Infectious and parasitic diseases

How is plague prevented?

Specific prophylaxis of plague is the annual immunization with live anti-plague vaccine of persons living in or out of epizootic foci. People who come into contact with the sick plague, their belongings, the corpses of animals, carry out emergency chemoprophylaxis.

Treatment of plague

Etiotropic therapy should be started when suspected of plague, without waiting for bacteriological confirmation of the diagnosis. It includes the use of antibacterial drugs. When studying natural strains of plague bacteria on the territory of Russia, resistance to common antimicrobial agents was not detected.

Diagnosis of the plague

Diagnosis of plague is based on clinical and epidemiological data: severe intoxication, the presence of an ulcer, bubo, severe pneumonia, hemorrhagic septicemia in persons in the natural focal zone for plague

Symptoms of the plague

The incubation period of the plague lasts from several hours to 9 days or more (an average of 2-4 days), contracting with the primary pulmonary form and extending to vaccinated or receiving preventive drugs.

Causes and pathogenesis of plague

The causative agent of plague is a small, polymorphic, fixed immobilized rod Yersinia pestis of the Enterobacteriaceae family of the genus Yersinia. Has a mucous capsule, does not form a spore. Facultative anaerobic. It is colored by bipolar aniline dyes (more intensively around the edges). Isolate rat, groundworm, gopher, flight and sandy varieties of plague bacteria.

Plague

Plague (pestis) is an acute zoonotic natural-focal infectious disease with a predominantly transmissible mechanism of transmission of the pathogen, which is characterized by intoxication, damage to the lymph nodes, skin and lungs. It is referred to especially dangerous, conventional diseases.

Treatment of yersiniosis

Consultations of other specialists are shown with prolonged subfebrility, systemic clinical manifestations, formed secondary focal forms in cases when the treatment of yersiniosis is not effective.

Diagnosis of yersiniosis

Diagnosis of yersiniosis is complex in any form and is based on characteristic symptoms and laboratory diagnosis. Specific laboratory diagnostics of yersiniosis includes bacteriological, immunological and serological methods.

What causes iersiniosis?

The causative agent of yersiniosis is the Gram-negative bacillus Yersinia enterocolitica of the Enterobacteriaceae family. It is a heterotrophic facultative-anaerobic microorganism with psychrophilic and oligotrophic properties. Rastetna "hungry" environments and on media with a depleted composition.

Yersiniosis

Yersiniosis (syn: intestinal yersiniosis, English Yersiniosis) - zoophilic sapronosis with fecal-oral mechanism of transmission of the pathogen. It is characterized by the development of intoxication syndrome, the primary lesion of the gastrointestinal tract, in the generalized form - polyorganic lesion. Has a tendency to exacerbations, relapses and chronization.
