R factor proteins synthesized in Escherichia coli minicells: membrane-associated R factor proteins.

R factor proteins are synthesized in R factor-containing Escherichia coli minicells. Half of this protein remained associated with the minicell membrane upon lysis of the minicells. Over 90% of the membrane-associated protein was extracted by sodium lauryl sarcosinate, suggesting a location of these proteins in the inner membrane. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of these membrane preparations demonstrated the presence of multiple peptides, including a prominent band with a molecular weight of 28,000 to 30,000. A polypeptide of similar size was seen in membrane preparations from minicells harboring R factors from five different compatibility types. This major R factor membrane peptide was seen with R factors repressed or derepressed for pilus synthesis, with and without antibiotic resistances. It was associated with R factor deoxyribonucleic acid in membrane-deoxyribonucleic acid complexes. Its possible role in R factor replication and/or transfer is being investigated.

A simple rapid method for the removal of leukocytes from human blood.

Filtration of human blood cells through lamb's wool columns removed more than 96% of all leukocytes in a series of experiments, while the retention of erythrocytes by the column averaged 6.4%. This method should prove extremely useful for obtaining pure erythrocyte preparations for use in biochemical and physiological studies, and for removing leukocytes from blood prior to transfusion.

Human leprosy in normal mice.

It has now been shown that normal mice can be used as models for studying the early stages in the development of leprosy. Inoculation into the foot pads of mice of as few as 10(4) leprosy bacilli leads to infections which spread to distant sites via the blood stream and after two or more years give rise to granulomata and neural damage at the sites of inoculation. Where the tissue response had fully developed it reproduced exactly the histological features of human leprosy in the borderline range.
