Streptococcus gallolyticus — Streptococcus bovis / gallolyticus

Review by an infectious diseases specialist in progress · edited by a physician, AI-assisted writing · level of evidence computed from the source type · page as of 30 October 2026 · Methodology

Streptococcaceae · Gram-positive

Association forte et documentée avec le cancer colorectal. Toute bactériémie ou endocardite à S. gallolyticus est associée, dans les recommandations, à une coloscopie dans les 3-6 mois — association potentiellement curative, souvent méconnue.

Scope: dosing as described in the cited guidelines (French or international context, stated by the source), for adults with normal renal function unless stated on the line. No renal or hepatic, paediatric or pregnancy adjustment is provided systematically. These regimens have not been reviewed by any infectious-disease specialist to date.

Documented organ tropism

Organs where foci of Streptococcus gallolyticus are described in the cited literature. The reported frequency is not an individual probability.

Organ	Tropism	Level of evidence	Sources	Spread route
Heart / Endocardium	High tropism	Evidence B	2	not recorded
Colon / Alimentary system (néoplasie)	High tropism	Evidence A	3	not recorded

Spread routes recorded: 0 of 2 documented foci A focus without a route is not a focus without spread: the route is simply not recorded.
