Abstract
Ticks and tick-borne diseases pose a growing threat to human and animal health, which has brought great losses to livestock production. With the continuous expansion of human activities and the development of natural resources, there are more and more opportunities for humans to contract ticks and tick-borne pathogens. Therefore, research on ticks and tick-borne diseases is of great significance. This paper reviews recent progress on tick-borne bacterial diseases, viral diseases, and parasitic diseases in China, which provides a theoretical foundation for the research of tick-borne diseases.
Highlights
Ticks are a type of arthropods that are obligately blood-sucking all over the world [1,2]
The results showed that the positive rate of spotted fever group rickettsia (SFGR) was 47.50% (152/320), and there were three genotypes, namely Candidatus Rickettsians Tarasevich (CRT), R. lauticus, and R. heilongjiangensis
The main tick-borne viruses in China include tick-borne Encephalitis virus (TBEV), Crimean–Congo hemorrhagic fever virus (CCHFV), and severe fever with thrombocytopenia syndrome virus (SFTSV), which are mainly distributed in Qinghai, Xinjiang, and other places [73,74,75,76]
Summary
Ticks are a type of arthropods that are obligately blood-sucking all over the world [1,2] They often parasitize on the surface of humans and animals, playing important roles as vectors or intermediates for pathogens including bacteria, viruses, and protozoa [3,4,5]. The detection rate of the Brucella omp gene was 4.6% (16/350) in female ticks and 40.9% (90/220) in larvae, which developed from brucella-positive eggs. Li Y et al collected 750 blood-sucking female ticks in Xinjiang and found that the detection rate of Brucella in the collected ticks was 26.2%, with 96–100% nucleic acid homology to that of the sequences deposited in GenBank [23]. Strengthening the tick eradication work in breeding sites can reduce the risk of transmission of the disease, thereby reducing the incidence of the disease
