Project description:Question Addressed: What is the level of expression of genes in Vibrio cholerae recovered from various conditions. These conditions include samples recovered directly from patients (O139 from stool samples from ICDDR,B and N16961 from stool samples from a vaccine trial held in Cincinnati) as well as standard logarithmic and stationary phase grown bacteria. Labeling reactions were performed in duplicate for each stool derived and in quadruplicate for each in vitro grown strain. A common reference was used for each slide, it was composed of RNA from the exponentially growing 92A1552 V. cholerae strain

Project description:These experiments were performed to show serogroup conversion in Vibrio cholerae from O1 to O139 in a mixed communities / biofilms. For this purpose, V. cholerae O1 El Tor A1552 and VCO139-Kan strain (a MO10 derivative; O139 serogroup) were grown on crab shell fragments to induce natural competence for transformation. Transformants were selected on LB+Kan+Rif plates. O139 positive transformants have undergone a full exchange of the O1 region by the O139 region. This implies an exchange of an at least 32 kb spanning O1 genomic region by more than 42 kb of the O139 region. The transformation experiment was done at least five independent times; data from four experiments are shown; per experiment one to three clones were analysed by CGH with two experimental replicates each.

Project description:Temperature is a crucial environmental signal that govers the occurrence of Vibrio cholerae and cholera outbreaks. To understand how temperature impacts the transcriptome of V. cholerae we performed whole-genome level transcriptional profiling using custom microarrays on cells grown at human body temperature (37 C) then shifted to temperatures V. cholerae experience in the environment (15 C and 25 C).

Project description:This study is an analysis of changes in gene expression during stringent response in Vibrio cholerae. V. cholerae cells in mid-log were treated with serine hydroxamate and gene expression was compared to untreated cells. Keywords: Stress response, stringent response

Project description:These experiment were performed to show a serogroup conversion in Vibrio cholerae from O1 to O139. For this purpose, V. cholerae O1 WT = A1552 was grown on crab shell fragments to induce natural competence for transformation. Purified DNA (2 ug each) from strain VCO139-Kan was added after 24h and the cells grwon further for 24h. The VCO139-Kan strain is a MO10 derivative (both O139 serogroup) which harbors a Kanamycin cassette in the O139 region (as part of the operon between wbfA and wbfB w/o own promotor) for better selection. Transformants were selected on LB+Kan plates. Two groups of transformants were gained: Group I had a full exchange of the O1 region by the O139 region (clones serogroup-converted: SGC#1-3); the crossovers for the homologous recombination event had occurred within or upstream of the gmhD gene and in most instances within or downstream of the homolog gene of VC0271. This implies an exchange of an at least 33 kb spanning O1 genomic region by more than 42 kb of the O139 region. Group II had only half of the O139 region transfered and therefore half of the O1 region kept (clones HSGC#4-6). We analyzed their genotype and found that all of them had undergone a homologous recombination event with one crossover in or upstream of the gmhD gene and the second one inside the VC0254 and IS1358 gene. The transformation experiment was done three independent times (I - III). Three clones from group I and group II were selected from each experiment and analyzed by microarray hybridization (BioPrime. Array CGH Genomic Labeling from Invitrogen). Two microarray replicates were done per clone.

Project description:To determine transcriptome differences in Vibrio cholerae when grown as planktonic and biofilm cultures, whole-genome level transcriptional profiling was performed using RNAseq analysis. Transcriptomes of biofim and planktonic cultures were compared in this study.

Project description:These experiments were performed to show a serogroup conversion of Vibrio cholerae from O1 to O139. For this purpose, V. cholerae O1 El Tor (A1552) was grown on crab shell fragments to induce natural competence for transformation. Purified DNA (4 ug each) from strain MO10, an O139 serogroup strain, was added after 24h and the cells were further grown for 24h. After detachment from the crab shell fragments, bacteria were poured into soft-agar and overlaid onto LB plates. Mukerjee's El Tor phage V (a gift of Dr. M.S. Islam) was dropped onto the surface of the bacteria containing soft-agar. The plaques formed by killing non-transformed A1552 cells possessed resistant clones which were picked and further selected for opaque morphotype and agglutination by O139-specific antiserum. Four clones were selected from each independent experiment and analyzed by microarray hybridization (BioPrime. Array CGH Genomic Labeling from Invitrogen). Two microarray replicates were done per clone. Strain Names: ApO139#2 / ApO139#4 / ApO139#6 / ApO139#8 are four clones analyzed after the first experiment; AIIpO139#3 / AIIpO139#4 / AIIpO139#5 / AIIpO139#6 are four clones analyzed after the second independent experiment. Two MA replicates for each clone were done. CGHs of A1552 versus MO10 are provided as control. Keywords: array CGH
