Abstract:
To explore pathogens in several tick species in endemic areas of Shandong province,unfed ticks and parasitic ones were collected in seven areas of Shandong province during 2021-2022 and morphologically identified.Five common tick-borne pathogens were detected by PCR with universal primers on the tick samples and phylogenetic analysis based on the sequences from positive pathogens were also performed as well.The results showed that the collected tick samples included 2 genera and 4 species,respectively comprising 145 of Haemaphysalis longicornis,2of Hae.concinna,2of Hae.campanulate,and 5 of Rhipicephalus sanguineus.A total of 34 collected ticks were found with spotted fever group Rickettsia infection,with a total positive rate of 22.08%,29 samples carried Anaplasma,with a total infection rate of 18.83%,the total infection rate of Theileria and Borrelia burgdorferi were revealed as 5.84% and 0.65%,respectively,and no positive samples were detected for Borrelia recurrentis.In conclusion,Hae.longicornis was shown as the dominant tick species in the sampling areas in Shandong province,and various pathogens were found harbored in different tick species.Local surveillance and awareness of tick-borne diseases should be strengthened for the purpose of efficient prevention and control measures.
