Study on the situation of plague in Junggar Basin of China

objective To understand the distribution, fauna, population structure of host animals and their parasitic fleas as well as popular dynamic of animal plague of natural plague foci in Junggar Basin.Methods Sample materials and data of animals and vector insects were collected using ecological methods and the population structures were analyzed statistically.F1 antibody of Yersinia pesos in rodents''serum and organ suspension was detected by means of IHA while the pathogen of Y.pesos in rodents and vector insects was detected by means of aetiological detections and the isolated Y.pestis was detected using biochemical methods.Results The small mammals which were found in Junggar Basin belonged to 17 species of 11 genera 7 families.Of them, 13 species of rodents were included whose parasitic fleas belonged to 19 species of 10 genera 8 families.The average coverage of Rhombomys opimus hole-community was 22.5 % in Junggar Basin with the average density of R.opimus hole-community was 15.9/hm2 and the average rate of habitat of the hole-community was 70.290.In the R.opimus community, the average density of rodents was 3.1 / hole-community, and 34.4/hm2 in the nature plague foci.In the population structure of the hole-community of R.opimus,R.opimus accounted for 72.9% in the total captured rodents, Meriones meridianus was 24,5 % while the others were 2.6.In the nocturnal community of rodents,Mmeridianus accounted for 64.0% in total captured rodents, Dipus sagitta was I5.1%, M.erythrourns was 7.5%and the others were 13.4 96.In the rodents community of Junggar Basin, the rate of R.opimus with fleas was 84.9%,which was the highest, followed by M.tamariscirtus, Euchoreutes naso and M.erythrourns,with the rates as 71.4%,66.706 and 62.796 respectively: The rate of M.meridianus with fleas was 38.3 }.There were 16 species of parasitic fleas in R.opzmus,with the total flea index as 8.58 and the dominant species was Xenopsylla skrjabini.There were I7 and 16 kinds of fleas in M.erythrourns and M.meridianus respectively with the total flea index were 1.59 and 1.15,with dominant fleas were Nosopsyllus laeviceps and X.skrjabiui.The serum and organ suspension of 3179 rodents which belonged to 12 species were detected by means of IHA, of them 774 samples were p}itive and the positive rate was 5.5%.There were 1356 samples of R.opimus in these materials, and 164 were positive, accounted for 12.1%The samples of Mmeridianus were 1255,with 9 positive, accounted for 0.7%.The samples of D.sagitta were 116 with 1 positive and the rate was 0.9.The samples of other rodents were 452 but were all negative.There were in total 2975 organs collected from rodents, when detected by methods of isolated of Y.pesos.15 strains of Y.pesos were isolated from 1243 R.opimus,and 2 strains isolated from 1230 M.meridianus.A total number of 11 647 fleas from rodents were detected by methods of isolated of Y.pesos in which 1 strain of Y.pesos was isolated from 4713 X.skrjabeni,and 6 were isolated from 2101 Xenopsylla minax,l from 328 Xenopsylla conformis conformis and 1 from 250 Echidnophaga oschanini.Among the other 4255 fleas, none was isolated.The biochemical properties of these Y.pesos which isolated from Junggar Basin were positive of Maltose, Ejiao sugar and Glycerol, and negative of Rhamnose and Nitrogen, which were all strongly poisonous to mouse.Conclusion The natural plague foci in Junggar Basin spread all over the whole Junggar Basin.There were animal plague cases found in 12 counties (cites) while Karamy, Sole, Jimusaer and Qitai were confirmed as plague foci counties(cities).Animals and vector insects of the foci were complicated but the ecological system was stable.R.opimus was recognized as the dominant host animal and its biochemical type belonged to the Middle Ages, suggesting that the foci was a new type of natural plague foci.belonged to the Middle Ages, suggesting that the foci was a new type of natural plague foci.
