Listeriosis - a rare diseasecaused by germs Listeria monocytogenes, which may be in the soil, some foods, animal excrement.

main carriers of listeria are birds and animals.Pathogens resistant in the external environment.They are able to persist and multiply in the soil at moderate and low temperature for many months.Furthermore, Listeria monocytogenes bacteria can exist in milk and meat at a temperature of 4-6 ° C.Boiling die within 3-5 minutes.

There are cases of listeriosis infection from a sick animal.But most people infected by contaminated food.This is usually meat, milk, soft cheeses, which have not passed the required cooking.Sometimes listeriosis spread by airborne droplets.

pathogenic bacteria enter the human body through the mucous membranes generally the gastrointestinal tract, less through skin lesions.Spreading blood or lymph, the causative agent of listeriosis cause

febrile response.Listeria accumulate in the tonsils, lymph nodes and other organs.There they multiply, causing local inflammation.In the case of active development of listeriosis in the tissues of the internal organs and lymph nodes are formed necrotic nodules (listeriomy).sepsis (blood infection) may develop in severe cases.

Symptoms of listeriosis

When the incubation period is 3-45 days.The disease may be acute, subacute, abortifacient (in pregnant women), chronic.A person can be a carrier of the bacteria for a long time, without the expressed symptoms of listeriosis.

disease usually develops in anginal-septic form.Symptoms of listeriosis this form is very similar to the symptoms of catarrhal or follicular tonsillitis.Anginal-septic form is cured for 5-7 days.

more complex form of listeriosis - fusospirochetal angina, which usually lasts 12-14 days.Symptoms of listeriosis this form following - fever, regional lymphadenitis (inflammation of the lymph nodes) may be a runny nose and cough.Dramatically increasing, redden tonsils, and they are covered by films.

Sometimes listerioznaya angina can go into sepsis.This is accompanied by intoxication, high fever, enlargement of the spleen and liver, white plaque on the tonsils, skin rash.There

nervous form of the disease.In this case, the symptoms of listeriosis are the same as in non-specific bacterial lesions of the central nervous system.They manifest rigidity (increased muscle tone) neck, signs entsifalita, paralysis, paresis (loss of muscle strength) and other symptoms.During this form listeriosis develops as brain abscess, meningoencephalitis (inflammation of the brain and shells), encephalitis (inflammation of the brain).

Enough rare eye-glandular disease.It usually appears as a result of infection from a sick animal.At the same time the main symptom of listeriosis - conjunctivitis, which is accompanied by fever, intoxication, parotid and cervical lymph nodes.In addition, in patients with narrowed eye slit, swollen eyelids, vision deteriorates.This form of listeriosis occurs 1-3 months.

Sometimes chronic disease with a slightly pronounced signs.Typically, patients briefly increased body temperature, may be indigestion, catarrhal symptoms.Some patients show signs of chronic pyelonephritis.

Listeriosis in pregnant

pregnant women significantly increases the risk of listeriosis infection.This is due to the fact that during pregnancy and reduced immunity of the organism changes metabolism.Women are more difficult to tolerate all kinds of infections, including listeriosis.

The most common symptoms of listeriosis in pregnant following:

  • slightly manifested flu symptoms - fever, muscle pain and back pain, intermittent feeling of chills and fever;
  • indigestion;
  • spastic abdominal pain.

If you do not start early treatment of listeriosis in pregnant women may be serious consequences.Especially dangerous is the disease after 14 weeks of pregnancy.Sometimes listeriosis causes premature termination of pregnancy, premature birth and even stillbirth.It increases the risk of miscarriage and the procedure of analysis to listeriosis.Ultrasound examination of pregnant women provides an opportunity to see the changes in the child's organs, which can be caused by the causative agent of listeriosis.

When listeriosis in pregnant women sometimes infecting the baby during childbirth.Symptoms of congenital listeriosis occur in 1-2 weeks.The consequences for the infected child is very heavy.He may have meningitis, pneumonia, eye infections, jaundice.

Mortality in infected children is very high.Even after recovery from the residual effects of the nervous system are stored in 15-20% of children.

disease Diagnosis Diagnosis

listeriosis quite difficult.Diagnosis is based on a complex of clinical signs, laboratory tests, pathological changes, epidemiological data.

for laboratory analysis to listeriosis take blood, eye discharge, meconium (for newborn disease).The most optimal time sampling of the material in the diagnosis of listeriosis - 7-10 days of illness.All studies are conducted in the laboratory of especially dangerous infections.

most precise analysis on listeriosis is a bacteriological research method - the selection of Listeria culture.It consists of microscopic examination of smears, sowing and isolation of a pure culture of Listeria, bioassay on rabbits or white mice.The only drawback of this type of diagnosis of listeriosis is its long duration.A positive result is issued in two weeks, a final negative - within 30 days from the start of the study.

There is serological analysis method to listeriosis.However, it is not very efficient due to false positive results.

Treatment of listeriosis

Treatment of this disease requires an individual approach to each patient depending on the severity and symptoms of the disease.

most commonly used in the treatment of listeriosis tetracycline antibiotics.With eye-glandular form of the disease using special drops, ointment for the eyes.

If necessary, treatment of listeriosis include detoxification of the body, the use of fever-reducing medications and antihistamines.The doctor is required to appoint vitamins and adaptogens (preparations to facilitate the body to adapt to adverse conditions).
