Pathobiology of the highly pathogenic avian influenza viruses H7N1 and H5N8 in different chicken breeds and role of Mx 2032 G/A polymorphism in infection outcome
(BMC, 2020-09-10)
Chickens are highly susceptible to highly pathogenic avian infuenza viruses (HPAIVs). However, the severity of infec‑
tion varies depending of the viral strain and the genetic background of the host. ...
Efficacy of recombinant Marek’s disease virus vectored vaccines with computationally optimized broadly reactive antigen (COBRA) hemagglutinin insert against genetically diverse H5 high pathogenicity avian influenza viruses
(Elsevier, 2021-03-11)
The genetic and antigenic drift associated with the high pathogenicity avian influenza (HPAI) viruses of Goose/Guangdong (Gs/GD) lineage and the emergence of vaccine-resistant field viruses underscores ...
In a warm climate, ventilation, indoor temperature and outdoor relative humidity have significant effects on Campylobacter spp. colonization in chicken broiler farms which can occur in only 2 days
(Elsevier, 2022-08-28)
A longitudinal study was conducted in five conventional broiler farms during a 2-year period to determine the dynamics of Campylobacter infection in a warm climate region (north-eastern Spain). Weekly ...
Transmission of Similar Mcr-1 Carrying Plasmids among Different Escherichia coli Lineages Isolated from Livestock and the Farmer
(MDPI, 2021-03-17)
Colistin use has mostly been stopped in human medicine, due to its toxicity. However, nowadays, it still is used as a last-resort antibiotic to treat hospital infections caused by multi-drug resistant ...

Senecavirus A (SVA) is a non-enveloped, single-stranded, positive-sense RNA
virus belonging to the Picornaviridae family. Senecavirus A is constantly
associated with outbreaks of vesicular disease in ...
The Role of Birds of Prey in West Nile Virus Epidemiology
(MDPI, 2020-09-21)
Reported human cases of West Nile virus (WNV) in Europe increased dramatically in
2018. Lineage 1 strains had been circulating in Euro-Mediterranean countries since the early 1990s.
The subsequent ...
The effects of colostrum consumption and feed restriction during marketing and transportation of male dairy beef calves: Impact on pre-transport nutritional status and on farm recovery
(Elsevier, 2023-08-23)
The aim of this study was to evaluate the effects of colostrum consumption and feed restriction on biomarkers of stress, nutritional and health status, gut functionality, and behavior in male dairy beef ...
