Babesia bovis AMA-1, MSA-2c and RAP-1 contain conserved B and T-cell epitopes, which generate neutralizing antibodies and a long-lasting Th1 immune response in vaccinated cattle
(Elsevier, 2022-02)Vaccines against bovine babesiosis must, ideally, induce a humoral immune response characterized by neutralizing antibodies against conserved epitopes and a cellular Th1 immune response. In Babesia bovis, proteins such as ... -
Unraveling the complexity of the rhomboid serine protease 4 family of Babesia bovis using bioinformatics and experimental studies
(MDPI, 2022-03)Babesia bovis, a tick-transmitted apicomplexan protozoon, infects cattle in tropical and subtropical regions around the world. In the apicomplexans Toxoplasma gondii and Plasmodium falciparum, rhomboid serine protease 4 ... -
Llama and sheep ruminal fluid digestive capacity by in vitro gas production technique
(Wiley, 2022-03)BACKGROUND: The in vitro gas production technique has been used to evaluate forage fermentation kinetics. However, individual and animal species variation can change fermentation patterns due to differences in ruminal ... -
Estudio comparativo de la gastroenteritis verminosa de los bovinos entre un pastoreo a cielo abierto y un sistema silvopastoril en el nordeste de Corrientes (Argentina) = Comparative study of bovine verminous gastroenteritis between open grazing and a silvopastoral system in northeastern Corrientes (Argentina)
(Brazilian Journals Publicações de Periódicos e Editora, 2022-04)La gastroenteritis verminosa de los bovinos es una enfermedad parasitaria producida por un complejo de nematodos gastrointestinales, ampliamente distribuidos a nivel mundial, especialmente en aquellas regiones donde los ... -
Assessment of an Aujeszky’s disease control strategy in a highly prevalent pig farm based on systematic vaccination with an inactivated gE-negative marker vaccine
(Frontiers Media, 2022-04)Aujeszky's disease (AD) is endemic in Argentina. In 2016, an inactivated gE- negative marker Bartha K61 vaccine (AUSKIPRA® BK) was launched for use, making Argentina the only country to carry out a control strategy plan ... -
International interlaboratory validation of a nested PCR for molecular detection of Babesia bovis and Babesia bigemina, causative agents of bovine babesiosis
(Elsevier, 2022-04)Babesia bovis and B. bigemina are tick-transmitted parasites causing bovine babesiosis, characterized by significant morbidity and mortality leading to economic losses to the livestock industry in tropical and subtropical ... -
Molecular detection and differentiation of arthropod, fungal, protozoan, bacterial and viral pathogens of honeybees
(MDPI, 2022-05)The honeybee Apis mellifera is highly appreciated worldwide because of its products, but also as it is a pollinator of crops and wild plants. The beehive is vulnerable to infections due to arthropods, fungi, protozoa, ... -
Comparative review of brucellosis in small domestic ruminants
(Frontiers Media, 2022-05)Brucella melitensis and Brucella ovis are the primary etiological agents of brucellosis in small domestic ruminants. B. melitensis was first isolated in 1887 by David Bruce in Malta Island from spleens of four soldiers, ... -
