Variations in association of nasal microbiota with virulent and non-virulent strains of Glaesserella (Haemophilus) parasuis in weaning piglets
(BMC, 2020-02-03)
Glaesserella (formerly Haemophilus) parasuis causes Glässer's disease, which results in high economic loss in the swine industry. To understand the polymicrobial interactions of G. parasuis and the nasal ...
Evolution of Swine Influenza Virus H3N2 in Vaccinated and Nonvaccinated Pigs after Previous Natural H1N1 Infection
(MDPI, 2022-09-10)
Swine influenza viruses (SIV) produce a highly contagious and worldwide distributed
disease that can cause important economic losses to the pig industry. Currently, this virus is endemic
in farms and, ...
Comparison of the pathological outcome and disease progression of two Mycobacterium caprae experimental challenge models in goats: endobronchial inoculation vs. intranasal nebulization
(Frontiers Media, 2023-08-11)
Background: Goats are natural hosts of tuberculosis (TB) and are a valid animal model to test new vaccines and treatments to control this disease. In this study, a new experimental model of TB in goats ...
Expression analysis of porcine miR-33a/b in liver, adipose tissue and muscle and its potential role in fatty acid metabolism
(Public Library of Science, 2021-01-26)
mir-33a and mir-33b are co-transcribed with the SREBF2 and SREBF1 transcription factors, respectively. The main role of SREBF1 is the regulation of genes involved in fatty acid metabolism, while SREBF2 ...
Porcine circovirus 2 (PCV2) population study in experimentally infected pigs developing PCV2-systemic disease or a subclinical infection
(Nature Research, 2020-10-20)
Porcine circovirus 2 (PCV2) is a single stranded DNA virus with one of the highest mutation rates among DNA viruses. This ability allows it to generate a cloud of mutants constantly providing new ...
Commercial feed containing porcine plasma spiked with African swine fever virus is not infective in pigs when administered for 14 consecutive days
(Public Library of Science, 2020-07-22)
The objective of this study was to determine if commercially collected liquid porcine plasma contaminated with African swine fever virus (ASFV) and fed for 14 consecutive days would infect pigs. ...
Hydrocarbon-Contaminated Sites: Is There Something More Than Exophiala xenobiotica? New Insights into Black Fungal Diversity Using the Long Cold Incubation Method
(MDPI, 2021-09-29)
Human-made hydrocarbon-rich environments are important reservoirs of microorganisms with specific degrading abilities and pathogenic potential. In particular, black fungi are of great interest, but their ...
Type I and III IFNs produced by the nasal epithelia and dimmed inflammation are features of alpacas resolving MERS-CoV infection
(Public Library of Science, 2021-05-24)
While MERS-CoV (Middle East respiratory syndrome Coronavirus) provokes a lethal disease in humans, camelids, the main virus reservoir, are asymptomatic carriers, suggesting a crucial role for innate ...
Genetic parameters and associated genomic regions for global immunocompetence and other health-related traits in pigs
(Nature Research, 2020-10-28)
The inclusion of health-related traits, or functionally associated genetic markers, in pig breeding programs could contribute to produce more robust and disease resistant animals. The aim of the present ...
Effect of harvesting age and size reduction in the performance of anaerobic digestion of Pennisetum grass
(MDPI, 2020-11-06)
In the rural zones of Latin American and Caribbean developing countries, the poorest households rely on traditional fuels such as firewood to meet their daily cooking needs. Many of those countries are ...
