Trauma A natural consequence of a<unk>  is tissue trauma at the site. Trauma may consist of scratching, tearing, punture or laceration of the skin, hematoma (bruising), embedding of foreign objects, for example a tooth or hair, damage to or severing of underlying structures such as connective tissue or muscle, amputations, and the ripping off of skin and hair. If major blood vessels are damaged, severe blood loss can occur. Infection Pathogen organisms can be introduced into the<unk> . Some of the pathogens can originate from the mouth of the 'biter', the substrate onto which the injured person or<unk>  can fall or from the naturally occurring microorganisms that are present on the skin or hair of the<unk> . The advent of antibiotics improved the outcome of<unk>  wound infections. Rabies<unk> s where skin has been penetrated, most commonly by dogs and bats, transmit rabies to humans. Rabies from other<unk> s is rare. If the<unk>  is caught alive or dead with its head preserved, the head can be analyzed to detect the disease. Signs of rabies include foaming at the mouth, growling, self-mutilation, jerky behavior, red eyes, and hydrophobia. If the<unk>  cannot be captured, preventative rabies treatment is recommended in many places. Several countries are known not to have native rabies, see the Wikipedia page for prevalence of rabies.
