Abstract
It was conducted a chamber analysis of scientific trends in solving the problems of
chlamydia in pigs and focusing on the most effective methods of the disease prevention
and the treatment of animals. It has been determined that chlamydia are positioned as
bacteria and viruses, and therefore are quite common among farm animals, and poultry:
about 90 million new cases of chlamydia disease in animals, in particular pigs, are
registered in the world. Some types of chlamydia threaten the health of people and
animals, reducing the productivity of the latter. Chlamydiae are Gram-negative, obligate
intracellular bacteria with a complex developmental cycle consisting of two stages, such
as the elementary body (infectious) and the reticulum body. This determines their latency
and resistance to antibiotics and other therapeutic drugs. It has been determined that
chlamydia are similar to viruses and have the ability to cause dangerous formations in
the body of animals. Chlamydial disease in pigs manifests as conjunctivitis, pneumonia,
and pseudomembranous or necrotizing enteritis, which is confirmed by the experimental
reproduction of the infection in gnotobiotic pigs using clinical isolates. In addition,
chlamydia is associated with pericarditis, polyarthritis and polyserositis in piglets and
numerous reproductive problems such as vaginal discharge from the sow, disruption of
the sexual cycle, abortions, mummification of fetuses, the birth of weak piglets, the
increased perinatal and neonatal mortality, as well as orchitis, epididymitis and urethritis
in boars. However, for most of these diseases, the ultimate role of chlamydia is not fully
defined.
Chlamydia is considered a pathogen in pigs, chlamydia tests are not performed in
most available veterinary diagnostic laboratories. Chlamydia often occurs together with
other pathogens, and this phenomenon complicates the recovery of pigs to a certain
extent. Infection of animals with chlamydia occurs as a result of direct contact of their
mucous membranes with the causative agent of the disease. The systematic control of the
presence of chlamydia in animals of the breeding herd will prevent a decrease in their
productivity, that is, the substantial economic losses. The study of chlamydia by the
molecular genetic method (PCR) will allow to identify sick animals and carry out their
illumination, which is the most promising and will ensure the detection of sick animals.
Key words: chlamydia, infection, bacteria, animal, pig, pathogenesis, symptoms,
diagnostic methods.
