title: [Frequency of serologic conversion of complement fixing antibodies FC by respiratory viruses in cases of acute juvenile respiratory disease].
abstract: The complement fixation test, run on double samples of serum pertaining to 447 children hospitalized between January 1971 and June 1974 at Ospedale Maggiore in Novara, or checked in consulting rooms for acute phlogosis of the respiratory organs, has permitted to detect in 241 children, equal to the 53,9% of the total cases, a significant increase of antibodies for respiratory viruses (Influenza A, B, C, Parainfluenza 1, 2, 3. Respiratory syncytial virus, Adenovirus, Reovirus). Specifically, in the 40,0% of the total cases, the serological conversion was evidenced for one virus only, and in the 13,8% for 2-3 viruses, raising in this last cases, questions concerning the diagnosis at a serological level.
