^aExcept Staphylococcus lugdunensis

^bAll were Streptococcus dysgalactiae

^cAll were Enterococcus faecalis except for one sample where MC could not distinguish between E. faecalis and E. casseliflavus.

^dIn both culture and 16S sequencing Kocuria sp. was identified.

^eIncluding: Serratia marscecens, Serratia entomophila/nematodiphila, Citrobacter spp., Klebsiella spp. and Proteus spp.

^fAll were Pseudomonas aeruginosa except for one sample where Pseudomonas sp. could not be characterised to species level by 16S sequencing.

^gMycobacterium sp., Lactobacillus salivarius, Firmicutes spp., Enhydrobacter spp., Haemophilus parainfluenzae
