RESUMEN
During a period of 29 months positive hemocultures to Streptococcus agalactiae corresponding to eight adult patients have been observed. These bacteria were apparently responsible for the clinical picture in five patients. In other two patients S. agalactiae appeared in the course of a sepsis caused by other germ. The remaining patient had a transient bacteremia and no treatment was required. Septic shock and bacterial endocarditis were the cause of death in two patients. Six patients cured. Literature on this subject is reviewed and the better prognosis of sepsis due to S. agalactiae in adults than in neonates is stressed. Endocarditis and meningitis occur as severe complications with poor prognosis. In patients with endocarditis the administration of penicillin and gentamicin as well as the consideration of early surgical replacement of the affected heart valve is recommended. Intravenous penicillin and gentamicin associated with intrathecal gentamicin are indicated in meningeal infections. Vancomycin is a good substitutive antibiotic in patients with penicillin hypersensibility.
