전라남도 여천군 화정면의 한우에서 발생하는 급성폐사의 원인 조사
위성하,박승주,이정길,Wee Sung-Ha,Park Seung-Joo,Lee Chung-Gil 한국임상수의학회 1991 한국임상수의학회지 Vol.8 No.1
The sudden death syndrome has been encountered in Korean native cattle in a small island village of Yeochun, Chonnam since 1984. In an effort to diagnose the causes of the condition, 10 calves were purchased and shipped to the village to be reared conventionally. During the period of April 1988 through March 1989 the animals were clinically examined every month, samples of blood and feces collected and examined. Soils, plants and water samples were analysed, and necropsy was performed on two calves which died during the period. No abnormalities were found by clinical examination. Soil, plant and water analysis did not reveal any abnormalities which could be related to sudden death. One of the 2 dead calves was fallen and suffocated to death after the right hock was tied by rein. The other had a torsion In jejunum after plowing. Epidemiological examination revealed that two calves of one farmer died in one day from bloat. Authors explained the results and asked the people in the island to improve management of the animals, and no more sudden death occurred for 2 years.

위성하,박승주,이정길,Wee, Sung-ha,Park, Seung-joo,Lee, Chung-gil 대한수의학회 1987 大韓獸醫學會誌 Vol.27 No.2
An abattoir survey was carried out on 376 Korean native cattle reared and slaughtered in Soon-chun area to determine the prevalence of Fasciola hepatica infections. The average prevalence of fascioliasis was 44%; the infection rate had a tendency to increase with age. The mean(${\pm}SE$) length and width of the flukes were $24.9{\pm}2.5mm$ and $10.5{\pm}1.7mm$, respectively.
간질감염(肝蛭感染)이 한우혈액(韓牛血液)의 구성성분(構成成分)에 미치는 영향(影響)
위성하,박승주,이정길,Wee, Sung-ha,Park, Seung-joo,Lee, Chung-gil 대한수의학회 1988 大韓獸醫學會誌 Vol.28 No.1
Some hematological and biochemical indices were assayed in Korean native cattle naturally harbouring Fasciola hepatica infection and compared with uninfected controls. Affected animals revealed reduction in total erythrocyte count and hemoglobin content, and increase in total leukocyte count. Infected cattle had significantly lower levels of serum total protein, serum albumin and magnesium. Significantly higher values were obtained for the serum enzymes aspartate aminotransferase and alanine aminotransferase.

A field study of Lymnaea viridis, the intermediate host of Fasciola hepatica, was carried out in the eastern Chonnam area. The snail was distributed all over the place. Their major habitats were rice paddies (60.8%), followed by brooks (23.2%), irrigation canals (8.6%), and drains (5.6%). Other minor habitats included natural ponds (1.5%), lakes (0.4%), and rivers (0.1%). L. viridis was living in wet clay soil, occasionally entering water. The snails discharged egg masses when the temperature was $15{\sim}20^{\circ}C$, and the number of the snails was the highest late in October. At $9^{\circ}C$ the snails were not found on the mud: they were present deep in water or at the base of rice stubbles. These hibernation sites were discussed with the epidemiology of fascioliasis.

