Prior infection with an H1N1 swine influenza virus partially protects pigs against a low pathogenic H5N1 avian influenza virus.

infection induced high levels of H5N1 cross-reactive NI antibodies. Cross-reactive CMI was demonstrated by measurements of lymphoproliferation and IFN-gamma secretion after in vitro restimulation of ...

Prevalence of enterotoxigenic Escherichia coli virulence genes from scouring piglets in Zimbabwe.

F1-like fimbriae, or lacked fimbriae. The data constitute an important framework for implementation of prevention measures, such as using relevant fimbriae-based vaccines against ETEC induced diarrhea or ...

Validation of two real-time RT-PCR methods for foot-and-mouth disease diagnosis: RNA-extraction, matrix effect, uncertainty of measurement and precision.

determine analytical and diagnostic sensitivity and specificity, a thorough validation in terms of establishing optimal RNA-extraction conditions, matrix effect, uncertainty of measurement and precision is ...

Trace elements in home-produced eggs in Belgium: levels and spatiotemporal distribution.

mercury corresponded well with values measured in other countries, while copper and zinc concentrations were within the same order of magnitude as in other countries. Average lead concentrations were high ...

Transfer of soil contaminants to home-produced eggs and preventive measures to reduce contamination.

produced eggs. It was the aim of this study to identify the major source of two environmental pollutants in home-produced eggs, i.e. dioxins and lead, to formulate preventive measures to reduce the ...

Humoral, cell-mediated and mucosal immunity induced by oculo-nasal vaccination of one-day-old SPF and conventional layer chicks with two different live Newcastle disease vaccines.

similar humoral immune-response was measured in blood and tears but a differential profile of cell-mediated immunity was observed according to the vaccine strain. The lung-associated humoral immunity was ...

Diversity and habitat specificity of free-living protozoa in commercial poultry houses.

Housing, Animal Nucleic Acid Denaturation Poultry Abstract: Despite stringent biosecurity measures, infections by bacterial food pathogens such as Campylobacter are a recurrent problem in industrial poultry ...

Electron tomography of negatively stained complex viruses: application in their diagnosis.

allows visualizing and measuring artifacts typical for negative staining. This approach allows sharp visualisation of structures in a subnanometer-thick plane, avoiding blurring due to superposition which ...

Technical note: Flow cytometric identification of bovine milk neutrophils and simultaneous quantification of their viability.

iodide was used to determine milk PMNL viability. Thirty milk samples were run in parallel to assess the repeatability of the immunoassay and 6 repeated measurements per sample were performed to assess the ...

Possible routes of introduction of bluetongue virus serotype 8 into the epicentre of the 2006 epidemic in north-western Europe.

or independently of the import of animals, plants or other ‘materials’, and the effectiveness of measures to reduce such a possibility, merit further study. Health Topics:  Animal health Category:  A1 ...
