Tick-Borne Hemoparasites of Sheep: A Molecular Research in Turkey

Pathogens, 2021
Tick-borne diseases (TBDs) indulge in severe economic losses in the livestock industry by adversely affecting the small ruminant breeding in tropical and subtropical zone countries, including Turkey.

Identification of Anaplasma spp. in Tian Shan wapiti deer (Cervus elaphus songaricus) in Xinjiang, China

International Journal for Parasitology: Parasites and Wildlife, 2021
Anaplasma spp. are important zoonotic tick-borne pathogens that impact on human health. There are few reports on the prevalence and molecular genetic characteristics of Cervidae species in China.

A Multiplex PCR Detection Assay for the Identification of Clinically Relevant Anaplasma Species in Field Blood Samples

Frontiers in Microbiology, 2020
The genus Anaplasma (Rickettsiales: Anaplasmataceae), which includes the species Anaplasma capra, Anaplasma bovis, Anaplasma ovis, and Anaplasma phagocytophilum, is responsible for a wide variety of infections in both human and veterinary health ...

Molecular Detection of Novel Genetic Variants Associated to Anaplasma Ovis Among Dromedary Camels in Iran [PDF]

Archives of Razi Institute, 2018
To the best of our knowledge, little information is available regarding the presence of Anaplasma species in camels in Iran. This study sought to investigate the presence of Anaplasma species by microscopy and polymerase chain reaction (PCR) assays in ...

Anaplasma marginale major surface protein 2 CD4+-T-cell epitopes are evenly distributed in conserved and hypervariable regions (HVR), whereas linear B-cell epitopes are predominantly located in the HVR [PDF]

, 2004
Organisms in the genus Anaplasma express an immunodominant major surface protein 2 (MSP2), composed of a central hypervariable region (HVR) flanked by highly conserved regions.

Molecular detection and genetic characterisation of pathogenic Theileria, Anaplasma and Ehrlichia species among apparently healthy sheep in central and western Kenya

Onderstepoort Journal of Veterinary Research, 2019
Tick-borne diseases (TBDs) caused by Theileria, Babesia, Anaplasma and Ehrlichia species are common in tropical and subtropical regions. In this study, we investigated the presence and genetic diversity of Theileria spp., Anaplasma ovis, B.

Rapid and long-term disappearance of CD4+ T lymphocyte responses specific for Anaplasma marginale major surface protein-2 (MSP2) in MSP2 vaccinates following challenge with live A. marginale [PDF]

, 2005
In humans and ruminants infected with Anaplasma, the major surface protein 2 (MSP2) is immunodominant. Numerous CD4(+) T cell epitopes in the hypervariable and conserved regions of MSP2 contribute to this immunodominance.

Detection of Multiple Microorganisms in Ruminant Ticks in Senegal Using High-Throughput Microfluidic Real-Time PCR. [PDF]

Transbound Emerg Dis
Ticks are major vectors of numerous pathogens affecting both livestock and humans. In Senegal, data on the diversity of tick‐borne pathogens (TBPs) in ruminant‐associated ticks remain limited. In total, 1703 ticks were collected from goats, sheep, and cattle across three ecological zones of Senegal (Sudanian, Sahelian, and Sudano‐Sahelian).

Molecular investigation of bacterial and protozoal pathogens in ticks collected from different hosts in Turkey

Parasites & Vectors, 2021
Background The emergence of tick-borne disease is increasing because of the effects of the temperature rise driven by global warming. In Turkey, 19 pathogens transmitted by ticks to humans and animals have been reported.

Molecular prevalence and associated infection risk factors of tick-borne protozoan and rickettsial blood pathogens in small ruminants

BMC Veterinary Research, 2023
Background Tick-borne blood pathogens cause highly pathogenic diseases, which are associated with substantial economic losses in ruminants. Despite this, epidemiological research on these pathogens remains neglected in many countries.
