Studying the sensitivity Serratia marcescens of an isolated germ from wounds to some antibiotics

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. Serratia marcescens (24) (100 %) (11) :Ampicillin, Ampiclox, Amoxciyllin Clavulinate, Clindamycin, Cephalexin, Cephalothin, Gentamicin, Neomycin, Nitrofurantion, Rifampicin, Sulfonamides. ( 50 % ) (66.6 %) Amoxciyllin (50 % ) Piperacillin Amikacin Tetracycline , Norfloxacin Doxycycline Carbenicillin (33.3%) Cephotaxims Naldixic acid (16.6 %) . (100 %) :Cephtriacxone, Co Trimoxazole, Ceftazidime, Chloramphenicol.
