Selection of bacterial virulence genes that are specifically induced in host tissues
Science, 1993•science.org
A genetic system was devised that positively selects for bacterial genes that are specifically
induced when bacteria infect their host. With the pathogen Salmonella typhimurium, the
genes identified by this selection show a marked induction in bacteria recovered from
mouse spleen. Mutations in all ivi (in vivo-induced) genes that were tested conferred a
defect in virulence. This genetic system was designed to be of general use in a wide variety
of bacterial-host systems and has several applications in both vaccine and antimicrobial …
