Streptococcus thermophilus bacteraemia in a patient with transient bowel ischaemia secondary to polycythaemia Stephens, Joanna and Turner, David,, 2, e000060 (2015), doi = https://doi.org/10.1099/jmmcr.0.000060, publicationName = Microbiology Society, issn = , abstract= Introduction: The ability of Streptococcus thermophilus to convert lactose into lactic acid has long been utilized by the dairy industry. A seemingly low-pathogenicity organism, to the best of our knowledge there have been no previously published reports linking the consumption of foodstuffs to bacteraemia caused by this bacterium. Case presentation: Here we present a case of a regular consumer of Activia yoghurt who developed S. thermophilus bacteraemia, probably due to transient bowel ischaemia secondary to polycythaemia. Conclusion: The isolation of this bacterium from blood cultures may indicate underlying large bowel pathology and should not necessarily be dismissed as contamination. , language=, type=
