It reduces the number of leukocytes in peripheral blood, especially neytrofillov and eozinofillov.
Botulism – a disease caused by, food contaminated with botulism chopsticks. Pathogen – anaerobe widely distributed in nature, a long time can be in the soil in the form of spores. Comes from the soil, from the intestines of farm animals, as well as some freshwater fish of different foods – vegetables, fruits, grains, meat and so on. Without access of oxygen, for example, preserving food, botulism bacteria begin to multiply and produce toxins, which is the strongest bacterial poison.

When propagating then the lymphatic system and partly through the bloodstream, the virus reaches the salivary glands and nerve cells of the cerebral cortex, Ammon’s horn, bulbar centers, infecting them, causing severe irreversible violations buy Endep.
The incubation period lasts from 15 to 55 days, but can sometimes be delayed up to six months or more. The disease has three phases.
1. Prodrome (the period of precursors) – lasts 1-3 days. Accompanied by an increase in temperature up to 37,2-37,3 C, depression, poor sleep, insomnia, anxiety of the patient. Pain at the site of the bite is felt, even if the wound is healed.
