Studies have been carried out to determine (a) the possible role of T. spiralis larvae in the transmission of hog cholera virus and (b) to determine the effect of elevated swine temperature on the viability of trichinae. Trichina larvae from hog cholera infected swine were freed from diaphragmatic tissue by artificial digestion. Washed and disinfected larvae transmitted hog cholera virus while the supernatant digestive fluid did not transmit the virus. Infectivity of the virus was lost when the larvae were transmitted through albino rats before administration to swine. Temperature elevation of the swine did not affect the viability of the trichinae.
(a) 旋毛虫幼虫在猪霍乱病毒传播中可能发挥的作用;(b) 猪体温升高对旋毛虫活力的影响。通过人工消化从感染猪霍乱的猪的膈肌组织中分离出旋毛虫幼虫。经洗涤和消毒的幼虫可传播猪霍乱病毒,而上清消化液则不能传播该病毒。在将幼虫接种给猪之前,先通过白化大鼠传播,病毒的传染性就会丧失。猪的体温升高并不影响旋毛虫的活力。
