Abstract: | Trichinella murrelli infection was diagnosed in a naturally infected Beagle bitch from VA, USA, where encapsulated larvae were found in histological sections of several skeletal muscles. A laboratory reared dog fed infected muscles resulted in viable muscle larvae that were subsequently infective to Swiss-Webster mice. Multiplex PCR using larvae from the experimentally infected dog demonstrated two distinct bands migrating at 127 bp and 316 bp which together are diagnostic for T. murrelli; the isolate was assigned the ISS code: ISS1608 by the International Trichinella Reference Centre. This is the first report of T. murrelli infection in a companion animal. |
