ABSTRACT

Objetivou-se com este estudo comparar genotipicamente 35 isolados de Corynebacterium pseudotuberculosis recuperados de conteúdo de abscessos de caprinos e ovinos com linfadenite caseosa, procedentes de cinco municípios localizados no Sertão de Pernambuco, Brasil. Utilizou-se a técnica de fingerprint RFLP-PCR com as enzimas de restrição Hpy-Ch4 e Msp1 aplicada ao gene rpoB e as enzimas Pst I e Msp I para o gene pld. Não houve diferença nos padrões de fragmentos de bandas entre os isolados, independente da espécie hospedeira ou da área geográfica estudada, definindo-se um padrão genotípico homogêneo de C. pseudotuberculosis responsável por abscessos superficiais na região.(AU)


The objective was to genotypically compare 35 samples of Corynebacterium pseudotuberculosis obtained from abscesses of sheep and goats diagnosed with caseous lymphadenitis originated from 5 different municipalities in the semi-arid region of Pernambuco, Brazil. The RFLP-PCR technique with Hpy-Ch4 and Msp I and Pst I Msp I restriction enzimes was used to fingerprint the genes rpoB and pld, respectively. The results demonstrate that there was no difference on the fragments banding pattern among samples, independently of the host species or geographic area studied, defining a homogeneous profile of C. pseudotuberculosis responsible for superficial abscesses for the region.(AU)
