Screening for Corynebacterium diphtheriae.
A throat swab from a 9 year old girl with pharyngitis yielded a non-toxigenic strain of Corynebacterium diphtheriae var mitis and Streptococcus group G. C pseudodiphtheriticum was isolated from the throats of two of her four brothers. In each case the isolate was sent to the reference laboratory before full identification. The growth was found to be mixed for one brother; the other isolate bein...

متن کاملToxinogeny in Corynebacterium diphtheriae.
In 1951, Freeman made the remarkable discovery that nontoxinogenic Corynebacterium diphtheriae became toxinogenic2 after association with the lytic phage B, previously described by Toshach (1950). From lysates of nontoxinogenic, nonlysogenic C. diphtheriae, Freeman and Morse (1951) established, through the isolation of single cells, lysogenic strains which were toxinogenic. The lysogenic clones...
متن کاملNeuraminidase of Corynebacterium diphtheriae.
Neuraminidase activity has been found in a variety of strains of Corynebacterium diphtheriae, both toxinogenic and nontoxinogenic. The enzyme has been shown to be intracellular, possibly associated with the cytoplasmic membrane. Toxinogenic strains of the diphtheria bacillus, grown under conditions unsuitable for maximal toxin production, produce neuraminidase, and the enzyme has been purified ...
متن کاملSialidase (neuraminidase) of Corynebacterium Diphtheriae.
Warren, Leonard (National Institute of Arthritis and Metabolic Diseases, Bethesda, Md.) and C. W. Spearing. Sialidase (neuraminidase) of Corynebacterium diphtheriae. J. Bacteriol. 86:950-955. 1963.-The characteristics of a sialidase produced by Corynebacterium diphtheriae were studied. The enzyme was partially purified from preparations of diphtheria toxin on a column of Sephadex G-75. By this ...
