Salmonellosis farm animals registered in all countries. The disease causes significant economic losses to livestock. Thus, according to (Zaroza V. G., 1985), the incidence of animals in case of untimely events protysalmoneloznyh reaches 50–80 %, mortality — 50–70 %.
In recent years, many countries observed a significant increase in the number of salmonella outbreaks as farm animals, and people. The level of disease in humans with salmonellosis in Ukraine in recent years has not diminished: per 100,000 population in the years it ranged from 15.91–21.78 cases.
So retrospective immunological monitoring of the dynamics of antibodies to antigens of microbial cells of Salmonella in clinically ill and clinically healthy calves by spontaneous salmonella salmonella in disadvantaged on dairy farms.
Levels of antibodies to antigens of salmonellosis sticks for spontaneous salmonellosis in calves with significant growth dynamics in the first 30 days after clinical recovery of patients with salmonellosis of calves , followed by a gradual decrease in their level.
Detection of high (> 1:100) antibody titers in RA or RNIF is evidence of an active infection in the body of animals studied. Detection of antibodies to antigens of Salmonella microbial cells in RA and RNIF serum of calves with titers of 1:100 or higher is evidence of current active infection in a population of susceptible animals. The levels of antibodies in the serum of calves with active infection or salmonelonosiystva antigens S. dublin is significantly higher than the antigen S. typhimurium, indicating a longer evolutionary relationships among populations of cattle as a host, and S. dublin, like a parasite.
Both the immunological reaction — RA RNIF both integrated and independent applications objectively reflect the immune status of the host population for Salmonella.
