Abstract:
Four chromogenic media were compared for their ability to detect urinary tract pathogens in 299 urine specimens, of which 175 were found positive, allowing the growth of 279 microorganisms. After 18 to 24 h of incubation, the CPS ID4, CPSE, CPSO (bioMérieux), and UriSelect4 (Bio-Rad) media showed sensitivities of 97.1%, 99.3%, 99.6%, and 99.6%, respectively.
