the second factor in the pathogenesis of acne is the infection with
PROPIONIBACTERIUM ACNES. This bacterium colonises the pilosaebaceous
ducts and acts on lipids to produce a number of pro- inflammatory

There are 2 major types of acne lesions: non-inflammatory and inflammatory.
acne lesions include blackheads (open comedones-these are similar to
