Abstract
Anaplasma phagocytophilum is a zoonotic agent of public health importance, infecting both humans and animals. An investigation of the presence of Anaplasma phagocytophilum as well as Anaplasma platys was conducted in a forest area of Selenge province, Mongolia, where ticks are widely distributed and tick-borne diseases are highly endemic. Ticks were collected and tested using polymerase chain reaction based ongroELmethodology. Anaplasma phagocytophilum was detected in 14 (6%) of Ixodes persulcatus ticks and four (1%) Dermacentor nuttalli ticks; infection of Anaplasma platys was detected in 1% of Ixodes persulcatus ticks and 10% of Dermacentor nuttalli ticks. The phylogenetic tree showed that the Anaplasma phagocytophilum clustered with the Russian group, most likely due to similar geographical locations. This finding is significant for both veterinary and public health officials given that these agents can cause both animal and human illness.
Highlights
Anaplasma phagocytophilum is a gramnegative obligate intracellular bacterium long recognized as a veterinary agent[1] and more recently as a human infection
14 (6.3%) Ixodes persulcatus samples and four (20%) Dermacentor nuttalli samples were positive for Anaplasma phagocytophilum; four (1.8%) Ixodes persulcatus samples and two (10%) Dermacentor nuttalli samples were positive for Anaplasma platys (Table 1)
Both Anaplasma phagocytophilum and Anaplasma platys infection were detected in ticks from the forest area of Selenge province, Mongolia
Summary
Anaplasma phagocytophilum is a gramnegative obligate intracellular bacterium long recognized as a veterinary agent[1] and more recently as a human infection. In Mongolia, livestock play an important role as reservoirs of Anaplasma phagocytophilum in endemic areas. The first study on human seroprevalence against Anaplasma phagocytophilum for central Asia reported a seroprevalence of 2.3% in Selenge province, 5.6% in Bulgan province, 2.8% in Dornogov province and 3.0% in both Tov province and Ulaanbaatar.[6]. The objective of this study was to investigate the presence of Anaplasma phagocytophilumin tick vectors in a forest area of Selenge province, Mongolia
