[Diseases associated with bloodstream infections caused by the new species included in the old Streptococcus bovis group]. / Cuadros clínicos asociados a bacteriemia causada por las nuevas especies incluidas en el antiguo grupo Streptococcus bovis.

ABSTRACT

OBJECTIVE: We sought to identify possible diseases associated with bloodstream infections caused by new species of S. bovis group isolated in blood cultures and by studying patient records METHODS: Forty-four consecutive blood culture isolates initially designated S. bovis were further characterised using phenotypic methods Patient records were examined. RESULTS: We identified 15 Streptococcus gallolyticus subsp. gallolyticus, 24 Streptococcus gallolyticus subsp. pasteurianus, and 5 Streptococcus infantarius isolates in 44 BSI episodes. CONCLUSIONS: The association between S. bovis bacteraemia and endocarditis and/or colon carcinoma is highly dependent on the causative species. Streptococcus gallolyticus subsp. gallolyticus is a surrogate for endocarditis and/or bowel disease, whereas Streptococcus gallolyticus subsp. pasteurianus is a surrogate for hepato-biliary disease.
