[Phage typing and biotyping of salmonella typhi-murium (author's transl)].
1998 strains of Salmonella typhi-murium from two different regions of West-Germany were investigated according to their biotype and phagetype. 132 strains were isolated from sewage, 320 strains from animals and the others from human beings. 60 different phagetypes were found. The phagetype 49 occurred most often (11,9% resp. 10,3%). A correlation between biotype and phagetype could not be observed. Nearly every phagetype could be divided into several biotypes. However, only few biotypes prevaled. These comprised the biotypes 1, 10 and 17. The examination of the splitting of trehalose was useful in the biochemical differentiation. Concerning strains of animal origin it was remarkable that most strains from cattle resp. calves belonged to the phagetype 49. Among 145 strains from pigeons 95,9% could be classified as phagetype 2. With exception of 3 strains all the other strains from pigeons did not possess the O-antigen 5. The majority of the strains belonged to the biotype 8. All these strains could not split maltose.
