Tick infestation and tick-borne pathogen infection in human and ticks in a military camp and nearby area in Xiaogan, Hubei
Objective To investigate the prevalence of ticks in a military camp,the tick-borne pathogens infection of ticks and human in Xiaogan,Hubei,to provide scientific proof for prevention and treatment of the tick infestation and tick-borne diseases.Methods A total of 110 of human blood samples were collected,Among them,One were sampled from a police dog breeder in military camp,and the other samples were from the out patients who had unknown fever in a hospital apart from 20 km away.Twety-six ticks were sampled,6 came from the guard dogs and 20 from the camp lawn.Samples were mixed into groups and detected by PCR-mass spectrum methods to check the pathogens and their gene types.Results Three and one out of seven groups of blood from outpatients were detected as positive of Bartonella spp.and Legionella pneumophila,respectively.The minimum infection rates were 27.77‰ and 8.52‰,respectively.Bartonella spp.was detected from the dog breeder blood sample.The ticks from the police dogs and from the camp grassland were detected as positive of Bartonella and Rickettsia,individually.Bartonella genotypes were different among the blood samples from the dog breeder and the patients and the ticks from the police dog.Blood samples contain B.bov/s USAMRIID-000002,B.birtlesii USAMRIID-000020,B.elizabethae USAMRIID-000008 or Bartonella grahamii USAMRIID-000026,Bartonella grahamii USAMRIID-000026,while the ticks sample carry Bartonella vinsonii subsp,berkhoffii genotype Ⅲ.Different Bartonella genotypes were detected from different sample sources.The gene types of Bartonella detected differed from each other.Conclusion In our research area,there were heavy ticks infestation.And the infection rate of tick-borne pathogens in outpatients who had unknown fever was high.Preventive measures should been taken.
