A comparative genetic study of serologically distinct Haemophilus influenzae type 1 immunoglobulin A1 proteases.

Journal of bacteriology - 1 May 1992

Poulsen K, Reinholdt J, Kilian M

Abstract excerpt

The bacterial immunoglobulin A1 (IgA1) proteases are putative virulence factors secreted by a number of human pathogens capable of penetrating the mucosal barrier. Among Haemophilus influenzae strains, the IgA1 protease is found in several allelic forms with different serological neutralizing properties. A comparison of the primary structures of four serologically distinct H. influenzae IgA1 proteases suggests...
