derived macrophages, ultimately contributing to neuronal apoptosis. In this research, we request if microglia respond to HIV infection similarly by modifying the expression, secretion, neurotoxic potential of cathepsin B and the in vivo relevance of these findings. METHODS-HIV-ADA infected human primary microglia and CHME-5 were assessed for expression and activity of cathepsin B, its inhibitors, cystatins B and C, and neurotoxicity associated with these changes. Human primary neurons were exposed to supernatants from HIVinfected and uninfected microglia in the presence of cathepsin B inhibitors and apoptosis was assessed by TUNEL. Microglial expression of cathepsin B was validated in brain tissue from HIVE patients. microglia secreted significantly greater levels of cathepsin B, cystatin B, and cystatin C compared to uninfected cells. Increased apoptosis was observed in neurons exposed to supernatants from HIV-1 infected microglia at days 12 post-infection. The cathepsin B inhibitor CA-074 and cathepsin B antibody prevented neuronal apoptosis. Increased microgliaderived cathepsin B, cystatin B, and cystatin C and caspase-3+ neurons were detected in HIVE brains compared to controls. CONCLUSIONS-Our results suggest that HIV-1-induced cathepsin B production in microglia contributes to neuronal apoptosis and may be an important factor in neuronal death associated with HIVE. Human primary neuron and microglia isolation and culture-Human primary neurons and microglia were provided by Temple University's Comprehensive NeuroAIDS Center. Fetal brain tissue (gestational age 16-18 weeks) was obtained from elective abortion procedures performed in full compliance with National Institutes of Health and Temple University ethical guidelines. The tissue was washed with cold Hanks balanced salt solution (HBSS) and meninges and blood vessels were removed as previously described [Huang et al, 2011; Ghorpade et al, 1998].. For microglia, brain tissue was supplemented with Ca 2+ and Mg 2+ and then digested with 0.25% trypsin (Sigma) for 30 min at 37°C. Trypsin was neutralized with fetal bovine serum (FBS), and the tissue was further dissociated to obtain single-cell suspensions. The cells were cultured in DMEM (Sigma), supplemented with a mixture containing 10% heat-inactivated FBS, 1,000 U of purified recombinant human macrophage colony stimulating factor (MCSF) per ml, penicillin and streptomycin (50 mg/ ml), and 100 mg/ml of neomycin. The mixed culture was maintained under 5% CO 2 for 7 days, and the medium was fully replaced to remove any cell debris. The microglia cells released with further incubation were collected and purified by preferential adhesion. Microglia were seeded as an adherent monolayer at a density of 3 × 10 6 cells/well in a 6well plate and floating cells were removed after 4h. For neurons, tissue in HBSS was digested with papain (Sigma-Aldrich, St. Louis, MO) for 30 min at 37°C. Tissue was then dissociated to obtain single-cell suspensions by repeated pipetting with small bore fire polished glass Pasteur pipettes. Cells were plated in poly-D lysine-coated dishes at a density of ~ 1.8 × 10 6 cells/60mm dish in neurobasal media with B27 supplement, horse serum, and gentamicin (Invitrogen). After 2hr of attachment, media was replaced with fresh complete neurobasal media. Twenty-four hours later, cultures were replaced with neurobasal media without horse serum. Four days later, one fourth of the media was removed and replaced with neurobasal media supplemented with fluorodeoxyuridine (FDU) and uridine. Following FDU treatment, neurons were cultured in neurobasal medium with Glutamax and B27 supplement. One half volume of media was replaced every 48h. Purity of cell type specific cultures was assessed by immunolabeling for cell-type specific markers, including Iba-1 for microglia, GFAP for astrocyte and MAP2, neurofilament, and synaptophysin for neurons. CHME-5 microglia-The microglia cell line CHME-5 was kindly provided by Dr. Randal Davis from Oklahoma State University. It was originally obtained from human fetal microglia (Peudenier et al. 1991) transfected with the T-antigen of SV-40 virus (Janabi et al. 1995). Cells were cultured to 70% confluence in Dulbecco's modified Eagle's medium (DMEM) (Sigma Chemical Company, St. Louis, MO) supplemented with 5% inactivated Zenón et al.

Q: Paragraph: Arboviruses are often maintained in complex cycles involving vertebrates such as mammals or birds and blood-feeding mosquitoes. However, the role of wildlife hosts in their emergence or re-emergence in human populations has received little attention. The recent emergence of Zika virus in America, and previous occurrences of chikungunya and dengue, forces us to confront a potential new disease-emergence phenomenon. Using a spatial data mining framework to identify potential biotic interactions, based on the degree of co-occurrence between different species, we identified those mammal species with the highest potential for establishing mammal-vector interactions, considering as principal vector Aedes aegypti. Seven of the top ten identified mammal species with highest potential were bats, with two of them having previously been confirmed as positive hosts for dengue in Mexico. We hope that this will raise interest of Mexican public health authorities and academic institutions to assess the role of wild hosts in the maintenance and spread of arboviruses.
