Epidemiological investigation of common tick-borne protozoan diseases in cattle and camels in some areas of Xinjiang
The purpose of the study was to investigate the pathogens carried by cattle and camel ticks in some experimental areas of Aksu,Altay,Changji,Hami,Hotan,and Yili in Xinjiang.Pathogens(Babesia,Theileria annulata,Rickettsia,Anaplasma)were detected by PCR in 507 blood samples collected from cattle and camels,and phylogenetic analysis was carried out by MAGA11.0 software.The results showed that the total positive rate of Theileria annulata in three regions(Aksu,Altay and Hami)was 9.86%(50/507),among which the positive rate of cattle was 7.81%(19/243)and camel was 11.74%(31/264).Babesia,Rickettsia,and Anaplasia were not detected.Phylogenetic tree showed that the positive samples of Theileria annulata in camel were closely related to Chinese strains(accession number:OM140998),and the similarity was 99.31%.There was a close genetic relationship between the bovine Theileria annulata and Saudi Arabian strain(accession number:OM273908),and the similarity was 99.60%.The infection of tick-borne diseases of cattle and camels in six areas of Xinjiang was investigated,and Thaleria annulata was detected in camels for the first time,which could provide technical support for comprehensive prevention and control of tick-borne diseases of cattle and camels in Xinjiang.
