[Iron uptake of Salmonella typhimurium strains from different epidemiological sources].
All Salmonella typhimurium strains tested were able to use iron from transferrin. In buffered nutrient broth -- poor in iron-content -- the strains were tested in 59FeCl3 and 59Fe-transferrin uptake in different growth phases. In the early log phase the strains are able to catch the 59Fe3+ in a very great amount as it is necessary for the growth. The content of 59Fe per cell was in the late log phase reduced until to a value, which seen to be enough for growth. The acquisition of 59Fe-transferrin between the early and late log phase tested by 4 S.typhimurium strains was different.
