Anaplasma species are obligate intracellular pathogens that can cause tick-borne diseases in mammalian hosts. To date, very few studies of their occurrence in Korean native goats (Capra aegagrus hircus) have been reported. In the present study, we investigated Anaplasma infection of Korean native goats on Jeju Island, Republic of Korea, and performed phylogenetic analysis based on the 16S rRNA gene sequences. Our results showed that Anaplasma infection was found mostly in adult female goats. The phylogenetic tree revealed that the 7 sequences identified in Korean native goats could belong to Anaplasma sp. and were distinct from A. marginale, A. centrale, and A. ovis. The results indicated that the sequences identified to belong to Anaplasma were closely related to sequences isolated from goats in China and were clustered within the same group. To our knowledge, this is the first study to detect Anaplasma sp. infection in Korean native goats.

This study examined the occurrence of Anaplasma spp. and hemoplasma infection in leopard cats, Prionailurus bengalensis euptilurus, in Korea. Twenty-nine biological samples were tested by molecular analysis. Two (6.9%) and eight (27.6%) tested specimens were positive for Anaplasma bovis and hemoplasma infection, respectively. Based on our results, Anaplasma/Ehrlichia spp. and hemoplasma are regularly infecting leopard cat populations of Korea. Considering their endangered status, regular monitoring of infection by arthropod-borne pathogens known to cause clinical symptoms in feline hosts such as Anaplasma/Ehrlichia spp. and hemoplasma would be crucial as part of ongoing conservation efforts.
