Abstract

This study reported the pulmonary, microbiological, and hematological alterations in Crotalus durissus terrificus parasitized by nematodes of the genus Rhabdias. Histological, microbiological, and hematological analysis were performed on parasitized (n=6) and non-parasitized (n=6) snakes. Granulocytic and mononuclear cell infiltrates in the pulmonary parenchyma and epithelium were also observed during the histological analysis of parasitized snakes. Microbiological analysis of parasitized animals revealed the following Gram-negative bacteria: Citrobacter divergens, Burkholderia cepacia, Stenotrophomonas maltophilia, Proteus vulgaris, Enterobacter sakazakii, Enterobacter ammnigenus, Pseudomonas aeruginosa, Pantoea sp. and Providencia rettgeri. In non-parasitized snakes, the following species were identified: B. cepacia, Pseudomonas fluorescens, and Acinetobacter baumanii. Increased levels of plasmatic protein, decreased lymphocyte counts, and normal red blood cell values were observed in parasitized animals.<br>Este trabalho relata as alterações pulmonares, microbiológicas e hematológicas em Crotalus durissus terrificus parasitadas pelo nematódeo do gênero Rhabdias. As análises histológicas, microbiológicas e hematológicas foram realizadas em serpentes parasitadas (n=6) e não parasitadas (n=6). Foram observados infiltrados de células granulocíticas e mononucleares no parênquima pulmonar durante a análise histopatológica das serpentes parasitadas. A análise microbiológica revelou as seguintes bactérias Gram-negativas; Citrobacter divergens, Burkholderia cepacia, Stenotrophomonas maltophilia, Proteus vulgaris, Enterobacter sakazakii, Enterobacter ammnigenus, Pseudomonas aeruginosa, Pantoea sp. e Providencia rettgeri. Nas serpentes não parasitadas foram identificadas: B. cepacia, Pseudomonas fluorescens e Acinetobacter baumanii. Nos animais parasitados observaram-se: aumento da concentração de proteína plasmática, diminuição da contagem de linfócitos, e valores normais de hematimetria
