IDENTIFICAÇÃO DE KLEBSIELLA SPP. NAS FEZES DE PSITACÍDEOS CATIVOS
Knobl, Paloma; Viveiros, José Fernando; Franco, Letícia Soares; Davies, Yamê Minierio; Cunha, Marcos Paulo Vieira; Menão, Márcia CristinaMore than 80 species of birds belonged to the family Psittacidae in Brazil, including parrots, macaws and parakeets. The maintenance of these birds in Zoos may help the conservation of the species, but the captivity can favor intestinal colonization by enterobacteria. The aim of this study was to identify the presence of Klebsiella spp. in the fecal samples of captive parrots. Thirty - four fecal samples were a...
Gram-negative bacterium isolated from cardinals (Paroaria coronata and P. domin...
Cunha, Marcos Paulo Vieira; Guimarães, Marta Brito; Davies, Yamê Miniero; Milanelo, Liliane; Knöbl, TerezinhaAnualmente o tráfico de animais silvestres retira milhões de aves da natureza. Os cardeais (Paroaria coronata) e cardeais-do-nordeste (Paroaria dominicana) estão incluídos entre as espécies de aves mais traficadas. A microbiota cloacal de passeriformes de vida livre é composta principalmente por bacilos e cocos gram-positivos, já os bacilos gram-negativos predominam em aves de cativeiro. Em situações de estress...
Pesquisa de bactérias gram-negativas em canários-da-terra (Sicalis flaveola) re...
Davies, Yamê Miniero; Guimarães, Marta Brito; Milanelo, Liliane; Oliveira, Maria Gabriela Xavier de; Gomes, Vasco Túlio de MouraPasserines such as canaries or finches are the most unlawfully captured species that are sent to wildlife centers in São Paulo, Brazil. Captured birds may have infection by opportunistic bacteria in stressful situations. This fact becomes relevant when seized passerine are reintroduced. The aim of this study was to evaluate the health state of finches from illegal wildlife trade using microbiological approaches...
Salmonella Agona in Turkeys (Meleagris gallopavo) in commercial farms from Brazil
Oliveira, Mirela Caroline Vilela de; Cunha, Marcos Paulo Vieira; Oliveira, Maria Gabriela Xavier de; Filsner, Pedro Henrique de LimaSalmonella spp. is one of the major players involved in cases of foodborne diseases in humans and is responsible for significant losses in the poultry industry. The aim of this study was to investigate the presence of Salmonella spp. in feces of commercial turkeys from Brazil. Fecal swabs from 14 turkey farms (pool of six poults/flocks) were collected. The swabs were subject to the conventional bacteriological ...
Similaridade genética entre APEC e cepas de Escherichia coli isoladas de Guarub...
Prioste, Fabíola Eloisa Setim; Cunha, Marcos Paulo Vieira; Teixeira, Rodrigo Hidalgo Fricielle; Zwargg, Ticiana; Di-Chiacchio, Rosely GioiaThe role of psittacine birds as a reservoir of avian pathogenic Escherichia coli (APEC) is not known but would be helpful in understanding the human – animal interface, since the enteric microbiota of these birds consists of Gram positive bacteria. The aim of this study was to identify the presence of APEC in feces of clinically healthy Guaruba guarouba. To do this, we isolated and analyzed E. coli from cloacal...
