Based on the gross lesion, a survey of ulcer prevalence was carried out on pigs (3,161 heads) at a slaughterhouse in seoul from April to December in 1989. The pigs stomachs were observed anatomically and classified, according to the presence or absence of foreign bodies. Ulcer prevalence is usually classified according to size of pig farm, ages, and supplied month. The results in the studies were as follows. 1. Fundus followed the highest rate with 28.2%, esophagus with 24.5% each of cardiac and pyloric part with 7.8% and 4.1% in cases of gastric mucosa pathological studies examed total 3,161. In the acute ulcer prevalence, fundus follwed with 5.4%, esophagus with 2.6%, each of cardiac and pyloric part with 0.8% and 0.3%. When prevalent frequencies of fundus are compared with cardiac and pyloric part, they have meaning (P<0.05). 2. In the survey pig of total 3,161, pathological changes of epithelium tissue followed 44.0%, erosion(11.5%), chronic ulcer(14.8%), acute ulcer(1.6%), scar formation (1.7%) and perforation (0.9%). 3. In general monthly prevalence rates of gastric lesion are higher in spring and fall than in summer. 4. In the size of pig farms, ulcer showed higher rate at professional farms than raising on the side. 5. When there are more fluid condition in stomach and they are old, the ulcer appeared.

From 1988 to 1989, 8 strains of canine parvovirus-2 (CPV-2) were isolated from the fecal specimens from the dogs that were clinically diagnosed as canine parvoviral enteritis in the veterinary hospitals located in the regions of Taejon and Chungbuk province. Studies on biological and physicochemical properties for the isolates were carried out. The results obtained by experiments are summarized as follows. 1. Among 62 fecal samples collected from the dogs with enteric diseases, 24 (38.7%) showed the haemagglutinating activity against porcine erythrocyte, ranging from 16 to 16,384 of HA titers. 2. When 8 fecal specimens with high HA titer over 1,000 were inocultated into CRFX cells, intranuclear inclusion bodies were obseverd in all of eight specimens, of which three specimens showed cytoplasmic inolusions concurrently with the intranuclear inclusion bodies. 3. In study on species-specificity of haemagglutinating activity of the isolates, TJ-89-1 and TJ-89-2, it was found that the isolates revealed the highest haemagglutinating activity with porcine erythrocytes, showing the relatively lower haemagglutination titers with the erythrocytes from cat and rabbit. None of erythrocytes from other animals reacted with the isolates. 4. By the cross-haemagglutination inhibition test of the isolates with reference viruses and sera, the isolates were evidently identified as the strains of canine parvovirus-2. 5. In physicochemical property test, it was evident that the isolates were stable in lipid solvent, pH and heat treatment at 56℃ for 30 mm. and contain DNA genome. 6. When seven puppies were inoculated intraorally with the isolate at HA titer of 8, 192, all of the puppies showed the symptoms of anorexia, vomiting, diarrhea and died at the 5th to 10th days post inoculation(pi). The fecal samples from all of the puppies revealed significantly high HA titers afterward the 5th days pi. Body temperature and the number of total leucocytes were slightly increased at the early stage of infection, but extremely decreased at the stage of collapse. HI titers of the sera started to increase at the 2nd to 3rd days pi reaching 512 to 1,024 at the 4th to 5th day pi.

This experiment was to investigate the Leptospiral antibody in the pigs with the serological test in two areas of Kangwondo from March to April. 1989. Twelve different living antigen (L. icterohaemorrhagiae, L. pomona, L. hardjo, L. australis, L. canicola, L. autumnalis, L. grippotyphosa, L. tarassovi, L. pyrogenes, L. bataviae, L. lai and L. ballum) of Leptospira interrogans was used for the serological test in the pigs. The blood sample of 280 pigs collected from the slaughter houses were detected by microscopic-agglutination test. The results were as follows: 1. Among the serum sample of 280 heads of the pigs, 6 heads of the swine (2.14%) were positive. 2. Among the positive sample of 6 heads, 3 heads of the swine (1.1%) showed the antibody of L. icterohaemorrhagiae, 2 heads of the swine (0.7%) showed the antibody of L. canicola, and 1 head of the swine (0.4%) showed the antibody of L. pomona. 3. The positive rate of Leptospira interrogans in the swine of Kangwondo appeared to be very low.
