Resumo

Erysipelothrix rhusiopathiae causes a variety of diseases in many animal species, including human beings. Most human infections caused by this pathogen are related to occupational exposure, and swine are considered to be the most important reservoir of E. rhusiopathiae. The white-lipped peccary (Tayassu pecari) is an ungulate that has some genetic relationship to swine, and since the demand for T. pecari meat has recently increased in Brazil and nothing is known about the relationship of this peccary with the occupational zoonotic agent, E. rhusiopathiae, an investigation on the matter was conducted. Tonsils from 21 T. pecari slaughtered in southern Brazil were examined, and one animal was positive for E. rhusiopathiae isolation. Five colonies of this positive specimen had their species identity confirmed by PCR, and were characterized by serotyping, broth microdilution susceptibility test, and pulsed field gel electrophoresis (PFGE). All colonies belonged to serotype 2b, and presented identical susceptibility profiles. Nevertheless, the five colonies showed three different PFGE profiles, demonstrating the occurrence of infection by different E. rhusiopathiae genotypes. This is the first report of E. rhusiopathiae infection in T. pecari as well as the first description of animals carrying different E. rhusiopathiae genotypes. (AU)
