Characterization of Erysipelothrix rhusiopathiae isolated from Brazilian Tayassu pecari.
Summary of "Characterization of Erysipelothrix rhusiopathiae isolated from Brazilian Tayassu pecari."
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.

Medical and Biotech [MESH] Definitions
An infection caused by Erysipelothrix rhusiopathiae that is almost wholly restricted to persons who in their occupation handle infected fish, shellfish, poultry, or meat. Three forms of this condition exist: a mild localized form manifested by local swelling and redness of the skin; a diffuse form that might present with fever; and a rare systemic form associated with endocarditis.
Infections with bacteria of the genus ERYSIPELOTHRIX.
A genus of gram-positive, facultatively anaerobic, rod-shaped bacteria that has a tendency to form long filaments. Its organisms are widely distributed in nature and are found in MAMMALS; BIRDS; and FISHES. Erysipelothrix may appear gram-negative because they decolorize easily.
The genetic constitution of the individual; the characterization of the genes.
