(Redirected from Opportunistic infections) An opportunistic infection is an infection caused by pathogens (bacteria, viruses, fungi, or protozoa) that take advantage of an opportunity not normally available, such as a host with a weakened immune system, an altered microbiota (such as a disrupted gut flora), or breached integumentary barriers.
If someone is described as being 'rough around the edges' it means they are generally good but have a few faults on the outside. Rough around the edges has many meanings: Worn out; Not polished or refined; Not great but not bad either; ans Unkempt.
However, the advent of moist wound healing has brought with it an understanding that moisture balance is the key to optimal outcomes. Excessive amounts of wound exudate can cause the periwound (within 4 cm of wound edge) skin to become macerated and even break down. This type of skin damage is call periwound moisture-associated dermatitis. The chemical composition of the wound exudate greatly affects the potential damage that can be wrought.
