Background and Objectives
Streptococcus pyogenes is recognized as an important pathogen of respiratory tract infections. The rapidly, emerging problem of antibiotic resistant Streptococcus pyogenes is a major issue nowadays. The present study aimed to evaluate the antibiotic susceptibility of Streptococcus pyogenes isolated from upper respiratory tract infections in tertiary care hospital of south Karnataka.Results
A total of 2123 specimens were received from patients with respiratory tract infections, among which, 50 Streptococcus pyogenes isolates were obtained. Out of these, 8% were not sensitive to penicillin. Using VITEK 2 system, the prevalence of resistances to cefotaxime, erythromycin, tetracycline, levofloxacin, clindamycin and ceftriaxone were 4.2%, 83%, 51%, 8.9%, 40% and 5.3% respectively.Conclusion
It is important to know about the prevalence of resistance and rising MIC values of commonly used antibiotics regarding Streptococcus pyogenes to avoid therapeutic failures.
