Actinomyces-associated lesions in the jaw, such as radicular cyst and osteomyelitis, have been reported by many authors. The lesions are caused by infection from peripheral sites and can be seen to contain Actinomyces druses on pathologic examination. To our knowledge, no previous reports have described Actinomyces-associated calcification in the jaw, although the lesions in the jaw often inclu...
Eight strains of a previously undescribed catalase-negative Actinomyces-like bacterium were recovered from human clinical specimens. The morphological and biochemical characteristics of the isolates were consistent with their assignment to the genus Actinomyces, but they did not appear to correspond to any recognized species. 16S rRNA gene sequence analysis showed the organisms represent a hith...
Actinomycosis is a chronic infection caused by Actinomyces species characterized by abscess formation, tissue fibrosis, and draining sinuses. The spectrum of infections caused by Actinomyces species ranges from classical invasive actinomycosis to a less invasive form of superficial skin and soft tissue infection. We present a review detailing all Actinomyces species isolated from breast infecti...
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 ...
Primary sternal osteomyelitis is a rare disease. Common infectious organisms causing primary sternal osteomyelitis include Staphylococcus aureus and Pseudomonas aeruginosa. Actinomyces species are common saprophytes of the oral cavity, but there have been few reports in the literature of primary sternal osteomyelitis caused by Actinomyces species. We describe a case of primary sternal osteomyel...
Actinomyces rarely causes endocarditis with 25 well-described cases reported in the literature in the past 75 years. We present a case of prosthetic valve endocarditis (PVE) caused by Actinomyces naeslundii. To our knowledge, this is the first report in the literature of endocarditis due to this organism and the second report of PVE caused by Actinomyces.
Actinomyces sp. strain Chiba101, isolated from an arthritic leg joint of a pig raised in Japan, is a bacterium closely related to Actinomyces denticolens Here, we deciphered the complete genome sequence of Actinomyces sp. Chiba101 and the high-quality draft genome sequence of A. denticolens DSM 20671T.
We report a case of broncholithiasis secondary to pulmonary actinomycosis. Broncholithiasis has occasionally been reported in association with actinomycosis, but it is unclear if actinomycosis leads to lymph node calcification with subsequent erosion into the airway, producing a broncholith, or if an existing generic broncholith is secondarily colonized with Actinomyces. The patient had post-ob...
King, Sylvia (Hektoen Institute, Chicago, Ill.) and Esther Meyer. Gel diffusion technique in antigen-antibody reactions of Actinomyces species and "anaerobic diphtheroids." J. Bacteriol. 85:186-190. 1963.-The Ouchterlony agar gel diffusion test was used to establish antigenic patterns produced by Actinomyces israelii, A. bovis, and A. naeslundii, as compared with those of "anaerobic diphtheroid...
