Improved Metrological Traceability of Particle Size Values Measured with Line-Start Incremental Centrifugal Liquid Sedimentation.

the uncertainty of the measurement results and to compare them with results obtained by others. We present the results of a collaborative study that aimed at demonstrating the traceability of particle ...

Selection and transfer of an IncI1-tet(A) plasmid of Escherichia coli in an ex vivo model of the porcine caecum at doxycycline concentrations caused by crosscontaminated feed.

RESULTS: A DOX-resistant, tet(A)-carrying, porcine commensal E. coli strain (EC 682) was cultivated for 6 days in the porcine caecum model under different conditions (0, 1 and 4 mg l(-1) DOX). EC 682, other ...

Laboratory validation of two real-time RT-PCR methods with 5'-tailed primers for an enhanced detection of foot-and-mouth disease virus.

Keywords: 5' Untranslated Regions Animals DNA Primers Foot-and-Mouth Disease Foot-and-Mouth Disease Virus Reproducibility of Results Reverse Transcriptase Polymerase Chain Reaction RNA, Viral Sensitivity ...

Evaluation of 16 commercial antibody ELISAs for the detection of bovine viral diarrhea virus-specific antibodies in serum and milk using well-characterized sample panels.

s (min. 94%, max. 100%). Both DS e and AS e were lower when testing milk samples compared to serum samples. These results confirm that serologic monitoring of BVDV-free herds should be performed using serum ...

Specific antibody-mediated immunity in the reproductive tract of laying chickens immunized against Newcastle disease with conventional attenuated and inactivated vaccines.

points and oviduct segments, all samples were positive for commercial ND- ELISA and in-house ELISA-IgG. However, six of these ELISA-IgG positive samples yielded negative results when submitted to the HI ...

Impact of Acanthamoeba Cysts on Stress Resistance of Salmonella enterica Serovar Typhimurium, Yersinia enterocolitica 4/O:3, Listeria monocytogenes 1/2a, and Escherichia coli O:26.

monocytogenes (99%) after sodium hypochlorite treatment compared with that of nonprimed bacteria. IMPORTANCE The results from this study demonstrated that both viable and nonviable amoebal cysts can protect ...

Imported human brucellosis in Belgium: Bio and molecular typing of bacterial isolates, 1996-2015.

Belgium, were analyzed by both classical biotyping and MLVA, and the genetic patterns compared to those of human strains isolated worldwide. RESULTS: Classical biotyping revealed that isolates were mainly ...

Exploring the Diversity of Field Strains of Brucella abortus Biovar 3 Isolated in West Africa.

a systematic review were compared using a clustering analysis and the Hunter-Gaston diversity index (HGDI). Thus, the analysis of the 42 MLVA genotyping results found in the literature on West Africa [i.e., from ...
