Seroprevalence of Toxoplasma gondii in domestic sheep in Belgium
Veterinary Parasitology, 2014Even though infected sheep are a potential source of Toxoplasma gondii infection in humans, information is lacking concerning the seroprevalence of T. gondii infection in sheep in Belgium. We examined 3170 serum samples for anti-Toxoplasma IgG in sheep by total lysate antigen (TLA) enzyme-linked immunosorbent assay (ELISA). IgG to T.

Chromosomes, Hemoglobins, and Transferrins of Iranian Domestic Sheep
Journal of Heredity, 1976Twelve breeds of Iranian domestic sheep were cytogenetically analyzed. The diploid chromosome number of 2n = 54 is identical to that of most breeds of domestic sheep, which is comprised of 3 pairs of metacentric and 23 pairs of acrocentric autosomes. The sex chromosomes consist of a large acrocentric X and a small bi-armed Y.

A New Species of Coccidia from Domestic Sheep
The Journal of Parasitology, 1952While engaged in research on members of the genus Eimeria infecting Wyoming sheep, an undescribed species was observed. The parasite was recovered from two of nine animals housed at the Wyoming State Veterinary Laboratory at Laramie, Wyoming. Both animals had multiple infections; oocysts of Eimeria airloingi, E. ah-sa-ta, E. parva, E.

Mannheimia haemolytica infection in bighorn sheep and domestic sheep
2010Respiratory disease caused by bacteria including Mannheimia haemolytica has contributed significantly to the drastic decline of bighorn sheep (BHS, Ovis canadensis) population of North America, from an estimated two million animals at the beginning of the nineteenth century to less than 70,000 today. Although M. haemolytica causes pneumonia in a number

Retinal Photoreceptor Fine Structure in the Domestic Sheep
Cells Tissues Organs, 1983The structure of the photoreceptors of the domestic sheep has been investigated by light and electron microscopy. In the sheep retina the photoreceptors are readily differentiated and adequately described by the classical terminology of rods and cones. Rods are more numerous then cones. They appear as tall slender cells measuring 45–50 µm in length and

[Domestication-related behavior in sheep].
Genetika, 1997The motivational nature of domestication-related behavior, as well as its formation and variation at the ontogenetic, population, and breed levels were studied. Food motivation participated in the environmental regulation of sheep defensive reactions to humans: an increase in motivation decreased the strength of defensive behavior, and vice versa ...
