[Provision and measures for sanitation in piglet breeding operations with latent swine dysentery].

The eradication and control of swine dysentery in breeding or farrow-to-finish herds require comprehensive knowledge about the epidemiology, pathogenesis and immunology of this typical multifactorial disease. Based upon this background information, the characteristics of chemotherapy, immunoprophylaxis and other necessary concomitant measures are described. The objectives of the eradication and control schemes should be the production of Treponema-free weaner pigs and a long-term prevention of reinfections.
