Evaluation of the kinetics of anti-NP and anti-HA antibody after infection of Pekin ducks with low pathogenic avian influenza virus
replacing the haemagglutination inhibition (HI) test as pre-screening tools. Few comparative studies have been conducted to test sera from domestic ducks for diagnostic purposes. Therefore, we evaluated the ...
A Refined Guinea Pig Model of Foot-and-Mouth Disease Virus Infection for Assessing the Efficacy of Antiviral Compounds.
Pyrazines RNA, Viral Vaccination Viral Vaccines Abstract: An antiviral containment strategy for foot-and-mouth disease (FMD) outbreaks could support or replace current contingency plans in case of an outbreak ...
First isolation, identification, phenotypic and genotypic characterization of Brucella abortus biovar 3 from dairy cattle in Tanzania.
although they seem to be related to genotypes found in Europe, Turkey and China but not related to B. abortus biovar 3 reference strain or genotypes from Kenya. Importantly, replacement heifers are commonly ...
Veal Calves Produce Less Antibodies against C. Perfringens Alpha Toxin Compared to Beef Calves.
perfringolysin. The control group only received milk replacer, whereas in the test group solid feed was provided. Maternal antibodies for alpha toxin were present in 45% of the veal calves and 66% of the beef ...
Detection and Isolation of Swine Influenza A Virus in Spiked Oral Fluid and Samples from Individually Housed, Experimentally Infected Pigs: Potential Role of Porcine Oral Fluid in Active Influenza A Virus Surveillance in Swine.
has the potential to replace nasal swabs for molecular diagnostic purposes. The difficulty to isolate swIAV from oral fluid could pose a drawback for its use in active surveillance programs. Health ...
Method for fluorescent marker swapping and its application in Steinernema nematode colonization studies.
Green Fluorescent Proteins Luminescent Proteins Microscopy, Confocal Rhabditida symbiosis Xenorhabdus Yersinia pseudotuberculosis Abstract: An allelic exchange vector was constructed to replace gfp by ...
Detection of total and PRRSV-specific antibodies in oral fluids collected with different rope types from PRRSV-vaccinated and experimentally infected pigs.
syndrome virus Saliva specimen handling Swine Viral Vaccines Abstract: BACKGROUND: Oral fluid collected by means of ropes has the potential to replace serum for monitoring and surveillance of important swine ...
Characteristics of serology-based vaccine potency models for foot-and-mouth disease virus.
of animals each year. Despite considerable efforts during the past decades, a challenge-free alternative vaccine potency test to replace the European protective dose 50% test (PD (50)) has not been ...
Classical swine fever virus detection: results of a real-time reverse transcription polymerase chain reaction ring trial conducted in the framework of the European network of excellence for epizootic disease diagnosis and control.
or suboptimal sensitivity with only a single CSFV genotype. Follow-up actions involved either improvement of suboptimal assays or replacement of specific laboratory assays with the FLI protocol, with ...
Diagnostic performance and application of two commercial cell viability assays in foot-and-mouth disease research.
quantitative spectrometric reading to replace the time-consuming and subjective microscopic (MIC) evaluation of the FMD virus-induced cytopathic effect (CPE). Therefore, the diagnostic performance of two ...
