positive Lyme disease serology in human granulocytic ehrlichiosis. Corynebacterium pseudogenitalium Urinary Tract Infection To the Editor: A 64-year-old man was admitted to the urology department of Cochin Hospital in Paris, France, for acute urinary retention. He had a history of recurrent urolithiasis and undocumented urinary tract symptoms. At admission, a urethral catheter was inserted, and...

In a previous paper (Hirose et al., 1962) it was reported that guinea pigs highly immunized against a bacterial suspension of Corynebacterium diphtheriae resisted to a challenge by the conjunctival method (Murata et al., 1959) with a toxinogenic virulent strain without even traces of antitoxic immunity, while a passive transfer of the immunity failed. The reason for this failure may have been d...

BACKGROUND L-Ornithine is a non-protein amino acid with extensive applications in medicine and the food industry. Currently, L-ornithine production is based on microbial fermentation, and few microbes are used for producing L-ornithine owing to unsatisfactory production titer. RESULTS In this study, Corynebacterium glutamicum S9114, a high glutamate-producing strain, was developed for L-ornit...

Corynebacterium jeikeium, a resident of human skin, is often associated with multidrug resistant nosocomial infections in immunodepressed patients. C. jeikeium K411 belongs to mycolic acid-containing actinomycetes, the mycolata and contains a channel-forming protein as judged from reconstitution experiments with artificial lipid bilayer experiments. The channel-forming protein was present in de...

Corynebacterium renale type I (strain 115), 1.7 x 107 to 4.5 x 107 organisms, introduced intravenously into mice disappeared from the blood less than 24 h after inoculation and did not produce pyelonephritis. The same strain, 1 x 107 to 5 x 107 organisms, inoculated into the urinary bladder of mice was not recovered from the blood in any of the mice, but caused pyelonephritis accompanied by ure...

Five clones of the Park-Williams number 8 strain of Corynebacterium diphtheriae, previously maintained in separate laboratories, were examined for their colonial and biochemical properties, for the restriction and modification system which operates to obscure their lysogeny, and for their capacity to produce large amounts of toxin under ordinary laboratory conditions. The phenotypes of their ph...
