[A trial with attenuated live Salmonella typhimurium vaccine for protection against an experimental Salmonella infection in pigeons].

A live, attenuated Salmonella typhimurium vaccine, available on the market, was administered to six pigeons. The strain of vaccine could not be identified in the droppings of pigeons up to ten days after administration. The pigeons as well as controls were experimentally infected with a Salmonella typhimurium var. copenhagen pigeon strain four weeks after vaccination. Differences in excretion of the var. copenhagen strain and in the appearance of diarrhoea and polyuria between the vaccinated and non-vaccinated pigeons were not detected.
