The global rise of multidrug-resistant (MDR) bacteria has reignited interest in alternative therapeutic options such as bacteriophage therapy. This study evaluates the effectiveness of bacteriophages isolated from hospital sewage in combating MDR Pseudomonas aeruginosa strains obtained from wound infections in Ahmadu Bello University Teaching Hospital, Zaria. Fifteen clinical isolates were reconfirmed using conventional biochemical tests, followed by antibiotic susceptibility testing. Eight isolates were identified as MDR. Bacteriophages were isolated using standard enrichment and double-layer agar methods and displayed visible lytic activity against the resistant strains. The findings highlight the potential of bacteriophages as an effective and economical therapeutic alternative.
