[Characteristics of the immunity in typhoid infection associated with opisthorchiasis].

Typhoid infection developing in persons with opisthorchiasis is characterized by the appearance of pronounced systemic immunity, that ensures a more favorable clinical course of this infection and promotes a decrease in the occurrence of diarrheal phenomena and bacteremia. At the same time, in typhoid patients, simultaneously affected by opisthorchiasis, a more intensive release of the infective agent into the environment is observed. This seemingly demonstrates the presence of disturbances in the local protective mechanisms regulating the process of the release of bacteria on the level of the gastrointestinal tract.
