Septicaemia due to Corynebacterium haemolyticum.
The clinical and microbiological features of a case of septicaemia due to Corynebacterium haemolyticum are described. Isolation of the organism from blood cultures taken at the time of admission, immediate response to penicillin, presence of agglutinating antibodies in high titre in the patient's serum, and our failure to find evidence of infection with any other pathogen suggests a causative r...
متن کاملArcanobacterium haemolyticum phospholipase D is genetically and functionally similar to Corynebacterium pseudotuberculosis phospholipase D.
Arcanobacterium haemolyticum, a pathogen of the human upper respiratory tract and other systems, has been reported to produce soluble toxins, including a phospholipase D (PLD). We confirmed production of PLD by this organism and cloned and sequenced pld. Arcanobacterial PLD (PLD-A) was found to be a protein of approximately 31.5 kDa with a pI of approximately 9.4. Cosmid cloning, followed by su...
متن کاملHemin-dependent growth stimulation and cytochrome synthesis in Corynebacterium pyogenes.
Growth of Corynebacterium pyogenes, an important pathogen in animals, was greatly increased on addition of hemin to a medium of tryptose plus mineral. The synthesis of a type b cytochrome in this organism appeared to depend on the presence of hemin in the growth medium.

متن کاملAlpha-mannosidase: a rapid test for identification of Arcanobacterium haemolyticum.
A 4-h alpha-mannosidase test for identification of Arcanobacterium haemolyticum strains (n = 139) and differentiation of A. haemolyticum from Actinomyces pyogenes strains (n = 30) and other gram-positive rods was evaluated. Practically all A. haemolyticum strains (138 of 139) and the Listeria monocytogenes type strain were alpha-mannosidase positive, while all A. pyogenes strains and Corynebact...
