Community Acquired Methicillin Resistance Staphylococcus Species and Inappropriate Antibiotics use among Women of Reproductive Age Group in Enugu, Nigeria

Abstract

Introduction: The burden of community acquired antibiotic resistance is increasing with an alarming rate in the developing countries. Many factors, including inappropriate use of antibiotics, have been suggested as the causes of spread of resistant strains in the community. Aim: To compare antibiotics susceptibility pattern of community acquired gram positive isolates among women of reproductive age with history of recent inappropriate antibiotics use and those with no history of antibiotics use. Materials and Methods: The present study was a cross-sectional descriptive study carried out from August 2020 to February 2021 at the State Teaching Hospital in Enugu, Nigeria. The participants for the study were 713 apparently healthy women who presented to the family planning unit for preconception care. All the participants were screened for asymptomatic bacteriuria by culturing their Midstream Urine (MSU). The isolated organisms were identified and Antimicrobial Susceptibility (AST) test performed using the Vitek 2. Polymerase Chain Reaction (PCR) was done for the presence of mecA gene among methicillin resistant Staphylococcus species. The antibiotic susceptibility pattern of the isolates from participants with positive history of recent antibiotic use was compared with the susceptibility pattern of those with no history of antibiotics using Chi-square test. Results: Out of the 713 participants, 59 (8.3%) had a positive history of recent antibiotics use. Only 1 (1.7%) participant had her antibiotics prescribed by the doctor while 13 (22%) and 45 (76.3%) obtain their antibiotics at the patent medicine dealer shop and through self-medication respectively. The commonest indication for inappropriate use was febrile illness followed by upper respiratory symptoms. Ciprofloxacin was the most abused antibiotics followed by amoxicillin-clavulanic acid. A 20 (83.3%) and 4 (16.7%) had Asymptomatic Bacteriuria (ASB) among those with recent antibiotic use and those with no history of recent antibiotic use respectively. All the Methicillin Resistant Staphylococcus aureus (MRSA) was isolated from the participants with recent history of inappropriate antibiotic use. Also, of significant among this group were quinolone resistant gram positive organisms. Conclusion: The ASB and multidrug resistant gram positive isolates were common among the participants with recent history of inappropriate antibiotic use. There is need to regulate antibiotics use in the community to prevent selection of multidrug resistant organisms.
