[The effect of Opisthorchis invasion on the clinical course and outcome of abdominal typhoid. Indicators of non-specific resistance and phagocytosis in patients with abdominal typhoid combined with chronic opisthorchiasis].

A number of non-specific resistance indices (complement, properdin, lysozyme, bactericidal activity of blood serum, phagocytosis indices) in Opisthorchis-invaded abdominal typhoid patients as well as in acute and chronic carriers of Salmonella typhi was inferior to those of uninvaded patients (with the exception of bactericidal index). Complete recovery from opisthorchiasis stimulated the cessation of S. typhi elimination and increase in the level of some non-specific resistance factors.
