Infectious and parasitic diseases

Symptoms of recurrent typhoid fever

Symptoms of recurrent typhoid fever are the basis for clinical classification, which provides for the isolation of aborted, mild, moderate, severe forms of vesicular recurrent typhus. The height and duration of fever, the severity of intoxication, and the intensity of hemodynamic disorders are considered criteria of severity.

Lice relapsing fever

Recurrent typhus vshny - anthroponosis, transmitted by lice, is manifested by intoxication, an increase in the spleen and liver, alternating 2-3 or more febrile seizures with febrile intervals.

Treatment and prevention of legionellosis

When suspected of legionnaires' disease as an etiotropic treatment, erythromycin is used in a daily dose of 2-4 g daily for 2-3 nel or other drugs from the group of macrolides (clarithromycin, azithromycin, spiromycin).

Diagnostics of the legionellosis

Verification of the diagnosis of legionellosis is based on the isolation of the culture of L. Pneumophilla from blood, sputum, rinsing water of the bronchi, pleural fluid. Serological diagnosis is carried out using the methods of RIF and ELISA. Diagnostic value is the study of paired sera in the dynamics of the disease. Diagnostic titer for a single serum 1: 128 study. Apply genodiagnostics using the PCR method.

Legionellosis symptoms

Symptoms of legionellosis are characterized by a wide spectrum. Infectious process can occur subclinically, asymptomatically (according to some data, more than 20% of older persons are seropositive).

Causes and pathogenesis of legionellosis

Legionellosis is common everywhere. The disease is recorded both in the form of outbreaks and sporadic cases on all continents of the globe. According to some data, the proportion of legionella in the etiological structure of pneumonia is 10%, and among atypical pneumonia - about 25%. Carrying out pathogens in birds, rodents, arthropods is not established.

Legionellosis

Legionellosis (Pittsburgh pneumonia, Pontiac fever, Fort-Bragg fever) is a group of diseases caused by bacteria of the genus Legionella, with an aerosol mechanism of transmission of the pathogen, characterized by fever, intoxication, respiratory infection

Treatment of Hemophilus Infections

Pathogenetic treatment of hemophilic infection is prescribed, based on clinical indications, and carried out according to general rules. With meningitis, dehydration therapy is indicated (furosemide, acetazolamide at average therapeutic doses, dexamethasone at a dose of 0.5 g / kg per day intravenously or intramuscularly).

Diagnosis of Haemophilus Infections

Clinical diagnosis of any form of Hib infection, except for epiglottitis, is indicative, since Hib is its most frequent pathogen. The diagnosis of Hib infection is established on the basis of the isolation of the pathogen culture and culture from pathological secrets (cerebrospinal fluid, pus, pleural effusion, sputum, swabs from the nasopharynx).

Causes and pathogenesis of hemophilic infection

The causative agent of hemophilic infection is the bacterium Haemophilus influenzae (H. Influenzae, syn. - Pfeiffer's wand). Hemophilic rod of the genus Haemophilus (family Pasteurellaceae) - small coccobacillus, can have a polysaccharide capsule.
