Mycobacterium avium subesp. paratuberculosis (MAP) es el agente etiológico de la paratuberculosis o enfermedad de Johne (JD), una enteritis crónica que afecta al ganado y otras especies animales y que se ha relacionado con la enfermedad de Crohn, una enfermedad intestinal inflamatoria crónica en humanos. MAP podría resistir las condiciones de pasteurización y se ha […]

Coccidiosis is an intestinal infection caused by protozoans of the genus Eimeria. When the disease occurs in winter, it is known as winter coccidiosis. In July 2021, two calves were referred to INTA-Salta SDVE to determine the cause of death. These animals belonged to a herd that had shown clinical signs, such as bloody diarrhea, […]

Biodiversity in forage legumes adapted to semiarid-arid conditions is scarce. In the Pampa-Patagonia transitional region of Argentina (PTRA), the annual rainfall is 440 mm with annual evapotranspiration of 1690 mm. Only Vicia villosa Roth shows agronomic adaptation to such an environment. Dry matter production of 19 selected legume species was compared to V. villosa (cv. […]

In ruminants, polymorphisms in microsatellites at 3´untranslated region (3´ UTR) of the SLC11A1 gene were associated with natural resistance to Brucella spp. and Mycobacterium spp. infection, but its relevance to prevent brucellosis is controversial in cattle. The aim of this study was to re-evaluate the role of these polymorphisms in the outcome of Brucella abortus […]

Dipsacus fullonum L. (common teasel) is a short-lived perennial plant that has become an invasive weed in Argentina and many other countries. It reduces native species diversity and forage production in natural protected areas and grasslands. Reproduction is only through seeds. Field surveys were carried out to determine reproductive potential under natural populations growing in […]

Diseases of the dairy herd negatively affect the period of economic use of animals, the volume of milk production and its quality. In this regard, early diagnosis of diseases and their causes will reduce the incidence of dairy herds and prevent economic losses. The research of the state of udder teats in cows during lactation […]
