Molecular Detection and Phylogenetic Characterization of spp. in Dogs from Hainan Province/Island, China.

Anaplasmosis is a serious infection which is transmitted by ticks and mosquitos. There are very few reports and studies that have been carried out to understand the prevalence, distribution, and epidemiological profile of spp. infection in dogs in Hainan province/island. In the present study, we have tried to understand the prevalence, distribution, and occurrence of spp. infections in dogs ( = 1051) in Hainan Island/Province to establish a surveillance-based study. The confirmed positive samples by Polymerase chain reaction (PCR) were subjected to capillary sequencing for further strain-specific confirmation, followed by the construction of phylogenetic trees to determine their genetic relations. Various statistical tools were used to analyze related risk factors. There were three species of detected from the Hainan region; namely, , , and . The overall prevalence of is 9.7% (102/1051). was prevalent in 1.0% of dogs (11/1051), was found in 2.7% of dogs (28/1051), and in 6.0% of dogs (63/1051). Our surveillance-based study conducted to understand the occurrence and distribution pattern of spp. in Hainan will help in designing effective control measures along with management strategies so as to treat and control the infection in the area.
