Since advanced molecular methods, whole generation sequencing (WGS) in particular, are being used for microbial characterization, there have been many changes in bacterial taxonomy (Table 1).  Two of the most frequent changes are description of new species (e.g., Actinobacillus vicugnae, Glaesserella australis) and reclassification of species within the existing groups (e.g., Actinomyces into Schaalia).  Here is the summary of the most recent changes that are being reported on AHL cases with bacterial culture results.
