teaching hospital is reported. Pulsed-field gel electrophoresis was used for strain typing to determine the origin and dissemination of these strains. All 19 strains harboured the blaCTX-M-14, and six ...
Nontuberculous mycobacteria among pulmonary tuberculosis patients: a retrospective Belgian multicenter study.
the frequency and clinical significance of nontuberculous mycobacteria (NTM) grown from respiratory samples during the treatment of tuberculosis (TB). We determined the frequency and clinical ...
Age-Dependent Differences in Pseudorabies Virus Neuropathogenesis and Associated Cytokine Expression.
PRV pathogenesis. Several new findings and potential explanations for the observed age-dependent differences in virulence, however, were determined from the study of viral and cytokine mRNA expression ...
Isolation and characterization of the compounds responsible for the antimutagenic activity of Combretum microphyllum (Combretaceae) leaf extracts
Solvent-solvent fractionation was used to partition the extracts and by using bioassay-guided fractionation, three compounds were isolated. The antimutagenic activity of the three compounds were determined in the ...
The added value of food frequency questionnaire (FFQ) information to estimate the usual food intake based on repeated 24-hour recalls
the usual dietary intake of foods in a population generally ignore the additional information on the never-consumers. The objective of this study is to determine the added value of Food Frequency ...
Proof-of-concept study of a new LC-ESI-MS/MS-based assay to identify Aspergillus spp. in artificially mixed samples using species/genus-specific proteotypic peptides
the pure material. In conclusion, we have developed an innovative LC- ESI- MS / MS assay which has the capacity to determine the composition of mixed samples, and its proof of concept is shown here ...
Replication-Deficient Particles: New Insights into the Next Generation of Bluetongue Virus Vaccines.
storage conditions of vaccines, including additives, temperature, and desiccation, were determined and their protective efficacies in animals confirmed. Furthermore, to test if mixtures of different vaccine ...
Antimicrobial resistance surveillance in Escherichia coli by using normalized resistance interpretation.
Interpretation (NRI) method. METHODS: The susceptibilities of 921 E. coli isolates from clinically healthy pigs at slaughter age was determined for 15 antimicrobials by the Kirby Bauer disk diffusion technique. ...
Neonatal thyroid-stimulating hormone concentration and psychomotor development at preschool age.
weight and/or prematurity were excluded. Psychomotor development was assessed using the Charlop-Atwell scale of motor coordination. The iodine status of children was determined using median urinary iodine ...
