| [study of antibiotic sensitivity of streptococcus pyogenes isolated in the hospital milieu (charles nicolle hospital of tunis)]. | the purpose of the present work was to investigate the susceptibility of s. pyogenes to antimicrobial agents. the strains have been taken from the bacteriological service of charles nicolle's hospital at tunis, and that during the period from january 1988- to december 1990. the antibiogram results as well as the minimal inhibitrice concentration determined by the agar diffusion technique, reveal that s. pyogenes continues to be very susceptible to the beta-lactamins (m.i.c. of penicillin g is "0 ... | 1993 | 8505883 |
| [use of the rapid antigen detection test in group a streptococci pharyngitis diagnosis in tunis, tunisia]. | the aims of this study were to determine the contribution of commercial rapid antigen detection test (radt) in the rapid diagnosis of pharyngitis caused by group a streptococci. a total of 292 children with pharyngitis was included. a duplicate throat swabs was taken simultaneously from each patient. one of them was used for radt achievement and the other for culture. when cultures were positive, a semi-quantitative evaluation was done. throat culture and radt were positive in 59 and 72 cases re ... | 2009 | 19739414 |

| molecular mechanisms of tetracycline and macrolide resistance and emm characterization of streptococcus pyogenes isolates in tunisia. | streptococcus pyogenes or group a streptococcus, a major human pathogen, remains susceptible to beta-lactams, but resistance to other antibiotics is becoming more common. the purpose of this study was to characterize both phenotypic and genotypic epidemiological markers of group a streptococcus and to identify the mechanisms of resistance to macrolides and tetracyclines. a total of 103 strains, isolated at charles nicolle university hospital of tunis, were investigated. the rate of resistance to ... | 2011 | 21612508 |
