Antimicrobial susceptibility tests revealed that 126 ( 60.5%) of the S.aureus isolated from both the Urine and HVS samples across the state were multidrug resistant . The predominant MAR index was 0.27 as 33.2% of isolates were resistant to 3 / 11 of antibiotics tested while the least 0.64 (7/11) was shown by 0.01% of the isolates. Generally, the highest resistance was to Ceftriazone (63.8%), followed by Gentamicin (63.0%), while Ciprofloxacin gave the highest susceptibility (95.2% ) followed by Ofloxacin (92.3%). Questionnaires revealed that 75.7% (87), 72.9%(43) and 76.5% (26) (mean: 75%) that tested positive for the organism at FMC Owerri, IMSUTH Orlu and General Hospital Okigwe respectively were asymptomatic. Result analysis revealed a significant prevalence of resistant S.aureus among these outpatients who were mostly asymptomatic and unsuspecting carriers.
Conclusion:The need for routine surveillance of pregnant women for S.aureus to reduce maternal and child morbidity caused by the organism has therefore been revealed by this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
