Streptococcus gordonii-associated infective endocarditis: Case series, literature review, and genetic study

Streptococcus gordonii-associated endocarditis is rarely reported but often associated with considerable morbidity. We describe three cases of infective endocarditis caused by S. gordonii during a four-week period in 2023, and the use of whole-genome sequencing to determine whether these isolates were genetically related. The available literature was reviewed.
