Susceptibility Pattern of Bacterial Isolates from Dental Caries Patients Attending Clinic at Irrua Specialist Teaching Hospital, Irrua, Nigeria

This study was carried out to evaluate the antibiotic susceptibility pattern of bacterial isolates from dental caries patients attending clinic at Irrua Specialist Teaching Hospital, Irrua, Nigeria. A total 223 bacteria samples (Streptococcus mutans = 151; Streptococcus sobrinus 36; Lactobacillus acidophilus 22; salivarius 10; mitis 4) were collected patients. Antimicrobial sensitivity testing done by single disc agar diffusion method on 24 antibiotics; selected into eight different groups 3 according action, community usage, and generation. The average group antibiotics all 25.71%, 53.81%, 13.75%, 32.74%, 10.76%, 8.52%, 0.60% 64.42% for 1 8 respectively. Specifically, most potent in Amoxicillin (42.60%), Unasyn (78.03%), Chloramphenicol (37.67%), Erythromycin (74.44%), Streptomycin (28.70%), Cefotaxime (18.39%), Pefloxacin (1.79%) Clindamycin (96.41%). There resistance Cotrimoxazole, Neomycin, Ciprofloxacin, Ofloxacin. overall each isolated 26.27%, 26.62%, 22.73%, 32.50%, 28.13% Strep. mutans, sobrinus, L. acidophilus, Considering low antibiotics, there is a need screening before an prescription treatment caries.
