title: Trueperella pyogenes infections in swine: clinical course and pathology.
abstract: Trueperella pyogenes is an opportunistic pathogen causing purulent infections in pigs and other animal species. T. pyogenes infections in pigs are local and/or generalized depending on the immune status of the animals, their individual susceptibility and environmental factors. The occurrence of these infections on pig farms causes substantial economic losses in breeding and rearing. In sows from the breeding herd, the disease leads to infertility, embryonic death, abortion, and disorders of the menstrual cycle and lactation. Mastitis is the major cause of losses in piglets. Disorders of the musculoskeletal system, including inflammatory polyarthritis, fractures and degenerative joint disease results in the culling of animals with high breeding value. In other technological groups, multi-organ inflammations and movement disorders dominate, leading to a reduction of the slaughter value and elimination of pigs from breeding. Understanding of the clinical and pathological aspects of T. pyogenes infections in pigs will enable the development of effective methods of combating this disease on pig farms.
