BACKGROUND Coxiella burnetii is a zoonotic bacterium that infects a wide range of animal species and causes the disease Q fever. Both wild and domestic ruminants may be relevant in the epidemiology of C. burnetii infection. In order to investigate the significance of the ruminant host community in the alpine and subalpine ecosystems of the Eastern Pyrenees, Northeastern Spain, in the epidemiolo...

Context Livestock depredation is a major medium- and large-carnivore conservation challenge around the globe, causing substantial economic loss to small-scale agricultural communities in Wolaita Highlands, southern Ethiopia, often leading retaliatory killing. In livestock rates are increasing because of conversion wild habitats into grazing lands. Various studies have examined interactions betw...

We compared the magnitude and duration of fecal shedding of wild-type Escherichia coli O157:H7 to that of an isogenic intimin mutant in young adult cattle and sheep. In both ruminant species, wild-type E. coli O157:H7 was shed in greater numbers and for a longer duration than was the intimin mutant.

A family of endogenous retroviruses (enJSRV) closely related to Jaagsiekte sheep retrovirus (JSRV) is ubiquitous in domestic and wild sheep and goats. Southern blot hybridization studies indicate that there is little active replication or movement of the enJSRV proviruses in these species. Two approaches were used to investigate the distribution of proviral loci in the sheep genome. Fluorescenc...

In this study, POU1F1 gene polymorphism was detected in five sheep populations (large-tailed Han, small-tailed Han, Yuxi fat-tailed, Lanzhou large-tailed, and Mongolian sheep), using DNA pooling and sequencing, to provide theoretical basis for the breeding of excellent sheep varieties. Three single-nucleotide polymorphism (SNP) loci of POU1F1 gene were detected in five sheep populations, namely...

Although controversy surrounds cloning efforts, the cloning of animals to assist efforts to preserve genetic variation in support of endangered species conservation efforts has attracted serious interest. A recent report by Loi et al. describing the cloning of a mouflon (a species of wild sheep) in a domestic sheep surrogate points to potential conservation opportunities and additional challeng...

The Hustain Nuru region of Mongolia’s Chentai Mountains is one of the country’s most pristine wild areas. Valleys and slopes harbour steppe vegetation such as fescue, brome grass and feathergrasses, while birch woods grow in the upper elevations of this relatively low lying mountainous region. A diverse range of wild fauna including marmots, lemmings, red deer, wild sheep, polecats, Pallas cat,...
