L'objectif principal de la présente étude était d'identifier les souches circulantes de Mycobacterium avium sous-espèces paratuberculosis (MAP) dans des échantillons fécaux obtenus de populations de chèvre laitière (N = 29 fermes) et de brebis laitière (N = 21 fermes) en Ontario, Canada. Du sous-typage supplémentaire a été effectué afin de déterminer s'il y avait suffisamment de diversité entre les souches qui permettrait d'établir des patrons de transmission de MAP. Il a été déterminé que le Type C était la souche dominante d'isolats de MAP (95,2 %) chez les chèvres laitières (n = 21), alors que deux isolats ovins ont été identifiés comme étant du Type S/sous-type III (n = 2). Le sous-typage des souches du Type C, basé sur le nombre variable de séquences répétées en tandem (VNTR) et les unités répétitives entrecoupées des mycobactéries, a permis d'identifier trois types de VNTR : INMV 1 (n = 10), INMV 2 (n = 10), et un type encore non-identifié (n = 1). Les méthodes actuelles de typage ne permettent de démontrer que peu de diversité de MAP dans la population de chèvre laitière et sont ainsi d'utilité limitée pour étudier les patrons d'infection.(Traduit par Docteur Serge Messier).
