A Role for B Cells to Transmit Hepatitis C Virus Infection.
with and infect immune cells and may thereby evade host immune surveillance and elimination. To evaluate whether B cells play a role in HCV transmission, we assessed the ability of B cells and sera from ...
Circulation of pertussis and poor protection against diphtheria among middle-aged adults in 18 European countries.
IgG- DTP specific antibodies. The proportion of sera with pertussis toxin antibody levels ≥100 IU /mL, indicative of recent exposure to pertussis was comparable for 13/18 countries, ranging between ...
Evaluating SARS-CoV-2 spike and nucleocapsid proteins as targets for antibody detection in severe and mild COVID-19 cases using a Luminex bead-based assay.
and IgA antibodies in a panel of sera that includes recent (up to six weeks after symptom onset, severe n = 44; and mild cases n = 52) and old infections (five months after symptom onset, mild n = 104), ...
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), ...

Keywords: duck immune response HI test notifiable avian influenza NP ELISA Pekin duck serological diagnosis Abstract: Serological monitoring is a feature of surveillance programmes for the detection of the ...
A Belgian Serosurveillance/Seroprevalence Study of Diphtheria, Tetanus and Pertussis Using a Luminex xMAP Technology-Based Pentaplex
16.3 (11.7-22.7) IU /mL for FHA and 15.4 (10.1-23.6) IU /mL for Prn. Antibody concentrations were below the protective level of 0.1 IU /mL in 26.4% of the sera for DT and in 8.6% of the sera for TT. ...
Serodiagnosis of whooping cough in Belgium: results of the National Reference Centre for Bordetella pertussis anno 2013.
early diagnosis of the disease and PCR analysis on nasopharyngeal swabs is the method of choice during the first 2 weeks and always for young children <1 year old. For sera collected during the first ...

in Belgium concerned samples collected during 1993-1994. In the context of the Eupert-Labnet WP6 seroprevalence study (comparing sera from 16 European member states), 1500 anonymized leftover ...
Use of Strep-tag II for rapid detection and purification of Mycobacterium tuberculosis recombinant antigens secreted by Streptomyces lividans
of serum from tuberculosis patients versus healthy persons by ELISA showed that both S. lividans-derived antigens were recognized by sera of individuals infected with M. tuberculosis, indicating that ...
High heterogeneity in methods used for the laboratory confirmation of pertussis diagnosis among European countries, 2010: integration of epidemiological and laboratory surveillance must include standardisation of methodologies and quality assurance....
laboratories used purified PT as coating antigen and 10 included World Health Organization (WHO) or Food and Drug Administration (FDA) reference sera in their tests. This present survey shows that methods used ...
