An investigation was conducted to determine the antibiogram of some bacterial species isolated from locally processed Tiger-nut drink “Kunun-Aya” sold at the University of Jos. The isolation, identifications, bacteria counts and antibiotic resistance pattern of the isolates against some antibiotics were done using standard microbiological techniques. The bacteriological analyses revealed the presence of three genera of bacteria species; Escherichia coli, Staphylococcus aureus and Salmonella spp with varying degrees of occurrences. The highest coliform counts ranged from (4.8×107 cfu/ml) to (3.1×107 cfu/ml). Antibiogram of the bacterial isolates revealed a varying level of resistance and susceptibility to the antibiotics tested. All the bacterial isolates were susceptible to Trimethoprim-Sulfamethoxazole. Conversely, all the isolates were highly resistant to Chloramphenicol, Sparfloxacin, Amoxicillin, Perfloxacin, Erythromycin, Amoxicillin/Clavulanate and Streptomycin except Salmonella spp. which was highly susceptible to Ciprofloxacin. Based on the result of this finding, it can be concluded that the bacterial isolates had varying levels of resistance to the antibiotics tested. The antibiotic resistance pattern exhibited by the isolates from the Tiger-nut drink ‘Kunun-Aya’ is indicative of possible abuse of the use of antibiotics and that the consumption of this beverage has potential public health implications and subsequent chemotherapeutic failures in the consumers of this local beverage in the University of Jos community.
