Figure Lengend Snippet: (A) Phylogenetic tree based on 1196 core genes of clinical H. influenzae isolates and three well-studied laboratory strains (86-028NP, ATCC 10211, and ATCC 49247). The table displays the ID of people with CF (pwCF) and the capsule presence (typeable vs non-typeable). Note that one isolate had to be excluded from genetic analysis due to poor sequence qualities. (B) Genome size (in base pairs) of the clinical isolates, grouped by time window. (C) Average genome composition of clinical isolates, with genes classified as core (present in 100% of isolates), soft-core (90–99%), shell (15–89%), and cloud (0–14%). (D) Protease activity of clinical isolates measured using the azocasein assay. (E) Siderophore production of clinical isolates measured using the chrome azurol S (CAS) assay in ssBHI medium supplemented with 2,2’-bipyridine to a final concentration of 75 μM. (F) Biofilm formation under static growth conditions measured using the crystal violet assay. Asterisks denote significance levels: ***P < 0.001; **P < 0.01; *P < 0.05.
Article Snippet: When comparing the IC 90 values for ampicillin and piperacillin–tazobactam to the reference strains ATCC 49247 (β-lactamase positive ) and ATCC 10211 (β-lactamase negative ), we observed that isolates covered the entire IC 90 space between the two references.
