Infectious and parasitic diseases

Viral hepatitis A

Viral hepatitis A (infectious hepatitis, epidemic hepatitis, Botkin's disease) is an acute viral disease of humans with a fecal-oral mechanism of pathogen transmission. It is characterized by liver inflammation, a cyclic benign course, and may be accompanied by jaundice.

Mycoplasmosis (mycoplasmal infection)

Mycoplasmosis (mycoplasma infection) is an anthropozoonotic infectious disease caused by bacteria of the genera Mycoplasma and Ureaplasma, characterized by damage to various organs and systems (respiratory organs, genitourinary, nervous and other systems).

Ornithosis (psittacosis)

Ornithosis (ornithosis; syn. psittacosis) is a zoonotic natural-anthropurgic infectious disease with an aerosol mechanism of transmission of the pathogen, characterized by fever, intoxication, damage to the lungs, nervous system, and hepatosplenic syndrome.

Cat scratch disease: causes, symptoms, diagnosis, treatment

Cat scratch disease (felinosis, benign lymphoreticulosis) is an acute zoonotic infectious disease with contact and transmission mechanisms of the pathogen, characterized by lymphadenitis, primary affect in the form of a suppurating papule, in some cases - conjunctivitis, angiomatosis and liver damage.

Ehrlichioses

Ehrlichiosis is a group of acute zoonotic, mainly transmissible, infectious diseases characterized by polymorphism of clinical manifestations.

Q fever - Treatment and prevention

Treatment of Q fever includes etiotropic, pathogenetic and symptomatic therapy. For etiotropic treatment, antibiotics of the tetracycline group and chloramphenicol (standard treatment) are used. Tetracycline is prescribed in the first days of the disease (until the temperature is normalized) at 0.4-0.5 g four times a day, then 0.3-0.4 g four times a day for another 5-7 days, doxycycline - 200 mg/day, chloramphenicol - 0.5 g four times a day.

Q fever - Diagnosis

The basis of laboratory diagnostics of Q fever is serological methods: RA, RSK, RNIF, the results of which are analyzed taking into account the phase variations of coxiella, which allows differentiating between patients and those who have recovered (standard diagnostics).

Q fever - Symptoms

Unlike other rickettsioses, Q fever is characterized by a pronounced polymorphism of symptoms, which depends on the mechanism of transmission of the pathogen, the infecting dose of rickettsia and the state of the macroorganism.

Q fever - Causes and pathogenesis

The cause of Q fever is Coxiella burnetii, a small polymorphic gram-negative non-motile microorganism measuring 200-500 nm, capable of forming an L-form.

Q fever

Q fever (Latin: Q-febris, ricketsiosis Q rickettsiosis, coxiellosis, pneumorickettsiosis, slaughterhouse fever, pneumonic typhus. Derrick-Burnett disease. Balkan flu, Central Asian fever) is an acute natural focal zoonotic rickettsiosis with various mechanisms of transmission of the pathogen, characterized by the development of widespread reticuloendotheliosis.
