Many Actinomyces species are part of the oral microflora of humans. Actinomyces odontolyticus associated infections are exceptionally rare, presenting an endogenous infection originating from mucous membranes. Immunodeficiency is often complicated by severe opportunistic bacterial infections leading to critical condition of the patient. We report a case of an immunosuppressed patient with fever...
OBJECTIVE To assess various methods of management of actinomyces-like organisms associated with intrauterine devices. METHODS A retrospective chart review of 173 patients with intrauterine device-associated actinomyces- like organisms detected on Pap smear was performed. The patients were managed by IUD removal with or without antibiotic therapy, antibiotic therapy alone, or no treatment at a...
A novel, Gram-staining-positive, facultatively anaerobic, non-motile and coccus-shaped bacterium, strain WL80(T), was isolated from the gut of an abalone, Haliotis discus hannai, collected from the northern coast of Jeju in Korea. Optimal growth occurred at 30 °C, pH 7-8 and with 1% (w/v) NaCl. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that strain WL80(T) fell within th...
Spontaneous Bacterial Peritonitis due to Actinomyces Mimicking a Perforation of the Proximal Jejunum
BACKGROUND Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to diversity in clinical and radiological presentation, actinomycosis can easily be mistaken for seve...
Bacterial colonies, foreign bodies or other artifacts in tonsil specimens are identified as incidental findings. Actinomyces are relatively often encountered on histological examination of tonsils. Actinomyces israeli and Actinomyces naeslundi are the most frequently isolated pathogenic Actinomycetes. They are Gram positive, anaerobic, non acid fast, branching, filamentous and slow growing bact...
Buchanan, B. B. (Duke University, Durham, N.C.), and Leo Pine. Relationship of carbon dioxide to aspartic acid and glutamic acid in Actinomyces naeslundi. J. Bacteriol. 89:729-733. 1965.-CO(2), which was essential for the fermentation of glucose to succinic acid by Actinomyces naeslundii, was also required for the synthesis of internal aspartic acid, for which the cells lack a permease.
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 that this organism is an opportunistic human pathogen.
