Risk to human health related to the presence of perfluorooctane sulfonic acid and perfluorooctanoic acid in food
increase in serum total cholesterol in adults, and the decrease in antibody response at vaccination in children were identified as the critical effects. For PFOA, the increase in serum total cholesterol was ...
Sera from different age cohorts in Belgium show limited cross-neutralisation between the mumps vaccine and outbreak strains
if a difference in seroneutralising capacity against the vaccine and wild type viruses exists and if waning immunity could be detected. METHODS: In this study, 570 serum samples (age group 2-3y (N=96), ...
Seroprevalence of border disease virus and other pestiviruses in sheep in Algeria and associated risk factors.
6 and 24 months of age (n = 576) and from lambs younger than 6 months (n = 113). All samples were tested by RT- PCR as well as by Ag- ELISA, to detect Persistently Infected (PI) animals. Serum samples ...
Very Long Persistence of Botulinum Toxin B in a Patient’s Serum
method. Botulinum toxin was still detected in the serum up to 29 days after food consumption while it was not detected anymore in the faeces. Conclusion: The described case highlights i) prolonged presence ...
Evaluation of mycobacteria-specific gamma interferon and antibody responses before and after a single intradermal skin test in cattle naturally exposed to M. avium subsp. paratuberculosis and experimentally infected with M. bovis.
infected with a Belgian field strain of M. bovis. Heparinized blood, serum and fecal samples were collected at regular time intervals for mycobacteria-specific IFN-γ release assays, antibody analysis and for ...
Susceptibility of Pigs to Zoonotic Hepatitis E Virus Genotype 3 Isolated from a Wild Boar.
in serum, bile, liver, spleen, duodenum, jejunum, colon, lung, gastro-hepatic lymph nodes and faeces in all infected piglets. After oral inoculation, HEV RNA was detected in serum, bile, liver, ...
Virulence and immunogenicity of genetically defined human and porcine isolates of M. avium subsp. hominissuis in an experimental mouse infection
lungs, spleen and liver and mycobacteria specific spleen cell IFN-γ, IL-10 and IL-17 production as well as serum antibody responses were analyzed. Isolates varied in virulence, with human and porcine ...
Pertussis diagnosis in Belgium: results of the National Reference Centre for Bordetella anno 2015.
Young adult Abstract: In 2015, the Belgian National Reference Centre for Bordetella analyzed 4110 respiratory samples by qPCR and 4877 serum samples by serology. Whereas about 50% of respiratory samples ...
Evaluation of 16 commercial antibody ELISAs for the detection of bovine viral diarrhea virus-specific antibodies in serum and milk using well-characterized sample panels.
p.1040638717724839 (2017) Abstract: We performed a thorough fit-for-purpose evaluation of commercial ELISA s for the detection of bovine viral diarrhea virus (BVDV)-specific antibodies in serum and in milk by testing ...
Genetically stable infectious Schmallenberg virus persists in foetal envelopes of pregnant ewes.
persisting until the moment of birth in the foetal envelopes of ewes infected with SBV-infectious serum at day 45 (⅕ positive) and 60 (4/6 positive) of gestation. This persistence of at least 100 days is a new ...
