The genus Pseudomonas belongs to the family Pseudomonadaceae (class Gammaproteobacteria, type Proteobacteria) and contains more than 20 species. Some of them are natural inhabitants of soil and water and therefore play a huge role in the circulation of substances in nature.
The genus Acinetobacter (6 species) includes gram-negative rods, usually very short and rounded, their dimensions in the logarithmic growth phase are 1.0-1.5 x 1.5-2.5 μm.
The genus Kingella includes 3 species, a typical species of K. Kingae. Cells are coccoid or short sticks with rectangular ends, 0.5-0.8 microns in size, i.e., smaller than most Moraxelles.
According to WHO, cholera is a disease characterized by acute severe dehydrating diarrhea with feces in the form of rice broth resulting from infection with Vibrio cholerae.
Dysentery - an infectious disease characterized by general intoxication of the body, diarrhea and a peculiar lesion of the mucous membrane of the large intestine.
An important role in the etiology of food poisoning is played by Bacillus cereus. B. Cereus - Gram-positive, non-capsule sticks with a size of 1.0-1.2 x 3-5 microns, mobile (peritrichia) or immobile.
Typhoid fever is a serious acute infectious disease characterized by deep general intoxication, bacteremia and specific damage to the lymphatic apparatus of the small intestine
The genus Moraxella includes gram-negative bacteria, usually in the form of very short rounded rods with typical sizes of 1.0-1.5 x 1.5-2.5 μm, often acquiring the form of cocci, located mainly in pairs or short chains.
