Infectious and parasitic diseases

Lyme disease (lime-borreliosis)

Lyme disease (ixodal tick-borne borreliosis, systemic tick-borne borreliosis, lime-borreliosis) is a natural focal infectious disease with a transmissible mechanism of the pathogen transmission, characterized by a primary lesion of the skin, nervous system, heart, joints and a tendency to chronic course.

Treatment of leptospirosis

Treatment of leptospirosis is carried out in a hospital. Hospitalization is conducted according to epidemiological indications. The regime in the acute period is bed rest.

Diagnosis of leptospirosis

An important role in the diagnosis of leptospirosis is played by epidemics. It is necessary to take into account the profession of the patient (agricultural worker, hunter, veterinarian, deratigator), as well as contact with wild and domestic animals. It should be noted whether the patient bathed in open reservoirs, since the seeding of water by leptospira in certain regions is extremely large.

Symptoms of leptospirosis

The severe form is characterized by severe fever and unfolded symptoms of leptospirosis, and for severe form jaundice development, the appearance of signs of thrombohemorrhagic syndrome, meningitis and acute renal failure are characteristic.

What causes leptospirosis?

The genus Leptospira of the family Leptospiraceae is represented by two species: parasitic - L. Interrogans and saprophytic - L. Biflexa. Both species are divided into numerous serotypes. The latter are the main taxonomic unit that forms serological groups. The classification of leptospira is based on the constancy of their antigenic structure.

Leptospirosis

Leptospirosis (Vasiliev-Weil disease, infectious jaundice, Japanese 7-day fever, nannukai, water fever, ikterogemorragicheskaya fever, etc.) - a general term for all infections caused by bacteria of the genus Leptospira regardless of the serotype; includes infectious, or leptospiroznuyu, jaundice and canine fever.

Recurrent tick-borne typhus: causes, symptoms, diagnosis, treatment

Return typhus tick-borne (endemic recurrent typhus, tick-borne spirochetosis, tick-borne relapsing fever), zoonosis, acute natural focal disease of warm and hot climate zones, transmitted to humans by mites, characterized by multiple attacks of fever, divided by periods of apyrexia.

Treatment and prevention of recurrent typhoid fever

Treatment of recurrent typhoid fever is carried out for 7-10 days by one of the antibiotics acting on Borrelia. The drugs of choice are tetracyclines: doxycycline 100 mg twice daily or tetracycline, 0.5 g four times a day.

Diagnosis of recurrent typhoid fever

Diagnosis of recurrent typhoid fever is based to a large extent on the data of the epidemiological anamnesis - stay in the area where the typhus is recurrent typhoid. In the period of the first attack, the main symptoms are taken into account: acute onset of the disease, hyperthermia from the first hours, severe pain syndrome (headache, muscle pain), early increase and soreness of the spleen and liver, subicteric skin and sclera.

What causes recurrent typhoid fever?

The causative agent of recurrent typhoid fever is the spirochaete Borrelia recurrentis Obermeieri of the family Spirochaetaceae, the genus Borrelia, in shape resembling a threadlike spiral with 6-8 curls; has active mobility; anaerobe. Propagated by transverse division. It is well colored with aniline dyes, gram-negative. It grows on special nutrient media.
