Antibiotic susceptibility of enterobacteria isolated from one hospital in Hilla, Iraq

الملخص EN

A total of 153 isolates of enter bacteria were recovered from 187 clinical samples in one hospital In Hilla, Iraq during a period of three months.

Enter bacteria isolates were mainly recovered from urinary tract (26.7 %) and wounds (17.6 %) samples.

The following bacterial species were recovered : Escherichia coli, Klebsiella pneumoniae, K.

oxytoca, Klebsiella spp.

Proteus mirabilis, P.

vulgaris, Proteus spp., Enterobacter cloacae, E.

aerogens, Enterobacter spp., and Salmonella spp., and Citrobacter frundii.

E.

coli was prominent in urine and stool, Klebsiella in wounds, and Proteus in urine and ear samples.

A standardized method was used to determine the susceptibility of enter bacteria isolates against 14 antibiotics.

More than half of isolates were susceptible to penicillins (Amk, Amx), third generation cephalosporin (Ctx), and Rifadin (RD), but they were less susceptible to other penicillins (Pen, Amp), Gentamycin, and tetracycline.

Klebsiella pneumoniae isolates showed multiresistance to penicillin (100 %), cephalexin, Gm, Te, RD, My, and NA.

In addition to these antibiotics, half of the isolates showed resistance to extended spectrum β-lactam antibiotic cefotaxime.

Proteus mirabilis has the highest number of multi-resistant isolates.

They were highly resistant to Pen, Gm, and showed moderate resistance to Amp, cephalexin, St, Te, and My antibiotics.

High percentage of Enterobacter isolates were susceptible to all antibiotics used in this study except for P, Amp, and St.
