ABSTRACT
BACKGROUND:
Neonatal colonization with multidrug-resistant (MDR) Enterobacter spp., Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterococcus faecium (ESKAPE) and Candida spp. often precedes invasive hospital-acquired infections. We investigated the prevalence and dynamics of neonatal ESKAPE and Candida spp. colonization from hospital admission until discharge (or death) and followed up for invasive disease.METHODS:
Prospective longitudinal surveillance for neonatal ESKAPE and Candida spp. colonization was conducted over 6 months at a South African regional hospital. Neonates enrolled at birth had swabs (nasal, 2× skin and rectal) collected within 24 hours and every 48-96 hours thereafter, until discharge or death. ESKAPE and Candida spp. were cultured for and antimicrobial susceptibility was performed on bacterial isolates. Whole-genome sequencing was undertaken on paired samples with the same bacterial species from colonizing and invasive disease episodes in the same child.RESULTS:
Of 102 enrolled neonates, 79% (n = 81) were colonized by ≥1 ESKAPE organism by time of discharge or death. Forty-four percent (36/81) were colonized within 24 hours of birth. Common colonizers were K. pneumoniae (70%; n = 57) and Enterobacter spp. (43%; n = 35). Almost all MDR organisms (93%) were Gram-negative. Forty-two (45%, 42/93) newborns acquired Candida spp. (skin only) colonization, commonly Candida parapsilosis (69%; n = 29). For 2 children with K. pneumoniae colonization and sepsis, the bloodstream and colonizing isolates were genetically different, whereas the single A. baumannii colonizing and blood isolate pair were genetically identical.CONCLUSIONS:
We report a high prevalence of MDR ESKAPE and Candida spp. colonization in a regional neonatal unit. Interventions to reduce the high incidence of hospital-acquired neonatal infections should include reducing high colonization rates.
