7 mar 2024 · Anaplasma ovis (A. ovis) is the predominant causative agent of anaplasmosis in goats and sheep in most tropical and subtropical regions of the world. However, there is considerable variation in reported infection rates, breed susceptibility, and controversial findings regarding the haemolytic effects of A. ovis infection in goats.
anaplasmosis in cattle and wild ruminants, and A. ovis in sheep and goats [6]. The transmission of Anaplasma spp. can be affected both mechanically by biting flies or blood-contaminated fomites and biologically by ticks. The distribution of anaplasmosis may continue to change
A high prevalence of A. ovis DNA detection was found at the individual (52.0%) and flock levels (83.6%) with a within-flock prevalence ranging between 0–100%. Rhipicephalus bursa was the only tick species collected on goats (n = 355) and the detection rate of A. ovis DNA in ticks was 20.3%.
“A capra” infection presented with symptoms that could make diagnosis difficult. A phagocytophilum infection is not often lethal in immunocompetent individuals, but delaying antibiotic treatment can be fatal. 12 Morbidity and mortality associated with “A capra” is not yet known.
3 sty 2019 · 53 Citations. 1 Altmetric. Metrics. Abstract. Background. Anaplasma ovis is a major cause of small ruminant anaplasmosis, a tick-borne disease mainly affecting small ruminants in tropical and subtropical regions of the world.
26 lut 2022 · Our data showed significant effect of breeds on prevalence of anaplasmosis in goats (p = 0.027). Higher infection was recorded in jamnapari (23.52%) followed by crossbreed (22.31%) and black Bengal goats (12.21%), respectively.
One goat (2.5%) tested positive for the presence of A. phagocytophilum genetic material, while the seropositivity rate ranged from 20 to 71%, depending on the surveyed year and area. These results indicate widespread exposure to Anaplasma spp. in the Swedish goat population.
