The wild dog (Lycaon pictus): a new host for Ancylostoma caninum.

Faecal nematode egg counts performed on one captive and 49 free-ranging wild dogs (Lycaon pictus) revealed the presence of eggs of Ancylostoma spp. in 12 (24%) of the animals. The captive wild dog pup showed anorexia, general malaise, pale mucous membranes and black stools. Adult male and female Ancylostoma caninum were recovered from an approximately 3-month-old pup which died of distemper-like disease and a 9-year-old severely debilitated captive wild dog. A single adult A. caninum was also recovered from the intestines of a free-ranging wild dog in the Kruger National Park. These findings confirm the wild dog to be a host for A. caninum.
