Abstract
Trypanosoma brucei parasites survived for 72 h or longer in refrigerated pig blood. The survival period was directly proportional to the initial parasite concentration of the sample. Infectivity of the parasites declined faster than survival, being less than 1 per 10(5) motile organisms at 72 h. The stage of infection in the pig (early vs. late) did not appear to influence subsequent survival periods or infectivity of the parasites in vitro.
摘要
布氏锥虫寄生虫在冷藏猪血中存活72小时或更长时间。存活期与样品的初始寄生虫浓度成正比。寄生虫的感染力比存活率下降得更快，在72小时时每10^5个活动生物体中的感染力小于1。猪的感染阶段（早期与晚期）似乎不影响寄生虫在体外的后续存活期或感染力。
