Objective: The aim of this research work is to find out the occurrence of PA (Pseudomonas Aeruginosa) in the infections of postoperative wound. Methodology: We collected the swab specimens from the patients who underwent surgery from basins, sinks, floors and staff of nursing from various wards of the Allied / DHQ Hospital Faisalabad. We processed all these samples in the Microbiology department of the same hospital for the evaluation of the PA as a factor of NI (Nosocomial Infections). Results: Among eighty isolates of bacteria available in the postoperative infection of wound, 33.30% (n: 20) were PA, followed by SA (Staphylococcus Aureus) as 21.70% (n: 13), Species of Klebsiella were present in 16.70% (n: 10), Escherichia coli was present in 11.70% (n: 7), Atypical coliform was present in 6.70% (n: 4), Proteus species found in 6.70% (n: 4), Streptococcus pyogenes was available in 1.70% (n: 1) & Enterococcus faecalis 1 was present in only 1.70% (n: 1). The prevalence of infection of PA was greater in females in comparison with males with a ratio of 3:2 & it was more prevalent in young patients in comparison with the elder ones. In vitro pattern of sensitivity of twenty isolates of PA displayed colistin as 100.0%, gentamicin as 75.0%, streptomycin as 30.0% & tetracycline 10.0%. Conclusion: The occurrence of PA is very high in the postoperative infections of wound. This problem can be tackle with obtaining more hygienic activities for the decrease of the nosocomial infection among patients who underwent surgery. KEY WORDS: Surgery, Pyogens, Atypical Coliform, Streptococcus, Postoperative, Bacteria.
