Gram-positive, non-spore-forming rods (strain 4401292T) were isolated from a human blood sample. Based on cellular morphology and the results of biochemical tests, this strain was tentatively identified as belonging to an undescribed species of the genus Actinomyces. Phylogenetic analysis based on ...

On the basis of the phylogenetic analysis, the novel species Actinomyces polynesiensis str. MS2 sp. nov. is proposed with the accession number CCXH01000000 in the GenBank database. Genome Sequence Accession Number The genome of Actinomyces polynesiensis str. MS2 has been submitted to the EBI...
Itzhak Brook, in Principles and Practice of Pediatric Infectious Disease (Third Edition), 2008 ACTINOMYCES SPECIES Actinomyces species are filamentous, branching, gram-positive, pleomorphic non-spore-forming, non-acid-fast anaerobic or microaerophilic bacilli. On Gram stain, Actinomyces cannot be disting...

Actino myces species are now recognised as gram-positive bacilli which can occur singly, in pairs or in chains and are non acid-fast, non-motile, obligate or facultative anaerobes. Characteristically they are seen as branching filaments on gram staining. They are members of the bacterial...
In our case, brain abscess was likely due to spread of Actinomyces meyeri from oral cavity to brain parenchyma. The oral cavity harbors more than 500 bacterial species. Just 1 mg of dental plaque may contain more than 1011 microorganisms. Most oral microorganisms are harmless, but if the pa...
There are few studies describing the use of MALDI-TOF MS MIS in identifyingA. neuii. One other study showed that the VITEK MS system was able to correctly identifyA. neuiito the species level in eight of 12 instances [21]. Three groups used Bruker MALDI-TOF MS MIS (Bruker, Billerica,...
The cell wall is composed of peptidoglycan that contains alanin, lysine and d-glutamic acid, but some species also have either ornithine (configuration A5α) or d-aspartic acid (configuration A5β). None possess diaminopimelic acid nor mycolic acids or glycin in their cell walls. A variety ...
Actinomyces turicensis is an isolate that has emerged recently to cause infections in humans. There are few reported cases of this species causing abdominal and genital infections; however, there is no report of it invading the cervicofacial space. A feared complication of Ludwig’s angina and ...
