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...
متن کاملGroup 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 ...

متن کاملGroup-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 ...
