The Most Common Isolated Pathogen Bacteria from Post-Surgical Operation Cases

In this study, 300 patients who had undergone surgery and were admitted to the surgical department of the University Teaching Hospital in middle Iraq cities between March 2022 and December 2023 were included; pus is a white to yellow fluid produced after surgical procedures that contain necrotic tissues, dead WBCs, and cellular debris. 75 (40%) were in the 15 to 60 age range. The current study is expected to regulate the occurrence of surgical sites and to assess the bacteriological outline and antibiotic susceptibility of surgical site pathogens among isolates. Common pathogens isolated were the pathogens revealed different levels of antibiotic resistance; Ampicillin 95%, Bacitracin88%, Ceftriaxone80%, Ciprofloxacin 77% Chloramphenicol 65%, Erythromycin57%, Gentamicin 50%, Kanamycin 45%, Nalidixic acid35% andNitrofurantoin30%. Interestingly, there were 50 (35%) more male instances than female cases. Pathogen bacteria were detected using samples from suspicious wounds and bacteria growth media. The SSI overall incidence was 15 %. The associated risk factors were the surgeon's skills and experience, an increased age, wound classification, longer duration of surgery (> 3 h), blood transfusion, prolonged hospital stay and emergency surgery. Pseudomonas aeruginosa 22% (44/200), Acinectobacte 21% (42/200), Klebsiella ssp. 17.5% (35/200), Staphylococcus aureus 15% (30/200), Escherichia coli 13% (26/200) and Proteus mirabilis 7% (14/200).
