[Treatment of chronic diarrhea in dogs and cats under field conditions using oral E. coli vaccines].

An autogenous oral E. coli vaccine was tested for efficacy in the treatment of chronic diarrhoea in dogs (n = 82) and cats (n = 50) under field conditions. The data were collected through evaluation of questionnaires completed and returned by veterinarians. After oral application of the E. coli vaccine the symptoms of diarrhoea were stopped in 71% of the treated animals within two to five days. In further 15% of the cases the enteric symptoms continued but were not so severe as in the beginning of the treatment. There was no therapeutic success with the oral E. coli vaccine in further 14% of the animals in cause of food allergy, ascariasis, volvulus or pancreatic insufficiency.
