Etiology and antibiogram of
bacteria of public health importance from wound infection
was investigated. A total of one hundred (100) wound samples
were collected from different patients with wound infections
in some hospitals in Owerri, Imo State, Nigeria using
sterile swab sticks. Standard microbiological methods were
adopted in the isolation and determination of the
antibiogram of the bacterial isolates. A total of one
hundred and thirty-eight (138) bacterial isolates comprising
Staphylococcus aureus 39(28.3%), Escherichia coli
26(18.8%), Pseudomonas aeruginosa 22(15.9%),
Streptococcus mutans 16(11.6%), Proteus vulgaris
17(12.3%) and Proteus mirabilis 18(13.0%) were isolated.
Antibiogram of the bacterial isolates revealed zones of
inhibition ranging from 12mm to 28mm. Some of the bacterial
isolates were resistant to streptomycin, amoxicillin and
gentamycin antibiotics. The percentage resistance of Gram
positive organisms was 30%, and the percentage
susceptibility was 70%. For Gram negative organisms, the
percentage resistance of the organisms was 20%, while the
percentage susceptibility was 80%.Proper diagnosis of wound
infections is necessary before treatment in order to curb
the high rate of antibiotic resistant organisms.
