| [serotype and antibiotic susceptibilities of group a hemolytic streptococci isolated in osaka, 1988-1989]. | a total of 386 strains of group a hemolytic streptococci isolated from the patients in osaka in 1988 and 1989 were type-classified by both t-agglutination and m-precipitin methods and were examined for drug-sensitivity. the results were summarized as follows. 1. from t-typing result, t-1 (28.2%) was revealed as the most dominant serotype in 1988, followed by t-4 (24.9%), and t-12 (23.2%), although not as much difference was found in the isolation rate among these three types. a similar tendency ... | 1991 | 1919129 |
| [antibiotic sensitivity of bacteria isolated from patients at 6 hospitals in osaka]. | we examined mics of 6 oral new quinolones and 4 oral cephems against bacteria isolated from patients at 6 hospitals in osaka during the period from january to june in 1990, and the following results were obtained. 1. all species excluding streptococcus pyogenes were more sensitive with less frequencies of resistance to new quinolones than to cephems. in new quinolones, tosufloxacin (tflx) was the most active against gram-positive cocci and ciprofloxacin (cpfx) and tflx had the highest activities ... | 1991 | 1960855 |
| [epidemiological survey of group a hemolytic streptococci isolated in osaka during the 21-year period between 1967 and 1987. part i. annual change of epidemic serotype]. | during the 21-year period between 1967 and 1987, a total of 6157 strains of group a streptococci isolated in osaka were type-classified by t-agglutination method. the results were summarized as follows. 1. sixteen serotypes were differentiated by the t-method during the course of investigation. the most common serotype was t-12 (37.1%), followed by t-4 (13.4%) and t-1 (10.4%). 2. the most dominant serotype was t-12 during 1968-1978, and other relatively frequent serotypes were t-4 in 1971, t-1 i ... | 1989 | 2689527 |
| [epidemiological survey of group a hemolytic streptococci isolated in osaka during the 21-year period between 1967 and 1987. part ii. antibiotic susceptibility]. | during the 21-year period between 1967 and 1987, a total of 4678 strains of group a hemolytic streptococci isolated in osaka were examined for drug sensitivity. the results were summarized as follows. 1. all strains were sensitive to the beta-lactam group of antibiotics (benzylpenicillin and cephaloridine). resistant strains (m.i.c. greater than or equal to 25 micrograms/ml) to tetracycline (tc), chloramphenicol (cp) and erythromycin (em) were isolated in this study period. the incidence of tc-r ... | 1989 | 2689528 |
| [an epidemiological study of group a, b, c, and g hemolytic streptococci isolated from elementary school children in the recent 12 years. part i. isolation trends. streptococcal diseases study group]. | during a 12-years period between september, 1980 and november, 1992, hemolytic streptococci (group a, b, c, & g) in throats of healthy school children in osaka were examined every other month. the results were summarized as follows. 1. 5,023 strains of hemolytic streptococci were detected from 11,647 specimens, 43.1%. among them, 2,395 strains (20.6%) belonged to group a, 1,647 (14.4%) to group b, 767 (6.6%) to group g and 187 (1.6%) to group c. 2. in the first half of the research, group a stre ... | 1994 | 8207294 |
