Comparing responses to different selenium sources and dosages in laying hens.
selenite at 0.1, 0.3, or 0.5 mg/kg of Se. The feeding trial lasted 8 wk. Birds in the different treatment groups all showed good performance. At d 0 and 56, Se and glutathione peroxidase (GP x) were analyzed ...
The combination of attenuated Newcastle disease (ND) vaccine with rHVT-ND vaccine at 1 day old is more protective against ND virus challenge than when combined with inactivated ND vaccine.
would induce a long-lasting immunity, with no need for a booster vaccination at a later age. In this context, the duration of immunity delivered by a vaccination programme including a recombinant ...
Experimental Schmallenberg virus infection of pigs.
spleen) were sampled. No clinical impact was observed and all collected samples tested negative for SBV in rRT- PCR. Despite the absence of viremia and virus transmission, low and short lasting amounts of ...
Infectious Bursal Disease: a complex host-pathogen interaction.
virus, IBDV has a high mutation rate and may thus give rise to viruses with a modified antigenicity or increased virulence, as emphasized during the last decades. The molecular basis of pathogenicity and ...
Setting up a SPF chicken model for the pathotyping of West Nile virus (WNV) strains.
higher and longer-lasting viremias than older chickens. In all experimental groups, the detection window for viral RNA in feathers lasted up to 14 dpi. Altogether, the data presented in this study show ...
Effects of lung exposure to carbon nanotubes on female fertility and pregnancy. A study in mice.
long lasting pathological changes in dam lung and liver. Theoretically, lung inflammation due to particle exposure could interfere with female reproductive parameters. Whether the observed lag in ...
Methodologies for Salmonella enterica subsp. enterica subtyping: gold standards and alternatives.
salmonellosis outbreaks require the use of methods that can fingerprint the causative strains at a taxonomic level far more specific than the one achieved by serotyping. During the last 2 decades, alternative ...
Nucleotide polymorphism-based single-tube test for robust molecular identification of all currently described Brucella species.
methods described during the last 20 years to identify Brucella, multiplexed amplification methods offer the cheapest and simplest technical solution for molecular identification. However, one disadvantage ...
The importance of quality assurance/quality control of diagnostics to increase the confidence in global foot-and-mouth disease control.
Foot-and-Mouth Disease Foot-and-Mouth Disease Virus Global Health International Cooperation Laboratories Quality Control Abstract: The last decade international trade in animals and animal products was liberated ...
Intake of ochratoxin A and deoxynivalenol through beer consumption in Belgium.
could be an important contributor to OTA exposure in Belgium, even though a declining trend seems to be apparent during the last year of monitoring. Therefore, efforts should be devoted to maintain the ...
