Putative roles of the CNF2 and CDTIII toxins in experimental infections with necrotoxigenic Escherichia coli type 2 (NTEC2) strains in calves.
colostrum-restricted calves were orally inoculated with an Escherichia coli strain, identified originally as non-pathogenic, and into which the plasmid pVir was conjugally transferred. This resulted in diarrhea, ...
Salmonella on pig carcasses: positive pigs and cross contamination in the slaughterhouse36717
carriage is high, but it is obvious that slaughterhouse hygiene is a determinative factor for managing carcass contamination Service: Foodborne pathogens Pathogènes alimentaires Voedselpathogenen Manuscript ...
Molecular characterisation of three avian paramyxovirus type 1 isolated from pigeons in France.
isolate was found to be very closely related to non-pathogenic vaccine strains of aPMV-1, even for its F protein cleavage site motif. Strains 99299 and 99106, typical pigeon paramyxovirus type 1 (pPMV-1) ...

Evolution of pigeon Newcastle disease virus strains.
the F2 / F1 cleavage site of all isolates was typical for pathogenic paramyxovirus 1 viruses. Amino acids at the F2 / F1 cleavage site changed from (112) GRQKRF (117) to (112) RRQKRF (117), (112) RRKKRF ...
