A series of comparative IF tests have been made on serum samples from 9 SPF pigs experimentally infected with Trichinella spiralis (50-500 larvae per animal). The techniques applied included a tube test (antigen: whole Trichinella larvae), and a cryostat test (antigen: sections of Trichinella larvae). With the cryostat test a positive reaction was recorded in 2 animals already on the 6th day and in 5 animals on the 13th day p.i., while with the tube test such reaction was not demonstrated until the 27th day p.i. (2 animals). A potential risk of cross-reaction of unknown origin seems, however, to limit the application of the cryostat test to SPF- pigs.
对9只经实验感染旋毛虫（每只动物感染50 - 500条幼虫）的无特定病原体（SPF）猪的血清样本进行了一系列比较性免疫荧光（IF）试验。应用的技术包括试管试验（抗原：旋毛虫整条幼虫）和低温恒温器试验（抗原：旋毛虫幼虫切片）。在低温恒温器试验中，在感染后第6天就有2只动物记录到阳性反应，在感染后第13天有5只动物出现阳性反应，而在试管试验中，直到感染后第27天才有2只动物出现阳性反应。然而，来源不明的交叉反应潜在风险似乎限制了低温恒温器试验在SPF猪中的应用。
