The present study was conducted to isolate and identify pathogenic microorganisms on the external surface of computer keyboards and computer mice. For this purpose, a total 60 samples were collected from different computer centres of Dutse, Jigawa State. The samples collected were cultured with Nutrient Agar and for further identification they were cultured on the selective media. All 60 samples were found contaminated with pathogenic bacteria (E. coli, B. licheniformis, E. aerogenes, B. epidermidis and Staphylococcus). S. aureus Gram-positive dominated the isolates. The second most common bacterial growth in all samples was B. epidermidis. Potential pathogens isolated from all results indicate that computer mouse and keyboards showed 100% Contaminated in comparison with other objects. The presence of pathogenic and commensal bacteria on these objects indicates that they might act as environmental vehicles for the transmission of potentially pathogenic bacteria.
