In vitro activity of amphotericin B, fluconazole and voriconazole against 162 Cryptococcus neoformans isolates from Africa and Cambodia.

In order to determine the potential role that various antifungal agents might have in the management of cryptococcosis in tropical areas, the in vitro susceptibility of Cryptococcus neoformans isolates from Africa ( n=52) and Cambodia ( n=110) to three antifungal agents (amphotericin B, fluconazole and voriconazole) were compared using the E-test method. The results of this study (i) confirm the value of the E-test for testing the in vitro susceptibility of C. neoformans towards voriconazole; (ii) provide the first evidence demonstrating good activity of amphotericin B, fluconazole and voriconazole against Cambodian isolates; and (iii) show there are differences in susceptibility between African and Asian C.

Prevention of Candida colonization prevents infection in a neonatal unit.

This study represents a 1-year surveillance period using our epidemiology-based principles published and successfully followed since 1979: weekly culture for yeasts of oral and anal swabs, treatment with oral nystatin of all colonized newborns, and good hygiene/handwashing. Colonization was demonstrated in 23 out of 791 newborns admitted from October 1998 to September 1999. Twenty-two strains of Candida were identified: 16 C.
