Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium
about 35% of the samples contained known and/or unknown impurities beyond the Ph. Eur. limits [3]. Concerning the dissolution tests, 47% of samples were not compliant as the amount of drug released is ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
agglomeration state. The measurement of the median value of the minimal external particle diameter distribution was intra-laboratory validated. The validation study included an assessment of the limit of ...
Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
0.25ngg(-1) for all dyes, with a signal-to-noise ratio of at least 10/1. This is at least 5 to 10 times lower than previous published methods. Limits of detection were all <0.1ngg(-1). Precision and trueness ...
Development, validation and evaluation of added diagnostic value of a q(RT)-PCR for the detection of genotype A strains of small ruminant lentiviruses.
circulating in Belgium. The developed q(RT)- PCR targets a region of the gag gene and showed to be highly sensitive and specific with a limit of detection of 6 DNA and 40 RNA copies/reaction respectively. SRLV ...
Effect of saliva stabilisers on detection of porcine reproductive and respiratory syndrome virus in oral fluid by quantitative reverse transcriptase real-time PCR.
presence of PRRSV RNA by qRT- PCR. PRRSV RNA could be detected in oral fluid using all extraction-amplification combinations, but the limit of detection varied amongst different combinations. Storage ...

Influence of isolation methods on the occurrence of plasmid-carrying Yersinia enterocolitica serotype O:3 in slaughter pig tonsils, faeces and carcass surface swabs.
carcass samples were contaminated below the detection limit of enumeration. The relative sensitivity of the methods to recover pathogenic Y. enterocolitica varied among the different matrices. Nevertheless, ...
Development and validation of qualitative SYBR®Green real-time PCR for detection and discrimination of Listeria spp. and Listeria monocytogenes.
of Listeria spp. The selected primers were designed to amplify short fragments (60 to 103 bp) in order to obtain optimal PCR efficiency (between 97 and 107 % efficiency). The limit of detection of the ...
Determination and use of processing factors for pesticide residues after processing of fruit and vegetables: carrot, celery, spinach, melon
thiamethoxam), on the basis of most frequently consumed matrices and of the high frequency of detection for these pesticides. For some combinations pesticide-commodity-processing, significant reductions in residue ...
