[Detection of tick and tick-borne pathogen in some ports of Inner Mongolia].
OBJECTIVE
To investigate the distribution, composition and situation of natural infection pathogen of tick species in the main ports of Inner Mongolia.


METHODS
All ticks were collected manually with white cloth, from the grassland and searching for the hosts followed by detection of pathogens, with PCR.


RESULTS
1313 ticks identified, belonged to 1 family, 4 geniuses and 7 species in the three surveyed areas, with Dermacentor nuttallia distributed in the Ceke, Mandula and Manzhouli bordering ports. 69.08% of the total species were discovered at Port Ceke, with Rhipicephalus pumilio as the predominant one, which accounted for 74.86%. 5 kinds of tick-borne disease pathogens were detected from ticks in these three bordering ports while only Coxiella burnetii was found at the Port Ceke. In these three ports, the average infection rates of Lyme disease borrelia, Human babesia microti, Spotted fever group Rickettsia, Coxiella burnetii, Ehrlichiosis were 15.08%, 3.35%, 1.98%, 1.07%, 0.99% respectively. The positive rate of tick infected with Borrelia burgdorferi were 13.56%,22.88%,5.00% in the 3 bordering ports, respectively with significant differences. The positive rates of Babesia microti and Spotted fever group Rickettsia infections were also significantly different among these areas.


CONCLUSIONS
The natural infection rates of the above mentioned five kinds of tick-borne pathogens were different in the Ports Ceke, Mandula and Manzhouli.
