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

test. Interestingly, NDV-specific IgM and IgA were detected frequently in the infundibulum and magnum as compared to the isthmus and uterus. These results show that the antibody immune response in the ...

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 ...

Genetically stable infectious Schmallenberg virus persists in foetal envelopes of pregnant ewes.

foetal envelopes is genetically stable since only a few mutations compared to the inoculum were found. This supports the hypothesis that persisting virus could start the infection of new hosts. Finally, ...

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 ...

Effect of residual doxycycline concentrations on resistance selection and transfer in porcine commensal escherichia coli.

significantly higher at 1 and 4 mg/L DOX compared to the blank control, but no significant difference between 1 and 4 mg/L was seen. Plasmid transfer frequencies were affected by 1 or 4 mg/L DOX in the medium for ...

Three Different Routes of Inoculation for Experimental Infection with Schmallenberg Virus in Sheep.

showed RNA emia, the viral genome could be detected in spleen and mesenteric lymph nodes. Both the SC and ID routes seem suitable to properly reproduce field conditions, as comparable observations were ...

Evaluation of three competitive ELISAs and a fluorescence polarisation assay for the diagnosis of bovine brucellosis.

available C- ELISA kits (C- ELISA1-3) and FPA for the diagnosis of bovine brucellosis and compare test performance with RBT, CFT, indirect ELISA and FPA. Sera submitted to EU laboratories in 2011 from 5111 ...

Seroprevalence of brucellosis in patients with prolonged fever in Bangladesh.

higher in pyretic patients who had backache compared to those without backache. B. abortus DNA was amplified from all six human sera that tested positive by RBT, STAT, and iELISA. As the agreement between ...
