Abstract The sensitivity of Serratia marcescens isolated from infected surgical wounds to 24 antibiotics were studied, they study showed that all the strains showed an absolute resistance to eleven antibiotics ; including, Ampicillin, Ampiclox, Amoxciyllin – Clavulinate, Clindamycin, Cephalexin, Cephalothin, Gentamicin, Neomycin, Nitrofurantion, Rifampicin, Sulfonamides.It also showed high resistance more than (% 50) for some of them ,as it was (% 66.6) for Amoxciyllin and (%50) for piperacillin , Amikacin and Tetracycline, the resistance rate was lower for Norfloxacin , Doxycycline and Carbenicillin at arate of (% 33.3) and for Cephotaxims and Naldixic acid it was (% 16.6) . All the isolates showed (% 100) sensitivity for Cephtriacxone, Co – Trimoxazole, Ceftazidime, Chloramphenicol.الخلاصة تم دراسة حساسیة جرثومة Serratia marcescens المعزولة من اخماج الجروح لـ (24) مضادا حیویا إذ اظهرت مقاومة مطلقة وبنسبة (100 %) لـ (11) مضادا حیویا شملت:Ampicillin, Ampiclox, Amoxciyllin – Clavulinate, Clindamycin, Cephalexin, Cephalothin, Gentamicin, Neomycin, Nitrofurantion, Rifampicin, Sulfonamides. کما اعطت مقاومة عالیة وبنسبة ( 50 % ) فأکثر لعدد منها إذ کانت نسبة مقاومتها (66.6 %) للـAmoxciyllin و(50 % ) لکل من الـ Piperacillin و Amikacin و Tetracycline , وکانت نسبة المقاومة أقل للمضادات Norfloxacin و Doxycycline و Carbenicillin وبنسبة (33.3%) أما لمضادی Cephotaxims و Naldixic acid فکانت (16.6 %) . وانها أعطت حساسیة مطلقة وبنسبة (100 %) للمضادات:Cephtriacxone, Co – Trimoxazole, Ceftazidime, Chloramphenicol.
