    Extended characterization of multi-drug resistant organisms colonising neonates at a tertiary hospital in Johannesburg, South Africa.
    (2024) Mntla, Nonkululeko Marcia
    Neonatal deaths remain high globally, particularly in sub-Saharan Africa. A third of deaths are due to infections, often secondary to multi-drug resistant (MDR) organisms. The purpose of this study was to investigate the prevalence of MDR ESKAPE+ C. auris colonisation amongst hospitalised neonates, to determine risk factors associated with MDR colonisation, and perform antimicrobial resistance characterization of these isolates. Two hundred and fifty-eight swabs were collected from 86 hospitalised neonates at a tertiary South African hospital between November and December 2020. A total of 135 ESKAPE+ C. auris isolates were identified; 68% were MDR. Majority of neonates (65%) were colonised with extended spectrum betalactamase (ESBL) producing Klebsiella pneumoniae, followed by extensivelydrug resistant (XDR) Acinetobacter baumannii. New Delhi metallo-beta-lactamase (NDM) producing A. baumannii were more prevalent than carbapenemase producing Enterobacterales (CPE). A prolonged hospital stay, median=14 days (p<.001) was identified as a risk factor for MDR organism colonisation. The high prevalence of MDR ESKAPE+ C. auris colonisation supports use of non-invasive samples to determine colonisation prevalence. More data are needed to develop improved surveillance systems which should incorporate colonisation swabs and clinical biomarkers in neonates with independently established risk factors.
