1995-1997 Yillari arasinda izole edilen Shigella suslarinin serotip dagilimi ve cesitli antibiyotiklere direnc durumlarinin arastirilmasi

In the present study, 51 Shigella strains isolated from stool samples of 1100 patients with diarrhoeae, between May 1995 to June 1997 were serotyped and antibiotic resistance patterns were evaluated by disk diffusion method. The serotype distribution of Shigella strains were as follows; S. sonnei (53%), S. flexneri (33%), S. boydii (8%) and S. dysenteriae (6%). The highest antibiotic resistance rates were found against tetracycline (82%) and trimethoprimsulfamethoxazole (TMP-SXT) (54%), followed by ampicillin (46%), ampicillin+sulbactam (31%), and chloramphenicol (16%). There were no resistant strains against ciprofloxacin and imipenem. Only 5 strains (10%) were susceptible to all antibiotics used in this study and 19 strains (37%) showed multi-drug (3 or more antibiotics) resistance pattern.
