Abstract:
Objective To summarize and analyze the epidemic situation and trend of animal plague in plague foci of Gansu section of Golmud-Dunhuang railway,and provide basic reference for prevention and control of the plague.Methods The quantity of Marmot,rate of carrying fleas and flea index,plague serological and etiology detection results,the cross analyzing results of the railway section and the animal plague foci in Gansu section of Dolmud-Dunhuang railway (Akesai and Subei counties) from 2010 to 2015 were analyzed via the retrospective analysis method.Results The total average density of Marmot of Golmud-Dunhuang railway crossing area Akesai and Subei counties was between 0.23-0.41 per hectare between 2010 and 2015.The rate of parasitic dye fleas in plague foci of Akesai was between 11.30％ and 32.65％,body flea index was 0.74-1.84.The rate of parasitic fleas dye fleas in plague foci of Subei was between 5.34％ and 14.07％,the flea index was 0.25-2.04.The etiology detection Marmot plague of Akesai and Subei was 2 049,142 of them were positive,the positive rate was 6.93％;592 groups of vector were detected,44 of them were positive;the positive rate was 7.43％.There was no statistically significant difference between inspection bacteria rate and parasitic vector inspection rate of Marmot (x2 =0.014,P ＞ 0.05).Totally 1 719 serums of Marmot were tested,132 of them were positive,the positive rate was 7.68％.Totally 421 serums of Canis lupus familiaris were detected,61 of them were positive,the positive rate was 14.49％.There was statistically significant difference between the serum positive rate of Marmot and Canis lupus familiaris (x2 =19.116,P ＜ 0.05).Totally 17 animal foci were found along the railway in 2013,the nearest distance of the foci of bid from construction was 0.5 km,popular area was 61.02 km2,and 1 360 people were directly threatened.Conclusions Animal plague in Akesai and Subei regions along Golmud-Dunhuang railway is highly active.So we must take effective measures to guarantee the smooth progress of railway construction.
