Ocorrência de Chlamydia Psittaci em aves de vida livre em área do bioma mata atlântica, Bahia

Abstract

Chlamydia psittaci (C. psittaci) is the etiologic agent of a highly infectious zoonosis that mainly affects birds of the orders Psittaciformes and Columbiformes, although it has already been described in more than 467 species of domestic and free-living birds in the world. Most human cases have been reported in association with the presence of birds, being considered one of the main zoonoses that has birds as a source of infection. The frequency of infection by C. psittaci was evaluated in different species of Atlantic Forest birds in the Serra da Jiboia region, Bahia, Brazil, where 111 birds belonging to the orders Passeriformes (89), Columbiformes (7), Apodiformes ( 6), Caprimulgiformes (4), Psittaciformes (3), Galbuliformes (2), of 55 different species. Cloaca and oropharynx swabs were collected for the molecular diagnosis of Chlamydia by means of a sample pool of each specimen. The study revealed that C. psittaci has free-living avian hosts, with six specimens positive for Chlamydia sp. (5.40%, 6/111) and of these, two individuals (Myiophobus fasciatus and Ceratopipra rubrocapilla), were positive for C. psittaci (33.33%, 2/6) representing 1.80% (2/111) of total population studied. The presence of the bacteria in this avifauna population confirms the circulation of the agent in the wild and the need for further studies on the spread of Chlamydia in the Atlantic Forest Biome and its possible interactions with captive birds and poultry breeding in the surrounding rural areas. the forest.
