Cytotoxin k
WebTo investigate the basis for this phenomenon, we analyzed the transcription of the vacuolating cytotoxin gene (vacA) in eight Tox1 strains (each with a type s1/m1 vacA genotype) and nine Tox2 strains (each with a type s2/m2 vacA genotype). Most of the Tox1 and Tox2 strains tested used the same vacA transcriptional start point, WebKlebsiella oxytoca is an opportunistic pathogen which damages intestinal epithelium through producing cytotoxin tilivalline. This toxin plays a role in the pathogenesis of bacteria and is the main virulence factor which leads to antibiotic-associated hemorrhagic colitis progress.
