Anaplasmosis is most important tick-borne rickettsial diseases of domestic ruminants, with Anaplasma spp. as their respective causal agents. In order to the survey prevalence of anaplasmosis in Korean native goats, we examined the Giemsa`s blood filrms from 552 grazing and 188 nongrazing-goats in Chonbuk area Namwon, Imsil and Sunchang. The conclusive diagnosis was made by observing the characteristic marginal or central bodies in the red blood cells. The infection rate of grazine and nongrazing-goats with Anaplasma spp. was 71.7% and 8.5%, respectively. In order to study about the therapeutic effects of drug for 40 grazing-oats infected with Anaplasma spp. in mountain-area, Berenil(R)(diminazene acetate) was intramuscularly injected (0.5mℓ/10kg B.W.). After 1 month, we don`t detected the parasite in the blood films from 33 goats(82.5%), but no change of significant hematological values(PCV, ESR, WBC, RBC, MCH, MCHC, PLT, MPV, PDW and HB) was observed. These results indicated that the infection rate of Anaplasma spp. was higher on grazing than nongrazing-goats and Berenil(R) as an antianaplasmal drug is recommended.

The purpose of the present survey was to evaluate the antibiotic residues in meats and internal organs such as muscle, liver, heart, kidney and spleen of cattle(n=59) and pigs (n=115). The EEC-4-plate-method were employed. The results were obtained as follows: 1. In BS 6.0, BS 7.2 and BS 8.0 used as media to detect antibiotic residues, the zone(M±SD, cm) of bacterial growth inhibition was narrow(1.40±0) in meats, whereas the zone was wide(1.69±0.25-1.88±0.23 and 1.58±0.18-1.86±0.15 in cattle and pigs, respectively) in internal organs. But in SL 8.0, it was difficult to detect the zones(0-1.40±0) of both meats and internal organs. 2. Residues of antibiotic in beef and pork were rarely detected in BS 6.0, BS 7.2 and BS 8.0(range 1.7-11.9% and 2.6-4.3%, respectively), whereas residual percentages of internal organs were relatively higher(range 69.5-96.6% and 43.5-84.3%, respectively). But in SL 8.0, it was not detected in both beef or pork, whereas they were 0-13.6% and 0-4.3% in interanal organs.

This study was undertaken to develop the monoclonal antibody(MAb) for lymphocytes of Korean native cattle by the cell hybridization of myeloma P3/NS-1/ 1-Ag-4-1 and spleen cells from BALB/c mice hyperimmunized with nylon wool column eluted peripheral T lymphocytes of Korean native cattle. The isotype of MAb KCT-14 against T lymphocyte was mouse $IgG_1$. KCT-14 positivity of mononuclear cells(MNC) from peripheral blood lymphocytes, nylon wool nonadherent and adherent-lymphocytes was 41.7%, 58.4% and 22.6%, respectively. And that of mesenteric lymph node-, spleen and thymus-MNC was 43.3%, 40.2% and 33.6%, respectively. Immunoperoxidase staining of frozen tissue sections showed that the MAb positive cells were located in the medulla of the thymus and in the paracortical area and the mantle zone of the germinal center in the lymph nodes. These results indicated that KCT-14 was one of the MAb for investigate of T lymphocyte subpopulations in the Korean native cattle.

Fugi are eukaryotic, nonphotosynthetic, filamentous or unicellular organisms, most of which grow on nonliving materials as saphrophytes. The majority are therefore opportunistic pathogens and predisposing factors often contribute to the establishment of fungal infection. These include an alteration in the normal flora of the host by prolonged administration of antibiotics, immunosup-pression, concurrent infections, damage to the skin or mucous membranes, constantly moist areas of skin or the exposure to a large infective dose, and as with fungal spores. Fungi may cause a variety of diseases which may be due directly to fungal invasion of tissue or more often to the ingestion of toxins produces by fungi in growing, standing or stored grains and other animals feeds. In this experiment, contaminated fugi were isolated and identified from animal feedstuffs such as Korean cattle, milking cows, pigs and chickens. Twelve genues were isolated from animal feeds, they are 9 from Korean cattle and milking cows feeds, 6 from pigs feeds, and 10 from chickens feeds. Among them, most frequently encountered species was Yeast(56 strains), followed by Fusarium sp(41 strains), Aspergillus sp(20 strains), each of Microsporum sp and Trichophyton sp(17 strains), Penicillium sp(12 strains), in order. And also minority was isolated as Candida sp(4 strains), Trichoderma sp(3 strains), each of Epidermophytom sp and Absida sp(2 strains), and each of Sporothrix sp and Maduromyces sp(1 strain). Among the Aspergillus sp 20 isolates, A flavus(5 strains), A nidulans(4 strains), A fumigatus(3 strains), A glucans(3 strains), A niger(3 strains) and A terreus(2 strains) were identified.
