title: Experimental infection of white-tailed deer with Elaeophora schneideri.
abstract: An attempt was made to infect fawn and adult white-tailed deer, Odocoileus virginianus, with Elaeophora schneideri. Experimental infection of fawns caused a relative eosinophilia that persisted. Obstruction of a coronary artery caused death of one fawn, and weakness, dyspnea, and locomotor difficulties were observed in another fawn and an adult. Plaque-like lesions were observed grossly in the intimal lining of carotid arteries, and subintimal thickening and proliferation of fibrous tissue in vessel walls were observed microscopically. Nematodes were recovered from 3 of 4 fawns and 0 of 4 adults, suggesting an age-related resistance in older animals. Microfilariae were recovered via facial skin biopsy of a single fawn. This study suggests that white-tailed deer serve as usual hosts for E. schneideri, although the host-parasite relationship may be tenuous.
