Studies on modified complement fixation (MCF) test of antiblackleg bovine serum were made and the results obtained were summarized as followings. 1. The most satisfactory antigen for the MCF test among various materials studied was found to be the vegetative cells of Cl, chauvoei grown in cooked meat medium (CMM) containing 0.5mM l-(alpha) alanine and 0.1mM manganese. The antigen was prepared by inoculating the spores of Cl. chauvoei, heated at $70^{\circ}C$. for 30 minutes, into the CMM followed by incubation at $37^{\circ}C$. for 15 hours. 2. An active component contained in the factor serum of fresh normal rabbit serum was found to be C'4 fraction. It was also shown that, furthermore, DEAE cellulose sieved C'4 fraction of the factor serum enhanced antibody titer and the highest antibody titer was resulted by the addition of 0.03 ml, of the factor serum to each tube. 3. More than four fold increases of antibody titer, in antiblbckleg bovine serum-antigen system, was made with the MCF test than that with the direct complement fixation test. 4. The MCF antibody titer of cattle vaccinated against blackleg was 128 until seven month and 64 for five months thereafter.

To investigate infection rates of Anaplasma spp in Red Blood Cell(RBC) of 209 goats and to detect the Anaplasma antibody in sera of 242 goats by Complement Fixation test (CF test), the present study was practiced. The obtained results were as follows : 1. Infection rates of Anaplasma spp in RBC of blood smears, stained by the Giemsa method, were seasonally 15.3% in spring, 20.0% in summer, 39.3% In fall, 16.9% in winter, respectively. 2. The positive rates of the Anaplasma antibody in sera of goats tested by CF test were seasonally 80.2% In spring, 79.0% in summer, 85.7% in fall, 62.0% In winter, respectively.

A novel enzyme linked immunosorbent assay (ELISA) is described and compared with other established serologic tests for bovine brucellosis, namely the rose bengal test (RBT), the complement fixation test (CFT), and the tube agglutination test (TAT) approved and used in Korea. A total of 109 bovine serum samples were tested using all the 4 assays and analyzed as to specificity, sensitivity, reproducibility and predictive value. The ELISA showed 100% agreement with the CFT. The least agreement between ELISA was observed with the TAT. The agreement between the ELISA and RBT was not significantly different from that observed between the CFT and the ELISA. It is concluded that the new assay would be a good candidate for routine serologic survey for brucellosis in Korea. A protocol combining the ELISA and the CFT would increase the power for detection of serologically positive individuals and herds.

This study was undertaken to establish reliable diagnostic-procedures for the microbiological monitoring of laboratory animals. Murine(mice and rats) antibodies against hemagglutinating virus of Japan(HVJ), mouse hepatitis virus(MHV) and Mycoplasma pulmonis(Mp) were detected sensitively and specifically in experimentally and naturally infected animals' sera by an indirect enzyme-linked immunosorbent assay(ELISA), using urease conjugated antimurine immunoglobulin. The sensitivity and specificity of the complement fixation test which has been apllied widely for serodiagnosis of HVJ, MHV and Mp infections were apparently lower than those of ELISA. From these results, the ELISA was found to be available for the serodiagnosis of HVJ, MHV and Mp infections in mice and rats.

A direct complement fixation test supplemented with procomplementary porcine serum was studied using anticomplementary human, rabbit and bovine serum against Mycobacterium tuberculosis. Procomplementary activity of porcine serum varied with porcine individual and affected by anticomplementary antiserum. The procomplementary titre of porcine serum against rabbit, human and bovine serum ranged from 1:5 to 1:40. By means of complement fixation test supplemented by porcine serum, the specific complement-fixing antibody to both tuberculopolysaccharide and/or tuberculoprotein antigen was readily differentiated from the anticomplementary antibody titre.

This study was conducted to identify Babesia sp. strain isolated from the imported beef cattle, Aberdeen-angus heifers, in J farm of Jangsu Prefecture, Cheon-buk Province of Korea, morphologically, etiologically and serologically. Babesia sp. strain was purely isolated through the serial blood passages of three generations against splenectomized calves and one generation of blood passage against non-splenectomized calf(intact calf) by inhibiting the appearance of Theileria sergenti in the blood stream by means of injection of 20% oil pamaquine intramuscularly. In the splenectomized calves, the parasite multiplied markedly in blood stream soon after inoculation and parasitaemia was much severe. An elevated body temperature, anorexia, severe anaemia and icterus were observed clinically. Of three splenectomized calves, two were affected with haemoglobinuria and died. But in the non-splenectomized calf the clinical signs and parasitaemia were very mild. The means of the incubation period, the highest parasitaemia, the highest body temperature and the lowest PCV were 3.5 days, 41.1%, ${42^{\circ}C}$ and 9%, respectively, in the splenectomized calves. In calf erythrocytes Babesia sp. protozoa were polymorphic showing the round, oval, ameboid, piriform and paired piriform etc. The sizes of protozoa were $2.51{\sim}3.91{\times}1.32{\sim}2.19{{\mu}m}$ ($3.20{\times}1.60{\mu}m$). Serologically the isolated Babesia sp. were compared with other parasites, B. ovata, B. bigemina, B. bovis, T. sergenti, A. marginale and A. centrale by using the complement fixation(CF) test. As a result, the antibody titer between the homologous species were high. It was two tubes or more in the CF test. From the results obtained above the pure isolated Babesia species was identical with Babesia ovata Minami and Ishihara, 1980.

This survey was conducted for the serological confirmation on large outbreak of bovine brucellosis in two dairy farms. Serological tests were performed by the plate agglutination test, tube agglutination test, enzyme linked immunosorbent assay(ELISA), complement fixation, ,test(CFT) and rose bengal plate test(RBPT). Total 200 heads(134 heads in farm A and 66 heads in farm B) were tested. The primigravida and positive group have been raised separately in the farm A and both group have been raised together in the farm B.. The result were summarized as follows ; 1. Positive ratios in positive herds of farms by the tube agglutination test were 68.3% in farm A and 53.2% in farm B. 2. Seroconversion to brucella was observed in the primigravidas group in farm B, but was not observed in the primigravidas group in farm A. 3. All calves born in positive herd were serologically negative at time of test. 4. Positive ratio of ELISA in farm A was higher than that of tube agglutination test. 5. Number of positive reactors by the CFT, RBPT in farm A were equal to those of tube agglutination test.
