In vitro antifungal susceptibility of Cryptococcus gattii.
We have determined the in vitro susceptibilities of 57 strains of Cryptococcus gattii to nine antifungal agents and have compared the MICs for these strains with those for C. neoformans. MICs were determined by a microdilution reference method. Albaconazole and ravuconazole (MICs of 0.04 and 0.05 microg/ml, respectively) showed the best activities. Micafungin showed no activity (MIC of >128 mic...
متن کاملSusceptibility of Cryptococcus neoformans biofilms to antifungal agents in vitro.
Microbial biofilms contribute to virulence and resistance to antibiotics by shielding microbial cells from host defenses and antimicrobial drugs, respectively. Cryptococcus neoformans was demonstrated to form biofilms in polystyrene microtiter plates. The numbers of CFU of disaggregated biofilms, 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazolium hydroxide reducti...
متن کاملIn vitro antifungal susceptibility of clinical isolates of Cryptococcus neoformans var. neoformans and C. neoformans var. gattii.
One of the differences observed between the two varieties of Cryptococcus neoformansis the greater difficulty to achieve an adequate therapeutical response in patients affected by C. neoformans var. gattii, an observation that has been validated in vitro only rarely. The aim of this work was to study the susceptibility patterns of 35 Colombian clinical isolates of C. neoformans, 20 of which bel...
متن کاملCorrelation of antifungal susceptibility and molecular type within the Cryptococcus neoformans/C. gattii species complex.
Members of the Cryptococcus neoformans/C. gattii species complex are grouped into eight molecular types, differing in their epidemiology, disease severity and geographic range. Recent in vitro antifungal susceptibility studies of isolates of the complex revealed contradictory results. The objective of the present study was to assess if this variation is random or correlates with different molec...
متن کاملCerebral infection caused by Cryptococcus gattii: a case report and antifungal susceptibility testing.
We report a clinical case of cerebral infection caused by Cryptococcus gattii in a 10 year-old boy. Clinical and laboratory exams did not demonstrate any apparent immunosuppressed state (HIV antibody and the tuberculin skin tests, both negative, were performed; blood cells count and immunoglobulin levels were within normality). Treatment was begun with amphotericin B-deoxycholate but renal toxi...
