Actinomyceslymphadenitis [PDF]

Baylor University Medical Center Proceedings, 2020
Actinomyces is a gram-positive anaerobe that colonizes the human oral cavity. Its pathogenesis involves the disruption of the mucosal membrane, leading to suppuration and subsequent abscess formation, most commonly in the cervicofacial region. The bacteria form masses consisting of aggregates of branching, filamentous bacilli.

Application of MLST and Pilus gene sequence comparisons to investigate the population structures of Actinomyces naeslundii and Actinomyces oris [PDF]

, 2011
Actinomyces naeslundii and Actinomyces oris are members of the oral biofilm. Their identification using 16S rRNA sequencing is problematic and better achieved by comparison of metG partial sequences. A.

Production of Endoglucanases by Streptomyces thermocoprophilus CP1 using Rice Straw as a Substrate

Journal of Pure and Applied Microbiology, 2021
Rice straw is a major agricultural waste that can be used as an alternative substrate to expensive raw materials for endoglucanases (CMCase) production by microorganisms.

More than Valley Fever: Pulmonary Actinomycosis and Coccidioidomycosis Co-infection in a Patient

European Journal of Case Reports in Internal Medicine, 2021
Pulmonary coccidioidomycosis and pulmonary actinomycosis are unheard of as co-pathogens. Infection with these organisms on their own can mimic lung cancer, thus presenting a diagnostic challenge. We present the case of a 75-year-old woman presenting with

Mannose-contaminating agglutinin for Actinomyces viscosus and Actinomyces naeslundii [PDF]

Infection and Immunity, 1979
Rapid agglutination of Actinomyces viscosus and Actinomyces naeslundii cells by D-mannose solutions was observed during studies of their attachment to mammalian cells in vitro. The specificity of the agglutination reaction was studied by slide agglutination tests and by measuring the rate of decrease in optical density of bacterial phosphate buffer ...

Implantable cardioverter defibrillator related Actinomyces Odontolyticus endocarditis and bacteremia—First reported case

IDCases, 2021
Actinomyces Odontolyticus is a gram-positive bacillus, usually found in the oropharynx, gastrointestinal and urogenital tracts, as commensal flora. Infections caused by this organism are rare but may occur, more commonly in immunocompromised patients. We

Multiple lung abscesses caused by Actinomyces graevenitzii mimicking acute pulmonary coccidioidomycosis [PDF]

, 2012
Actinomyces graevenitzii is a newly recognized Actinomyces species that is seldom isolated from clinical specimens. A case of multiple pulmonary abscesses mimicking acute pulmonary coccidioidomycosis is described in this study, and the findings indicate ...

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

Periodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Clinical periodontal diagnosis

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Prevention of Initial Bacterial Attachment by Osteopontin and Other Bioactive Milk Proteins

Biomedicines, 2022
A considerable body of work has studied the involvement of osteopontin (OPN) in human physiology and pathology, but comparably little is known about the interaction of OPN with prokaryotic cells.
