Project description:A microarray was developed to screen rodent samples for pathogens of zoonotic importance In the work described here, a homologue to Yersinia pestis was found in rodent samples after screening with the microarray A number of rodent samples from the UK and Canada were identified as carrying a homologue to a Yersinia pestis gene

Project description:Temperature is a key environmental factor for facultative pathogens during the host adaptation response. To assess the functional role of temperature in Yersinia pestis, a microarray study was conducted comparing the Δpgm (pigmentation-negative) R88 strain grown at 37°C or 30°C.
Project description:The etiologic agent of bubonic plague, Yersinia pestis, senses cell density-dependent chemical signals to synchronize transcription between cells of the population in a process named quorum sensing. Though the closely related enteric pathogen Y. pseudotuberculosis uses quorum sensing system to regulate motility, the role of YpeIR quorum sensing in Y. pestis has been unclear. YpeIR is one of the AHL quorum sensing system in Y. pestis. In this study we performed transcriptional profiling experiments to identify Y. pestis YpeIR quorum sensing regulated functions at 37°C.
