title: Pyelonephritic potential of Pseudomonas aeruginosa in ascending mouse model.
abstract: The suitability of female BALB/c and Swiss Webster (LACA) strains of mice for an ascending model of pyelonephritis for human uroisolate of Pseudomonas aeruginosa, was assessed. A fresh isolate of Ps. aeruginosa elaborating virulence factors like elastase, protease, phospholipase C, pyochelin and haemolysin was selected and introduced transuretherally in mice without any manipulation of the urinary tract. This isolate was able to colonize and persist in the renal tissue till day 12 post infection. Histopathologically, severe renal lesions i.e., abscesses formation was observed. The LACA strain was found to be more susceptible to infection with the selected Ps. aeruginosa isolate.
