Abscess is gathering of white matter due to development of bacterial infection. The bacteria get into healthy tissue and thus infection is developed in particular area. Some cells get damaged and on those spots is accumulated liquid along with infected cells.
To those spots are navigated leucocites (body protectors against infections) which die after they catch bacteria. Gathering of dead leucocites do form white matter that fills damaged area. While white matter accumulates, the healthy tissue moves away.
Gradually around abscess is formed connective tissue and walls around abscess – in this way body prevents further microorganisms spreading. When occurs rupture of abscess, the pathogens may get into the body or under the skin depending on abscess localization. Abscess may be developed in any organs including lungs, mouth, rectum and muscles. Frequently they occur on the skin, especially on the face.
Abscess symptoms
Symptoms of abscess are detemined by the spot of its location and dysfunction of organ or nerve in abscess area. Symptoms may include pain, painful palpation, local skin temperature increase, intumescence, redding and sometimes increase of body temperature. Abscess that is formed under skin usually looks like intumescence.
Before opening, it becomes white in central part because skin around it gets thin. When abscess is developed deep in the body then for the symptoms appaering it must have significant size. Unobserved deep abscess often is source of infection spreading through the whole body.

Foot-and-mouth disease
Foot-and-mouth disease is a viral infection with specific damage of mucous membrane of mouth, lips, nose, skin, interdigital folds. The pathogen is a filtering RNA containing virus of spheric form which is kept in the environment.
With foot-and-mouth disease get diseased cloven-hoofed animals (great and small cattle, pigs, sheep). In diseased animals virus is released with saliva, milk, urine, animal manures. Sensitivity of man to foot-and-mouth disease is small. Way of transmission are contact and alimentary. The disease is not transmitted from human to human.
Symptoms and course
Incubation period lasts 5 – 10 days. The foot-and-mouth disease starts with chill, high temperature, headache, acute pains in muscles and loins, weakness, loss of appetite. In 2 – 3 days appears dry mouth, photophobia, salivation, painfullness during urination. On red mucous membrane of mouth appears big number of small bubbles of millet size filled with turbid yellow liquid which in 24 hours get broken and thus sores are formed.
After opening of sores, temperature lowers. It becomes hard to speak, salivation is increased. In most patients vesicles (bubbles) may appear on skin on phalanges of hands and legs, interdigital folds. It is followed by burning sensation, creeping, itching. In most cases nails come out. Sores on mucous membrane of mouth, lips, tongue goes away in 3 – 5 days and repairs leaving no scars. Are possible new rash that delays recovery for several months. Often in children is detected gastroenteritis.
Complications
Appearing of secondary infection leads to pneumonia and sepsis.
Treatment
Hospitalization for 14 days. There is no causal treatment. Special attention is payed for care about patient, diet (spoon food, split meals). Topical treatment includes 3% solution of hydric dioxide, 0.1% rivanol, 0.1% potassium hypermanganate. For erosions is used 2.5% solution of argentic nitrate. In severe cases is recommended injection of immune serum and taking tetracycline and laevomycetin.
Preventive Measures
Veterinary supervision over animals and products animals give. Respecting sanitary and hygiene norms.
