The experiment measured lamb responses to supplementation of the pregnant ewe diet with vitamin E above requirement. Crossbred ewes were mated with either Suffolk or Texel rams. Twin-bearing ewes were randomly allocated (approximately 21 months of age at allocation) to one of four treatment groups (20 ewes per group, 10 mated with Suffolk and 10 with Texel rams). Treatments imposed were 50, 100...

In this study, the immunogenicity of three types of antigens (hydatid fluid, protoscolices and whole body of E. granulosus) was investigated in lambs by ELISA. Sixteen 4–6-month-old lambs of mixed sexes were divided into 4 groups of 4 lambs (three immunized and one control group). Twelve lambs as immunized groups received 2 mg of hydatid fluid, protoscolices and whole body of E. granulosus ant...

LamB protein is involved in the transport of maltose across the outer membrane and constitutes the receptor for phage lambda. In this study we characterized six previously described anti-LamB monoclonal antibodies (mAbs). Four of these, the E-mAbs, recognized determinants that were exposed at the cell surface, whereas the other two, the I-mAbs, recognized determinants which were not exposed. Co...

In this study we demonstrate that most members of the family Enterobacteriaceae possess a maltose-inducible outer membrane protein homologous to the LamB protein of Escherichia coli K-12. These proteins react with polyclonal antibodies raised against the LamB protein of E. coli K-12. We compared the antigenic structure of the LamB protein in members of the family Enterobacteriaceae with six mon...

We have studied the immunological relatedness of LamB proteins from a wide range of enterobacterial species, using antibodies directed against denatured Escherichia coli K12 and Klebsiella pneumoniae LamB proteins (LamBE.c. and LamBK.p., respectively), and anti-peptide antibodies directed against 10 distinct loops of LamB from E. coli K12 predicted to protrude either side of the outer membrane....

Two experiments were conducted to examine effects of d-á-tocopherol (vitamin E) on colostrum immunoglobulin G (IgG) titers and preweaning lamb performance. Trial 1 consisted of 86 Suffolk ewes receiving either no vitamin E (control) or 1500 IU vitamin E on d-28 prepartum. From the 86 ewes, a subset of 25 ewes was randomly chosen for an intensive analysis of ewe serum and colostrum IgG and lamb ...

The present study investigated the effect of maternal vitamin E and fatty acid supplementation on lamb antioxidant status. Forty-eight ewes were fed one of four concentrate diets supplemented with a basal (50 mg/kg) or supranutritional (500 mg/kg) level of vitamin E plus a source of either saturated fat (Megalac; Volac Ltd, Royston, Hertfordshire, UK) or long-chain PUFA (fish oil) from 6 weeks ...

The appearance of newly induced LamB protein at the cell surface of Escherichia coli was followed topographically by immuno-electron microscopy. LamB protein was induced in E. coli wild-type or lac-lamB cells for a short period of time (4 to 6 min), such that the overall level of LamB protein in induced cells was at least twofold higher than that in uninduced cells. Antibodies bound to LamB pro...

in this study, the immunogenicity of three types of antigens (hydatid fluid, protoscolices and whole body of e. granulosus) was investigated in lambs by elisa. sixteen 4–6-month-old lambs of mixed sexes were divided into 4 groups of 4 lambs (three immunized and one control group). twelve lambs as immunized groups received 2 mg of hydatid fluid, protoscolices and whole body of e. granulosus ant...
