  1. The percentages in clinical samples add up to more than 100% since some samples contained more than one serotype. No statistical differences (Fisher exact test; p < 0.05) were found when comparing the frequency of detection of each serotype from isolates and lungs.
  2. aSerotype 2 isolates biotype I (n = 37, 75.5%) and biotype II (n = 12, 24.5%).
  3. bAll the serotype 13 isolates resulted in biotype II.
  4. cSerotype 17 isolates included biotype I (n = 23, 95.8%) and biotype II (n = 1, 4.2%).
  5. dNon-typeable.
  6. eOne isolate was initially determined as negative for serotype 2 by qPCR; however, subsequent whole-genome sequencing identified it as serotype 2.
