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). Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc.

A fundamental, but unanswered question in host-pathogen interactions is the timing, localization and population distribution of virulence gene expression during infection. Here, microarray and in situ single cell expression methods were used to study Vibrio cholerae growth and virulence gene expression during infection of the rabbit ligated ileal loop model of cholera. Genes encoding the toxin-coregulated pilus (TCP) and cholera toxin (CT) were powerfully expressed early in the infectious proces  ...[more]
