A Breath Test Assaying for Radioactive Carbon Dioxide May Be

Question

A breath test assaying for radioactive carbon dioxide may be used to indicate the presence of
A) E. coli.
B) Pseudomonas species.
C) Streptococcus pyogenes.
D) Helicobacter pylori.
E) Bacillus cereus.

Accepted Answer

Helicobacter pylori can be detected using a breath test that measures the presence of radioactive carbon dioxide. The bacterium produces an enzyme that breaks down urea to produce carbon dioxide, which is then detected in the breath test. The other options are not associated with radioactive carbon dioxide detection.
