Evaluation of immune responses of stabilised SAT2 antigens of foot-and-mouth disease in cattle
(2017)Foot-and-mouth disease (FMD) vaccines with improved stability and less reliant on a cold-chain are needed to improve the longevity of immune responses elicited in animals. This is especially so for serotypes O and SAT2 ... -
Dendrimeric peptides can confer protection against foot-and-mouth disease virus in cattle
(2017-09)Foot-and-mouth disease virus (FMDV) causes a highly contagious disease in cloven-hoofed animals. A synthetic vaccine candidate consisting of dendrimeric peptides harbouring two copies of a B-epitope [VP1(136–154)] linked ... -
Neutralizing monoclonal antibodies to fight HIV-1 : on the threshold of success
(2017)Anti-human immunodeficiency virus type-1 (anti-HIV-1) neutralizing monoclonal antibodies are broadening the spectrum of pre- and post-exposure treatment against HIV-1. A better understanding of how these antibodies develop ... -
Serologic evidence of HoBi-like virus circulation in Argentinean water buffalo
(2017-11)HoBi-like pestiviruses (also known as bovine viral diarrhea virus 3) have been sporadically reported from naturally infected cattle in Brazil, Asia, and Europe. Although HoBi-like viruses seem to be endemic in Brazilian ... -
Molecular characterization of equine rotavirus group A detected in Argentinean foals during 2009–2014
(2017-12)Equine rotavirus group A (RVA) has been detected in several countries worldwide since its first detection in 1975. Currently, equine RVA is considered the major cause of dehydrating diarrhea in foals younger than 3 months, ... -
Apicomplexan profilins in vaccine development applied to bovine neosporosis
(2017-12)Neospora caninum, an intracellular protozoan parasite from the phylum Apicomplexa, is the etiologic agent of neosporosis, a disease considered as a major cause of reproductive loss in cattle and neuromuscular disease in ... -
Evidence of natural interspecific recombinant viruses between bovine alphaherpesviruses 1 and 5
(2017-10)Closely related bovine alphaherpesviruses 1 (BoHV-1) and 5 (BoHV-5) co-circulate in certain countries, rendering cattle co-infection possible. This is a prerequisite for BoHV recombination. Here, we report the first ... -
Immunization with Neospora caninum profilin induces limited protection and a regulatory T-cell response in mice
(2016)Profilins are actin-binding proteins that regulate the polymerization of actin filaments. In apicomplexan parasites, they are essential for invasion. Profilins also trigger the immune response of the host by activating ... -
Development and evaluation of a new lateral flow assay for simultaneous detection of antibodies against African horse sickness and equine infectious anemia viruses
(2016)African horse sickness (AHS) and equine infectious anemia (EIA) are both notifiable equid specific diseases that may present similar clinical signs. Considering the increased global movement of horses and equine products ... -
Fusion of foreign T-cell epitopes and addition of TLR agonists enhance immunity against Neospora caninum profilin in cattle
(2016)We demonstrated recently that immunization with recombinant Neospora caninum profilin (rNcPRO) induces limited protection and a regulatory T-cell response in mice. The aim of this study was to evaluate the immune response ... -
Construction and manipulation of a full-length infectious bacterial artificial chromosome clone of equine herpesvirus type 3 (EHV-3)
(2017-01)Equine herpesvirus type 3 (EHV-3) is the causal agent of equine coital exanthema, a disease characterizedby pox-like lesions on the penis of stallions and the vulva of mares. Although the complete genomicsequence of EHV-3 ... -
Isolation and molecular characterization of Clostridium perfringens from healthy Merino lambs in Patagonia region, Argentina
(2016)The presence and molecular characterization of Clostridium perfringens in healthy Merino lambs over a six-month period was investigated in this study. Overall, a high prevalence of C. perfringens was detected, even in ... -
Development of RT-qPCR assays for the specific identification of two major genotypes of avian infectious bronchitis virus
(2016)Infectious bronchitis virus (Gammacoronavirus, Coronaviridae) is a genetically variable RNA virus (27.6kb) that causes one of the most persistent respiratory disease in poultry. The virus is classified in genotypes with ... -
Epidemiological and virological findings during multiple outbreaks of equine influenza in South America in 2012
(2016-01)Background: In 2012, equine influenza (EI) virus was confirmed as the cause of outbreaks of respiratory disease in horses throughout South America. In Uruguay and Argentina, hundreds of vaccinated thoroughbred horses in ... -
Antiviral agents against equid alphaherpesviruses : current status and perspectives
(2016)Equid herpesvirus infections cause respiratory, neurological and reproductive syndromes. Despite preventive and control measures and the availability of vaccines and immunostimulants, herpesvirus infections still constitute ... -
Molecular detection of bovine Noroviruses in Argentinean dairy calves : circulation of a tentative new genotype
(2016)Bovine noroviruses are enteric pathogens detected in fecal samples of both diarrheic and non-diarrheic calves from several countries worldwide. However, epidemiological information regarding bovine noroviruses is still ... -
Bovine leukemia virus small noncoding RNAs are functional elements that regulate replication and contribute to oncogenesis in vivo
(2016-04)Retroviruses are not expected to encode miRNAs because of the potential problem of self-cleavage of their genomic RNAs. This assumption has recently been challenged by experiments showing that bovine leukemia virus (BLV) ... -
Evaluation of serological response to foot-and-mouth disease vaccination in BLV infected cows
(2016)Bovine Leukemia Virus (BLV) produces disorders on the immune system in naturally infected animals, which may counteract the development of immunity after vaccination. The aim of this study was to investigate whether healthy ... -
Short communication: Relationship between the level of bovine leukemia virus antibody and provirus in blood and milk of cows from a naturally infected herd
(2016)We explored the relationship between the level of bovine leukemia virus antibodies and provirus load during natural infection. For that purpose, a set of 50 blood and milk paired samples were analyzed for the presence of ... -
Cattle are a potential reservoir of bubaline herpesvirus 1 (BuHV1)
(2016)In the present work, controlled experimental infection and transmission studies in domestic cattle (Bos taurus) and water buffaloes (Bubalus bubalis) were carried out to study the in vivo behaviour of bubaline herpesvirus ...
