A model for the transfer of passive immunity against Newcastle disease and avian influenza in specific pathogen free chickens.
in early life, when the immune system is immature and unable to fight off infection. On the other hand, MDA can also affect the development of the immune system and interfere with vaccination against ...
Infectious Bursal Disease: a complex host-pathogen interaction.
Infectious Bursal Disease Virus (IBDV) targets the chicken’s immune system in a very comprehensive and complex manner by destroying B lymphocytes, attracting T cells and activating macrophages. As an RNA ...
Evaluation of two different swab transport systems in the detection of avian influenza virus excretion from infected Pekin ducks (Anas platyrhynchos).
order. For influenza A virus matrix gene RNA detection, wet oropharyngeal swabs were significantly more sensitive than dry oropharyngeal on days 4-5 after infection. For cloacal samples, dry swabs were ...
Simultaneous detection of bluetongue virus RNA, internal control GAPDH mRNA, and external control synthetic RNA by multiplex real-time PCR.
analytical sensitivity. Due to the incorporation of the internal/external control system, the triplex RT-qPCR allows an even more reliable and rapid diagnosis of bluetongue than the previously described ...
Evaluation of different serologic markers for the early detection of avian influenza infection in chickens.
pathogenicity notifiable avian influenza (LPNAI) as soon as possible. With the emergence of the highly pathogenic H5N1, markers of infection of avian influenza are becoming more and more significant. They are ...
NUSAP method for evaluating the data quality in a quantitative microbial risk assessment model for Salmonella in the pork production chain.
assessment pedigree (NUSAP) system was implemented to evaluate the quality of input parameters in a quantitative microbial risk assessment (QMRA) model for Salmonella spp. in minced pork meat. The input ...
Validation of a real-time PCR assay for the detection of bovine herpesvirus 1 in bovine semen.
specificity, sensitivity and repeatability using spiked semen and semen from naturally infected animals. The real-time PCR was very rapid, highly repeatable and more sensitive (lower detection limits) than ...
Delivery of DNA vaccines by agarose hydrogel implants facilitates genetic immunization in cattle.
Tests Osmotic Pressure Plasmids Sepharose Vaccination Vaccines, DNA Viral Vaccines Abstract: The present study demonstrates the interest of two slow-release systems as vaccination tools in cattle. Two ...
Decision support tools for clinical diagnosis of disease in cows with suspected bovine spongiform encephalopathy.
(2004) Keywords: Animals Cattle Decision Support Systems, Clinical Decision Trees Encephalopathy, Bovine Spongiform Female Time Factors Abstract: Reporting of clinically suspected cattle is currently the ...
Highly sensitive detection of swine vesicular disease virus based on a single tube RT-PCR system and DIG-ELISA detection.
Abstract: A highly sensitive detection of swine vesicular disease virus (SVDV) based on a single tube RT- PCR system and digoxigenin (DIG)- PCR- ELISA detection was developed. Using a one tube RT- PCR system ...
