| tissue-specific gene expression identifies a gene in the lysogenic phage gifsy-1 that affects salmonella enterica serovar typhimurium survival in peyer's patches. | in vivo expression technology was used to identify salmonella enterica serovar typhimurium genes that are transcriptionally induced when the bacteria colonize the small intestines of mice. these genes were subsequently screened for those that are transcriptionally inactive during the systemic stages of disease. this procedure identified gipa, a gene that is specifically induced in the small intestine of the animal. the gipa gene is carried on the lambdoid phage gifsy-1. consistent with the expre ... | 2000 | 10913072 |
