Multidrug Resistant Bacterial Pathogens in the Indoor Air and Floors of Surgical Wards in a University Hospital
Objective: The hospital environment is a major source of
nosocomial pathogens. These pathogens could contaminate and colonize surgical
wounds leading to infections. This study evaluated the bacteriological quality
of air and floors of surgical wards of a University Teaching Hospital in Abuja,
Nigeria.
Methods: Bacteriological
quality of air and floor of surgical wards of the hospital was evaluated using
passive air sampling and swabbing methods respectively. The isolates were
characterized using rapid test kits and antibiotic susceptibility was
determined by the modified Kirby-Bauer disc diffusion method.
Results: A
total of 121 bacterial isolates comprising eleven species were isolated. In the
air and floor of all the surgical wards, Staphylococcus
spp. (>42%) was the most prevalent Gram-positive bacterium followed by
Bacillus subtilis (20.4%). Among the Gram-negative bacterial isolates, Pseudomonas aeruginosa (13.0%) and Proteus mirabilis (9.0%) were the most
prevalent in the air and floor, with occasional detection of Acinetobacter baumannii and other
members of the Enterobacteriaceae
family. The bacterial isolates exhibited diverse degrees of susceptibility to
the commonly prescribed antibiotics. The isolated bacteria were mostly
sensitive to fluoroquinolones.
Conclusion: This study documented the diverse environmental
microbiota of the surgical wards of the hospital. The high resistance of the
isolated bacteria to the commonly prescribed antibiotics in the hospital
highlighted the need for improved infection control and patient safety
protocols in the hospital so as to mitigate the spread of nosocomial infections
in the surgical wards of the hospital. J
