(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.
During your inspection, you may notice a wire-like edge on the outside of the bar rails. Be careful, these edges can be sharp. If you have a fine-tooth flat file, use it to remove these edges. A burr on the side of the bar causes drag in a cut. Another reason to remove wire-edges is to minimize chipping.A wire-edge left on the bar eventually breaks off, but sometimes it takes good rail material along with it. Removing the edge before it breaks off prevents this. burr on the side of the bar causes drag in a cut. Another reason to remove wire-edges is to minimize chipping.
