Multicenter survey of routine determinations of resistance of Helicobacter pylori to antimicrobials over the last 20 years (1990 to 2009) in Belgium36563
from 1990 to 2009 and identified risk factors associated with resistance. Gastric biopsy specimens were collected from several digestive disease centers in Brussels, Belgium. We routinely performed ...
International collaborative study on the occurrence of plasmid-mediated quinolone resistance in Salmonella enterica and Escherichia coli isolated from animals, humans, food and the environment in 13 European countries36580
sequence analysis were performed to identify the responsible PMQR genes. RESULTS: Screening of databases of 13 European countries resulted in a selection of 1215 Salmonella and 333 E. coli isolates. PMQR ...
Dietary intake of hexabromocyclododecane diastereoisomers (α-, β-, and γ-HBCD) in the Belgian adult population.
Hydrocarbons, Brominated Male Stereoisomerism Abstract: A study was performed to assess exposure of the Belgian population to HBCD diastereoisomers. Measurements of HBCD were performed by UPLC- MS / MS, on 45 ...
Occurrence and diversity of free-living protozoa on butterhead lettuce.
Identification of FLP was performed by light microscopy and sequencing of denaturing gradient gel electrophoresis (DGGE)-separated 18S rRNA gene fragments. Bodo saltans, Spumella (-like) spp. and Cercozoa were the ...
Risk factors for ceftiofur resistance in Escherichia coli from Belgian broilers.
coli Infections Microbial Sensitivity Tests Risk Factors Surveys and Questionnaires Abstract: A cross-sectional study on 32 different Belgian broiler farms was performed in 2007 and 2008 to identify risk ...
Deoxynivalenol loads in matched pair wheat samples in Belgium: comparison of ELISA VERATOX kit against liquid chromatography.
27, Issue 2, p.105-13 (2011) Abstract: A comparison of matched pairs deoxynivalenol (DON) loads in wheat samples via VERATOX for DON 5/5 performed by two laboratories against two liquid chromatographic ...
Marching cohort of Helicobacter pylori infection over two decades (1988-2007): combined effects of secular trend and population migration34035
prevalence of Helicobacter pylori infection is decreasing in developed countries. In this study we included 22,612 patients in whom a first culture of gastric biopsy (routinely performed in our medical ...
Standardization of hepatitis E virus (HEV) nucleic acid amplification technique-based assays: an initial study to evaluate a panel of HEV strains and investigate laboratory performance34020
PCR performance plasma RANGE Reproducibility of Results result Rna routine Sample Samples SB- IM Score SENSITIVITY Sensitivity and Specificity STANDARD STANDARDIZATION standards strain study Test ...
Llama-derived single domain antibodies to build multivalent, superpotent and broadened neutralizing anti-viral molecules36549
constructs were similar or better than best performing monoclonal antibodies. The cross protection capacity against different viral strains was also improved for all three viruses, both by multivalent (two or ...
Pertussis serodiagnosis in Belgium from 1990 to 2009.
pertussis by culture and PCR is most sensitive when performed on nasopharyngeal specimens collected <2 weeks and <3 weeks, respectively, after the onset of clinical disease. Conversely, serological ...
