[Bread beetle (Stegobium paniceum L.) as Salmonella vector in fodder and fodder mixture (author's transl)]

In 1965 Salmonella eimsbuettel was isolated from two samples of fodder mixture for poultry and one sample of fodder mixture for pigs. In these samples of fodder mixtures there were also numerous specimen of bread beetles (Stegobium paniceum L.). The bread beetles remained in these fodder mixtures during more than 9 years (till June 1974), and by them S. eimsbuettel was proved in one sample of fodder mixture for chickens as well. From the other sample of fodder mixture for chickens Salmonella was isolated during 6 years and from the sample of fodder mixture for pigs S. eimsbuettel was isolated during seven and half years. In 1969 into 12 sterile samples of fodder 5-10 adult bread beetles were inserted. These bread beetles had been taken from fodder mixtures contaminated by S. eimsbuettel and bread beetles. The bread beetles multiplied in these fodder mixtures and from a year thereafter the fodders were searched for Salmonella every 6 months. In 4 samples of fodder (out of 12) S. eimsbuettel was proved till June 1974. The same Salmonella was isolated from well-washed and mashed bread beetles. Therefore the bread beetles (Stegobium paniceum L.) should be included into Salmonella vectors.
