Streptococcus sanguinis Endocarditis in a Patient Who Received Clindamycin for Dental Prophylaxis

Streptococcus sanguinis Endocarditis Involving All Valves in a Patient with Ventricular Septal Defect

Clindamycin in dentistry: more than just effective prophylaxis for endocarditis?

Clindamycin is a broad-spectrum antibiotic with activity against aerobic, anaerobic, and beta-lactamase-producing pathogens. This antibiotic has been used for many years as prophylactic treatment during dental procedures to prevent endocarditis. However, the spectrum and susceptibility of the bacteria species involved in dental infections indicate that clindamycin would also be an effective tre...

Medical dental prophylaxis of endocarditis.

Antibiotics have long been the main reason for the increase in man's longevity. Since their discovery, man has tried to reduce the level of infection by treating with antibiotics. At the same time, prophylactic use has been suggested, although this is controversial. Their routine use is not recommended, and empirical treatments at non-therapeutic doses, and indiscriminately, should be avoided, ...

The Streptococcus sanguinis Competence Regulon Is Not Required for Infective Endocarditis Virulence in a Rabbit Model

Streptococcus sanguinis is an important component of dental plaque and a leading cause of infective endocarditis. Genetic competence in S. sanguinis requires a quorum sensing system encoded by the early comCDE genes, as well as late genes controlled by the alternative sigma factor, ComX. Previous studies of Streptococcus pneumoniae and Streptococcus mutans have identified functions for the >100...

Streptococcus mutans infective endocarditis complicated by vertebral discitis following dental treatment without antibiotic prophylaxis.

We report what we believe is the first reported case of Streptococcus mutans endocarditis complicated by vertebral discitis. The case is particularly interesting and topical as it occurred in a patient with pre-existing cardiac valvular disease who had recently had a dental procedure without antibiotic prophylaxis following a dramatic shift in the UK guidelines.
