Abstract:
There is a need for improved understanding of aerosol-acquired disease due to the increasing environmental load of antibiotic resistant bacteria. Multidrug-resistant Escherichia coli and Staphylococcus aureus are examples of bacteria for which the role of exposure to aerosolized organisms in disease transmission should be more closely evaluated globally. This study is aimed at evaluating the prevalence and antibiogram of S. aureus and E. coli present in market bioaerosols, located in Nwagu-Agulu, Anambra Nigeria. Impaction sample collection method was used to collect bioaerosol samples within the market using nutrient agar as the collection media, A combination of the cultural and microscopic features as well as selected biochemical tests were employed to identify the isolates. The Kirby-Bauer disk diffusion method was used to determine antibiotic resistance to selected commonly used antibiotics. A total of 76 S. aureus and 24 E. coli were isolated. Both organisms have been implicated in community-acquired infections. The most common bacteria isolated were Staphylococcus aureus. Varying levels of resistance were observed by these isolates to selected commonly use antibiotics. There is high prevalence of S. aureus and E. coli within Nwagu market Agulu, Anambra State, Eastern region of Nigeria. The organisms have very high rates of resistance to antibiotics (MDR) as reported by other workers. The government as well as Health professionals must play an important role in the prevention of community acquired infections via regular environmental monitoring of open markets bioaerosol and establishing a common permissible limits or concentration for bioaerosols within the markets.
