This is a common, but potentially serious bacterial of the skin and the soft tissues underneath the skin. Most commonly caused by Group A Streptococcus and Staphylococcus aureus, which enter through a crack or break in your skin. It can occur in almost any part of the body. On the head and face, the most common areas are the eye, eyelid, ear, and nose or nasal area. Signs and symptoms include redness of skin that tends to expand, swelling, tenderness, pain, local fever, red spots, blisters, and skin dimpling with an orange peel appearance.

This is rare fungal skin disease most commonly caused by A. fumigatus and A. flavus, but it is the second most opportunistic fungal infection in patients that are immunocompromised. Signs and symptoms: Around 5-10% of patients develop skin lesions. The lesions include single or multiple red or violet hardened plaques (broad flat lesions) or papules (small bumps). The lesions may be tender or symptom free. Patients with the primary form of this disease generally have significant fever, a change in character of the wound surface, swelling, induration, and tenderness.

This is an inflammatory condition of skin folds, induced or aggravated by heat, moisture, maceration, friction, and lack of air circulation. The condition frequently is worsened or colonized by infection, which most commonly is the fungus Candida albicans or the bacteria Staphylococcus aureus, but also may be viral or due to other fungal infections. Signs and symptoms: Commonly affects the inner thighs, genitalia, armpits, under the breasts and underside of the belly, behind the ears and web spaces between the toes and fingers. It is usually chronic with insidious onset of itching, burning, pain, and stinging in skin folds.

This disease is an inflammation of the lymphatic channels that occurs as a result of infection at a site distal to the channel. Bacterial species of group A beta-hemolytic streptococci (GABHS) are the most common cause, but it can also be caused by Staphylococcus aureus. Signs and symptoms include tender red streaks often radiate from the wound or cut toward the nearest lymph glands. Other symptoms include fever, chills, and a general sense of illness. 6 to 8% of people get this. Generally seen in males but women can get it as well.

This is a bacterial infection that spreads suddenly and rapidly and causes death to the body's soft tissue. Commonly thought as a "flesh eating disease." Group A hemolytic streptococci and Staphylococcus aureus, alone or in synergism, are frequently the initiating infecting bacteria. However, other aerobic and anaerobic bacterial pathogens may be present. Signs and symptoms include red/purple skin, severe pain, fever, vomiting, diarrhea, inflammation, tachycardia, crepitus, fluid discharge, and necrosis.

This species of bacteria is a Gram-negative, rod shaped bacteria. It is found in the soil, water, and even in hot tubs. Produces colonies that are pearlescent in appearance and have a grape-like odor. This species is an opportunistic pathogen and the fourth most frequent cause of nosocomial infections in the US. Disease symptoms: Change in tissue color, releases pigments that often color tissues green, produces chills, fever, skin lesions and shock caused by bacterial infection in bloodstream. Overall effect is tissue damage.

This disease is caused by the an antibiotic resistant strain of the bacterial species S. aureus which can be cultured from the skin, nose or mouth, and can be transmitted by person to person contact through the sharing of personal items such as towels. Systemic spread can lead to abscesses in other tissue. This disease was considered to only be a nosocomial infection, but now the antibiotic resistant strain has found it way out of the hospital setting.

This strain of bacteria is the major cause of most bite infections from animals such as dogs, cats, monkeys, and humans. It is more common than rabies. Symptoms include spreading redness and swelling, pus discharge, and form abscesses. The bacteria secrete endotoxin, which is responsible for cell death. This strain of bacteria also causes fowl cholera in chickens.

This disease is commonly called rose gardeners disease and is associated with puncture wounds from plants. Hands, arms, and legs are primary sites of infection. The causative agent is the fungus S. schenckii. Symptoms include chronic ulceration at site of wound, lymph node enlargement, healthy individuals rarely become ill and can be life threatening to immunocompromised.

Caused by the bacteria Bartonella henselae a Gram-negative bacillus, which is transmitted by a bite or scratch of a domesticated animal. Symptoms: Disease begins within a week of scratch or bite. Pus-filled pimples develop as well as painful enlargement of lymph nodes. Fever may also be present.

This disease is spread by contacting the endospores from a species of bacteria in the Genus Bacillus. The endospores can cause infections through the respiratory or digestive portals, but in the vast majority of cases of this disease (95-99%) occur when endospores enter through abrasions of the skin. The bacteria form a nodule on the skin; the cells within the nodule die forming a black mass of dead skin or tissue. Localized infections can lead to bacteremia and septicemia. If left untreated it can cause death.

This disease is usually caused when the bacteria Actinomyces israelii or Actinomyces gerencseriae is introduced into the facial tissues or neck by trauma, surgery, or infection. The bacteria cannot penetrate healthy mucosa. Symptoms: progresses slowly, painful swelling under the skin, swollen regions open to drain pus. It is more common in cattle than humans.

This disease Clostridial Myonecrosis is most commonly caused by Clostridium perfringens, a Gram-negative bacillus. Symptoms: Begin abruptly. Rapidly increasing pain localized to area of wound. Increased swelling, thin bloody fluid leaks from wound. Fluid is often brownish and may appear frothy because bacteria release gas. Skin becomes stretched because of swelling and mottled with black spots.

This disease is commonly called lockjaw and is caused by a bacterium from the genus Clostridium. The bacteria are very common in the environment and is introduced through a cut or puncture wound. Early symptoms: restlessness, irritability, difficulty swallowing, contraction of jaw muscle, and convulsions.

This disease occurs when fly larva (maggots) infect open wounds. In humans, it is usually transmitted by botflies, blowflies, and fleshflies. Signs and symptoms include development of a lump in the skin as the larva grows, larva my mover on occasion and usually larva will remain under the skin and not travel throughout the body.

This disease is a rare, but serious infection of the bone. It can occur when bacteria are introduced into the bone through and open fracture or surgery. It may also be spread from one part of the body to the bone via the bloodstream. This disease is a staff infection of the bone caused by the Gram-positive bacteria, Staphylococcus aureus. There maybe no signs or symptoms or signs and symptoms which are difficult to distinguish from other diseases. Signs and symptoms include: fever, irritability, fatigue, nausea, tenderness, redness and warmth in the area of infection, and swelling around the affected bone.

Caused by Streptobacillus moniliformis. Symptoms: Bite wound usually heals without complication. Development of chills, fever, head and muscle ache and vomiting 2 to 10 days after healing. Fever comes and goes. A rash appears followed by joint pain.

This disease is caused by the release of enterotoxin type B produce by the bacteria Staphylococcus aureus. Some signs and symptoms: confusion, high fever, vomiting, diarrhea, headaches, sunburn-like rash, skin peeling on palms and soles of feet. This disease in 1980 became epidemic in the United States and traced to women using a new super absorbent Rely tampon.

This strain of bacteria is Gram negative, motile, and curved shaped. It is found in warm waters and in shellfish and oysters. This bacterium is found in all US coastal waters, in particular the gulf coast states, so it is a common wound infection in people who frequent those waters, such as swimmers, surfers and scuba divers. As a wound infection of the skin, it produces blistering skin lesions. It can also infect the bloodstream, causing a severe and life-threatening illness characterized by fever and chills, and decreased blood pressure (septic shock). Bloodstream infections are fatal about 50% of the time.
