Abstract
Abstract: Neospora caninum is an obligate intracellular protozoan parasite that causes hind-limb paralysis in dogs and abortions in cattle. Recurrent storms of abortions in cattle in Australia are estimated to cause an economic loss of AU$100 million each year, but the source of infection in cattle (i.e., via wild or domestic definitive hosts) remains to be established. We aimed to determine potential sources of horizontal transmission of N. caninum after recent evidence that wild dogs (Canis familiaris) shed N. caninum oocysts in Victoria, Australia. To determine infection levels among wild dogs, samples were collected from three sites in Victoria (n=52) in areas of high wild dog population density (Mansfield, Swifts Creek, and Tallangatta), and N. caninum detection was determined by PCR analysis of blood and duodenal samples. Based on the PCR assay of combined duodenal samples (flotation of duodenal content and just duodenal content), this study detected N. caninum in the fecal material of 11% of wild dogs in Mansfield and 21% of wild dogs in Swifts Creek. This study provides further insight into the possible role of wild dogs as a reservoir of N. caninum in Victoria.
期刊介绍:
The JWD publishes reports of wildlife disease investigations, research papers, brief research notes, case and epizootic reports, review articles, and book reviews. The JWD publishes the results of original research and observations dealing with all aspects of infectious, parasitic, toxic, nutritional, physiologic, developmental and neoplastic diseases, environmental contamination, and other factors impinging on the health and survival of free-living or occasionally captive populations of wild animals, including fish, amphibians, reptiles, birds, and mammals. Papers on zoonoses involving wildlife and on chemical immobilization of wild animals are also published. Manuscripts dealing with surveys and case reports may be published in the Journal provided that they contain significant new information or have significance for better understanding health and disease in wild populations. Authors are encouraged to address the wildlife management implications of their studies, where appropriate.
