  • a The table excludes reference strains (2), multiple isolates from the same patient (1 from Japan and 1 from the United States), and Chilean isolates (2). Percentages given are with respect to geographical regions. Significant (P < 0.05, Fisher's exact test) over- or underrepresentation of a group within a geographical region is marked in boldface type. Note that, as percentages are rounded to the nearest whole number, they may not total 100%.
