Wound infections are significant challenge in clinical practice, predominantly caused by bacterial colonization, which delay healing and increase patient morbidity. This study aimed to isolate, identify and determine the antibiotics susceptibility patterns of bacteria isolated from wound of patients attending Ahmad Sani Yariman Bakura Specialist Hospital, Gusau. Fifty wound samples were collected and processed microbiologically including culture, gram staining, biochemical test and serological test. The antibiotics susceptibility testing was carried out using the Kirby–Bauer’s disc diffusion method. The bacterial species isolated were Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumonia. The antibiotics susceptibility testing consistently yielded high susceptibility to amikacin across all the bacterial isolates, indicating the effectiveness of amikacin towards each isolate. However, high resistance was observed against meropenem across all the isolated species, posing a significant challenge in the effective management of wound infections. These findings highlight the prevalence of bacterial pathogens in wound infections and emphasize the growing challenge of antibiotics resistance, particularly to meropenem.

Street vended foods are widely enjoyed because they are inexpensive, easy accessible and flavorful. However, poor hygiene during their preparation and handling can lead to contamination by harmful and antibiotic-resistant bacteria. In this study, 30 street food samples were collected and tested, including momos (n=10), manchurian (n=10), and noodles (n=10). The results showed that all the samples were contaminated with S. aureus while Pseudomonas sp. was only found in the momos samples. No Escherichia coli and Salmonella sp. were detected in any of the samples. Antibiotic susceptibility results showed that most of the isolates were found to be sensitive to chloramphenicol, cefpodoxime, gentamicin, meropenem, doxycycline hydrochloride, amikacin, and tobramycin. On the other hand, a significant level of resistance was observed against ampicillin and ceftazidime in both S. aureus and Pseudomonas isolates. The presence of antibiotic-resistant bacteria in street-vended foods points to poor hygiene practices and poses a serious risk to public health. To prevent the spread of antimicrobial-resistant foodborne pathogens, regular microbial quality monitoring, improved hygiene practices, and appropriate use of antibiotics are essential.
