[The humoral immunity indices and complement functional activity in salmonellosis during the dynamics of the disease].

In 65 patients with bacteriologically confirmed gastrointestinal salmonellosis of moderate severity (41 males and 24 females) the disease in an acute phase was characterized by activation of complement system and specific antibody formation, by a growth in the levels of IgA, G and M. In early convalescence IgA and IgM remained high, IgG in females returned to normal, in males was still high. An inverse correlation was found between functional activity of complement components C3, C4 and C5 and levels of IgM, IgG.
