n = number of samples in a given category
(%) = n/Number of samples with results available * 100
S = sensitive; I = intermediate; R = resistant
NT = not tested
Note: None of the serotypes are tested for Amoxicillin/Clavulanate and Cefuroxime; For serotype 6A, only 1 sample was sensitive for Azithromycin; For serotypes 15A and 15B, only 1 sample was sensitive for each mentioned antibiotic; Serotype 3 had 2 samples sensitive for each antibiotic and Not Tested for Cefotaxime; Serotype 10A had 1 sample sensitive for all antibiotics; Serotype 20 had 1 sample sensitive for all antibiotics, Not Tested for Chloramphenicol and Missing for other; Serotype 16F and 23F had 1 sample resistant to Tetracycline, 1 sample Not Tested for Cefotaxime, 1 missing for Other and 1 sample sensitive for other antibiotics
