Evaluation of the transcriptional status of host cytokines and viral genes in the trachea of vaccinated and non-vaccinated chickens after challenge with the infectious laryngotracheitis virus
(Taylor & Francis, 2016)Infectious laryngotracheitis is a highly contagious disease of chickens responsible for significant economic losses for the poultry industry worldwide. The disease is caused by Gallid herpesvirus-1 (GaHV-1) commonly known ... -
Molecular and serological detection of Babesia bovis- and Babesia bigemina-infection in bovines and water buffaloes raised jointly in an endemic field
(2016-01)Babesia bovis and Babesia bigemina are causative agents of bovine babesiosis, a tick-borne disease of cattle in tropical and subtropical regions. Babesia spp. infection adversely affects cattle health and can be fatal ... -
Zearalenone content in animal fodder samples in relation to weather conditions in Colonia Benítez, northeastern Argentina
(2016-05)The northeast of Argentina is a livestock production area. Generally cattle in this area feed on grasslands and improved pastures, but their food is often supplemented with grains, protein sources and reserves in the form ... -
The intranasal vaccination of pregnant dams with Intimin and EspBconfers protection in neonatal mice from Escherichia coli (EHEC)O157:H7 infection
(2016-05)Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is responsible for intestinal disease and hemolytic uremic syndrome (HUS), a serious systemic complication which particularly affects children. In this study, we evaluated ... -
Molecular detection of Sarcocystis aucheniae in the blood of llamas from Argentina
(2016-09)Sarcocystis aucheniae are apicomplexan protozoa that infect South American camelids (SACs), giving rise to macroscopic cysts similar to rice grains in skeletal muscles. Visual detection of macrocysts in slaughtered animals ... -
Molecular detection and phylogenetic analysis of Hepatozoon spp. in questing Ixodes ricinus ticks and rodents from Slovakia and Czech Republic
(2016-10)By amplification and sequencing of 18S rRNA gene fragments, Hepatozoon spp. DNA was detected in 0.08 % (4/5057) and 0.04 % (1/2473) of questing Ixodes ricinus ticks from Slovakia and Czech Republic, respectively. Hepatozoon ... -
Plant-based vaccine for livestock : key points to unleash platform translation in developing countries
(2016-12)Ten years ago the first plant-based vaccine was licensed (DowAgrosciences). It was only 20 years after the first report of a recombinant protein obtained through plant transformation technology. Back then, this vaccine was ... -
Human brucellosis and adverse pregnancy outcomes
(Springer, 2016-12)Purpose of Review Brucellosis is a neglected, zoonotic disease of nearly worldwide distribution. Despite brucellosis being recognized as a reproductive disease in animals, it has been historically known as a flu-like ... -
Impact of chestnut and quebracho tannins on rumen microbiota of bovines
(Hindawi, 2017)The use of phytogenic dietary additives is being evaluated as a means to improve animal productivity. The effect of tannins seems to be the influence not only directly on the digestive process through binding of dietary ... -
Intrinsic and extrinsic factors related to pathogen infection in wild small mammals in intensive milk cattle and swine production systems
(2017)Background: Understanding the ecological processes that are involved in the transmission of zoonotic pathogens by small mammals may aid adequate and effective management measures. Few attempts have been made to analyze ... -
Serology and protein electrophoresis for evidence of exposure to 12 mink pathogens in free-ranging American mink (Neovison vison) in Argentina
(2017)Background: Basic pathologic characteristics for farmed minks were previously reported worldwide. However, its status in the wild has not been studied in detail. Objective: Serology and electrophoresis were carried out ... -
Resistencia a los antihelmínticos en bovinos del nordeste de Corrientes (Argentina) = Resistance to antiparasitics in cattle from northeast of Corrientes (Argentina)
(Universidad Nacional del Nordeste. Facultad de Ciencias Veterinarias, 2017)El objetivo del trabajo fue determinar la prevalencia de la resistencia a los antiparasitarios contra los nematodes gastrointestinales de bovinos en el nordeste de Corrientes. El área de estudio comprendió 4 establecimientos ... -
Immune response in calves vaccinated with type three secretion system antigens and shiga toxin 2B subunit of Escherichia coli O157:H7
(2017-01-03)Ruminants are the primary reservoir of Shiga-toxin producing Escherichia coli (STEC) O157:H7 and the main source of infection for humans. The aim of this study was to assess the immunogenic properties of a candidate vaccine ... -
First isolation of Leptospira borgpetersenii from Fetuses of Wild boars (Sus scrofa)
(2017-02-07)Leptospirosis is a worldwide zoonose and is endemic in many countries. This zoonosis is maintained in nature by chronic renal infection of carrier animals, being rodents and other small mammals the most important reservoirs. ... -
Modulation of host plant immunity by Tobamovirus proteins
(2017-03)To establish successful infection, plant viruses produce profound alterations of host physiology, disturbing unrelated endogenous processes and contributing to the development of disease. In tobamoviruses, emerging evidence ... -
New scenarios for brucella suis and brucella melitensis
(Springer, 2017-03)Purpose of Review: We pretend to highlight the most important advances reached in the last few years in the biology of Brucella suis and Brucella melitensis and focus attention on new tools for the comprehension, prevention ... -
