Bacteremia is the presence of viable bacteria in the bloodstream. In the WikiBiome framework, bacteremia results from bacterial translocation across compromised barriers—the gut epithelium (→ portal bacteremia) or the oral mucosa (→ systemic bacteremia during dental procedures or periodontitis).
It is distinct from Endotoxemia (LPS translocation) in that viable organisms, not just their products, enter the blood.

Gut translocation: Barrier failure from dysbiosis, metal damage (cadmium, lead), or inflammation allows gut bacteria to enter the portal circulation → liver → systemic spread.
COVID-19: SARS-CoV-2-induced gut dysbiosis and barrier disruption leads to bacterial translocation and bacteremia, contributing to cytokine storm severity.
Oral translocation: Chewing, dental procedures, or severe periodontitis cause transient bacteremia from oral pathogens (porphyromonas gingivalis, Streptococcus) into the systemic circulation → cardiovascular disease risk.
Perioperative: Post-surgical bacteremia from gut translocation; synbiotics may reduce incidence.
