As has been established in chlamydial animals chlamydiae are localized also in the central nervous system - in the brain and spinal cord. On the basis of the investigations of the brain and spinal cord applying the immunofluorescence method chlamydia have been found in cattle, pigs, horses, sheep, rabbits, guinea-pigs, dogs, cats, arctic foxes, caged minks, white rat, mice, hens, pigeons, elks, wild boars, pine martens. Chlamydiosis has been detected also in perintal and older calves as well as in full-grown cows. Chlamydial infection was most often found in perinatal calves which died before the 7th day of life. Cerebral investigations had revealed chlamydiosis also in pigs which died at different ages, in most cases perinatally - stillborn and 1...3-day-old piglets - 84.2 per cent. In piglets which died at an older age and pigs which died at the age of 1...6 month the incidence of chlamydial infection was lower, but still noticeably high -41.2...55.6 per cent. Chlamydiae were also found in the samples taken from the brain and spinal cord of butchered pigs in abattoirs and carcasses in meat markets
