Survey of coyotes, red foxes and wolves from Wyoming, USA, for Echinococcus granulosus s. l.

The paraphyletic group Echinococcus granulosus sensu lato is comprised of parasitic tapeworms of wild and domestic canids such as wolves (Canis lupus) and coyotes (Canis latrans), which serve as definitive hosts, and ungulates, which are the intermediate hosts. Members of this tapeworm group are characterized by both cosmopolitan distribution and zoonotic disease potential. This survey (conducted from 2012 through 2017) was designed to provide insight into the prevalence and distribution of this parasite in wild canids in Wyoming.

LEPTOSPIRA ANTIBODIES DETECTED IN WILDLIFE IN THE USA AND THE US VIRGIN ISLANDS.

From 2011 to 2017, 4,534 serum samples from 13 wildlife species collected across the US and in one territory (US Virgin Islands) were tested for exposure to Leptospira serovars Bratislava, Canicola, Grippotyphosa, Hardjo, Icterohaemorrhagiae, and Pomona. Of 1,759 canids, 1,043 cervids, 23 small Indian mongooses ( Herpestes auropunctatus), 1,704 raccoons ( Procyon lotor), and five striped skunks ( Mephitis mephitis), 27.0, 44.

Surveillance for Baylisascaris procyonis in raccoons (Procyon lotor) from Wyoming, USA.

Baylisascaris procyonis is a common roundworm of raccoons that causes severe clinical disease in many vertebrates, including humans. The distribution of B. procyonis in the US is poorly documented in portions of its range and has not been reported from Wyoming.

Epizootiologic survey of Mycobacterium bovis in wildlife and farm environments in northern Michigan.

Bovine tuberculosis (bovine TB), caused by Mycobacterium bovis, has reemerged in northern Michigan, USA, with detections in white-tailed deer (Odocoileus virginianus) in 1994 and in cattle in 1998. Since then, significant efforts have been directed toward reducing deer densities in the area in the hopes of reducing the bovine TB prevalence rate in deer and eliminating spillover of the disease into cattle. Despite the success of the efforts to reduce deer densities, additional cattle herds have become infected.

Population monitoring in support of a rabies vaccination program for skunks in Arizona.

Three population monitoring methods were evaluated in support of a trap/vaccinate/release program for controlling a bat variant of rabies virus in skunks (Mephitis mephitis) in Flagstaff, Arizona (USA). Skunks were the primary species targeted for population monitoring during the program, but feral cats were also monitored as they represented an abundant secondary vector species capable of rabies transmission. Skunks were vaccinated and released, except for a subset tested for rabies.
