Carry-over of some Fusarium mycotoxins in tissues and eggs of chickens fed experimentally mycotoxin-contaminated diets
Volume 145 (2020) Keywords: Broiler chickens Carry-over Egg feed Fusariotoxins Laying hens Liver Meat Muscle SKIN Abstract: Fusarium mycotoxins are fungal contaminants found in different crops intended for ...
Specific antibody-mediated immunity in the reproductive tract of laying chickens immunized against Newcastle disease with conventional attenuated and inactivated vaccines.
Abstract: Despite the widespread and successful use of Newcastle disease (ND) vaccines, Newcastle disease virus (NDV) can seriously injure the reproductive tract of egg-laying hens, leading to rapid egg ...
Complete Genome Sequence of a Vaccinal Newcastle Disease Virus Strain Isolated from an Owl (Rhinoptynx clamator).
A Newcastle disease virus (NDV) was isolated in chicken embryonated eggs after detection by real-time reverse transcription- PCR (RRT- PCR) from a captive owl swab. The complete genome sequence of ...
Protection Afforded by a Recombinant Turkey Herpesvirus-H5 Vaccine Against the 2014 European Highly Pathogenic H5N8 Avian Influenza Strain.
evaluated. SPF chickens were vaccinated subcutaneously at 1 day old and challenged oculonasally at 4 wk of age with two viral dosages, 10(5) and 10(6) 50% egg infective doses. Morbidity and mortality were ...
Comparing responses to different selenium sources and dosages in laying hens.
source, Se-enriched yeast (SelPlex 2300), and sodium selenite, an inorganic Se source, against a commercial control diet. The effect of source and the dosage of Se supplementation on Se in eggs and blood ...
Phage and MLVA typing of Salmonella enteritidis isolated from layers and humans in Belgium from 2000-2010, a period in which vaccination of laying hens was introduced.

What's in a strain? Viral metagenomics identifies genetic variation and contaminating circoviruses in laboratory isolates of pigeon paramyxovirus type 1.
occasionally also detected in stocks passaged in embryonated chicken eggs. Phylogenetic analysis of the PiCV consensus genome sequences showed a circulation of PiCV covering the full genetic diversity of known ...
Susceptibility of pigeons to clade 1 and 2.2 high pathogenicity avian influenza H5N1 virus.
four groups of 1-yr-old and 4-wk-old racing pigeons (10 birds in each group) were inoculated oculonasally with 106 50% egg infectious dose (EID50) of A/crested eagle/Belgium/0½004 (clade 1) or ...
Rapid detection of Eurasian and American H7 subtype influenza A viruses using a single TaqManMGB real-time RT-PCR.
embryonated chicken eggs (VI), the PanH7 detected more weakly positive oropharyngeal swabs at the onset of the infection. PanH7 diagnostic sensitivity compared to virus isolation (VI) was 83.3% (compared to ...
