| genomic characterization of wild-type measles viruses that circulated in different states in brazil during the 1997 measles epidemic. | despite the marked reduction in the incidence of measles in brazil, a measles epidemic occurred in this country in 1997. the measles cases observed during this epidemic began to reappear in large numbers in são paulo, and spread to rio de janeiro and other brazilian states. in the present study molecular biology techniques were used for the detection and genomic characterization of measles viruses from clinical samples such as urine and nasopharyngeal secretions collected in the states of rio de ... | 2001 | 11241461 |
| fusarium spp. as agents of onychomycosis in immunocompetent hosts. | fusarium spp. are nondermatophyte filamentous fungi, frequently reported as an etiologic agent of opportunistic infections in humans; however, their involvement in the etiology of cutaneous lesions is still debatable, especially in immunocompetent patients, where they are often considered as contaminant fungi. | 2007 | 17651164 |
| cryptococcus neoformans isolated from passerine and psittacine bird excreta in the state of paraná, brazil. | cryptococcus neoformans is an opportunistic basidiomycete yeast that causes life-threatening infections as meningoencephalitis primarily in immunocompromised hosts, generally associated with aids. the source of this organism is mainly pigeon excreta; however, other avian species' excreta are implicated as a source of this yeast. the occurrence of c. neoformans and cryptococcus gattii in bird excreta in the state of paraná in brazil was determined in this study. a total of 141 samples of passerin ... | 2008 | 18459065 |
