Expert Committees have developed antimicrobial protocols for the prevention of potential complications derived from bacteremia of oral origin, such as infective endocarditis. These preventive protocols have subsequently been revised and modified based on the extensive research that has been performed in this field, including studies on the efficacy of antimicrobial prophylaxis in the prevention of bacteremia of oral origin. This book provides insight on the potential implications of bacteremia of oral origin, and prevention of these potential implications with antibiotics and antiseptics. The book also discusses a rare cause of bateremia known as Lactobacillemia.
