      • 韓國型出血熱 發生地域 野鼠의 體外奇生體에 關한 硏究

        Korean hemorrhagic fever (KHF) occurred for the first time in Korea, 1951, although it had previously been known to both the Japanese and Russian. After Korean war, the disease has been fixed in the areas of DMZ as an endemic one, and from 100 to 400 cases have been being reported every year. 759 field rodents were collected in the endemic areas of civilian hemorrhagic fever patients in 1971 and 1972 and their ectoparasites were classified. The results of the investigation on ectoparasites of field rodents are as follows. 1. Mites harvested from field rodents collected in tile most prevalent endemic foci of KHF, Chulwon, Yunchun, Pochun and Paju are 8 genera and 14 species. The most predominant species was Laelaps agilis and, Euschongastia koreansis, Loptotrombidium pallida and Loptotrombidium palpalis in order. 2. Seasonal incidence of mites harvested from rodents was high in the dry seasons of Korea such as May, lune, October and November. Population of blood-sucking mites Loptotrombidium pallida and Loptotrombidium palpalis reached maximum about one month before the peaks of KHF patients. 3. Lice lived upon on field rodents were 2 genera 4 species. Polyplax serrata was 78% in 1971 and Polyplax enulosa was 40% in 1972. 4, Fleas collected from field rodents were 6 genera 6 species and, the most prevalent species was Ctenophthalmus congener (70%) and next was Xenopsyella cheopis. Above results are suggestive that Loptotrombidium mites, lice and fleas might play a role as a potential vector of Korean hemorrhagic fever.

        The activity of twelve biological characteristics which could serve as a means for the identification of pathogenic staphylococci was studied on 161 strains of staphylococci isolated from pathological sources, such as pus, urine, cervical discharge, blood and sputum, and the following results were obtained. 1. Approximately 90. 06 per cent of all the strains tested showed positivemannitol fermentation. Mannitol fermentation reaction revealed the highest positivity in comparison with the other biological activities. 2. The positive strains of coagulase, phosphatase, fibrinolysin production and deoxyribonuclease reaction showed 75.78, 73.55, 70.59 and 76.28 per cent, respectively. The activity of these three biological characteristics was approximately the same as that of coagulase production. 3. The positive strains which were active in gelatin liquifaction, pigment, protease, lipase, alpha-, beta-, and delta-hemolysin production were respectively less than 50 per cent. 4. The strains originated from pus and sputum were generally the highest positivity in the activity of twelve biological characteristics tested, surveying in relation to pathological sources.
