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 on groEL methodology. 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.
