Abstract

During mechanical ventilation for an LRTI in children, the respiratory microbiota shifted from Haemophilus- and Moraxella-dominated profiles to profiles dominated by antibiotic-resistant Enterobacteriaceae, and Staphylococcus and Streptococcus species. https://bit.ly/3pGfvhQ

a–c) Nonmetric multidimensional scaling (NMDS) biplots based on the Bray–Curtis dissimilarity matrix visualising the overall microbiota composition in the a) nasopharynx (NP), b) saliva and c) endotracheal aspirate (ETA) at time of intubation, extubation and after 2 months recovery time, along with eight biomarker operational taxonomic units. Ellipses represent the standard deviation of the data points per subgroup. Alluvial plots of cluster transitions in the d) NP, e) saliva and f) ETA between time of intubation, extubation and after 2 months recovery time. Hierarchical clustering of all samples based on the Bray–Curtis dissimilarity matrix identified seven distinct clusters, characterised by either Streptococcus (1) (STREP 1), Moraxella catarrhalis/nonliquefaciens (MOR), Haemophilus influenzae/haemolyticus (HAEMO), Corynebacterium propinquum/pseudodiphtheriticum with Dolosigranulum pigrum (COR/DOL), Streptococcus salivarius (7) (STREP 2), Enterobacter/Klebsiella (ENTERO), or Staphylococcus aureus/epidermidis (STAPH). Stacked bars represent the number of samples in each cluster per time point, and connections between bars represent transitions of participants with two consecutive samples available between time points.
