Enterotoxigenic coagulase positive Staphylococcus in milk and milk products, lben and jben, in northern Morocco.
determine the prevalence of enterotoxin genes (sea-seo) in Coagulase Positive Staphylococcus (CPS) isolated from unpasteurized milk and milk products. These results were compared with the results obtained by ...
Association between habitat and prevalence of hantavirus infections in bank voles (Myodes glareolus) and wood mice (Apodemus sylvaticus).
Rodent Diseases Abstract: In order to determine the habitat preferred by Myodes (before Clethrionomys) glareolus and the corresponding Puumala hantavirus seroprevalence in those habitats, we captured ...
Optimization and validation of a liquid chromatography tandem mass spectrometry (LC/MSn) method for analysis of corticosteroids in bovine liver: evaluation of Keyhole Limpet beta-glucuronidase/sulfatase enzyme extract.
Mass Spectrometry VALIDATION Abstract: A liquid chromatography tandem mass spectrometry (LC / MS (n)) method for the determination of 12 corticosteroids in bovine liver has been optimized and validated ...
Accumulation of trace elements in cattle from rural and industrial areas in Belgium.
element concentrations were determined in meat, kidney and liver tissue of cattle, which had resided more than 18 months in areas historically contaminated by emissions from the non-ferrous metal industry ...
Technical note: Flow cytometric identification of bovine milk neutrophils and simultaneous quantification of their viability.
iodide was used to determine milk PMNL viability. Thirty milk samples were run in parallel to assess the repeatability of the immunoassay and 6 repeated measurements per sample were performed to assess the ...
Some guidelines for determining foot-and-mouth disease vaccine strain matching by serology.
of foot-and-mouth disease (FMD) virus can be assessed in vivo or by serological r-value determination. Sera from animals involved in vaccine potency and cross-protection trials performed using the ...
Determination of bixin and norbixin in meat using liquid chromatography and photodiode array detection
The possibilities of ion trap mass spectrometry (MS) were also assessed. Method performance characteristics, according to Commission Decision 2002/657/ EC, were determined, with recoveries between 99 ...
Quantification of Campylobacter spp. in chicken carcass rinse by real-time PCR36795
sensitivity and the detection limit of the method was 3.3 log CFU per carcass. The statistical correlation between the bacteriological enumeration and the real-time quantitative (Q)- PCR determined using ...
Establishment of Replacement Batches for Prekallikrein Activator in Albumin Biological Reference Preparation
method 2.6.15 for the determination of prekallikrein activator content. A central statistical analysis was performed at the EDQM using in-house calculations of prekallikrein activator contents provided by ...
The polymeric stability of the Escherichia coli F4 (K88) fimbriae enhances its mucosal immunogenicity following oral immunization.
subunit FaeG that is also the fimbrial adhesin. In the present study, the mutagenesis experiments identified FaeG amino acids 97 (N to K) and 201 (I to V) as determinants for F4 polymeric stability. The ...
