Feces were collected from pigs of various ages on slaughter house and swinery in the southern area of the kangwon-do. Treponema hyodysenteriae were isolated from the feces by the method of Jenkinson. and the effects of temperature on the survival of these organism were investigated. The results abtained are summerized as follows; 1. T. hyodysenteriae were isolated from 22 fecal samples of 1,296 samples, and showed higher incidence at 4-8week age groups than other age groups. 2. The organisms were isolated from 17 samples of 329 diarrhea samples and 5 samples of 967 non-diarrhea samples. 3. T. hyodysenteriae survived long at 0-10℃ but survived short at 37℃ or above.

IBD`s antibody level and morphological change of immune organ was examined in chicken. The results were as follows; 1. Sevonty percent at 42 day and 40% at 45 day of age chickens were reacted positively by the agar gel immunodiffusion test and 42 day and 45 day of age chickens indicated 1859, 1425 by the ELISA test, respectively. 2. In 2 and 5 day young broiler chickens, the level of maternal antibody was not proper. B/B ratio showed low level, but S/B ratio and BS were normal. 3. In layer, 100% of 8 and 86 day of age chicken and 70% at 40 day of age chicken had antibody aganist IBDV. The level of antibody was high as 2293 and 3336 in 8 and 86 day of age chicken, while was low as 1186 in 40 day of age chicken. B/B ratio showed low level and S/B ratio high level, but BS was normal.

Seasonal incident rates were examined from the 981 pigs slaughtered in southern Kang-won and distribution of lesions and histopathological examination were conducted from 231 Enzootic pneumonia affected lungs. The results obtained were summarized as follows: 1. 39.7~50.2% of 981 slaughtered pigs showed pneumonia lesions without seasonal variation and the incidence rate of Enzootic pneumonia was 23.5 %. 2. The distribution of Lesions of Enzootic pneumonia lobes was observed. The right lobes were affected more frequently than the left, and the highest frequency of 79.7% being recorded in the right cardiac lobe followed by the left cardiac, right apical, intermediate, left apical, right diaphrogmatic and diaphrogmatic. 3. In histopatological observation lung lobes were forming lymphonodulus from perivascular, peribronchiolar lymphoid hyerplasia and it was remarkable to bronchostenosis.
