RESUMEN
The antibiotic sensitivity of forty isolates of Pseudomonas stutzeri from neurosurgical floor of the specialized surgical hospital was studied. The result indicated that twenty five isolates were sensitive to different antibiotics, six isolates were resistant to rifampicin [5mcg/disc], ampicillin [20mcg], garamycin [10mcg], cotrimoxazole [25mcg], nine isolates were resistant to garamycin and ceftriaxone [30mcg]. The objective of this study is to determine the antibiotic sensitivity of forty isolates of Pseudomonas stutzeri isolated from neurosurgical floor of the specialized surgical hospital. Pseudomonas stutzeri was identified according to Noble and Overman 1994. Antibiotic sensitivity using disc diffusion method according to Bauer and Turck 1966 was applied. Sixty and a half percent of Ps. stutzeri out the total forty isolates were sensitive to all antibiotics. Six isolates of Ps. stutzeri [15.0%] were resistant to rifampicin, ampicillin, garamycin and co-trimoxazole while nine [22.55%] isolates were resistant to garamycin and ceftriaxone. The present findings of in vitro study of antibiotic sensitivity test have shown that Ps. stutzeri are generally susceptible to aminoglycosides, carbapenems, monobactams, antipseudomonal penicillins, trimethoprime, sulfamethazole and third generation cephalosporin. The resistance of 6 isolates to rifampicin and 9 isolates to garamycin and ceftriaxone might draw attention of physicians to be aware to the treatment of Ps. stutzeri infections especially in the surgical ward and intensive care units
