Question

For which of the five hydrolysis tests (starch, casein, triglycerides, tryptophan, and urea) would a positive test result be expected for:

a. the etiologic agent of acne, propionibacterium acnes? explain.

Answer 1

A positive hydrolysis test result for Propionibacterium acnes would be expected in the case of triglycerides, as this bacterium produces lipases to hydrolyze triglycerides present in sebum.

Step-by-step explanation:

For the etiologic agent of acne, Propionibacterium acnes, a positive hydrolysis test result would be expected for triglycerides. Propionibacterium acnes is known to produce lipases that hydrolyze triglycerides in sebum into glycerol and free fatty acids, a process contributing to the inflammation seen in acne.

This bacterium secretes enzymes that damage the hair follicle, causing different forms of inflammatory lesions, which is a characteristic of acne. The tests for starch, casein, tryptophan, and urea hydrolysis might not be relevant here as Propionibacterium acnes specifically targets the triglycerides found in sebum.
