Abstract:

Objective To investigate the species and distribution of ticks in Tianjin, China, the pathogens carried by the ticks, and the knowledge of self-protection against ticks in local residents, and to provide a basis for the control and prevention of ticks. Methods The specimens of ticks were collected with white cloth from the natural habitat and picked directly from the body surfaces of livestock such as cattle and sheep. The specimens were identified and classified and subjected to detection of carried pathogens, such as Bunia virus, Borrelia burgdorferi, Bartonella, and Anaplasma phagocytophilum. Twenty residents were randomly selected from each district or county of Tianjin and the knowledge of self-protection against ticks was surveyed. Results Ticks were found in 8 districts or counties of Tianjin. A total of 152 ticks were collected and identified, including Ixodes persulcatus (23.03%) and Haemaphysalis longicornis (76.97%). No pathogen was detected from the tick specimens. More than 70% of the surveyed residents had the knowledge of tick bite prevention, and over 80% of the surveyed residents had the knowledge of correct treatment after bite, without significant difference between urban and rural residents. Conclusion There are ticks in Tianjin, and no pathogen is found from the tick specimens. Most residents have the knowledge of self-protection against ticks. More measures should be taken to enhance the control and prevention of tick-related diseases, including spreading tick-related knowledge among residents, improving the ability of health care sector to control and prevent tick-related diseases, and making related emergency plans.
