Heterologous Systemic Prime–Intranasal Boosting Using a Spore SARS-CoV-2 Vaccine Confers Mucosal Immunity and Cross-Reactive Antibodies in Mice as well as Protection in Hamsters
(MDPI, 2022-11-10)
Background: Current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines are administered systemically and typically result in poor immunogenicity at the mucosa. As a result, vaccination ...
Multisystemic lymphoplasmacytic inflammation associated with PCV-3 in wasting pigs
(Wiley, 2021-07-30)
Porcine circovirus 3 (PCV-3) has been detected in diseased and healthy pigs of different ages. Several reports have associated the agent with reproductive failure and mummified and stillborn piglets. ...
Porcine circovirus 2 (PCV-2) genetic variability under natural infection scenario reveals a complex network of viral quasispecies
(Nature Research, 2018-10-19)
Porcine circovirus 2 (PCV-2) is a virus characterized by a high evolutionary rate, promoting the potential
emergence of diferent genotypes and strains. Despite the likely relevance in the emergence of ...
Analysis of the genetic diversity and mRNA expression level in porcine reproductive and respiratory syndrome virus vaccinated pigs that developed short or long viremias after challenge
(BioMed Central, 2018-02-15)
Porcine reproductive and respiratory syndrome virus (PRRSv) infection alters the host’s cellular and humoral immune
response. Immunity against PRRSv is multigenic and vary between individuals. The aim ...
Detection of SARS-CoV-2 in a cat owned by a COVID-19−affected patient in Spain
(National Academy of Sciences, 2020-09-18)
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of COVID-19, is considered a zoonotic pathogen mainly transmitted human to human. Few reports indicate that pets may ...
Diversity of influenza A viruses retrieved from respiratory disease outbreaks and subclinically infected herds in Spain (2017-2019)
(Wiley, 2020-07-03)
The present study was aimed to assess the diversity of influenza A viruses (IAV) circulating in pig farms in the Iberian Peninsula. The study included two different situations: farms suffering respiratory ...
A prospective longitudinal study of risk factors associated with cattle lameness in southern Alberta feedlots
(Canadian Science Publishing, 2021-03-15)
The objectives of this study were to determine the incidence proportion of lameness in feedlot cattle and the associated risk factors. Lameness was studied in two southern Alberta feedlots over a 2 yr ...
Feeding pasteurized waste milk to preweaned dairy calves changes fecal and upper respiratory tract microbiota
(Frontiers Media, 2019-06-06)
In the present study bacterial communities from both, the gastrointestinal and respiratory tract of pre-weaned dairy calves fed two different milk-feeding programs were characterized using 16S rRNA gene ...
Cross-protection against African swine fever virus upon intranasal vaccination is associated with an adaptive-innate immune crosstalk
(Public Library of Science, 2022-11-09)
African swine fever virus (ASFV) is causing a worldwide pandemic affecting the porcine industry and leading to important global economic consequences. The virus causes a highly lethal hemorrhagic disease ...
Early and Solid Protection Afforded by the Thiverval Vaccine Provides Novel Vaccination Alternatives Against Classical Swine Fever Virus
(MDPI, 2021-05-06)
Classical swine fever virus (CSFV) remains a challenge for the porcine industry. Inefficient
vaccination programs in some endemic areas may have contributed to the emergence of low and
moderate virulence ...
