Attempt with oral immunobiotherapy (broncho-vaxom) and immunochemotherapy (broncho-vaxom + neomycin) for the elimination of bacteria in symptom-free "other Salmonella" carriers.

Forty-five symptomless "other Salmonella" carriers were treated; stool became negative for Salmonella in 22 of the 25 patients treated with Broncho-Vaxom (88%) and in 16 of the 20 patients treated with Broncho-Vaxom + Neomycin (80%) (who had discharged Salmonella for not longer than one month previously). This result is very favourable when compared to data of references of thoroughly controlled patients according to which 69% was the highest rate of bacterial negativity obtained in the treated patients who discharged "other Salmonellas" for not longer than 1 month. The stool of all 10 patients admitted as symptomless carriers of "other Salmonellas" became negative for bacteria in response to the mentioned therapy (in 6 cases of Group I, and 4 cases of Group II). Treatment was unsuccessful primarily in chronic alcohol addicts and toxicosis cases (13%). The unresponsiveness of the two patients suffering from cholelithiasis and excreting also "other Salmonella" with the bile deserves attention. In such cases the positivity of the bile for Salmonella was a reason for exclusion from the study. Further studies (completed with immunological data) are required to assess the value of Broncho-Vaxom immunobiotherapy, and Broncho-Vaxom + Neomycin immunotherapy.
