SUMMARY
Introduction: the aim of this study was to describe the microbial ecology and antibiotic resistance of surgical site infections (SSIs) at the Amirou Boubacar Diallo National Hospital in Niamey.
Patients and Methods: this was a prospective, descriptive, and analytical study conducted over six months at the Amirou Boubacar Diallo National Hospital in Niamey, a tertiary care hospital in Niger. The study focused on SSIs and their antibiotic resistance profiles.
Results: out of 941 surgical procedures, 34 cases of SSIs were recorded, representing a frequency of 3.61%. Males accounted for 58.82% of cases. The average age was 22.5 years ±19.80, ranging from 4 days to 72 years. The most represented age group was 5 to 15 years old (32.35%). SSIs occurred in 65% of cases following emergency surgeries and in 67.65% of cases following Altemeier class IV surgeries. The isolated organisms were predominantly Gram-positive bacilli in 58% of cases. Gram-negative bacilli producing extended-spectrum beta-lactamases (ESBL) were found in 57.69% of cases. Escherichia coli and Staphylococcus aureus were the most frequently identified pathogens, each accounting for 15.56% of cases. Among Staphylococcus aureus strains, 29% were methicillin-resistant (MRSA). The isolated organisms exhibited resistance to commonly used antibiotics.
Conclusion: SSIs are frequent and severe at the Amirou Boubacar Diallo National Hospital in Niamey due to the multidrug resistance of the isolated pathogens.
Key words: surgical site infection, antibiotic resistance, emergency surgery, postoperative complications.
