Possible factors influencing distribution and prevalence of Echinococcus granulosus in Utah.

Abstract A descriptive epidemiologic study was designed to test an impression that infections of Echinococcus granulosus in dogs, sheep, and human beings were concentrated in central Utah, and to determine when and how the parasite was introduced into the state, which factors were involved in the distribution of the cestode, and which factors increased either […]

Echinococcosis in the Ukrainian SSR

Abstract Various types of echinococcosis foci were detected in the Ukrainian Soviet Socialist Republic: steppe zone foci with sheep pattern circulation dominating, where invasion is transmitted according to scheme: sheep–dogs attached to flocks; forest lowland and forest-steppe zones with pig pattern of echinococcosis circulating, where invasion is transmitted according to scheme: pigs–dogs. In steppe zone […]

Human echinococcosis in Bulgaria: a comparative epidemiological analysis.

Abstract The present article describes the importance of human echinococcosis as a public health problem in Bulgaria, outlines the control measures carried out and evaluates comparatively the situation over three periods spanning 46 years (1950-1995). During the first period (1950-62), a total of 6469 new surgically confirmed cases of hydatid disease were recorded in Bulgaria, […]

Wolves in Colville Valley worry state wildlife managers

*Staff Note* – Apparently missing from this information are two important facts. One, that dogs and wolves mixing this readily is a sure recipe for cross breeding between dogs and wolves – a sure destruction of the wolf gene. Second, wolves are carriers of disease, specifically Echinococcus granulosus worms, Neospora Caninum, and others. Wolves inhabiting […]

Intestinal parasites of wolves (Canis lupus L. 1758) in northern and western Canada

ABSTRACT Gray wolves (Canis lupus L., 1758) are mobile opportunistic predators that can be infected by a wide range of parasites, with many acquired via predator-prey relationships. Historically, many of these parasites were identified only to genus or family, but genetic tools now enable identification of parasite fauna to species and beyond. We examined 191 […]

The occurrence of nematodes of the genus Trichinella in wolves (Canis lupus) from the Bieszczady Mountains and Augustowska Forest in Poland

Abstract The aim of the present study was to investigate the prevalence of Trichinella infection in wolves (Canis lupus) in two regions in Poland. Muscle samples were collected from 21 wolves between 1999 and 2015 and processed by artificial digestion. In two cases, the muscle larvae (ML) were obtained and stored in alcohol. ML were […]

Parasite species of the endangered Iberian wolf (Canis lupus signatus) and a sympatric widespread carnivore

Abstract Parasites have a profound impact on wildlife population dynamics. However, until some years ago, studies on the occurrence and prevalence of wildlife parasites were neglected comparatively with the studies on humans and domestic animals. In this study, we determined the parasite prevalence of two sympatric wild canids: the endangered Iberian wolf (Canis lupus signatus) […]

Description and life-cycle of Taenia lynciscapreoli sp. n. (Cestoda, Cyclophyllidea)

Abstract A new species of tapeworm, Taenia lynciscapreoli sp. n. (Cestoda, Cyclophyllidea), is described from the Eurasian lynx (Lynx lynx), the main definitive host, and the roe deer (Capreolus capreolus and C.pygargus), the main intermediate hosts, from Finland and Russia (Siberia and the Russian Far East). The new species was found once also in the […]

Sarcocystis arctica (Apicomplexa: Sarcocystidae): ultrastructural description and its new host record, the Alaskan wolf (Canis lupus)

Abstract Sarcocystis sarcocysts are common in muscles of herbivores but are rare in muscles of carnivores. Here, we report sarcocysts in the muscles of a gray wolf (Canis lupus) from Alaska, USA, for the first time. Sarcocysts extracted from the tongue of the wolf were up to 900 μm long and slender and appeared to have […]

Echinococcus multilocularis in North America: the great unknown

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains […]
