To explain the nature of cancer, two dominant theories have been proposed - mutational and viral. In accordance with the first cancer is the result of successive mutations of a number of genes in one cell, ie, it is based on changes that occur at the gene level.
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.
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.
Y. Pseudotuberculosis and Y. Enterocolitica do not belong to the category of especially dangerous, but they also play a significant role in human pathology.
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.
