echinococcus granulosus in gray wolves and ungulates in idaho and montana, usa.we evaluated the small intestines of 123 gray wolves (canis lupus) that were collected from idaho, usa (n=63), and montana, usa (n=60), between 2006 and 2008 for the tapeworm echinococcus granulosus. the tapeworm was detected in 39 of 63 wolves (62%) in idaho, usa, and 38 of 60 wolves (63%) in montana, usa. the detection of thousands of tapeworms per wolf was a common finding. in idaho, usa, hydatid cysts, the intermediate form of e. granulosus, were detected in elk (cervus elaphus), mule deer ( ...200919901399
the present situation of echinococcoses in mongolia.this review presents the historical and current situation of echinococcoses in mongolia. since the collapse of the soviet union in 1991, mongolia's health surveillance infrastructure has been very poor, especially as it pertains to chronic diseases, including neglected zoonotic diseases (nzds). although there is anecdotal evidence of people dying from hepatic disease due to infection with the larval stage of echinococcus spp., there are very few published reports. all confirmed cases of echinoco ...201526234999
first detection of echinococcus multilocularis in dogs in a highly endemic area of poland.the aim of the investigation was to estimate the epizootic situation concerning infection by the cestode echinococcus multilocularis leuckart, 1863 in dogs (canis lupus familiaris linnaeus) from a polish region where this parasite is highly prevalent in red foxes. faecal samples (n = 148) were collected from rural dogs in podkarpackie province. samples were examined through nested pcr (for e. multilocularis), multiplex pcr (e. multilocularis, species of taenia linnaeus, 1758) and pcr [e. granulo ...201627311792
taeniid species of the iberian wolf (canis lupus signatus) in portugal with special focus on echinococcus spp.taeniid species represent relevant pathogens in human and animals, circulating between carnivorous definitive hosts and a variety of mammalian intermediate hosts. in portugal, however, little is known about their occurrence and life cycles, especially in wild hosts. an epidemiological survey was conducted to clarify the role of the iberian wolf as a definitive host for taeniid species, including echinococcus spp. wolf fecal samples (n = 68) were collected from two regions in northern portugal. t ...201324533315
protozoan and helminth parasite fauna of free-living croatian wild wolves (canis lupus) analyzed by scat collection.the european wolf (canis lupus) is a large carnivore species present in limited areas of europe with several small populations still being considered as endangered. wolves can be infected by a wide range of protozoan and metazoan parasites with some of them affecting free-living wolf health condition. on this account, an epidemiological survey was conducted to analyze the actual parasite fauna in croatian wild wolves. in total, 400 individual faecal samples were collected during field studies on ...201728043382
the occurrence of taeniids of wolves in liguria (northern italy).canids are definitive hosts of taenia and echinococcus species, which infect a variety of mammals as intermediate or accidental hosts including humans. parasite transmission is based on domestic, semi-domestic and wildlife cycles; however, little is known of the epidemiological significance of wild large definitive hosts such as the wolf. in this study, 179 scats of wolves (canis lupus italicus) collected throughout the italian region of liguria were analyzed for the detection of taeniid infecti ...201526042204
