Isolation of Actinomyces bacteriophage from human dental plaque.
Human dental plaque samples were screened for the presence of bacteriophage for Actinomyces viscosus and Streptococcus sanguis. None of the 336 samples yielded phage for S. sanguis, but 10 contained virulent actinomyces phage. A high host cell specificity was observed in that one phage isolate infected only A. viscosus T14V, eight phage isolates infected only A. viscosus MG-1, and one infected ...
متن کاملDifferential 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 کاملActinomyces denticolens colonisation identified in equine tonsillar crypts
Recently, submandibular abscesses associated with Actinomyces denticolens have been reported in horses. The actinomycotic clumps have been observed in the tonsillar crypts. The aim of this study was to demonstrate colonisation of A denticolens in equine tonsils. Twelve equine tonsils obtained from a slaughterhouse were divided into two parts for histopathological examination and for isolation o...
متن کاملDevelopment of a selective medium for detection and enumeration of Actinomyces viscosus and Actinomyces naeslundii in dental plaque.
A selective medium (CFAT) was developed for the detection and enumeration of Actinomyces viscosus and Actinomyces naeslundii in dental plaque. Neutral acriflavin and potassium tellurite were used in combination with the known selective agents cadmium and fluoride to eliminate most of the competing plaque flora. Composition of CFAT per liter was as follows: Trypticase soy broth (BBL Microbiology...
متن کاملThe relation between Actinomyces and denture stomatitis
Abstract Background & Aim: Denture induced stomatitis occurs in 24-60 percents of edentulous people who have dentures.Up to now some etiologic factors have been introduced for denture stomatitis but there are some controversies.In some literatures some other microorganisms have been isolated besides candida albicans as main reasons. According to the incidence of denture induced stomatitis an...
