Occurrence of pseudomonas aeruginosa in post-operative wound infection

ABSTRACT

To determine the prevalence of Pseudomonas aeruginosa in Post-Operative Wound Infection. Design: Swab samples were collected from patients who had undergone operation, sinks, washbasins, floor and nursing staff within the different wards of Lagos University Teaching Hospital, Idi-Araba, Lagos, Nigeria. Settings The samples were obtained from the wards in the hospital and processed in the department of Medical Microbiology of the hospital. Main Outcome Measures: Assessment of Pseudomonas aeruginosa as an agent of nosocomial infections. Out of the 60 bacterial isolates found in post-operative wound infection, 20 [33.3%] were Pseudomonas aeruginosa, followed by Staphylococcus aureus 13 [21.7%], Klebsiella species 10 [16.7%], Escherichia coli 7 [11.7%], Atypical coliform 4 [6.7%], Proteus species 4 [6.7%], Streptococcus pyogenes 1 [1.7%] and Enterococcus faecalis 1 [1.7%] in that order. Pseudomonas aeruginosa infection was higher in female than male, ratio 32 and was found more among young and elderly debilitated patients. The in vitro sensitivity pattern of 20 isolates of Pseudomonas aeruginosa showed colistin [100%], gentamicin [75%], streptomycin [30%], and tetracycline [10%]. The role of Pseudomonas aeruginosa as an agent of nosocomial infections is re-emphasised
