| sporotrichosis: part ii. | sporotrichosis is a subcutaneous mycosis of implantation. it is the only subcutaneous mycosis for which direct examination or histology is of little or no value for diagnosis. the diagnosis solely rests on the isolation of sporothrix schenckii in culture. on pathologic examination, causative organisms are rarely seen. staining with fluorescent-labeled antibodies may aid in visualizing the cigar-shaped yeast forms; however, the organisms are still difficult to identify. topical therapy is not eff ... | 2010 | 21137636 |
| histopathology of cutaneous sporotrichosis in rio de janeiro: a series of 119 consecutive cases. | sporotrichosis is the most common subcutaneous mycosis in rio de janeiro. histopathological examination reveals diffuse granulomatous and suppurative dermatitis, and the fungus is rarely identifiable in tissue. we describe the histopathological features of cutaneous sporotrichosis, and investigate the association between them and the lack of visualization of the fungus. | 2010 | 20883452 |

| isolation and identification of fungi from vaginal flora in three species of captive leontopithecus. | the ability to reproduce in captivity is an essential component of lion tamarin (leontopithecus) conservation programs. however, infections such as vaginitis, cervicitis, and endometritis are important diseases that may influence the reproduction of these animals. therefore, it is important to detect continuous or occasional vaginal microbial populations, and to understand their potential role as an endogenous source of infection [collins, 1964; blue, 1983; pugh et al., 1986]. vaginal swabs were ... | 2004 | 15538760 |
| cryptococcus neoformans strains isolated from church towers in rio de janeiro city, rj, brazil. | cryptococcosis has been a significant cause of morbidity and mortality in patients with aids. many reservoirs of the agent cryptococcus neoformans have been reported, but the ecology of this yeast must be elucidated in order to establish surveillance programs and to prevent infections. the objective of this study was to evaluate the presence of c. neoformans in rio de janeiro city, rj, brazil. ten churches were selected for sampling and detection of the yeast collecting pigeon dropping, air samp ... | 2006 | 16699626 |
