Abstract:
Experiments on noninbred white mice have revealed that in the animals infected with S. moscow secondary immunodeficiency develops, which is manifested by a significant decrease in the activity of the bactericidal system of peripheral blood granular leukocytes. Simultaneously, the content of myeloperoxidase in the blood neutrophils of infected mice decreases 1.4 times and the content of lysozyme in these neutrophils decreases 2 times. Such changes are the consequence of an increase in the secretory activity of cells, occurring in the process of the development of Salmonella infection.

01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
