Microarray analysis of V. cholerae genes differentially expressed in 8h rabbit ileal loop fluid.

ABSTRACT: Transcriptional analysis of wild-type V. cholerae isolated from the rabbit ileal loop was performed by quickly pelleting bacteria from the fluid accumulated in the ileal loops after 8 h of infection. The bacteria were then resuspended in Trizol reagent and frozen on dry ice. The wild-type bacteria from three independent experiments in three different rabbits were analyzed. RNA was isolated from the Trizol agent, treated with DNaseI (Ambion, Austin, Texas, United States), and cleaned by using the RNeasy kit (Qiagen, Valencia, California, United States).

Transcription profiling of Vibro cholerae from rabbit ileal loop fluid 12 h post infection to identify differentially expressed genes

Project description:Transcriptional analysis of wild-type V. cholerae isolated from the rabbit ileal loop was performed by quickly pelleting bacteria from the fluid accumulated in the ileal loops after 12 h of infection. The bacteria were then resuspended in Trizol reagent and frozen on dry ice. The wild-type bacteria from two independent experiments in two different rabbits were analyzed. RNA was isolated from the Trizol agent, treated with DNaseI (Ambion, Austin, Texas, United States), and cleaned by using the RNeasy kit (Qiagen, Valencia, California, United States). Labeling of cDNA and microarray hybridizations were performed as described [Yiliz et al. 2001, Mol. Micro. 53: 497-515]. Microarrays were scanned with a GenePix 400A instrument (Axon Instruments), using the GENEPIX 5.0 software.

Transcription profiling of Vibrio cholerae wild type, hapR and rpoS deletions in mid-exponential or stationary phase concluding that rpoS controls the Vibrio cholerae mucosal escape response

Project description:For expression analysis of wild-type V. cholerae, hapR, and rpoS deletion mutants in mid-exponential or stationary phase, the strains were grown to either OD600 of 0.3 or for 11 h in LB media at 37 0C, and bacteria from 2-ml culture were quickly pelleted, resuspended in Trizol reagent (GIBCO/BRL, San Diego, California, United States), and frozen on dry ice. RNA was isolated from the Trizol agent, treated with DNaseI (Ambion, Austin, Texas, United States), and cleaned by using the RNeasy kit (Qiagen, Valencia, California, United States). Labeling of cDNA and microarray hybridizations were performed as described [Yiliz et al. 2001, Mol. Micro. 53: 497-515]. Microarrays were scanned with a GenePix 400A instrument (Axon Instruments), using the GENEPIX 5.0 software. At least four microarray experiments were performed for each of two biological replicates for the tested strains. Gene expression of V. cholerae, rpoS, and hapR deletion mutants in stationary phase LB cultures was analyzed and compared to the wild-type parent under identical conditions. Gene expression of the wild-type parent during stationary phase after 11 h growth in LB was analyzed using RNA from an exponentially growing culture as a reference.

Microarray analysis of V. cholerae genes differentially expressed in 12 h rabbit ileal loop mucus

Project description:The mucus and cell-associated bacteria were isolated as a single fraction from ileal loops twelve hours post inoculation by scraping the epithelial surface of the intestine with a disposable plastic cell scraper after the loops had been cut open and gently rinsed in PBS buffer to wash away remaining luminal fluid. The mucus gel/cell associated fraction was suspended in Trizol and frozen on dry ice. Total RNA, which includes RNA from the infecting bacteria and from the host (see below), was isolated from the thawed Trizol suspension, treated with DNaseI (Applied Biosystems, Austin, TX) and cleaned by using the RNeasy kit (Qiagen, Valencia, CA).
