In vitro virulence evaluation of clinical and environmental isolates of dermato...
Bonci, Mário Mendes; Makita, Mário Tatsuo; Mendes, Clara de Almeida; Abreu, Daniel Paiva Barros de; Ribeiro, Laís VillarDermatophytes are keratinophilic fungi and the causative agent of dermatophytosis in animals and people. In the pathogenesis of this disease, enzymes such as DNase, gelatinase, lipase, keratinase, elastase, and collagenase are highlighted. This work aimed to verify the production of these enzymes by clinical and environmental isolates of dermatophytes. Environmental strains were obtained by the Vanbreuseghem te...

Cardoso, Pedro Henrique Magalhães; Moreno, Andrea Micke; Moreno, Luisa Zanolli; de Oliveira, Carolina Helena; Baroni, Francisco de AssisPeixes ornamentais de aquário representam um grande segmento no mercado de animais de estimação, no qual Estados Unidos, Europa e Japão dominam. São aproximadamente 1.500 espécies de peixes marinhos e em torno de 4.500 de espécies de água doce comercializados com fins ornamentais. O peixe é a quarta espécie mais comum nos domicílios brasileiros. Peixes ornamentais de aquário são comercializados e distribuídos e...
Cryptococcus neoformans strains isolated from church towers in Rio de Janeiro C...
Baroni, Francisco de Assis; Paula, Claudete Rodrigues; Silva, Ériques Gonçalves da; Viani, Flávio Cesar; Rivera, Irma N.G.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...
An evaluation of manual and mechanical methods to identify Candida spp. from hu...
Oliveira, Geraldo dos Santos; Ribeiro, Elizabeth Teixeira; Baroni, Francisco de AssisTo compare two yeast identification methods, i. e, the manual and the VITEK mechanical methods, 62 clinical samples from hemocultures and animal sources were analyzed. After identification as Candida yeasts by the VITEK method, the strains were recharacterized using manual assimilation methods and sugar fermentation tests. Our findings reveal 58% concurrent identification between the two methods for animal stra...
