EXPERIMENTAL INFECTIONS OF ANAPLASMA OVIS IN PRONGHORN ANTELOPE

Journal of Wildlife Diseases, 1987
Anaplasma ovis was experimentally transmitted from sheep to pronghorn antelope (Antilocapra americana) and back to sheep. Anaplasma ovis was recovered in splenectomized sheep, from two of three spleen-intact pronghorns following their inoculation with blood from known A. ovis carrier sheep. These two pronghorns exhibited a 0.5% or higher A.

Chemoprophylaxis of Anaplasma ovis infection in sheep with a long-acting oxytetracycline

Veterinary Parasitology, 1985
The chemoprophylactic efficacy of long-acting oxytetracycline was determined in 13 susceptible ewes infected with Anaplasma ovis. The drug was administered intramuscularly at a dose rate of 20 mg kg-1 body weight during the prepatent period. When the ewes were exposed to an equivalent homologous challenge on Day 45 post-infection, each showed a mild or

SUSCEPTIBILITY OF ELK (CERVUS ELAPHUS) TO EXPERIMENTAL INFECTION WITH ANAPLASMA MARGINALE AND A. OVIS

Journal of Wildlife Diseases, 1996
Anaplasma ovis was experimentally transmitted from domestic sheep to elk (Cervus elaphus) and back to splenectomized sheep. No rickettsemias were detected but serum from three of seven experimentally inoculated elk developed Anaplasma spp.-reactive antibody as measured by indirect immunofluorescence (IIF) or by the rapid card agglutination and ...

First detection of Anaplasma ovis in sheep and Anaplasma platys-like variants from cattle in Menoufia governorate, Egypt

Parasitology International, 2020
Tick-borne diseases are of global economic importance, especially due to the costs associated with disease treatment and productivity losses in livestock. In this study, 244 livestock animals (cattle N = 92, buffaloes N = 86 and sheep N = 66) from Menoufia, Egypt were tested for Anaplasma, Ehrlichia and Babesia species using PCR.

CanAnaplasma ovisin Small Ruminants be Neglected any Longer?

Transboundary and Emerging Diseases, 2013
Anaplasma species are obligate intracellular rickettsial pathogens transmitted by ticks with an impact on human and animal health. Anaplasma ovis infects sheep and goats in many regions of the world, and it can be diagnosed by different methods like Giemsa staining, PCR or competitive ELISA.

Effect of chemotherapy on semen characteristics of Balami rams infected with Anaplasma ovis

Veterinary Research Communications, 1988
Six intact Balami rams were experimentally infected with Anaplasma ovis. Another six were infected one month after splenectomy and six others served as controls. Clinical manifestations of the disease, first observed between 5 to 7 days post-infection, were more severe and prolonged in the splenectomised-infected than in the intact-infected group ...

Validation of an Anaplasma marginale cELISA for use in the diagnosis of A. ovis infections in domestic sheep and Anaplasma spp. in wild ungulates

Veterinary Microbiology, 2008
A commercially available (cELISA) kit for diagnosing Anaplasma marginale infection in cattle was validated for diagnosing A ovis infection in sheep using the bovine serum controls as supplied by the manufacturer (BcELISA) and sheep serum controls from pathogen-free sheep (OcELISA). True positives were identified using two previously established assays,

CHARACTERIZATION OF AN ANAPLASMA OVIS ISOLATE FROM DESERT BIGHORN SHEEP IN SOUTHERN CALIFORNIA

Journal of Wildlife Diseases, 1993
To understand the role of bighorn sheep (Ovis canadensis) in the epidemiology of anaplasmosis, we recovered a field isolate from a suspected enzootic area in southern California (USA). Whole blood was collected from three desert bighorn sheep (Ovis canadensis nelsoni) and inoculated into a susceptible splenectomized domestic sheep, calf and a ...

Molecular detection of Anaplasma ovis in small ruminants and ixodid ticks from Mongolia

Parasitology International, 2019
Anaplasma ovis is a tick-borne obligate intracellular rickettsial bacterium that causes anaplasmosis in domestic and wild small ruminants. Sheep and goats, whose combined population is approximately 48.5-million in Mongolia, play a vital role in the country's economy. In this study, we conducted an epidemiological survey of A.

High genetic diversity of Anaplasma ovis in sheep from Bosnia and Herzegovina

Molecular Biology Reports
Ovine anaplasmosis (sensu stricto) is a rickettsial blood disease caused by the tick-borne species Anaplasma ovis. The disease is characterized by mild anemia, fever, and icterus. A more severe clinical presentation is possible in non-endemic areas. There is no existing data on the presence of Anaplasma ovis in Bosnia and Herzegovina.
