Serological Diagnosis for Swine Cysticercus Cellulosae Infection in Korea

돼지의 유구낭충(有鉤囊蟲)에 관(關)한 혈청학적시험(血淸學的試驗)

The agar gel precipitation(AGP), indirect hemagglutination(IHA) and indirect enzyme immunoassay(IEIA) tests were used to detect antibodies in pigs naturally infected with Cysticercus cellulosae in Jeju. The results obtained were summarized as follows: 1. Sera collected from pigs naturally infected with Cysticcrcus cellulosae did not react in AGP test. 2. In the IHA test for swine cysticercosis, the peak titers observed were between 1:20 and 1:160 and non-specific reaction was recognized with a few samples among control sera. 3. In the IEIA test, optical density(OD) values were obtained the best results under the condition of OPD-substrats are reacted at room temperature for 5minutes. The OD values of greater than 0.2 were determined as positive and the high titers in positive sera ranged from 1:40 to 1:1,080. 4. Antibodies to swine cysticercosis were detected by IHA and IEIA tests but the latter was more sensitive and specific than the former. 5. In the preparation of Cystisercus antigens, saline extract which was prepared the precipitate of internal membrane treated ultrasonicator were better results than other antigens for serological tests. 6. Amounts of protein in antigens was not related in direct proportion to results of serological reaction.
