Tracking Survey of the First Plagued Site in the Altai Mountains along the Sino-Mongolia Border and the Plague in its Two-Flank Areas
This article tracks the epidemic dynamics of newly plagued sites in the Altai Mountains along the Sino-Mongolia border and the plague in its two-flank areas.Plague tracking and investigation was carried out in the newly plagued sites in the Takshken Altai Mountains along the Sino-Mongolia border,the surrounding new cave groups,the Laoye Temple on the east and west flanks,and the Jimunai Port.Plague testable materials were collected using methods including the bow-shaped trap-on-the-day method and the 5-meter clamp method.Plague pathogens were detected by plague serology,four-step assay and molecular biology methods.The monitoring results are as follows:2,660 traps were placed at the monitoring sites in the three port areas,and 104 rodents of 11 species,11 genera,and 7 families were captured,with a capture rate of 3.91%.Among them,1,760 traps were placed in the newly plagued sites in Takshken Port Area and the Altai Mountains,and 78 animals were captured,with a capture rate of 4.43%.9 plague F1 antibodies were detected in 7 Citellus undulatus and 2 Mustela putorius in 3 new cave groups in the new epidemic sites and their surroundings,with a positive rate of 11.54%,and 5 newly infected rat holes were found,with a plague infection rate of 0.97%.The total flea infection rate and total flea index of rodents in the three ports were 52.88%and 2.82.The above results show that in 2023,plague F1 antibodies were detected once again from Citellus undulatus and Mustela putorius in the first plagued site and surrounding areas in the Altai Mountains along the Sino-Mongolia border.And in these newly plagued sites and surrounding areas,the plague is still active.
