Libyostrongylus infections in ostriches--a brief review with particular reference to their detection in New Zealand.

Following the recent discovery of Libyostrongylus douglassii in ostriches in New Zealand, information relating to this nematode is reviewed. Amongst some of the topics considered are the parasite's distribution and prevalence, its life cycle and survival, and its diagnosis and control. Of particular interest from a New Zealand perspective is the potential for the parasite to infect other ratites, especially the kiwi. While the current evidence suggests that this may be unlikely to occur, the possibility that it might be able to do so cannot be ruled out entirely.
