Differential medium for detecting dental plaque bacteria resembling Actinomyces viscosus and Actinomyces naeslundii.
A medium for detecting colonies of Actinomyces viscosus and Actinomyces naeslundii in dental plaque samples was developed. The medium (CNAC-20) contains 20.0 mug of 3CdSO4-8H2O per ml of Columbia CNA agar base. Laboratory strains of A. viscosus grew on CNAC-20 in characteristic round, white, smooth, opaque colonies. Increasing the cadmium concentration impaired the growth of some A. viscosus st...
متن کاملFailure of an Actinomyces pyogenes vaccine to protect sheep against an intravenous challenge.
The immunity conferred by an A. pyogenes bacterin-toxoid was evaluated in sheep, using an intravenous challenge system. Three sheep were vaccinated and 3 served as controls. The vaccinated sheep were not protected against pyogenic conditions. High antitoxin levels were induced by vaccination but could not be associated with protection against infection. Antibacterial antibody levels elicited wi...
متن کاملInterbacterial adherence between Actinomyces viscosus and strains of Streptococcus pyogenes, Streptococcus agalactiae, and Pseudomonas aeruginosa.
Interbacterial adherence was sought between strains of Actinomyces viscosus indigenous to the human mouth and strains of Streptococcus pyogenes, Streptococcus agalactiae, and Pseudomonas aeruginosa. Six of nine strains of S. pyogenes, three of five strains of S. agalactiae, and two of four strains of P. aeruginosa were found to coaggregate with each of five strains of A. viscosus tested. Some c...
متن کاملIdentification of Actinomyces (Corynebacterium) pyogenes with the API 20 Strep system.
A total of 62 strains of Actinomyces pyogenes (previously Corynebacterium pyogenes) were examined by the API 20 Strep system (API System, La Balme Les Grottes, Montalieu-Vercieu, France). The system was shown to be reliable and rapid when the tests were compared with standard identification methods. No confusion occurred with streptococcal profiles in the current API 20 Strep data base.
متن کاملThe Arcanobacterium (Actinomyces) pyogenes hemolysin, pyolysin, is a novel member of the thiol-activated cytolysin family.
Arcanobacterium (Actinomyces) pyogenes, an animal pathogen, produces a hemolytic exotoxin, pyolysin (PLO). The gene encoding PLO was cloned, and sequence analysis revealed an open reading frame of 1,605 bp encoding a protein of 57.9 kDa. PLO has 30 to 40% identity with the thiol-activated cytolysins (TACYs) of a number of gram-positive bacteria. The activity of PLO was found to be very similar ...
