Lactobacillus casei endocarditis in an intravenous heroin drug addict: a case report.
A 24-year-old HIV negative unemployed intravenous heroin addict with teeth in poor condition was admitted to hospital with left hemiparesis; CT scan of the brain revealed a hypodense area in the right parietal region. He was apyrexial with marked leukocytosis and raised ESR, had an aortic diastolic murmur and an echocardiogram showed marked aortic insufficiency with possible small vegetations on the anterior leaflet of the mitral valve. Lactobacillus Casei was isolated from repeated blood cultures. Therapy with penicillin G together with netilmicin for 6 weeks led to improvement of his clinical status and an echocardiogram on discharge showed clear improvement. Regression of the cerebral lesions was also demonstrated on CT scan. We conclude that lactobacillus species should be sought in all haemoculture negative endocarditis in the presence of tooth disease.
