Antimicrobial resistant patterns of pathogenic bacteria isolated from out- patients clinics in Mukalla, Hadhramout - Yemen

Abstract

Background: Antibiotic resistance and multi- resistanceof pathogenic bacteria is increasing, becoming a problem for the public health andthreatens lives and increases considerably to healthcare cost.

Objective: To determine the antimicrobial resistant patterns of pathogenic bacteria isolated from the Referred Out-Patients clinics in Mukalla city, Yemen.

Materials and Methods: Specimens were collected from patients at the Referred clinics to private laboratories in Mukalla cityin the period from January 2013 to July 2014. Bacterial isolates wereidentified by conventional diagnostic methods and antibiotic sensitivities testedby the disc diffusion method.

Results: The most prevalent bacterial isolates were Staphylococcus aureus (36.3%) followed by Escherichia coli (31.1%), Pseudomonas aeruginosa (19.0%), Streptococcus pneumonia, Proteus species and Streptococcus pyogens (3.4%), Klebsiella species and Haemophillus influenza (1.7%). Cefuroxime sodium and cefotaxime showed the highest resistance in Pseudomonas aeruginosa (90.9%), followed by amoxicillin/clavulanic acid, cefotaxime and cefuroxime sodium in Escherichia coli (83.3%, 77.7% and 66.7%) respectively, and cefuroxime sodium and cefotaxime to Staphylococcus aureus (71.4% and 61.9%) respectively.

Conclusion: High frequency of bacterial resistance is observed in this study indicating that the antimicrobial resistance is a serious problem.
