*NT, nontypeable; ST, sequence type. †Four isolates were not available for microbiological characterization: 1 in 2016, 2 in 2018, 1 in 2019. ‡If the number of isolates of a specific ST was not 1, the number of isolates corresponding to that ST is indicated in brackets. §New ST found in this study. ¶Serotype was determined but the isolate was not available for multilocus sequence typing.
