[Endocarditis lenta caused by Lactobacillus salivarius subsp. salicinicus (author's transl)].

After two tooth extractions performed without antibiotic cover endocarditis lenta occurred in a ten-year-old girl. The causative organism isolated was Lactobacillus salivarius subsp. salicinicus, the first such reported case. The child has a small, haemodynamically insignificant, ventricular septal defect. A cure was achieved after long-term administration of penicillin G in high doses, at first combined with ampicillin. There were no complications.
