The bactericidal activity of serum is an important primary host defence against gram-negative bacteria. Little is known regarding such antibodies that are specific to outer membrane (OM) antigens as pili and lipooligosaccharides (LOS) in the bactericidal killing of Haemophilus ducreyi. Presence of serum antibodies with specificity to a 430 kDa protein (polymer of the 24 kDa protein, named fine-tangled pili) and LOS in serum from chancroid patients and healthy individuals were investigated by… CONTINUE READING
