蛔虫卵对低温的抵抗力很强。关于蛔虫卵在自然界冬季气温条件下的生活能力问题,苏联、日本等国有过一些研究,国内的报告尚不多见。浅田(1942)及石川(1929)曾分别报告,在长春自然情况下及沈阳附近堆肥中的蛔虫卵经过冬季,一部分仍有生活能力。这二个报告对生活力问题的记载都极简要,缺乏试验方法、数据等资料。作者于1958年冬至1959年春在长春地区进行试验。取粪便中蛔虫卵,经培养证明都有发育能力,以沉淀法浓集,将沉渣包于滤 Ascaris eggs on the low temperature resistance is very strong. On Ascaris eggs in the natural conditions of winter temperatures in living conditions, the Soviet Union, Japan and other countries had some research, the domestic report is rare. Asada (1942) and Ishikawa (1929) reported separately that in the natural conditions of Changchun and roundworms of compost in the vicinity of Shenyang after winter, some still have viability. Both reports contain a very brief account of the issue of viability and lack information such as test methods and data. The author experimented in Changchun from the winter of 1958 to the spring of 1959. Take Ascaris eggs in the stool, have been proven to have developmental ability by culture, concentration precipitation method, the sediment bag filter
