Transcription profiling of Vibrio cholerae strain N16961 was incubated with crab shell in artificial sea water media for 24 hours

ABSTRACT: Strain N16961 was incubated with crab shell in artificial seawater media for 24 hours. cDNA from 1 ug RNA was labeled with Cy3 (planktonic bacteria) and Cy5 (crab attached bacteria).

Chitin, an insoluble polymer of GlcNAc, is an abundant source of carbon, nitrogen, and energy for marine microorganisms. Microarray expression profiling and mutational studies of Vibrio cholerae growing on a natural chitin surface, or with the soluble chitin oligosaccharides (GlcNAc)(2-6), GlcNAc, or the glucosamine dimer (GlcN)2 identified three sets of differentially regulated genes. We show that (i) ChiS, a sensor histidine kinase, regulates expression of the (GlcNAc)(2-6) gene set, including ...[more]

Comparative genomic hybridization of Vibrio cholerae which have converted from serogroup 01 to 0139 (phage selected) - part 2

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. Mukerjees 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: AIIIpO139#1 / AIIIpO139#3 / AIIIpO139#4 / AIIIpO139#5 are four clones analyzed after the second experiment; AIVpO139#2 / AIVpO139#4 / AIVpO139#5 / AIVpO139#8 are four clones analyzed after the fourth independent experiment. Two MA replicates for each clone were done.
