Antibiotic resistance pattern of group-a beta-hemolytic streptococci isolated from north Indian children.

BACKGROUND The current resistance pattern of GABHS (group-A beta-hemolytic streptococci) in India has not been discussed. AIM To fill the above-mentioned void, we planned this study to determine the prevalence and degree of antibacterial resistance in GABHS isolates. SETTINGS AND DESIGN Children with acute pharyngo-tonsillitis who had not received antibiotic in the preceding week, attending...

Group-A beta-hemolytic streptococci resistance pattern in north Indian pediatric population.

Sir, The interesting article by Jain et al. describes the resistance pattern of GABHS (group-A beta-hemolytic streptococci) in northern India.[1] The article may be of immense interest to all clinicians. The authors mention in the abstract section that the current resistance pattern of GABHS has not been discussed in India, which is incorrect. A thorough search of literature reveals that Lloyd ...

The prevalence of emm types and Resistance to Erythromycin Pattern among group A Streptococci isolated from the throat in north of Iran

Abstract Background and objectives: Group A Streptococcus (GAS) strains have been identified by serologic methods based on surface protein antigens, T and M. Accordingly, different serotypes have been reported worldwide. Recently, the previous out of date procedures have been replaced by N-terminal emm gene sequence, which has been used in identifying more than 150 emm types. We aimed to determ...

Group B beta-hemolytic streptococci causing pharyngitis.

Group B beta-hemolytic streptococci were isolated from the throats of 49 of 1,110 patients who had pharyngitis. Compared with patients whose throat cultures were negative for beta-hemolytic streptococci, those harboring group B were more likely to have enlarged tonsils (P less than 0.001), exudate (P less than 0.02), and tender enlarged anterior cervical lymph nodes (P less than 0.01). Group B ...

Artificial elimination of drug resistance from group A beta-hemolytic streptococci.

Ten strains of beta-hemolytic streptococci were tested for elimination of resistance to macrolide antibiotics, tetracycline, and chloramphenicol. Six of the strains lost resistance after cultivation at 41 C or addition of acriflavine (0.2 mug/ml). These results suggest that determinants governing resistance to these antibiotics are located on extrachromosomal genetic elements (plasmids) that ar...
