RESUMO
Serologic tests for syphilis including VDRL and TPHA tests were carried out in 5,413 VISA applicants for emigration, from January, 1981 to December, l984 The results are summarized as follows: 1. In 5,413 VISA applicants, the reactive rate of VDRL test was 2,0% totally. The reactive rate of VDRL test of male was 2. 6%, and that of female was 1. 6% 2. The reactive rate of 1983 was 1.4% and that was the lowest in annual incidence, but there was no statistically significant differences in comparing the annual incidences. 3. The reactive rate increased with age, and males above the 5 th decade revealed an especially high reactive rate. 4. The biologic false positive rate of VDRL teet was 16. 5%, in gl VDRL reactive persons, using TPHA as standard. 5. The quantitative test of VDRL showed low titer below 1: 4 in 88. 4%, and high titer above 1: 8 in 11. 6% of the applicants.

The present study has been undertaken, using 307 seemingly "normal" male rabbits sold in Korea, which were tested for sysphilis with two serologic tests, the RPR card test and the TPHA test. Among thc rabbits which were seropositive in these tests, 10 rabbits were selected for further tests, namely, the FTA test a.nd FTA-ABS test. The following results have been obtained. Nine rabbits(2.9%) were reactive in both the RPR card test and the TPHA test; 10(3.2%) were reactive in the RPR card test and non-reactive in the TPHA test; 8(2. 6%) were reactive in the TPHA test and non-reactive in the RPR card test, and 27(8.7%) were reactive in either tests. 2. The rabbits which were reactive in the TPHA test were also reactive in the FTA and FTA-ABS test. As can be seen in the results, 8.7% of the normal male rabbits sold in Korea are seropositive in the serologic tests for syphilis. Cnnsequently, all rabbit's undergoing syphilis experiments should be screened for possible reactive serologic tests and excluded from the experiments.
