ÖzAmaç: Bu çalışmada boğaz dışı kültürlerde Streptococcus spp. üremesi olan olguların laboratuvar ve klinik özelliklerinin değerlendirilmesi amaçlanmıştır. Results: Streptococcus strains types were determined as follows; group A (9-5.6%), group B (64-39.7%), group C (2-1.2%), group D (2-1.2%), group G (2-1.2%), viridans (57-32.2%), and Streptococcus pneumonia (24-14,9%). Most frequently observed infections were urinary system infections (52-32.2%), skin and soft tissue infections (48-29.8%) and pulmonary infections (25-15.5%). In 87 (54%) of patients, there was more than one comorbid condition. While all group A Streptococcus pyogenes strains were susceptible to penicillin, 13% of Streptococcus pneumonia were resistant to penicillin and 36.3% were resistant to macrolides. Mortality was observed in eight patients. Conclusion:Invasive streptococcal infections may cause serious mortality and morbidity especially in patients with comorbid conditions. Early detection and appropriate antimicrobial therapy are most important parameters for the management of streptococcal infections.
