  • Tobacco mosaic virus (TMV) was detected from Kimchi by biological and serological assay 5. Kimchi samples three month after cooked were collected, and were inoculated on N. tabacum var. Burley 21 and NC 95. Out of 33 samples, 6 showed typical symptoms induced by TMV, local necrotic lesions on Burley 21 and mosaic on NC 95. All saps from tobacco leaves showed the mosaic symptom reacted positively against TMV antiserum by agar gel double diffusion test. Based on the results, the Kimchi is considered as one of the important inoculum sources in Korea.

  • Three hundred and sixty five samples of avian droppings, collected from parks and zoo, were investigated for the occurrence of Cryptococcus neoformans in Korea. Thirteen samples were positive for C. neoformans. All isolates were obtained from withered pigeon droppings. Identification and serotyping of isolates were determined by means of serological test and polymerase chain reaction(PCR) fingerprinting. All isolates belonged to C. neoformans var. grubbi(serotype A).

  • Sero-epidemiological study was carried out to observe the prevalence of brucellosis in 500 slaughtered as well as in 500 healthy animals in Peshawar district of N.W.F.P. All serum samples were subjected to four serological tests i.e. Standard Plate Test (SPT), Standard Tube Test (STT), Rivanol Test (RV) and 2, Mercapto-Ethanol Test (2, ME). The incidence of disease in 500 healthy animals tested by standard plate test, standard tube test, rivanol test and 2, Mercapto-ethanol test, was 2.8%, 1.8%, 1.6% and 1.2% respectively. While the incidence of brucellosis in 500 slaughter animals from Peshawar abattoir was 3.0%, 2.2%, 2.00% and 1.2% by standard plate test, standard tube test, rivanol test and 2, Mercapto-ethanol test The disease prevalence was higher in slaughtered animals as compared to healthy animals. The disease was more common in goats than sheep, also more prevalence in aged female than younger stocks. The efficacy of SPT was found more effective as compared to STT, RV, and 2, ME tests both in slaughtered as well as apparently healthy animals at Peshawar district. Standard Plate test detected 2.9%, Standard Tube test 2.0%, Rivanol test 1.8% and 2, Mercapto-ethanol test detected 1.2% positive cases in slaughtered as well as in healthy animals. So the Standard Plate Test was found to be more reliable, sensitive, and easy to performed.

  • Swine whipworm(Trichuris suis) is cosmopolitan nematode which can cause serious pathology in immature stage(larva2~larva5) of infected pigs, such as anorexia, diarrhea, anemia, and death in heavy infections. In this larval stages, it is very difficult to diagnose the infection of whipworm and to differentiate from other common swine gastrointestinal disorders such as 21 day scours which are associated with TGE virus, rota virus, coccidium, and the stress of weaning. In this experiment, the isolated antigens of Trichuris spp. were carried out to examine the structure and specificity of antigens and to select the reasonable antigens which would be used in serological diagnosis by electrophoresis, Western blotting, ELISA. The results of this experiment were as follows; 1. The common fractions of each Trichuris suis antigen were identified 28,32,45, 80kDa by SDS-PAGE with silver stain and four major fractions could be detected in positive swine sera by Western blot analysis. 2. The OD(optical density) values of somatic and excretory-secretory antigens which were reacted against positive(negative) sera from pigs infected with Trichuris suis by ELISA reader were; 1) OD values($mean{\pm}SD$) of adult somatic antigen against positive(negative) sera were $0.30{\pm}0.12(0.09{\pm}0.006)$ and third-stage larva of somatic antigen were $0.28{\pm}0.038(0.10{\pm}0.005)$. And OD values of excretory-secretory antigens of adult and third-stage larva were $0.24{\pm}0.031(0.11{\pm}0.005)$ and $0.08{\pm}0.013(0.10{\pm}0.003)$, respectively. 2) OD values of adult somatic, larval somatic antigen and adult excretory-secretory antigen response to positive sera were significantly (p<0.01) associated with negative swine sera. And the Cut-off OD values(minimum positive value) were determined to be mean negative value plus 3 SD that would minimized the risk of false positives. 3. The OD values of somatic antigens of T suis and T vulpis against swine positive(negative) sera were $0.30{\pm}0.120(0.09{\pm}0.006)$ and $0.25{\pm}0.141(0.09{\pm}0.003)$. These data mean that the somatic antigens of T suis and T vulpis were able to diagnose T vulpis infection in dogs as well as T suis infection in pigs. These results suggest that somatic antigen of third-stage larva and excretory-secretory antigen of adult T suis could be used the diagnostic antigen by serological test(ELISA) in immature Trichuris spp. infection.

