Serological investigations for the leptospirosis on hospitalized patients in Choonchun Sungsim Hospital during the periods from August to November 1985 and 841 inhabitants of Kangwondo area including Choonchun, Choonsung, Inje, Chulwon, Hwachun, Gosung, Taibaik, Samchuk and Yangju area were carried out. 1. Among 58 hospitalized patients who were suspected as leptospirosis, 10 patients were detected to have antibody against Leptospira. All of positive sera had the highest antibody titer against serogroup Icterohemorrhagiae and most positive sera were also reactive to serogroup Australis and Canicola. Antibody titer of positive sera detected by microscopic agglutination(MA) test were ranging from 1 : 40 to 1 : 2,560. Antibody titer detected by ELISA method were higher than those detected by MAT(ELISA 1 : 400$\sim$1 : 25,600) and IgM titer of positive sera were generally higher than IgG titer. 2, Of 841 inhabitants in 8 area of Kangwondo, 17 persons (2,02%) possessing antibody against Leptospira were detected by ELISA method, IgG titer in positive sera were generally higher than IgM titer. Persons possessing antibody to Leptospira were distributed in both sex and in various age group, and no significant regional and occupational fluctuations were obserbed.

A serological survey for antibody of Leptospira spp. in canine was carried out from March to September, 1989 in Seoul. 182 serums collected from animal hospitals and keeping were collected and these were performed by using 12 different living antigens. In the microscopic agglutination test(MAT), being partial agglutination reaction at a serum dilution of 1：200 or over, we recorded it as positive. These results were compared with the species, sex and general conditions of canines, the areas and types of animal keeping. The results were summarized as followed ; 1. We detected the antibodies L. grippotyphosa 1 and L. icteroheamorrhagiae 1 in A area(total 48 heads ), L. canicola 1 and L. icterohaemorrhagiae 4 in B area(total 52 heads), L. hardjo 1 and L. icterohaemorrhagiae 2 in C area (total 32 heads), L. icterohaemorrhagiae 1 in D area(total 23 heads) L. grippotyposa 1 and L. icterohaemorrhagiae 2 in E area(total 27 heads) by MAT. There were positives for L. canicola 1, L. grippotyposa 2, L. hardjo 1 and L. icterohaemorrhagiae 10 in 5 areas by MAT. 2. The deteclive rate of leptospiral antibody in Jindo canine was 17.6% (3) among 17, Mixed 4.4% (4) among 90 and Exotic 9.3% (7) among 75 heads. 3. The Male(91 heads) was positive for 8.7%(8) and the female(91 heads) was positive for 6.5%(6). 4. In the vaccination, positive rate was 10.3% (7) among 55 heads, and in the unvaccination, positive rate was 5.5%(7) among 127 heads.

This experiment was to investigate the Leptospiral antibody in the pigs with the serological test by the microscopic-agglutination-test (MAT) from November 1991. to Januaury 1992. Antigen(living antigen) was used L. icterohemorrhagiae, L. pomona, L. canicola, L. hardjo, L. ballum, L. australis, L. autumnalis, L. grippotyphosa, L. tarassovi, L. pyrogenes, L. bataviae, L. hebdomadis for the serolgical test in the pigs. The result obtained are summarized as follows of the total 202 serum samples examined, 1. Among the serum samples of 202 heads, 19 heads of the pigs(9.4%) were positive. 2. Among the positive samples of 19 heads, The detected were L. icterohemorhagiae 10 heads(5.0%), L. pomona 3 heads(1.5%), L. canicola 6 heads(3.0%). 3. Antibody titers of positive sera were ranging from 1：100 to 1 : 400. Serotiters appeared to be very low, 4. The seroprevalence of Leptospira in Chechon was higher than that other districts (5. 4% -5.8%), but the lower than Chung-nam, Kyonggi(13.7-15.9%)
