1. Purpose The accurate diagnosis and proper treatment of group A streptococcus should be emphasized concerning about possible development of late sequelae, such as acute rheumatic fever and acute glomerulonephritis. We would like to know the recover rate of beta-hemolytic streptococci by throat swab culture at the in-patient 2. Methods The throat swab cultures and filled up flow-sheets were undertaken on 619 children who had admitted to hospital, KyungHee university hospital from may 1994 to april 1995 prospectively. At the same time on admission, throat culture was performed. 3. Results The highest recover rate of BHS(Beta-Hemolytic Streptococci)and GAS(Group A Streptococci) were seen in above 10 years old, as 9.1% and 1.9%. BHS were obtained in 39 cases(6.3%) among 619 children while GAS was obtained in 3 cases (0.4%). Among 39 specimens of BHS, 33 specimens were classified as non-grouping streptococcus. 4. Conclusion The poor recovery rate of GAS inpatient compared with normal carrier rate is likely due to possible antibiotic abuse, errors in processing samples, and epidemiologic factors such as seasons and geographic areas. It is necessary to evaluate the clinical significance of non-A,B,C,G streptococcal infections and carriers.
초등학생의 베타용혈성 연쇄구균 보균자 검출에 있어서 인두부 중복배양(duplicate throat culture)의 유용성

Purpose : The most patients with acute streptococcal pharyngitis lack of classic clinical manifestations, therefore diagnostic laboratory test such as the throat culture or a rapid antigen detection test are frequently employed in primary practices of developed countries. We'd like to know the accuracy of the throat swab culture as gold standard for diagnosis of streptococcal infection with studying the discordant and concordant rate of duplicate culture. Methods : The study included 89 normal school children (boys:50, girls:39) who were attending Uljin primary school in Uljin, Kyong Sang Buk Do on March 1996. We obtained simultaneous 2 times of throat swab from each subject, and plating and streaking on 5-7% of sheep blood agar separately. We counted the characteristic beta-hemolytic colonies after overnight incubation. Results : 1) The carrier rate of beta-hemolytic streptococci at first culture is 25.1% and second one is 29.2%. 2) Ten out of 89(11.2%) is discordant in duplicate culture. 3) Culture containing less than 50 colonies of beta-hemolytic streptococci (+2) in first culture is 70.4%, second one is 85.7%. 4) Number of colonies is less than 50 in all ten discordant children. Conclusions : The discordant rate of duplicate throat swab cullture for beta-hemolytic streptococci is 11.2%, even if the subjects are normal school children. About 5% of individuals harboring beta-hemolytic streptococci in the pharynx may be missed by a single throat culture. If we are trying to examine the patients with pharyngitis, the discordant rate will be much lower than this results.

Aspartate aminotransferase (AST) has rarely been reported to complex with immunoglobulins, resulting in an elevation in AST level. Thus, this condition should be considered in patients with asymptomatic isolated elevation of AST to avoid the misinterpretation of the test result and unnecessary diagnostic procedures. We experienced a case of isolated and persistent elevation of serum AST without other abnormal laboratory findings in a 26-year-old healthy woman. In spite of extensive investigation including liver biopsy, no definite cause for the abnormality could be discovered. Using the polyethylene glycol precipitation test, the PAGE test, and the immunoglobulin precipitation test, we identified the IgM-AST complex formation responsible for the elevation of serum AST. Clinically, the awareness and detection of this macroenzyme formation can obviate unnecessary diagnostic workup. (Korean J Gastroenterol 2001;38:124-127)

We have isolated 5 strains of Yersinia enterocolitica with biotypes from 803 fecal specimens of the patients for detection of enteric bacteria from November, 1980 to April, 1981 at Kyung Hee Medical Center. All the rectal swabs was inoculated in MacConkey, SS and Selenite broth and again streaking in MacConkey and S-S agar plates after 18 hours cultivation of Selenite broth. All the agar plates were put into the room temperature. After detecting the suspected colonies through first screen Urea agar, SIM and K.I.A. Media. It was given final identification of API Kit. all the strains were determined by Nilehn & Wauters method for biotypes. and The susceptibility tests were performed by National Committee for Clinical Laboratory Standard (N.C.C.L.S) regulation. The typical biochemical properties of the organisms were urea and ornithine positive, dextrose (no gas) and xylose were fermentative, lactose was oxidative, and indol & V.P. were variable at the room temperature, motility was negative at 35℃ and positive at 25℃. The pinpoint of colorless colonies showed red color after 72 hours at room temperature. It was difficult at times to detect the organisms. because of the size and color change of the colonies. As the result of susceptibility test, all the strains were highly susceptible to Gentamycin, Kanamycin, Amikacin, Chloramphenicol, Oxytetracycline but two strains (No 1 & 5) were susceptible to Ampicillin & Carbenicillin (Biotype 2). All the strains were resistant Cephalothin. Three of 5 strains was identified as biotype 3 and the rest as biotype 2 by Nilehn & Wauters method.
