An indirect fluorescent antibody test for antibodies to transmissible gastroenteritis of swine.

Abstract
The indirect fluorescent antibody test was modified to provide a rapid technique for the detection, screening and titration of antibodies to transmissible gastroenteritis of pigs. Large numbers of slides containing transmissible gastroenteritis antigen were prepared by planting mixtures of infected and uninfected swine testicular cells onto multiwelled teflon-coated slides. After overnight incubation, about one-half of the cells in each well were infected which provided contrast to aid in detecting specific fluorescence in the presence of varying degrees of background staining. Following fixation, antigen slides were stored at -20 degrees C until used. The indirect fluorescent antibody test was compared to the virus neutralization test in both the screening and titration of swine sera containing transmissible gastroenteritis antibodies. The test was found to be sensitive and reliable and to offer certain advantages over the virus neutralization test.
