Abstract

Antimicrobial resistance pattern of Enterococcus spp isolated from cockroaches in different units/wards of Ekiti State Teaching Hospital was assessed using standard microbiological methods. Selected isolates were characterized by standard cultural and biochemical tests and they were tested with different antibiotics using disk diffusion method. Antibiogram profiles show a relatively complete resistance (100%) of the isolates to cotrimoxazole, amoxicillin and cloxacillin. The least resistance was observed against gentamicin while few of the isolates were sensitive to erythromycin and tetracycline. It was observed that all the isolates across the wards/unit exhibited multiple resistances to the antibiotics used as majority showed 50% and above resistance to the antibiotics combinations. Eight selected isolates with multiple resistance harbored plasmids all of which were not less than 1.4 kbp in molecular weight. Hence, it showed that the gene coding for the isolates were located on the plasmid DNA while the remaining isolates which have no plasmid might showed gene coding for antibiotic resistance being located on chromosomal DNA. The results of the study suggest that cockroach infestation is a public health problem in Hospital.
