Maintaining reproductive health is an urgent task in intensive livestock farming. The study of the influence of pathogens of the Mycoplasmataceae family on the microecology and protective properties of the vagina is of particular interest. The studies were carried out on non-pregnant cows 3–4 years old. Was formed 2 groups of 8 animals each. The first group is healthy cows in which the PCR test for Mycoplasma spp. was negative. The second group - cows with a positive PCR test and serological identification of M. bovigenitalium, without pronounced clinical signs of vaginitis. In both groups of animals, vaginal secretions were collected from the vaginal wall using a special spoon. In secret, by the method of radial immunodiffusion in a gel according to Mancini, the content of immunoglobulins of classes Ig G, Ig M, Ig A and secretory immunoglobulin A (sIgA) was determined, as well as the activity of lysozyme - by the nephelometric method. The study showed that the content of Ig G and the total content of immunoglobulins in the vaginal secretion in healthy cows and cows with mycoplasmosis did not have significant differences. The concentration of Ig A in cows with mycoplasmosis was 0.018±0.001 g/l, which was 25% less than in healthy cows, but it turned out to be insignificant (P > 0.05). The content of Ig M and sIgA in secretion in healthy cows was 0.039±0.002 and 0.067±0.005 g/l, while in cows with mycoplasmosis it significantly increased by 38.5 and 43%, respectively. The activity of lysozyme in the secretion of healthy cows was 11.71±0.41%, while in infected cows it decreased by 2 times. With genital mycoplasmosis in cows, a quantitative redistribution of immunoglobulin classes and a decrease in lysozyme activity are observed in the vaginal secretion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
