Antibiotics Recommended for Infected Wounds. Wound is an injury to the body that typically involves laceration and usually damage to underlying tissues. An infection is the growth of a parasitic organism, also called a germ, within the body. The onset of an infection is sudden, causing pain and swelling around the wound. Those germs, more commonly bacteria, attach to the tissues preventing the wound from healing. The bacteria can also enter the blood through the vein and cause a severe infection or sepsis.
