Occurrence of avian Schistosomatidae (Trematoda) in South African birds as determined by a faecal survey

Abstract

The abundance, prevalence and distribution of avian Schistosomatidae in South African birds has been estimated by means of a survey for parasite eggs in faecal samples. Eight types of eggs were recovered, mostly from members of the Anatidae and Laridae and these have been assigned to the following schistosome genera: Austrobilharzia (1), Gigantobilharzia (1), Trichobilharzia (5) and Ornithobilharzia (1).
