1. The concentrations of reduced ascorbic acid present in the tissues of normal rhesus monkeys are of a magnitude in keeping with the values found for other animal species which are incapable of synthesizing vitamin C. These concentrations are subject to distinct increase by prolonged parenteral administration of ascorbic acid. 2. The amounts of vitamin C(More)
1. Murine SK poliomyelitis virus has been transferred from mouse to guinea pig with the establishment of a fixed strain of cavian passage virus. 2. The disease thus produced in guinea pigs is characterized by the occurrence of flaccid paralysis. Typical poliomyelitic lesions are found in the anterior horn of the spinal cord. 3. Guinea pigs are susceptible(More)
Although hydroxyurea (HU) is recognized as a specific inhibitor of deoxyribonucleic acid (DNA) synthesis, it did not have this effect in a strain of Staphylococcus epidermidis. In this case, HU caused a loss of colony-forming ability but did not prevent cell division in liquid medium. DNA synthesis apparently was affected only secondarily. About 10% of the(More)

Bacteriol. 91:1239-1247. 1966.-Changes in ultraviolet (UV) sensitivity of phage-host complexes during phage development have been studied for the following systems: T1 and Escherichia coli B, T1 and E.(More)
1. SK murine virus maintained over more than 200 serial mouse passages increased in virulence for mice from an initial intracerebral titer of about 1:1 million to a maximum titer of not less than 1:1 billion dilution activity. 2. Following intracerebral injection with murine virus of remote mouse passages, 5 of 13 rhesus monkeys developed a characteristic(More)
