Vaccines, Synthetic Viral Fusion Proteins Viral Vaccines Abstract: The recurrent outbreaks of fatal Newcastle disease (ND) in commercial poultry flocks throughout the world indicate that routine vaccinations ...
Distinction between persistent and transient infection in a bovine viral diarrhoea (BVD) control programme: appropriate interpretation of real-time RT-PCR and antigen-ELISA test results.
individual samples from the same herd were pooled (maximum of 30 individual samples per pool) and screened for the presence of Bovine Viral Diarrhoea Virus (BVDV)-specific RNA using a commercial real-time RT- ...
Calibration of Ph. Eur. BRP batch 4 for oral poliomyelitis vaccine (OPV)
the collaborative study to calibrate the candidate BRP (cBRP), a commercial trivalent OPV containing live attenuated poliovirus types 1, 2 and 3 (Sabin strain), against the WHO 2nd International ...
Selenium content of Belgian cultivated soils and its uptake by field crops and vegetables.
Belgium. All samples were collected on commercial production fields, omitting private gardens. All crops were analyzed for their selenium (Se) concentration. The soils represent different soil types ...
Serological evidence of Ostertagia ostertagi infection in dairy cows does not impact the efficacy of rabies vaccination during the housing period33969
investigated in a commercial dairy herd of 46 cows. During the stabling period, all animals received a single intramuscular administration with a commercial inactivated rabies vaccine (Rabisin(R), Merial). The ...
Validation of a new ELISA method for in vitro potency testing of hepatitis A vaccines
hepatitis A virus antigen content in hepatitis A vaccines(HAV) marketed in Europe. This became necessary due to issues with the method used previously, requiring the use of commercial test kits. The selected ...
Effect of a DIVA vaccine with and without in-feed use of coated calcium-butyrate on transmission of Salmonella Typhimurium in pigs.
control group (P < 0.01). Seroconversion was detected in none of the vaccinated animals before challenge, when using a commercial lipopolysaccharide (LPS) ELISA targeting only Salmonella O-antigens, ...
SYBR®Green qPCR Salmonella detection system allowing discrimination at the genus, species and subspecies levels.
assays. Each detection level displayed a selectivity of 100 %. This combinatory SYBR ®Green qPCR system was also compared with three commercially available Salmonella qPCR detection kits. This comparison ...
PFAS determination in fish by UPLC-MS/MS
numerous industrial and commercial applications. Due to the large human exposure, the European Union encourages member states to develop methods for the monitoring of PFAS in food (2010/161/ EU). A method ...
Using conventional HIV tests on oral fluid36499
fluid specimens. Different choices/algorithms adapted for the purpose of testing can be proposed. In conclusion, it can be said that the commercial ELISA s with adapted protocol and cut-off values are ...
