Use of a serological approach for prediction of Salmonella status in an integrated pig production system31
Technique Test Time Factors Type Universities university use variables veterinary Veterinary Medicine work Abstract: Relevance of a Salmonella serological detection technique was studied from complete results ...
A multiplex PCR to identify porcine mycoplasmas present in broth cultures.
clinical samples using the same media. We have developed a multiplex PCR as a helpful tool for rapid differentiation of these three species in the course of isolation. Based on the 16S ribosomal DNA ...
Permeability of 13 different gloves to 13 cytotoxic agents under controlled dynamic conditions.
using the middle finger of each glove. Linearity, reproducibility, and sensitivity were evaluated for each drug tested. Assays were run using liquid chromatographic tandem mass spectrometry (LC / MS / MS) ...
Ochratoxin A and citrinin loads in stored wheat grains: impact of grain dust and possible prediction using ergosterol measurement.
describes the results obtained using a lab model developed in order to assess the impact of grain dust incorporation for its direct contribution as a contaminant but also as an inoculum in stored wheat. ...
Optimisation of a liquid chromatography-tandem mass spectrometric method for the determination of acrylamide in foods
chromatography coupled to tandem mass spectrometry analysis on a µBondapak C18 column using d3-acrylamide as internal standard. For identification, relative retention time and two diagnostic ions were monitored. ...
Estimation of seroprevalence of encephalomyocarditis in Dutch sow herds using the virus neutralization test.
EMCV antibodies using the virus neutralization test (VN test). The apparent prevalence of EMCV antibodies was 9.3% in the total sow population, and the apparent herd prevalence was 58.8%. An exact ...
Development of a fast analytical method for the determination of sudan dyes in chili- and curry-containing foodstuffs by high-performance liquid chromatography-photodiode array detection
a photodiode array detector. The chromatographic separation is carried out on a reverse phase C18 column with an isocratic mode using a mixture of acetonitrile and water. An “in-house” validation was achieved in ...
Clinical utility of HPV-DNA detection: triage of minor cervical lesions, follow-up of women treated for high-grade CIN: an update of pooled evidence.
with ASCUS or LSIL. We also performed meta-analyses to examine the best predictor of recurrence of CIN after treatment for CIN2 or CIN3. RESULTS: We found that HPV testing using the Hybrid Capture II ...
Quality assurance/quality control of foot and mouth disease solid phase competition enzyme-linked immunosorbent assay--Part I. Quality assurance: development of secondary and working standards.
to grow, further standardisation and harmonisation of antibody detection assays for infectious diseases are needed, especially regarding the development and use of reference materials. For OIE ...
Quality assurance/quality control of foot and mouth disease solid phase competition enzyme-linked immunosorbent assay--Part II. Quality control: comparison of two charting methods to monitor assay performance.
diagnostic assays are subject to random variation resulting in shifts in the mean test values. Continuous monitoring of assays using control charts will alert the interpreter of changes in performance. For ...
