A study investigated the prevalence and antibiotic resistance patterns of multidrug-resistant (MDR) bacteria among patients and healthcare workers in three primary healthcare centres in Kano Metropolis, Nigeria. Researchers collected 400 urine and wound swab samples, identifying 268 culture-positive isolates. Of these, 105 (39.2%) were confirmed as MDR, with *Staphylococcus aureus*, *Escherichia coli*, and *Klebsiella pneumoniae* being the most common. Patients accounted for the majority of MDR isolates (76.19%). High resistance was observed against commonly prescribed antibiotics like ceftazidime, ceftriaxone, and augmentin. Imipenem was highly effective against Gram-negative isolates, while gentamicin showed good activity against *S. aureus*. No significant differences in susceptibility patterns were found between patients and healthcare workers.
The widespread presence of multidrug-resistant bacteria in primary healthcare settings poses a serious threat to public health, making common infections harder to treat. This research highlights the urgent need for better antibiotic management and continuous monitoring to ensure effective patient care and prevent the further spread of resistance.
The abstract highlights a critical need for improved antimicrobial stewardship programmes and continuous resistance surveillance in primary healthcare settings. These findings could inform the development of targeted diagnostic tools for rapid identification of MDR strains or new antibiotic formulations. This is early-stage research, providing foundational data for public health interventions and potential pharmaceutical or diagnostic product development.

The emergence of multidrug-resistant (MDR) bacteria in primary healthcare settings threatens the effectiveness of empirical antibiotic therapy and complicates patient management. This study determined the antimicrobial susceptibility patterns and occurrence of MDR bacteria among patients and healthcare workers (HCWs) in three primary healthcare centres (PHCs). Guringawa, Ja'en, and Murtala Muhammad Specialist Hospital in Kano Central, Nigeria. A cross-sectional survey was conducted using 400 urine and wound swab samples from patients, and urine samples from HCWs. Bacterial isolates recovered from culture were subjected to antimicrobial susceptibility testing using the Kirby–Bauer disc diffusion method on Mueller-Hinton agar, following CLSI guidelines, and isolates resistant to at least one agent in three or more antimicrobial categories were classified as multidrug resistant. Of 268 culture-positive isolates, 105 (39.2%) were confirmed as MDR, comprising Staphylococcus aureus (37.14%), Escherichia coli (26.67%), Klebsiella pneumoniae (19.05%), Proteus mirabilis (8.57%), and Pseudomonas aeruginosa (8.57%). Patients accounted for 80 (76.19%) of the MDR isolates, while HCWs contributed 25 (23.81%). High resistance was observed against ceftazidime, ceftriaxone, augmentin, erythromycin, and cefoxitin across most organisms. Imipenem retained the highest activity against Gram-negative isolates (75.0–85.7% susceptibility), while gentamicin was the most effective agent against *S. aureus* (57.1% susceptibility in patients). No statistically significant differences (p > 0.05) were observed in susceptibility patterns between patients and HCWs for any organism or antibiotic tested. These findings reveal a substantial burden of MDR bacteria circulating among both patients and healthcare workers in PHCs in Kano Metropolis, with widespread resistance to commonly prescribed antibiotics, underscoring the urgent need for antimicrobial stewardship and continuous resistance surveillance in primary healthcare settings.
