Abstract
in English, French

A high mortality outbreak of respiratory mycoplasmosis occurred in goats in Mexico. The clinicopathologic presentation resembled contagious caprine pleuropneumonia caused by Mycoplasma capricolum subspecies capripneumoniae. By using a battery of polymerase chain reaction assays, the mycoplasma associated with this outbreak was identified as Mycoplasma mycoides subsp. capri.

Mycoplasma mycoides subsp. capri associé à la maladie respiratoire de la chèvre et à un taux élevé de mortalité dans les troupeaux. Une flambée de mycoplasmose respiratoire présentant une mortalité élevée a atteint des chèvres au Mexique. Les signes clinicopathologiques ressemblaient à la pleuropneumonie caprine contagieuse causée par Mycoplasma capricolum subsp. capripneumoniae. Par une batterie de tests d’amplification en chaîne par polymérase, Mycoplasma mycoides subsp. capri a été identifié comme responsable de cette flambée.

Polymerase chain reaction products obtained after amplification of template DNA from mycoplasma isolates recovered from Mexican goats with respiratory disease (A) and from reference mycoplasma strains (B), using the MmF-MmR primer pair, which target sequences of the Mycoplasma mycoides cluster (7); and the corresponding PstI digestion products of the 548 bp amplicons seen in A (C). MW: Molecular weight ladder, 50 bp; 1–7: Mycoplasma isolates from Mexican goats; F38 and GL102: M. capricolum subsp. capripneumoniae; USM: Unidentified sheep mycoplasma; PG3: M. mycoides subsp. capri; YG: M. mycoides subsp. mycoides Large Colony Type; Cal. Kid: M. capricolum subsp. capricolum.
