This paper dealt wih the distribution of Shigella spp. on 5 piggeries in Taegu and Kyongbuk during the period from August to October 1987. Isolated Shigella were examined for serogrouping, antimicrobial drug resistance and detection of R plasmid. Genetic properties of R plasmid in Shigella were examined for fertility inhibition (F1) and gel electrophoresis was performed for the isolation of plasmid DNA. Of total 2,978 samples from 5 piggeries, 82 strains (2.8 %) of Shigella spp. were isolated from 82 samples. The isolated strains were identified as S. dysenteriae (60 strains), S. flexneri (20 strains) and S. sonnei (2 strains). Of the 82 strains examined 67 (95.1 %) were resistant to one or more antibiotics, such as ampicillin (Am), chloramphenicol (Cm), kanamycin (Km), nalidixic acid (Na), rifampicin (Rf), streptomycin (Sm), sulfademethoxine (Su), and tetracycline (Tc) and higher resistance to Su (90.2 %), Sm (63.4 %) and Tc (63.4 %). Of the 78 resistant Shigella strains 26 (33.3 %) harbored conjugative R plasmids and the transfer frequency of Sm (50.0 %), Cm (33.3 %) resistance was much higher than that of the other drug resistance. The most common resistant patterns were SmSuTc, Su and AmSmSuTc. Out of the 26 Shigella R plasmids examined for Fi, 14 (53.8 % were Fi + and the remainder were Fi-. The plasmid DNA profiles in Shigella spp. (9 strains) isolated from pigs were confirmed as being 2 to 9 fragments by the gel electrophoresis. Their molecular size ranged 2.17 to 87.62 kilobase (Kb). All strains of Shigella spp. consisted in 15.4 Kb plasmids.

The measurement was investigated with 18 heads of fetus (60, 90, 120 days of gestation) and neonate in Korean native goats. The crown-rump length of fetuses at 60, 90, 120 days of gestation and neonate was 8.71, 20.83, 31.10 and 34.93 cm, respectively. The length of small intestine at 60, 90, 120 days of gestation and neonate was 32.28, 157.10, 303.52 and 475.06 cm, respectively. The length of large intestine at 60, 90, 120 days of gestation and neonate was 9.20, 37.70, 82.06 and 94.46 cm, respectively. The head length at 60, 90, 120 days of gestation and neonate was 2.93+-0.07, 6.67+-0.13, 8.84+-0.51 and 9.76+-0.44 cm, respectively. The width of the head at 60, 90, 120 days of gestation and neonate was 2.20+-0.13, 4.45+-0.11, 5.33+-0.20 and 5.51+-0.32 cm, respectively.

The anatomical structure of pelvic limb of thirty-one adult Korean native goats (Body weight : 14-17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The pelvic limb of the Korean native goat was composed of the hip bone, femur, patella, tibia, fibula, tarsal bones, metatarsal bone, phalanges and sesamoid bones. The hip bone consisted of the ilium, ischium and pubis which fused each other. The gluteal surface of the ilium was directed dorsolaterally. The tuber sacrale and tuber coxae were formed at the dorsal apex and ventrolateral part of the iliac wing, respectively. The lesser ischiatic notch was deeper than the greater one. The ischiatic tubercles were triangular and consisted of the dorsal, lateral and caudal ischiatic tubercles. The left and right hip bone indexes were 67.08, 66.20, the acetabular indexes were 93.78 and 92.10 and the obturator formen indexes were 53.84 and 54.77, respectively. In femur, both of the greater and lesser trochanter were well developed but the third trochanter was not observed. The left and right femur indexes were 26.55 and 26.14, head indexes were 81.66 and 81.49 and the trochlear-epicondyle indexes were 42.47 and 41.63, respectively. The patella was observed as an isosceles triangle with base lying proximal and the cranial surface was more convex. The tibial shaft was sigmoid (S-) shaped and the popliteal notch was deep. There was a large nutrient formen at the cranial aspect of the cranial intercondylar area. The tibial indexes were 22.09 (left) and 21.10 (right). The proximal extremity of the fibula was fused with the lateral condyle of the tibial but the distal one was observed independently as the malleolar bone.

This study was carried out to investigate the origin, insertion, direction of muscle fibers and structure of the ear muscles of the Korean native goat. The description was based on the dissection of fifteen Korean native goats with embalming fluid. The ear muscles of the Korean native goat were composed of the Musculus zygomaticoauricularis, M. scutuloauricularis superficialis, M. scutuloauricularis profundus, M. frontoscutularis, M. interscutularis, M. parietoauricularis, M. cervicoscutularis, M. cervicoauricularis superficialis, M. cervicoauricularis medius, M. cervicoauricularis profundus, M. auricularis profundus posterior and M. parotidoauricularis. The M. frontoscutularis clearly seperated into temporal and frontal parts in 6 cases. The M. scutuloauricularis profundus clearly separated into major and minor parts. The M. zygomaticoauricularis blended with the M. parotidoauricularis near its insertion, but not with the M. scutuloauricularis.

Effect of raising types and environmental conditions on the infection of Toxoplasma in the swine, the cat and the man were studied in Cheju Island from Sept. 1987 to Aug. 1988. Blood samples were taken from 214 conventionally raised swine in 6 villages and 506 swine raised in swine specialized farms, 122 cats raised under free moving or restrained conditions in 8 locations, 113 butchers, and 210 villagers. Toxoplasma antibody values of the blood sera were determined using the enzymelinked immunosorbent assay (ELISA). The eating type of viscera was also investigated by using questionnaires. When ELISA method was used, the percentage of Toxoplasma infect swine among the conventionally raised and of those raised in swine specialized farms were 60.7 % and 21.3 %, respectively. The respective antibody values (+- SD) were 0.589 (+- 0.310) and 0.385 (+- 0.237) and differed very significantly (p<0.01). A significant difference was also found in antibody values among 6 villages (p<0.05). The mean infection percentage of Toxoplasma in the cat was 38.2 %, the infection percentage for cats raised under free-moving and restrained condition were 37.0 % and 38.2 % respectively. The respective antibody values (+- SD) for Toxoplasma were 0.600 (+- 0.614) and 0.637 (0.645), and did not differ significantly. The infection percentage of Toxoplasma in villagers and butchers were 26.2 and 38.3 % respectively. The respective antibody values (SD) for toxoplasma were 0.429 (+- 0.195) and 0.341 (+- 0.236), and differed very significantly (p<0.01). There were also highly significant differences Pyo-sun and other village (p<0.01). Analysis of the questionnaires showed that 26.0 % of 392 villages ate liver and some villagers ate other viscera.
