The Effect upon Micrococcus Violagabriellae of Short-term Exposure to Ultraviolet Light.
The presence of inorganic or organic iron in the growth medium induces the production of a reddish-violet pigment in Micrococcus violagabrielhe. This pigment protects the organism against short exposures to ultraviolet (u.v.) radiation of wavelength below 300 mp. The presence of iron also increases the degree of recovery of the normally white organism after such irradiation. Anaerobic growth re...
متن کاملViolagabriellae variant of Staphylococcus epidermidis on normal human skin.
Twenty-seven strains of a reddish violet pigment-producing variety of Staphylococcus epidermidis have been recovered from normal human skin. They closely resemble the previously unique Castellani strain, named Micrococcus violagabriellae, which was placed by K. J. Steel in S. epidermidis. These strains are classified as S. epidermidis by using the Baird-Parker schema; however, besides the pigme...

متن کاملThe pigments of Micrococcus tetragenus: VI. Micrococcus Tetragenus Infection.
A pattern of variation of Micrococcus tetragenw9 (Reimann, 1936 a, b), the transformation of its bacterial types (Reimann, 1937 a), and the significance of bacterial variation (Reimann, 1937 b,) were described and discussed in a series of papers published in this Journal. A strain of M. tetragenus isolated from the blood of a patient produced white colonies on agar, (Reimann, 1935). During the ...
