A two-year-old male peacock (Pavo cristatus) showed acute watery green diarrhea, followed by neurological signs including torticollis and muscular tremor. By the hemagglutination inhibition test for detecting the antibody against the Newcastle disease virus (NDV), the peacock serum inhibited the agglutination of chicken red blood cells. Grossly distinctive hemorrhagic lesions were found in the mucosa of proventiculus and intestine and lung. The spleen revealed multiple variable sized necrotic foci. Histologically, the mucosa of gastrointestinal track had hemorrhagic lesions and some of them underwent ulceration. The spleen exhibited multiple variable sized necrotic foci in which fibrin exudation was marked. Central nervous system had mild non-suppulative menin-goencephalitis consisting of vasculitis, perivascular hemorrhage, gliosis and meningitis. The cells particularly in the cerebellum were degenerative to necrotic. Some of these nerve cells revealed characteristic peripheral chromatolysis. From the present serological and pathological findings, it is suggested that NDV causing death of peacock was velogenic viscerotropic strain. This is the first report of the occurrence of velogenic viscerotropic NDV in an adult peacock in Korea.

Bilateral brachial neuritis is clinically uncommon and accidentally involvement of bilateral phrenic nerves is rarely reported. We experienced a 26 year old man who developed subacute onset of asymmetric bilateral shoulder and arm weakness. The weakness slowly aggravated and finally suffered from dyspnea due to bilateral phrenic nerve palsy. Cervical spine MRI and CSF study showed no abnormality. Viral markers and other serological test showed no specific finding. Electromyographic study showed bilateral brachial axonal polyneuropathy with cervical and upper thoracic polyradiculopathy. And bilateral phrenic nerve conduction study showed no resopnse. He showed no improvement for 10 months after treatment and managed with continuous artificial ventilation. We report a case of idiopathic bilateral brachial neuritis accidentally involving bilateral phrenic nerves.

Sparganosis, an infection due to the plerocercoid of Spirometra erinacei, are found worldwide but the majority of cases occur in East Asia including Korea. This report is on a recurred case of sparganosis in the subcutaneous tissue of the right lower leg 1 year after a surgical removal of a worm from a similar region. At admission, ultrasonography (USG) of the lesion strongly suggested sparganosis, and a worm was successfully removed which turned out to be a sparganum with scolex. Since sparganum has a variable life span, and may develop into a life-threatening severe case, a patient once diagnosed as sparganosis should be properly followed-up for a certain period of time. Although imaging modalities were useful for the diagnosis of sparganosis as seen in this case, serological test such as ELISA should also be accompanied so as to support the preoperative diagnosis.

Turnip mosaic virus (TuMV) was isolated from Rorippa islandica showing mild mosaic symptom in growing field of Chinese cabbage and radish. Identification of the virus was based on host range, transmission by aphids, electron micrograph, serological reaction and hybridization detection. The virus systemically infected on Chenopodium quinoa, Nicotiana clevelandii, N. glutinosa, Brassica rapa, B. campestris subsp. pekinensis and Raphanus sativus, whereas showed local infection on C. amaranticolor, Gomphrena globosa and Tetragonia tetragonoides. The virus was transmitted by aphid (Myzus persicae). The virus particle was filamentous with 720$\times$12 nm in length, and reacted positively with an antiserum of TuMV in agar gel double duffusion test. In slot-blot hybridization using the digoxigenin(DIG)-labeled RNA probe, TuMV-RNA could be detected in sap of R. islandica infected with the virus. This is the first report of a natural infection of that virus on R. islandica.

Streptococcus suis has been identified as a major cause of contagious disease in pigs Ithas been isolated worldwide from pigs suffering from meningitis, bronchopneumonia, polyserositis, polyarthritis and septicemia. Two hundred and fifty-five lung samples of slaughter pigs with gross lung lesions were collected from Jan. to Dec. 1995 in southern Chonnam area. Isolation of S suis were tested by biochemical, serological methods and antimicrobial susceptibility. The results were summerrized as follows ; 1. S suis was Isolated from 30 of 254 pneumonic lungs, 14 Isolates were isolated only, 12 were isolated with p. multocida and 4 were isolated with unidentified Gram positive cocci. 2. In biochemical characteristics studies, all isolates were not grown in 6.5% NaCl medium, and most isolates utilized L-leucine-2-naphtylamide and trehalose, didn't utilize sorbitol, ribose and L-arabinose. 3. In slide agglutination test, 6(20%) Isolates were classified as serotype 2, 4(13.3%) isolates were as serotype l/2, 16, 2 and 2(6.6%) were as serotype 1, 4, 13. 4. S suis isolates showed marked susceptibility to amoxicillin, oxacillin, cephalothin and cepoferazone and high resistance to kanamycin, streptomycin, tetracycline and erythromycin.

One hundred eight strains of Pseudomonas aeruginosa isolated from the patients (sputum, urine, burn skin, stool and blood) of Pusan National University hospital were tested for exonezyme production, antimicrobial susceptibility and serotyping. The results obtained were as follow: In exonezyme production test, 50 strains (46.30%) produced both protease and elastase. Thirty three strains (30.55%) did not produce any exoenzyme, 18 strains (16.67%) produced only protease and 7(6.48%) stains only produced elastase. As the result of antimicrobial susceptibility by the disc diffusion method, most strains were resistant to sulfamethoxazole (96.30%). But the resistant rate against gentamicin and ticarcillin were 47.23% and 46.30% respectively. The resistant rate to other antibiotics were less than 40%. All strains could be serologically typed. Most strains were identified as type Ⅲ: among them, 51 strains were belonged to serotype E. The correlation of serotype and exoenzyme production was not found.

The aim of this study was to investigate the prevalence of bovine viral diarrhea virus (BVDV) infection in Chonbuk province. Blood samples were taken from 92 korean calves to determined their serological status against BVDV, Capture enzyme-linked immunosorbent assay (ELISA) was used to test for antigen. The number of seropositive calves ranged from 3.3% to 12.9%. Antigens against BVDV were detected in 3.3% of healthy calves, 6.4% of digestive symptom calves, 12.9% of respiratory symptom calves, respectively. Sex and age of calves had no significant differences on the prevalence of BVDV. The results indicate that transmission of BVDV may have become exposed as a result of contact with acute infected or persistently infected cattle.
