E-mail: jackeline.an.medvet@gmail.com Candidiasis is a frequent disease caused by yeasts of Candida spp., that acts either like primary or secondary agent for humans and aviary important disease. This article carried out data analysis from 599 laboratory avian samples sent for microbiology analysis in a commercial diagnostic laboratory located in Poços de Caldas city-Minas Gerais state in Brazil, from 2010 to 2014 period with respect to seasonality and geographic distribution. All avian orders analysis from all geographic areas studied reveled 28.05% positives results (168/599) e 71.95% negatives results (431/599), distributed by seasonality 19.9% (119/599) at summer, 30.6% (183/599) in autumn , 28.04% (168/599) in winter and 21.54% (129/599) in springs. At summer 31.09% (37/119) were positives for Candida sp.; 31.15% (57/183) in autumn; 30.4% (51/168) in winter at last 17.83% (23/129) in springs. Results revealed at Q-square statistic test (p<0.05) significant reduction in occurrence at springs (p=0.03) possible due to an increased immunocompetence at this time but more studies are necessary to better understanding this finding.

E-mail: jackeline.an.medvet@gmail.com Candidíase é a doença causada pelas leveduras do gênero Candida spp., agindo tanto como agentes primários ou secundários de doenças importantes em aves e humanos. O presente estudo teve por objetivo estudar as 599 amostras com pedido de diagnóstico para Candida spp. em um laboratório diagnóstico comercial na cidade de Poços de Caldas, MG-Brasil, no período de 2010 à 2014, levando em consideração a sazonalidade (verão, outono, inverno e primavera) e origem geográfica das amostras. Ao analisar o grupo com todas as ordens de aves em todo território brasileiro, foram 28,05% resultados positivos (168/599) e 71,95% resultados negativos (431/599), sendo 19,9% (119/599) dos resultados obtidos no verão, 30,6% (183/599) no outono, 28,04% (168/599) no inverno e 21,54% (129/599) na primavera. Dentro dos resultados obtidos, no verão 31,09% (37/119) foram positivos; no outono 31,15% (57/183); no inverno 30,4% (51/168) e por fim, na primavera 17,83% (23/129) (Quadro 3), tendo sido demonstrada baixa incidência nesta última estação (p=0,003) pelo teste de Qui-Quadrado. Com base nestes achados conclui-se que durante a primavera, há diminuição da incidência de resultados positivos para Candida spp. possivelmente devido a um aumento da imunocompetência destes animais durante esta estação, sendo necessários mais estudos para associar resultados clínico-práticos aos estatísticos encontrados nesta pesquisa.

ABSTRACT.- Renata G. Vieira R.G. & Acqua Coutinho S.D. 2009. Phenotypical characterization of Candida spp. isolated from crop of parrots (Amazona spp.). Pesquisa Veterinária Brasileira 29(6):452-456. Curso de Pós-Graduação em Imunopatologia Veterinária da Universidade Paulista, Rua Agariba 48, São Paulo, SP 05053-010, Brazil. E-mail: selene@uol.com.br The purpose of this study was to characterize Candida isolates from crop of parrots. Forty baby parrots of genus Amazona, species aestiva and amazonica that were apprehended from wild animal traffic were used: 18 presented ingluvitis and 22 other alterations, but showing general debilitation. Samples were seeded on Sabouraud dextrose agar with chloramphenicol after be obtained by the introduction of urethral probe through the esophagus. Based on morphology and biochemical reactions (API 20C) Candida was confirmed; it was still searched the production of proteinase and phospholipase, virulence factors for Candida species. Candida spp. were isolated from 57.5% parrots, being 72.2% from birds with ingluvitis and 45.5% from without ones. Twenty-five strains of Candida were isolated, 60% and 40%, respectively from parrots with and without ingluvitis, and were speciated: 28% C. humicola, 24% C. parapsilosis, 20% C. guilliermondii, 20% C. famata, and 8% C. albicans. These results demonstrate that C. albicans is not the most frequent species isolated, and it is the first report that shows C. guilliermondii, C. famata, and C. humicola causing infection in parrots. Many isolates presented filamentation (76%), 100% produced proteinase and 68% phospholipase. The observation of Candida spp. producing virulence factors reinforce the pathogenic role of these yeasts in the cases studied.