  • 우리나라 씨감자에 발생하고 있는 잠복성바이러스의 종류와 이들의 감염상태를 조사하기 위하여 감자 원원종포, 원종포 그리고 원예시험장 등에서 수집한 외관상 무병 건전하게 보이는 감자와 외관상 바이러스병징이 뚜렷한 감자를 대상으로 혈청학적방법에 의해 바이러스 검정을 실시했다. 검정대상 바이러스는 Potato Virus X(PVX), Potato Virus S(PVS), Potato Virus M(PVM), 그리고 Potato Virus Y (PVY)의 4종이며, 바이러스의 검정은 van Slogteren의 미량침강법에 따라 실시했다. 결과는 다음과 같다. 1. 씨감자 생산포장에서 수집한 감자잎에서 PVX, PVS, PVM, 그리고 PVY가 검출되었는데 우리나라 감자에서 PVM이 검출되었다는 실험적 보고는 이것이 처음이다. 2. 외관상 건전하게 보이는 씨감자의 거의 $100\%$ PVX와 PVS에 약 $10\%$가 PVX+PVS+PVM에, 약 $4.5\%$가 PVX+PVS+PVY에, 그리고 $1\%$ 정도가 PVX+PVS+PVM+PVY에 각각 혼합감염되어 있었다. 3. PVX와 PVS만이 검출된 식물은 대부분 병징이 음폐되어 있었으나 PVX, PVS와 함께 PVY가 검출된 식물은 대부분 뚜렷한 병징을 나타내고 있었다. 4. 혈청학적 미량탐강법은 육안적인 관찰만으로는 검정이 어려운 PVX, PVS, PVM 및 mild strain의 PVY를 씨감자 생산지에서 대규모의 식물은 대상으로 신속정확히 검정하는데 애우 편리한 방법으로 생각된다.

  • Identification of escherchia coli K1 polysaccharide antigen isolated from urine specimens of urinary tract infections in children were performed from of 1992 to 1993 in Kyoto, Japan. The serotypes of E. coli were categorized that O1:H7, O2:H6, O2:H7, O16:H6, O18:H7, O18:H ̄, and O135:H44 among 14 strains isolated from urine specimens of urinary tract infections in children by the serological test. And, one strain (O18:H ̄, isolation rate: 7.1%) of E. coli K1 polysaccharide antigen among 14 strains were isolated from urine specimens of urinary tract infections in children by the bacteriophage test.

  • 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%)

  • In order to establish a sensitive and specific diagnostic method for detection of antibody to Salmonella pullorum, a enzyme-linked immunosorbent assay(ELISA) was designed and standardized. The diagnostic efficacy of the established ELISA was compared with that of the serum plate agglutination test and immunodiffusion test for pullorum disease. 1. The chicken hyperimmune sera to Salmonella pullorum, S gallinarum, S typhimurium and S typhi were shown the cross reaction to S pullorum antigen by serum plate agglutination test. 2. When compared the cross reaction titer of microplate agglutination test for chickens hyperimmune sera, it was found that the titer were 64 in S pullorum, 32 in S gallinarum, 4 in S typhimurium and 8 in S typhi, respectively. 3. When compared the specificity of various antigen(HA, EA, PA and SA) by the immunodiffusion test, the most suitable antigen was phenol-treated bactrium. 4. The optimal concentration of S pullorum antigen for ELISA was 1 : 160 dilution of bacterium. 5. The efficacy of the ELISA for detection of S pullorum antibody was compared with serum Plate agglutination test and immunodiffusion test in chickens infected with S pullorum. The antibody was first detected at 6 days after infection using three tests examined. The antibody was alldetected at 9 days by ELISA, at 12 days by serumplate agglutination test, at 15 days by immunodiffusion test.
