Microorganisms Isolated from Hospital Environmental Surfaces in Akure Metropolis, Ondo State, Nigeria

Abstract

Nosocomial infection is a rising problem in developing countries. Microorganisms Isolated from three private and public hospital environmental surfaces in Akure Metropolis, Ondo State, Nigeria were investigated in this study. Bacterial and fungal organisms were isolated and compared among the three hospitals. The study revealed that bacteria were the most predominant microorganisms found in the hospital environmental surfaces than fungi. Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Bacillus cereus were the bacterial isolates while fungi include Aspergillus fumigatus, Aspergillus niger and Candida albicans.  Staphylococcus aureus was found to be predominant bacteria but Aspergillus funmigatus was the predominant fungi. The result showed that the microbial loads of the public hospitals were higher than that of the private hospitals. The bacteria load of the male ward was found to be higher than that of the female ward while the fungal loads of each of the hospital environmental surfaces of female were higher than that of the male. The study revealed that bacteria were the most predominant microorganisms found in the hospital environment than fungi. Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Bacillus cereus were the bacterial isolates while fungi include Aspergillus fumigatus, Aspergillus niger and Candida albicans.  Staphylococcus aureus was found to be predominant bacteria. All the hospital environmental surfaces were contaminated with one or more microorganisms in the course of the research.
