Bacteria

Gonococci

Gonorrhea (Greek gonos - semen and rhoe - discharge) is an infectious disease of humans caused by gonococcus and characterized by inflammatory lesions mainly of the mucous membranes of the genitourinary organs.

Meningococci

Meningococci are gram-negative spherical cells with a diameter of 0.6-0.8 µm. In smears prepared from material taken from a patient, they have the shape of a coffee bean, are often located in pairs or tetrads, or randomly, often inside leukocytes - incomplete phagocytosis.

The plague pathogen

Plague (pestis) is an acute infectious disease that occurs as a hemorrhagic septicemia. In the past, the plague was a terrible scourge for humanity. Three plague pandemics are known, which took millions of human lives.

Pneumococci

A special position in the genus Streptococcus is occupied by the species S. pneumoniae, which plays a very important role in human pathology. It was discovered by L. Pasteur in 1881.

Streptococci

Streptococci belong to the Streptococcaceae family (genus Streptococcus). They were first discovered by T. Bilroth in 1874 during erysipelas; by L. Pasteur in 1878 during postpartum sepsis; isolated in pure culture in 1883 by F. Feleisen.

Staphylococci

Staphylococcus was discovered in 1878 by R. Koch and in 1880 by L. Pasteur in purulent material. L. Pasteur, having infected a rabbit, finally proved the role of staphylococcus as a causative agent of purulent inflammation.

Hemophiliacs, bacillus influenzae.

The influenza bacillus - Haemophilus influenzae - is often present on the mucous membrane of the upper respiratory tract of a healthy person.

The causative agent of tularemia

Tularemia is a primary disease of animals (rodents); in humans it occurs as an acute infectious disease with a varied clinical picture and slow recovery of working capacity.

The anthrax agent

Anthrax is an acute infectious disease of humans and animals (domestic and wild). The Russian name for the disease was given by S. S. Andrievsky in connection with a large epidemic in the Urals at the end of the 18th century. In 1788, with a heroic experiment of self-infection, he proved the identity of anthrax in humans and animals and finally confirmed its nosological independence.

The sap pathogen

Glanders is an acute infectious disease of zoonotic origin, occurring as septicopyemia in acute or chronic form with the formation of pustules, ulcers, multiple abscesses in various tissues and organs.
