Objective:To evaluate the in vitro inhibitory potential of commonly available antibiotic (discs)and paediatric suspensions against bacterial species from polio-positive faecal specimens.Methods:Commonly available anti-biotic (discs)and oral,paediatric suspensions were screened for in vitro inhibitory activities against bacterial species from infantile polio-positive faecal specimens,using agar disc-diffusion and modified agar well-diffu-sion methods.Results:Isolated bacteria were Bacillus cereus,B.subtilis,Staphylococcus aureus,Streptococcus pneumoniae,Aeromonas hydrophila,Citrobacter aerogenes,Escherichia coli,Enterobacter aerogenes,Klebsiella pneumoniae,Pseudomonas aeruginosa,Proteus mirabilis,Pr.vulgaris,Shigella dysenteriae,Sh.flexneri,Sh. sonnei and Vibrio parahaemolyticus.Overall phenotypic antibiotic susceptibility rates among Gram-positive bac-terial species were between 33.3% (augmentin)and 75.0% (chloramphenicol,erythromycin and gentami-cin);higher susceptibility rates (48.6%-100.0%)were recorded among Gram-negative bacterial species, while between 7.8% /10.1% (metronidazole /ampicillin)and 25.2% /28.1 % (cotrimoxazole /septrin) were recorded towards paediatric antibiotics.Conclusions:Bacterial species from polio-positive fecal speci-mens are minimally susceptible to commonly available oral paediatric antibiotic suspensions in Nigeria.
