Sixty-seven hog deer (Cervus porcinus) ranged free on one farm in Samuth-prakarn province, Thailand died with nervous signs between September 1997 and February 1998. Most of them presented with nervous signs including: paresis of hind limbs, lateral recumbency, excitation, convulsion and death. Six animals and one carcass were submitted for investigation at the National Institute of Animal Health, Bangkok. Trypanosoma evansi was detected in blood and cerebrospinal fluid of 3 and 4 animals, respectively. Antibodies to T. evansi were found in all hog deer by enzyme-linked immunosorbent assay. Upon histopathological observation there was a generalized nonsuppurative meningo-encephalitis affecting white and gray matter at all levels of the brain. Typically, there were broad perivascular cuffs of mononuclear inflammatory cells including lymphocytes, and some Mott cells. No trypanosomes were found in any tissue examined by conventional histopathology. However, numerous T. evansi were demonstrated by streptavidin-biotin complex technique in neuropils and Virchow-Robin spaces of brain in there animals.
