  Background : An accurate and prompt diagnosis of bacterial arthritis is essential for earlier treatment and a good outcome. Superantigens produced by Staph. Aureus are among the most lethal toxins. The paper objective was Identification of common bacterial antigens and S.aureus superantigens in synovial fluid (SF) of children with negative culture and direct smear for other bacteria except fo...

Helicobacter pylori infections are accompanied with the release of some antigenic material into the stool. Outer membranes proteins (OMP) are among the major antigens of bacteria, which in comparison with other bacterial constituents have less cross-reactivity. In this study, OMP of H. pylori were isolated from 11 clinical isolates and rabbit antiserum against them was used to detect possible a...

Bacterial surface proteins can be good vaccine candidates. In the present study, we used polyclonal antibodies purified with intact Erysipelothrix rhusiopthiae to screen phage-displayed random dodecapeptide and loop-constrained heptapeptide libraries, which led to the identification of mimotopes. Homology search of the mimotope sequences against E. rhusiopthiae-encoded ORF sequences revealed 14...

Water-soluble antigens isolated from acetone-dried, gram-negative bacteria elicited reaginic antibody formation in mice. Antibodies specific for Escherichia coli antigens reacted with antigens isolated from several enterobacterial species tested, but not with antigens isolated from Pseudomonas aeruginosa. Reaginic antibodies induced by antigens isolated from a P. aeruginosa strain reacted with ...
