Abstract |
|
|
A survey of the antibiotic susceptibility
pattern of Staphylococcus aureus strains
from clinical and skin isolates grown at 37 and
44oC respectively were carried out in
Irrua Nigeria. Of the 240 different specimens,
50(20.8%) S. aureus isolates were
reported. The highest carrier rate of S.
aureus (48%) occurred in wound swab while
the least (8.0%) was reported on the healthy
skin of the volunteers. The susceptibility of
the clinical isolates (10.4%) was lower than the
isolates from the skin (36.7%) of the
volunteers. This difference is statistically not
significant (t = 2.087, P <0.075). The isolates
were susceptible to gentamycin (50.0%)
erythromycin (40.0%) and streptomycin (30.0%).
The S. aureus isolated was resistant to
cloxacillin, penicillin, ampicillin and
tetracycline. In our studied area S.
aureus could be effectively treated by
gentamycin, erythromycin and streptomycin. The
implication of resistance of the isolates to
penicillin, ampicillin and the common
antibiotics such as ampicillin are also
highlighted.
