BACKGROUND Certain salivary proteins of phlebotomine sand flies injected into the host skin during blood-feeding are highly antigenic and elicit strong antibody-mediated immune responses in repeatedly-exposed hosts. These antibodies can be measured by enzyme-linked immuno sorbent assays (ELISAs) using salivary gland homogenates (SGHs) as the source of antigens and serve as a markers for exposur...

ticks and tick-borne diseases, including theileriosis, constitute a major constraint to livestock production. two species, known as theileria lestoquardi and theileria ovis, are suspected to contribute to ovine theileriosis in iran. however, the epidemiological aspects of ovine theileriosis are poorly understood in this country. in a survey, designed to identify theileria species in sheep, 52 (...

background: the present study was carried out to investigate the accurate status of ovine theileria infection in sheep from ahvaz and surrounding region, a tropical area southwest iran. methods: a pcr-rflp method based on 18s ribosomal rna gene was designed which could detect and differentiate theileria and babesia spp. and also differentiate main theileria species in sheep at the same time. 11...

UHAZY, L. S., and J. C. HOLMES. 1971. Helminths of the Rocky Mountain bighorn sheep in Western Canada. Can. J. Zool. 49: 507-512. Thirty-six Rocky Mountain bighorn sheep (Ovis c. canadensis), 33 from four areas in Alberta and 3 from Kootenay National Park, British Columbia, were examined for helminths. Data from these exammations were supplemented by examination of 462 fecal samples from the sa...

BACKGROUND Anaplasmosis is an important issue for animal breeders in terms of economic losses as well as a health concern to human. Ticks are considered as the main vector of this disease. Lack of documented information about Anaplasma species in Iran was the scope of this study to determine the population of ticks and the presence of Anaplasma in ticks, domestic ruminants and also human beings...

Excretory-secretory products (ESP) of myiasis producing agents are involved in nutrition and development of larvae and are often immunogens. This study was carried out in order to define the antigenicity, the immunogenicity of Oestrus ovis ESP and the role of sheep immune response to ESP. Twenty-four six to eight month old female lambs were randomly allocated into two groups. The first one was ...

Brucella spp. are Gram-negative bacteria that behave as facultative intracellular parasites of a variety of mammals. This genus includes smooth (S) and rough (R) species that carry S and R lipopolysaccharides (LPS), respectively. S-LPS is a virulence factor, and mutants affected in the S-LPS O-polysaccharide (R mutants), core oligosaccharide or both show attenuation. However, B. ovis is natural...

Two variants of an organism resembling the ovine hemoplasma, Mycoplasma ovis, were detected by PCR in blood samples from a veterinarian in Texas. Coinfection with similar variants has been described in sheep. This represents the first report of human infection with this organism. The veterinarian was coinfected with Bartonella henselae.

Two ruminant acute phase proteins (APPs), haptoglobin (Hp) and serum amyloid A (SAA), were evaluated as serum biomarkers (BMs) for sheep scab-a highly contagious ectoparasitic disease caused by the mite Psoroptes ovis, which is a major welfare and production threat worldwide. The levels of both APPs increased in serum following experimental infestation of sheep with P. ovis, becoming statistica...
