研究表明极端温度可使宿主粪便排出的微小隐孢子虫卵囊丧失感染性,而对于在温带或热带常见温度的条件下,卵囊可能维持多长时间的感染性却知之甚少。 为确定微小隐孢子虫卵囊在较宽范围内的环境温度中维持感染性的持续时间,进而为卵囊生存与感染性的关系提供流行病学依据。作者将卵囊贮存于从-10℃到35℃的10个不同温度的水浴中,在每个温度点从1到24周的8个不同时间研究卵囊对小鼠的感
Studies have shown that extremes of temperature can inactivate Cryptosporidium parvum oocysts excreted by the host’s faeces, yet little is known about how long an oocyst may remain infective under conditions of temperate or tropical temperatures. To determine the duration of infectivity maintained by Cryptosporidium parvum oocysts in a wide range of ambient temperatures, and then to provide an epidemiological basis for the relationship between oocyst survival and infectivity. The authors stored the oocysts in 10 different temperature water baths from -10 ° C to 35 ° C and studied the effect of oocysts on mice at 8 different times from 1 week to 24 weeks at each temperature point
