Fungal Infections of Ventriculi in Captive Birds

Abstract

Ventricular candidiasis was the apparent cause of death in 14 of 21 captive birds, and incriminated in six others. No clinical signs were recognized in 14 of the 21 birds prior to death, and in four of the 21, no other gross or microscopic lesions were documented. Microscopic lesions included colonization of the koilin layer of the ventriculi by fungi with occasional penetration into the glandular epithelium. No conclusive pattern of infection by family of birds was detected.

Pathogenic microorganisms carried by migratory birds passing through the territory of the island of Ustica, Sicily (Italy)

“…All of the yeasts isolated in the present study were potential pathogenic fungi that can induce cutaneous and/or systemic animal and human diseases (Monga & Garg, 1980;Hubbard et al, 1985;Thakur et al, 2007;Castellá et al, 2008;Perfect et al, 2010;Ortega et al, 2011).…”

Mallards (Anas platyrhynchos) staying in urban environments have higher levels of microfungi biota diversity than do birds from non-urban areas

“…Outbreaks of fungal diseases have been noted both in birds held in captivity (Hubbard et al, 1985;Wolff et al, 1992) and in wild birds (e.g. Burr, 1981;Windingstad et al, 1989;Souza and Degernes, 2005;Rippon et al, 2012), as well in poultry (Akan et al, 2002;Khosravi et al, 2008;Lanteri et al, 2012).…”

Causas de morte em Passeriformes: comparação entre aves de vida livre residentes na Região Metropolitana de São Paulo e aves oriundas do tráfico

“…Normalmente o trato gastrintestinal é o mais frequentemente acometido, principalmente cavidade oral, inglúvio, esôfago, proventrículo, ventrículo e intestino delgado, mas já houve relatos de acometimento em seios e cavidade nasal, bico, pele, cloaca, trato respiratório, globo ocular, glândula uropigiana e até sistêmico (HUBBARD et al, 1985;BAUK, 1994;SPIRA, 1996;OGLESBEE, 1997;VELASCO, 2000). Segundo pesquisa realizada por , a cavidade nasal também pode atuar como uma importante porta de entrada e sítio de multiplicação para a doença em Passeriformes e Psittaciformes, sendo a região vestibular mais afetada, induzindo a uma lesão hiperqueratótica na cavidade nasal, assim como no inglúvio, ventrículo e cloaca.…”
