Actinomyces - Wikipedia
Actinomyces is a genus of the Actinomycetia class of bacteria. They all are Gram-positive and facultatively anaerobic, growing best under anaerobic conditions. [2] Actinomyces species may form endospores, and while individual bacteria are rod-shaped, Actinomyces colonies form fungus-like branched networks of hyphae. [3]
Actinomycosis: Causes, Symptoms, Diagnosis & Treatment
2023年5月9日 · Overview. What is actinomycosis? Actinomycosis (pronounced “ack-tin-oh-my-COH-sis”) is a rare bacterial infection that causes pus-filled areas (abscesses) surrounded by bumpy tissue. You get it from bacteria of the genus Actinomyces. Actinomyces live naturally in your body without harming you.
Treatment of actinomycosis - UpToDate
2024年9月19日 · Management of actinomycosis often entails prolonged courses of antimicrobials. Surgical intervention may also be necessary in more complicated cases, such as infection in critical spaces (eg, epidural infections, brain abscesses), patients with massive hemoptysis, or when extensive abscesses and fistulous tracts are present.

2023年8月7日 · Actinomycosis is a rare subacute to chronic infection caused by the gram-positive filamentous non-acid fast anaerobic to microaerophilic bacteria, Actinomyces. The infection is usually a granulomatous and suppurative infection.

2023年2月8日 · Actinomyces spp. reside on mucosal surfaces and gain access to deeper tissues via surgical procedures, trauma, etc., disrupting the mucosal barrier. The main niche is the oral cavity/pharynx. Also, in GI (distal esophagus), GU tract.
Actinomycosis: Microbiology, epidemiology, clinical ... - UpToDate
Actinomycosis is an infection characterized by abscess formation, induration, draining sinus tracts, fistulae, and tissue fibrosis. It can mimic several other conditions, particularly malignancy and granulomatous disease.
Actinomycetes : A Never-Ending Source of Bioactive …
Actinomyces were sources of very large numbers of natural and semisynthetic antibiotics and are producers of secondary metabolites whose chemical structures have inspired the discovery of new fully synthetic antibiotics.
Actinomyces and Related Organisms in Human Infections
A wide range of Actinomyces species are being increasingly associated with infections at many body sites (11, 13, 14). Actinomyces meyeri, Actinomyces neuii, and Actinomyces turicensis are emerging as important causes of such infections.
Actinomyces - an overview | ScienceDirect Topics
Actinomyces are endogenous commensals of the mouth, throat, GI tract, and vagina. They are gram-positive, branching, filamentous bacilli that are weakly pathogenic and usually infect previously traumatized or injured tissue.
Actinomyces - an overview | ScienceDirect Topics
Actinomyces species are pathogenic locally in the oral cavity or through direct extension into fascial planes as abscesses. Of the myriad species of Actinomyces identified, the most common pathogens include A. israelii, A. viscosus, A. naeslundii, A. turicensis, and A. radingae.
