Some bacterial pathogens are highly infectious via the respiratory route. Determining whether the pathogen can make an enzyme that breaks down hydrogen peroxide by the catalase method could be hazardous. How? Also include in your answer how the test is performed.

Explanation:

Escherichia coli, is a type of bacteria that  lives in the intestines. It's also found in the gut of some animals. Most of them are harmless, they aid keeping the digestive tract healthy.  Though  if  contaminated food or fouled water is  consumed, some strains can cause diarrhea .

Catalase enzymes, hydroperoxidase I (HPI) and HPII, catalyze the dismutation of hydrogen peroxide to water and oxygen but they play  crucial roles in protecting cells against the effects of oxidative stress.

Some examples of  pathogenic microorganisms which produces catalase include staph, bacillus, aureus,etc
