Abstract

Necropsy of a chronically lame 16-year-old thoroughbred gelding revealed granulomatous osteomyelitis and polyarthritis due to a widely disseminated infection by Micronema deletrix. Diagnosis was based upon the nematode's morphology with its characteristic rhabditiform oesophagus. Granulomata, often containing one or more centrally located M. deletrix, were observed histologically in sections prepared from femur, kidney, stomach, lung, adrenal gland and sublumbar lymph nodes. Neither verminous meningo-encephalitis nor cephalic granulomata, which are the more commonly described lesions, was found.

    The predominant inflammatory cells are plasmocytes and lymphocytes, occasional eosinophils and numerous macrophages, giant cells and epithelioid cells (Rames et al., 1995). Similar inflammation was observed, in systemic infections, in the kidneys (Isaza et al., 2000; Kinde et al., 2000), lymph nodes, uterus and heart (Isaza et al., 2000), testicles (Kinde et al., 2000), stomach, lungs, joints, adrenal gland (Simpson et al., 1988), prepuce (Dunn et al., 1993), bones (Kreuder et al., 1996; Teifke et al., 1998) and the spinal cord, the roots of the peripheral nerves and the cauda equina (Johnson et al., 2001). The predominant localization of the rhabditiform larvae is perivascular.
