Here, we present the complete genome sequence of Actinomyces naeslundii strain ATCC 27039, isolated from an abdominal wound abscess. This strain is genetically transformable and will thus provide valuable information related to its crucial role in oral multispecies biofilm development.

different types of actinomyces spp isolated from the oral cavity of human in healthy as well as in pathological state. internally it is only found in association with pathological organs. recently actinomyces naeslundii has been isolated from blood culture of a leukemic patient. present studies indicate the association of this microorganism with cells obtained from bone marrow by punction in mo...

Actinomyces glycerinitolerans strain G10T, which was isolated from sheep rumen fluid, can metabolize a range of substrates, including complex carbohydrates to organic acids (OAs). Here, we report a 3.69-Mbp draft genome of Actinomyces glycerinitolerans.

Bacteriol. 88:477-490. 1964.-Four unusual isolates of Actinomyces species were compared with six control strains of well-identified Actinomyces species. Their oxygen requirements and their morphological and biochemical characteristics were det...

OBJECTIVES To assess antimicrobial activities of aqueous crude khat (Catha edulis) extracts against a panel of oral microorganisms and to test their ability to modify bacterial resistance to tetracycline and penicillin in vitro. DESIGN Lyophilized aqueous extracts were prepared from three khat cultivars. The agar dilution method of the NCCLS was used to test the extracts, at concentrations of...

BACKGROUND The studies of the distribution of Actinomyces spp. on carious and non-carious root surfaces have not been able to confirm the association of these bacteria with root caries, although they were extensively implicated as a prime suspect in root caries. OBJECTIVE The aim of this study was to observe the gene expression of Actinomyces spp. in the microbiota of root surfaces with and w...

BACKGROUND Actinomyces are a common part of the residential flora of the human intestinal tract, genitourinary system and skin. Isolation and identification of Actinomyces by conventional methods is often difficult and time consuming. In recent years, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) has become a rapid and simple method to identify bact...
