新疆霍城县西部荒漠鼠疫自然疫源地调查报告

1983年和1984年4～5月期间,对新疆霍城县西部荒漠进行了调查:共捕获啮齿动物11种544只,其中大沙鼠和子午沙鼠是调查区啮齿类的优势种。前者密度为每公顷1.52只,后者的捕获率为3.3％;集蚤11种7365只,臀突客蚤是上述两种沙鼠的主要寄生蚤;以鼠疫间接血凝试验方法共检验7种动物血清416份,结果皆为阴性。大沙鼠和子午沙鼠虽属区内优势种群,但其分布面积较小、不均匀、密度较低。初步认为,调查区内不会存在鼠疫疫源地。

REPORT ON THE SURVEY OF NATURAL PLAGUE FOCI IN THE DESERT AREA IN WESTERN HUOCHENG COUNTY, XINJIANG

Surveys were made in the desert area in western Huocheng during April and May, 1984. Five hundred and four rodents of 11 species were captured with Rhombomys opimus and Meriones meridianus as dominant species. The population density of the former was 1.52 per hectare and the capture rate of the latter was 3.3%. Among the 7365 fleas of 11 species collected, Xenopsylla minax is the main flea species parasitized on the sand mice. Indirect hemagglutination test was used in the examination of 416 serum spcimens from 7 species of rodents, all showed negative results.Though Rhombomys opimus and Meriones meridianus are the dominant species in the area, they have an uneven and narrow distribution range, and the population density is not so large as to lead us to consider that plague foci exist in the surveyed area.
