Fungi isolated rrom the excreta of wild birds in screening centers in pelotas, rs, Brazil / Fungos isolados de excretas de aves silvestres em centro de reabilitação em Pelotas, RS, Brasil

The identification of the fungal species belonging to the healthy microflora in animals is a precondition for the recognition of pathological processes causing them. The aim of this study was to investigate the presence of potentially pathogenic fungi in the feces of wild birds collected in Screening Centers. Samples were collected from the feces of 50 cages with different species of birds. The samples were processed according to the modified method STAIB and the plates incubated at 32 °C for up to ten days with daily observation for detection of fungal growth. The isolation of the following species was observed: Malassezia pachydermatis, Candida albicans, C. famata, C. guilliermondii, C. sphaerica, C. globosa, C. catenulata, C. ciferri, C. intermedia, Cryptococcus laurentii, Trichosporon asahii, Geotrichum klebahnii, Aspergillus spp., A. niger and Penicillium spp. Knowing the character of some opportunistic fungi is important in identifying them, facilitating the adoption of preventive measures, such as proper cleaning of cages, since the accumulation of excreta may indicate a risk for both health professionals and centers for screening public health.

A identificação das espécies de fungos pertencentes à microbiota saudável em animais é pré-condição para o reconhecimento dos processos patológicos causados por esses. O objetivo deste estudo foi investigar a presença de fungos potencialmente patogênicos nas fezes de aves selvagens coletadas em Centros de Triagem. Foram coletadas amostras de fezes de 50 gaiolas com diferentes espécies de aves. As amostras foram processadas de acordo com o método modificado STAIB e as placas foram incubadas a 32 °C por até dez dias, com observações diárias para detecção do crescimento dos fungos. Observamos o isolamento de espécies: Malassezia pachydermatis, Candida albicans, C. famata, C. guilliermondii, C. sphaerica, C. globosa, C. catenulata, C. ciferri, C. intermedia, Cryptococcus laurentii, Trichosporon asahii, Geotrichum klebahnii, Aspergillus spp., A. niger e Penicillium spp. Conhecendo o caráter de alguns fungos oportunistas resalta-se a importância para identificá-los, facilitando a adoção de medidas preventivas, como a limpeza adequada das gaiolas, uma vez que a acumulação de excrementos pode indicar um risco tanto para os profissionais de saúde e centros de triagem de saúde pública.

Isolation of dermatophytes in wild felids from screening centers.

The aim of this study was detect the presence of dermatophyte fungi on wild felids from screening centers. Samples were taken from 30 animals, assembled in two groups: "free-ranging" and "transitory captivity". The dermatophytes (Trichophyton genus), isolated from two felids (6.6%), both of the group "free-ranging".

Nematode parasites of Chelidae (Testudines) from southern Brazil.

The presence of helminths associated with freshwater turtles is rarely reported. There are no records of nematodes parasitizing Acanthochelys spixii, and for Hydromedusa tectifera, there is only the report of unidentified nematodes found in this species in Argentina. This is the first report of nematodes (Spiroxys contortus and Camallanus sp.) in A. spixii and the first record of Spiroxys contortus and Camallanus sp. in H. tectifera. This is the southernmost record of S . contortus because this nematode was previously recorded only in Mexico.
