which contained viruses from Greece isolated between 1986 and 1997 and from Belgium in 1991 and the other which contained viruses from Italy (1986-1996), Cyprus (1994-1995), France (1995) and ...
Use of a monoclonal antibody against an Escherichia coli O26 surface protein for detection of enteropathogenic and enterohemorrhagic strains46
21 kDa for an O26 strain containing the intimin gene (eae) and verocytotoxin (VT), but not with an O26 eae- and VT-negative strain, or O157 eae- and VT-positive strains. The MA b was used in a sandwich ...

Characterisation of chicken monocytes, macrophages and interdigitating cells by the monoclonal antibody KUL01.
spleen and gut macrophages contained non-specific esterase and acid phosphatase activities characteristic for antigen-processing. Further, it was demonstrated that KUL01-reactive peripheral blood monocytes ...
Neomycin: microbiological assay or liquid chromatography?36676
a microbiological assay was performed on three neomycin samples containing respectively, 0.12, 2.1 and 11% (m/m) of neomycin C, as well on a pure neomycin C sample. The potency was determined according to the ...
Differentiation of the seven serotypes of foot-and-mouth disease virus by reverse transcriptase polymerase chain reaction.
PCR to detect FMDV regardless of the serotype. Positive cDNA was assayed in two multi-primer PCR mixes containing type-specific primers capable of distinguishing between the seven serotypes. The ...
