Ocorrência de genes tad associados à formação de biofilme em isolados de Pasteurella multocida de pulmões de suínos com pneumonia

Abstract: Os atuais sistemas de criação intensiva de suínos aumentam a pressão de seleção microbiana propiciando a disseminação de doenças respiratórias. A bactéria Pasteurella multocida é associada a diversas patologias respiratórias em animais submetidos a esse tipo de criação, causando grandes perdas econômicas. A formação de biofilme foi descrita in vitro em P. multocida e fatores analisados indicaram a facilitação na colonização dos tecidos, aumentando a resistência às defesas do hospedeiro e aos antibióticos. Os o… Show more

“…Biofilm formation may also function as a survival mechanism under adverse conditions in less virulent strains or with P. multocida involved in secondary infections. For example, P. multocida can colonize swine lungs in the form of biofilms, causing lesions that are generally difficult to tre- at because of the blockade of antimicrobial action and the monocyte phagocytic system (Donlan & Costerton 2002, Moraes et al 2014. Despite these results, the correlation of biofilm formation capacity with the pathogenicity of a given strain should be further evaluated in future studies with a larger number of strains classified as strong biofilm producers.…”

“…Pasteurella multocida is a Gram-negative bacillus that causes economic losses associated with numerous respiratory diseases in poultry farms (Moraes et al 2014) and, in some cases, the processing of animal products (Ribeiro et al 2012). P. multocida causes fowl cholera (FC) as well as progressive atrophic rhinitis, pneumonia and serositis in swine, hemorrhagic septicemia in cattle and pasteurellosis in rabbits , Ferreira et al 2012, Wilkie et al 2012.…”
