Haemophilus influenzae biogroup aegyptius

Biogroup: aegyptius

Haemophilus influenzae biogroup aegyptius (Hae) was discovered independently by Koch and Weeks in the 1880s. It is a causative agent of conjunctivitis. In and around the São Paulo State of Brazil during the mid 1980s to early 1990s a highly virulent clonal group of Hae was found to be responsible for Brazilian purpuric fever (BPF), an acute septacaemic fulminant illness of children.
