Sequence analysis of the msp4 gene of Anaplasma ovis strains
Veterinary Microbiology, 2007Anaplasma ovis (Rickettsiales: Anaplasmataceae) is a tick-borne pathogen of sheep, goats and wild ruminants. The genetic diversity of A. ovis strains has not been well characterized due to the lack of sequence information. In this study, we evaluated bighorn sheep (Ovis canadensis) and mule deer (Odocoileus hemionus) from Montana for infection with A ...

Background: Anaplasma ovis is an intra-erythrocytic gram negative rickettsial bacterium that infects small ruminants, resulting in huge economic losses worldwide. Materials and Methods: The present investigation aims at reporting the molecular prevalence

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.

SUMMARY Blood samples from 16 anaplasmosis complement-fixation (cf) positive sheep from a flock near Cambridge, Idaho, were inoculated into 3 intact sheep and 3 splenectomized calves. The 3 sheep became cf positive, and 2 developed parasitemia. None of the 3 calves had signs of anaplasmosis, but all became ill when they were subsequently challenge ...

An Anaplasma centrale genomic library was constructed in pUC13. Two clones pAC5 and pAC137 hybridising to A. centrale and A. marginale DNA were isolated from this library. One of these, pAC5, also hybridised to DNA from A. ovis. The total insert of pAC5 was subcloned into pBR322. This subclone, pAC5-12, could detect 1 ng A.

Infection of Splenectomized Calves with Anaplasma ovis
American Journal of Veterinary Research, 1981SUMMARY An Anaplasma was not recovered from 2 splenectomized calves at 17 days after A ovis inoculation, but was recovered from 1 of the calves at 177 days after inoculation. In a 3rd calf exposed to A ovis, an Anaplasma was recovered at 177 and 262 days after inoculation.

CanAnaplasma ovisin Small Ruminants be Neglected any Longer?
Transboundary and Emerging Diseases, 2013Anaplasma 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.

EXPERIMENTAL INFECTIONS OF ANAPLASMA OVIS IN PRONGHORN ANTELOPE
Journal of Wildlife Diseases, 1987Anaplasma 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.

Anaplasma ovis in sheep: Experimental infection, vertical transmission and colostral immunity
Small Ruminant Research, 2019Ovine anaplasmosis is caused by the obligate intraerythrocytic bacteria Anaplasma ovis and the disease is characterized by anaemia, weight loss and weakness. A severe outbreak of ovine anaplasmosis was diagnosed for the first time in Spain in 2014 and, subsequently, a research was developed in order to increase de knowledge of this not-well-known ...

Molecular detection of Anaplasma ovis in small ruminants and ixodid ticks from Mongolia.
Parasitology International, 2019Anaplasma 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.
