Hepatozoonosis in Free-Ranging American Mink (Neovison vison) in Pennsylvania, USA: Case Series.
Abstract: Hepatozoon spp. are protozoal organisms that infect a wide variety of animal hosts. Three free-ranging American mink (Neovison vison) from Pennsylvania, USA, were diagnosed with hepatozoonosis either as the primary cause of mortality or as a co-morbidity with canine distemper virus infection or trauma. In all cases, protozoa were detected in the lungs and/or heart with varying severity, as characteristic microgranulomas with intrahistiocytic merozoites as well as fewer distinct meronts. Partial 18S rRNA gene sequence from one case was identical to a Hepatozoon sp. previously detected in mink followed by a Hepatozoon sp. detected in ticks and other mustelid species. This paper expands on the limited knowledge of Hepatozoon spp. infecting North American mustelids and correlates that a previously detected Hepatozoon sp. in mink can cause histopathologic lesions and occasional mortality.
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.
