Inner core lipopolysaccharide (LPS) has been shown to be conserved in the majority of veterinary strains from the species Mannheimia haemolytica, Actinobacillus pleuropneumoniae and Pasteurella multocida and as such is being considered as a possible vaccine antigen. The proof-in-principle that a LPS-based antigen could be considered as a vaccine candidate(More)
We investigated the conservation and antibody accessibility of inner core epitopes of Moraxella catarrhalis lipopolysaccharide (LPS) in order to assess their potential as vaccine candidates. Two LPS mutants, a single mutant designated lgt2 and a double mutant termed lgt2/lgt4, elaborating truncated inner core structures were generated in order to preclude(More)
We investigated the immune responses of rabbits that were immunised with lipopolysaccharide (LPS)-based glycoconjugates by measuring the reactivity of the derived sera to a panel of selected wild-type and mutant strains of Neisseria meningitidis. In all cases, high titers of antibodies capable of recognising LPS elaborating the identical structure as(More)
The C chemokine lymphotactin has been characterized as a T cell chemoattractant both in vitro and in vivo. To determine whether lymphotactin expression within tumors could influence tumor growth, we transfected an expression vector for lymphotactin into SP2/0 myeloma cells and tested their ability to form tumors in BALB/c and nude mice. Transfection did not(More)
The C chemokine lymphotactin (Lptn) has been reported to act specifically on CD4(+) and CD8(+) T lymphocytes and natural killer (NK) cells, but not monocytes. However, the chemotactic effect of Lptn on other types of hematopoietic cells has not been well studied. In this study we investigated (i) the chemotactic influences of Lptn on T and B lymphocytes,(More)
A lipoteichoic acid has recently been shown to be conserved in the majority of strains from Clostridium difficile and as such is being considered as a possible vaccine antigen. In this study we examine the candidacy of the conserved lipoteichoic acid by demonstrating that it is possible to elicit antibodies against C. difficile strains following(More)
In previous studies protective antibodies that could facilitate bactericidal killing of Neisseria meningitidis (Nm) serogroup B strains were derived from immunisation with glycoconjugates prepared from O-deacylated lipopolysaccharide (LPS-OH) via direct reductive amination between the reducing end of the oligosaccharide molecule, created by treatment with(More)
In this study we have prepared glycoconjugates with core oligosaccharides (OS) from the lipopolysaccharide (LPS) of Neisseria meningitidis, thus avoiding the neo-epitopes of the deacylated lipid A region of the derived LPS molecule identified in our previous studies. A comprehensive investigation was performed with glycoconjugates prepared from the most(More)
