Abstract

Paratuberkuloza je kronična bolezen prebavil. Povzročitelj paratuberkuloze je bakterija Mycobacterium avium subsp. paratuberculosis. V čredi krav molznic se živali običajno okužijo že takoj po rojstvu, klinični znaki se lahko pojavijo šele po 2 ali več letih. Glavni način prenosa bolezni je po fekalno-oralni poti, 20 do 40 % zarodkov pa se lahko z bakterijo okuži že v maternici. Najbolj očitni klinični znaki pri kravah molznicah so driska in pretirano hujšanje, kljub normalnemu apetitu, lahko se pojavijo tudi edemi ventralnih delov telesa. Bolezen povzroča velike gospodarske izgube zaradi manjše prireje mleka, slabše plodnosti, pojava sekundarnih bolezni (npr. mastitis) ter predčasne izločitve živali. Paratuberkuloza je razširjena po celem svetu, trenutno na trgu ni učinkovitih zdravil, zato spada med neozdravljive bolezni. Bistvenega pomena je zgodnja diagnoza, nadzor in preprečevanje širjenja bolezni. Nekatere države po svetu imajo narejene programe za nadzor paratuberkuloze, katerih cilj je preprečitev širjenja bolezni ali popolno izkoreninjenje. Bistvenega pomena je izvajanje biovarnosti in nakup živali iz rej prostih te bolezni. V Sloveniji trenutno nimamo programa za nadzor bolezni. Točnih podatkov o razširjenosti bolezni ni, saj je veliko živali v subklinični fazi brez znakov bolezni. Poznavanje paratuberkuloze je med slovenskimi kmeti zelo slabo.

Secondary title: Paratuberculosis in dairy herds
Secondary abstract: Paratuberculosis in chronic gastrointestinal disease. The causative agent of paratuberculosis is the bacterium Mycobacterium avium subsp. paratuberculosis. In a dairy herd, animals usually become infected immediately after birth, and clinical signs may not appear for 2 or more years. The disease is transmitted mainly by the fecal-oral route, and 20 % to 40 % of embryos may become infected with the bacterium in utero. The most obvious clinical signs in dairy cows are diarrhea and excessive weight loss, despite normal appetite; edema of ventral body parts may also occur. The disease causes significant economic losses through reduced milk production, poorer fertility, the occurrence of secondary diseases (e.g., mastitis), and premature culling of animals. Paratuberculosis is prevalent worldwide, and currently there are no effective treatments, so it is classified as an incurable disease. Early diagnosis, control, and prevention of the spread of the disease are critical. Some countries around the world have implemented programs to control paratuberculosis with the goal of preventing the spread of the disease or eradicating it completely. The implementation of biosecurity measures and the purchase of animals from disease-free herds are of utmost importance. Currently, there is no disease control program in Slovenia. Accurate data on the prevalence of the disease are not available, as many animals are in a subclinical phase without signs of disease. Knowledge about paratuberculosis is very low among Slovenian farmers.
