영문 초록

Investigations into the bacteriology and epidemiological features of streptococcus suis typeⅡ infections, especially in naturally-occurring field outbreaks of meningitis and its carrier state were carried out from June 1987 to December 1989 at intensive pig farms in parts of Seoul, Kyounggi, Chungchong and Kyoungnam areas. Also determined were isolated frequency of streptococci in various sources of effected pigs and antibiotics susceptibilities of the isolates. The results obtained were summarized as follows: 1. Streptococci were isolated from porcine specimen submitted to the lab. from affected pig farms and 48 strains isolated from pigs of different clinical symptoms belonged to 14 brains, 23 lungs and 11 feces. 2. The brain diseased pigs ranged mostly from 30 to 50 days of age and main clinical symptoms of the disease were CNS sign and meningitis. The morbidity and mortality of this pig weaned in a part of pig farms were 4 to 10 and 30 percent, respectively. 3. Most of brain-origin streptococci(78.7%) was belonged to Lancefield group D and identified as Streptococcus suis typeⅡ by biological and additional serological examinations. Other 3 strains were divided to group C, group F and group G.
