Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'бактериемия' (direct equivalent). The trap is in spelling/pronunciation, not meaning. Ensure correct stress on the 'ri' syllable.
Common Mistakes
- Misspelling as 'bacteriaemia' (extra 'i').
- Confusing it with 'septicaemia/sepsis' (bacteraemia is a finding; sepsis is the dysregulated systemic response to it).
- Incorrect plural: 'bacteraemias' is rare; 'episodes of bacteraemia' is preferred.

FAQ
Frequently Asked Questions
No. Bacteraemia is the presence of bacteria in the blood. Sepsis is a life-threatening condition where the body's response to an infection (which could be bacteraemia) causes injury to its own tissues and organs.
It is diagnosed by taking samples of blood and culturing them in a laboratory to see if bacteria grow.
Yes, transient bacteraemia can occur with minor events (like brushing teeth) and be cleared by the immune system without causing symptoms. Significant bacteraemia typically causes fever and chills.
There is no difference in meaning. 'Bacteraemia' is a British English spelling variant (using the 'ae' digraph), while 'bacteremia' is the American English spelling. The American spelling is now very common internationally in medical literature.
