Question

"people with takahara's disease don't produce catalase. Although often asymptomatic, this condition can lead to recurrent oral infections by peroxide-generating bacteria. How would you diagnose a catalase deficiency?"

Would the answer be to put hydrogen peroxide on an open cut to see if it oxidizes? because it only does so when there is a catalase present

Answer 1

Yes, that is one way to diagnose a catalase deficiency. Another way would be to perform a laboratory test to measure the activity of catalase in a sample of the patient's blood or saliva.
