Abstract :Background: This study was carried out to determine the distribution of antibiotic resistant bacterial pathogens on surface samples from Federal Teaching Hospital, Abakaliki insert ignore into journalissuearticles values(FETHA);, Ebonyi State, Nigeria. Materials and Methods: A total of 100 surface samples were collected from five insert ignore into journalissuearticles values(5); different wards including laboratory unit, pediatric ward, post natal ward, GOPD ward and children emergency ward. Isolation, phenotypic characterization and antibiogram study were carried out. Multiple Antibiotic Resistance Index insert ignore into journalissuearticles values(MARI); was determined for all isolates. Results: A total of 156 organisms comprising of 40 insert ignore into journalissuearticles values(25.64%); Staphylococcus aureus , 40 insert ignore into journalissuearticles values(25.64%); Escherichia coli , 38 insert ignore into journalissuearticles values(24.36%); Vibrio cholera , 21 insert ignore into journalissuearticles values(13.46%); Shigella spp. and 17 insert ignore into journalissuearticles values(10.90 %); Salmonella spp. were isolated and characterized. The result of the antibiotic susceptibility of isolates indicated that all strains were resistant to penicillin, nalidixic acid, cefotaxime, tetracycline, cefpirome, sulphamethoxazole, oxytetracycline and cephalothin. In contrast, the strains were susceptible to gentamicin, imipenem, streptomycin, and azithromycin. The five isolates had an average MARI between the range of 0.81- 0.88. Conclusions: This investigation has revealed that all the different areas of the hospital harbor appreciable numbers of pathogenic bacteria.
