Presença de substâncias fisològicamente ativas em culturas de E. Coli isolados das fezes de pacientes alérgicos pela técnica de Heist-Cohen

Presence of substances with physiological activity in cultures of E. Coli isolated from stools in allergic patients by the Heist-Cohen pathogen selective method

Resumo

Four patients with several allergic symptoms have been studied. Heist-Cohen pathogen selective method was positive in feces of all these patients for E. coli. Other causes that could be responsible for the allergic symptoms were discarded. Samplets after seeding in a medium physiologically inactive have been tested in guinea pig illea following Cohnheim-Magnus technique. It was demonstrated that all samples isolated by the Heist-Cohen technique were physiologically active.(Fig.1). Ten other strains of E. coli taken at random from the collection of I.O.C. and tried according similar technique, brought evidence that only three samples possessed such activity. This confirms the works of KOESSLER-HANKE (1922). In order to obtain a quick relief from allergic symptoms, one of us had employed in some others, identical cases an antibiotic (Teramycin, Chas Pfeizer) before the specific disesitization was done (Figs. 2, 3, 4, 5). Such method were choice since LABORDE, PARROT, and URQUIA (1953) have demonstrated the importance of production of histamine, from components of the bowel's flora in the production of allergic symptoms.

Four patients with several allergic symptoms have been studied. Heist-Cohen pathogen selective method was positive in feces of all these patients for E. coli. Other causes that could be responsible for the allergic symptoms were discarded. Samplets after seeding in a medium physiologically inactive have been tested in guinea pig illea following Cohnheim-Magnus technique. It was demonstrated that all samples isolated by the Heist-Cohen technique were physiologically active.(Fig.1). Ten other strains of E. coli taken at random from the collection of I.O.C. and tried according similar technique, brought evidence that only three samples possessed such activity. This confirms the works of KOESSLER-HANKE (1922). In order to obtain a quick relief from allergic symptoms, one of us had employed in some others, identical cases an antibiotic (Teramycin, Chas Pfeizer) before the specific disesitization was done (Figs. 2, 3, 4, 5). Such method were choice since LABORDE, PARROT, and URQUIA (1953) have demonstrated the importance of production of histamine, from components of the bowel's flora in the production of allergic symptoms.