AR感染率이 53.7%를 나타내는 野外條件下에서 Bordetella bronchiseptica(B菌) 死菌백신을 使用, 免疫接種方法내지는 回數가 免疫效果에 미치는 影響을 檢討하였다. B菌檢出陽性率은 母子免疫4回接種群(A群)에서 8.6%, 姙娠豚 2回接種群에서 29.4%, 仔豚2回接種群(C群)에서 40.0%, 그리고 仔豚1回接種群에서 42.9%이었고 한편 非免疫對照群(E群)에서는 53.7%로써 특히 母子免疫4回接種群은 非免疫對照群에 비하여 有意性있게 菌檢出率이 낮았다(p<0.05). 仔豚의 增體量에서도 免疫群은 非免疫對照群에 有意性 있는 差異를 보였으며, 同居感染狀態下에서는 우수한 免疫效果를 나타냈음이 確認되었다. The efficacy of Borpetella bnmchiseptica bacterin was evaluated in the commercial swine herds affected with the enzootic atrophic rhinitis(AR). In this study. nasal swab cultural examination, blood serum titer to B. bronchiseptica antigen, and body weight of adjusted day from birth to 56 days post-partum were determined for individual pigs. Bacterin inoculation reduced the positive isolation rate of causative organism in 8.6% cf the piglet in group A(vaccinated 4 times on the sow and its piglets), 29.4% in group B(vaccinated twice on the sow), 40.0% in group C (vaccinated twice on the pig-lets), 42.9% in group D(vaccinated once on the piglets) and 53.7% in group E of nonvaccinaied controls. Positive isolation rate of group A was significantly different(p<0.05) from the nonvaccinated control group. The average body weight at 56 days post-partum reached a weight of 26.7 and 26.1kg of group A and C, respectively and was significantly higher compared with the nonvaccinated control group. Group A, full dose of vaccine inoculated, had an average serum-agglutinating titer ranged from 1: 160 to 1: 5120 in the piglet at 6 weeks post-partum.

This study was perfomed to examine the distribution of causative agent of piglets diarrhea in eastern Chonnam province from February 1994 to March 1995. The causative agents of diarrhea were examined by bacterial culture test, parasitological test and serological test against PED, TGE and Rota. The 35 isolated E. coli were tested for antibiotic sensitivity. The results obtained were as follows. 1. The incidence of 81 piglets with diarrhea was most prevalent as 39.5% in the age of 2 to 4 weeks, compare to 34.6% in the age of 5 to 8 weeks and 16.0% under 1 weeks and 9.9% in the age of 9 to 11 weeks after birth. 2. The incidence of 81 piglets diarrhea showed bacterial diarrhea(75.3%), viral diarrhea(35.8%) and parasitological diarrhea(18.5%). When compared the isolation frequency of each etiological agent, enteropathogenic E. coli was most prevalent as 55.5% in bacterial diarrhea, rotavirus enteritis as 18.5% in viral diarrhea and trichuriasis as 13.6% in parasitological diarrhea. 3. The complicated infection of piglets was most prevalent as 41.7% in rotavirus enteritis with enteropathogenic E. coli in 24 complicated piglets diarrhea. 4. In antibiotic sensitivity test, isolates showed moderatly resistance to Tobramycin, Amikacin, Imipenem, Trimethoprim/Sulfamethoxazole, Gentamicin, Ampicillin but sensitivty to Ticarcillin/K. The 30 E. coli isolate showed multiple drug resistances in 3 different antibiotics.

Samples of blood were taken from 293 cows and heifers in Koheung, Chonnam, which was dsignated as a place for breeding pure-bred Korean native cattle. Each animal was examined clinically and parasitologically and with the history available considered to be normal at the time of blood collection. The hematology and biochemistry values were determinded, and comparisons were made between three age groups, using the results obtained. All the values obtained were within physiological range; except the alanine aminotransferase values which were higher(P<0.05) in young than in mature or old group of cattle, no significant differences were notred between age groups.

Fecal samples were taken from 402 cows in Posung, Chonnam where was designated as a place for Korean native cattle breeding. Prevalence of intestinal parasitism were determined by the fecal examinations using the floatation and sedimintation procedures. 62.9 % of the cows were found as positive cases with excretion of the eggs of Fasciola hepatica in the fecal specimens. Of those infected with F. hepatica 97 cows free of the pathogenic intestinal parasites were chosen for albendazole treatment. Albendazole tablets (10mg / kg) were administered to the cows twice at the interval of 4 weeks. Blood samples were collected via jugular vein prior to the first treatment, four weeks after the first treatment and four weeks after the second treatment respectively. At the same time fecal samples were collected for parasitological examination by sedimintation methods. The mean treatment count was 44 fluke egg per gram of feces, which compared with 27 EPG and 17 EPG four weeks after the first and second treatment, respectively. Most of the hematological values fluctuated within the normal range during the experiment. Eosinophil counts were high initially, decreased after the first treatment and there after remained steady.
