[Comparison of the sensitivity of the passive, indirect hemagglutination reaction and the latex fixation test in the demonstration of the migratory phase of experimental ascariasis (Ascaris suum) in swine].

The authoresses verified diagnostic sensitivity of two serological tests -passive indirect hemagglutination [IHA] reaction modified by the authoresses and latex-fixation test [LFT] when proving the post-invasion migratory phase of ascariasis [Ascaris suum] in experimentally infected swine. The IHA reaction was found to be more sensitive than the LFT in most cases [62.2%] by two to three values of the geometric series. The invasion can be detected by the IHA reaction from 7th to 120th day and by the LFT from 7th to 49th day after invasion.
