Microbial Spectrum and Antibiogram of Non-surgical Wounds in Children in a Rural Setting in Nigeria

The aim of this study was to determine the microbial spectrum and susceptibility pattern of non-surgical wound infections in children in a rural setting in our environment. This study was a cross sectional study of children aged 0 to 15 years in Bakassi, Nigeria. The children were screened for non-surgical wounds using an interviewer administered semi-structured questionnaire. Identified wounds were evaluated clinically for signs of infection and specimens were collected and cultured using standard microbiologic techniques. Susceptibility test was performed on all the isolated Micro-organisms. Data were collected and analysed using SPSS version 20 for windows. Sixty four wound infections out of a total of 115 wounds giving an infection rate of 55.7% were encountered. Of 64 wound cultures, 46.9% (30/64,) yielded mono-microbial growth, while poly-microbial growth of two and three microorganisms were obtained in 46.9% (30/64) and 1.6% (1/64) specimens respectively. A total of 92 organisms were isolated belonging to seven different species. Staphylococcus aureus (n= 57/92, 62.0%) and Streptococcus pyogenes (n = 30/92, 32.6%) were the predominant pathogens isolated. High rate of community acquired Methicillin Resistant Staphylococcus aureus (MRSA) (38/57, 66.7%) was observed. The microbial spectrum of non-surgical wounds of children in rural communities is wide. The high rate of antimicrobial resistance particularly MRSA and high predominance of S. pyogenes are potential sources of dire consequence in management and long term morbidity.
