Following genetic immunization of laying ducks with a plasmid expressing Helicobacter pylori UreB (large subunit of urease), IgY against UreB were obtained from egg yolks. These polyclonal and monospecific IgY antibodies are of higher-titer and specifically recognize recombinant H. pylori urease purified from Escherichia coli. To our knowledge this is the first report describing generation of I...
BACKGROUND Leishmania transmission occurs in the presence of insect saliva. Immunity to Phlebotomus papatasi or Lutzomyia longipalpis saliva or salivary components confers protection against an infection by Leishmania in the presence of the homologous saliva. However, immunization with Lutzomyia intermedia saliva did not protect mice against Leishmania braziliensis plus Lu. intermedia saliva. I...
T-cell responses to viruses are still poorly investigated in lower vertebrates. In rainbow trout, a specific clonal expansion of T cells in response to infection with viral haemorrhagic septicaemia virus (VHSV) was recently identified. Expanded T-cell clones expressed a unique 8 aa Vbeta4-Jbeta1 junction (SSGDSYSE) in different individuals, reminiscent of a typical public response. To get furth...
The covalent binding of [3H]aflatoxin B1 (AF) to liver DNA was determined, 6 h after oral administration to male rabbits. A Covalent Binding Index, CBI (mumol AF/mol DNA-P)/(mmol AF/kg b.w.) = 8,500 was found. Pretreatment of rabbits with AF coupled to bovine serum albumin in Freund's adjuvant led to the production of AF-directed antibodies. Administration of [3H]AF to such immunized rabbits re...
