Antibiotic resistance of Gram negative microorganisms were investigated in outpatients and hospitalized
patients at our hospital within February-October 2001 period.Sensitivity tests were performed using NCCLS
criteria with disk diffusion method.In hospitalized patient; E.coli was the most prevalent isolate 36 (14 %)
followed by Klebsiella spp.10 ( 4%) , Pseudomonas aeruginosa 9 ( 3 %) and Proteus spp .5 (%2).
In outpatients E.coli was the most prevalent isolate 129 (49%), followed by Klebsiella spp. 44 (17%) , Proteus
spp .23 (9%) and Pseudomonas aeruginosa 6 (2%). E.coli was the most predominant bacterium in the urine from
both outpatients and hospitalized patients .E.coli from both outpatients and hospitalized patients was highly
susceptible to carbapenems, thirth generation of cefalosporins, aminoglycosides and quinolones. More than
50 % of E.coli isolates were also resistance to ampicillin. Overall, the susceptibility to Nitrofurantoin in
bacteria from outpatients was 87 % and hospitalized patients was 78 %. The corresponding figures for TMP
/SXT were 58 % and 56 % respectively.
