[Clinical results of a multicenter study of Haemophilus infection].

2379 cases of infections due to Haemophilus are reported in a one year long French multicenter study. There were 1368 low respiratory and 540 high respiratory infections, 22 epiglottitis, 86 meningitis, and 68 septicemia (bacteremia). Four hundred and one times, we considered that the bacteria was not the cause of the infection. For each type of infection, we studied the distribution according to the age, the sex and the period of the year, the eventual associations and the involved serotypes. The lethality was low (22), mainly due to a particular deficiency. At last, we compared the different methods to obtain the pathologic products from the upper bronchial tract.
