GATTI, B.M. et al. Isolation of Haemophilus influenzae serotypes from sterile sites in sick children. Rev. argent. microbiol. [online]. 2004, vol.36, n.1, pp.20-23. ISSN 0325-7541.

Haemophilus influenzae (Hi) is the causative agent of several human diseases such as sepsis, meningitis, celulitis, and osteoarthritis. We investigated the isolation of Hi serotypes from sterile sites in sick children. One hundred and seventy nine strains from 146 patients were studied, period 1996-2002, at the Microbiology Laboratory, Hospital de Niños Superiora Sor María Ludovica, Argentina. The serotype distribution was:1 a, 112 b,1 c,1 d, 4 e, 3 f y 24 no typable. Since the beginning of universal Hi b vaccination in 1998, we have observed the fast decrease of serotype b and a relative increase of other serotypes.

Keywords : Haemophilus influenzae; serotypes; invasive disease.
