Antibiograms of pathogenic bacteria isolated from laboratory rabbits in Ibadan, Nigeria

Summary Antibiotic sensitivity patterns of 21 bacterial isolates from some clinically ill New Zealand rabbits were evaluated against 12 commonly used antibiotics by the Kirby-Bauer disk-diffusion sensitivity testing method. The 21 isolates consisted of six Bordetella bronchiseptica, eight Pasteurella multocida, four Staphylococcus aureus and three Pseudomonas alcaligenes that were associated with snuffles, pneumonia, otitis media, genital infections and conjunctivitis in these groups of caged rabbits. The four bacteria species were all sensitive to kanamycin, gentamycin and enrofloxacin, with variable sensitivity to the other antibiotics tested. The results of this antibiogram could serve as a field guide in the treatment of very acute bacterial diseases of rabbit prior to the availability of the results of local sensitivity tests. Such sensitivity tests should be reviewed yearly to update this antibiogram.
