dc.description.abstract | Trichinella zimbabwensis has been found naturally infecting crocodiles (Crocodylus niloticus) in Zimbabwe, Mozambique, Ethiopia and South Africa, as well as monitor lizards (Varanus niloticus) in Zimbabwe. The reports on natural infections were mostly accidental rather than structured surveys and involved very few animals. Previous surveillance studies in South Africa reported a 38.5% prevalence of T. zimbabwensis among wild crocodiles tested from the Mpumalanga province and Kruger National Park (KNP). No studies have been conducted to date on the geographical distribution and occurrence of T. zimbabwensis in wild crocodiles and varans in countries in southern Africa. Recent outbreaks of pansteatitis in crocodile populations of the KNP, South Africa, provided an opportunity to conduct a more structured survey aimed at elucidating the occurrence and distribution of T. zimbabwensis in culled wild crocodile populations within the KNP. Results from this study showed that T. zimbabwensis occurred in 10 out of 12 culled crocodiles form the KNP. The results also showed that the natural distribution of T. zimbabwensis in crocodiles includes all the major river systems in the KNP. The predilection sites of larvae in muscles followed a different pattern in naturally infected crocodiles compared to observations in experimentally infected mammalian hosts. | en |

dc.description.sponsorship | The authors wish to thank the rangers and scientific services staff of KNP responsible for the capture, euthanasia and transport of crocodiles. Our sincere thanks for the assistance received from the state veterinarian, Nelspruit, with the collection of samples; Dr Huchzermeyer for his assistance with necropsies; the invaluable insight into crocodilian anatomy and physiology provided by Drs Huchzermeyer, Webb, Manolis and Richardson; to Mrs T. La Grange, staff and students of the School for Biological and Conservation Sciences of the University of KwaZulu-Natal for their assistance in testing of samples; the International Trichinella Reference Centre for species confirmation; and Mr F.
