Characteristics of the process of transferrin iron utilization by Yersinia pestis at various incubation temperatures

The study has revealed that for the utilization of iron contained in transferrin the direct contact of Y. pestis with this metalloprotein is necessary. At 28 degrees C Y. pestis utilizes iron contained in transferrin. At 37 degrees C Y. pestis absorbs transferrin, but cannot utilize its iron, which is probably linked with disturbances in the system of the transfer of iron from the transferrin receptor complex into the bacterial cell.
