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]

2023年5月9日 · 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. But surgery, injury or disease can cause them to grow in places they don’t belong.

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.

2024年9月19日 · Severe or extensive actinomycosis – Severe, extensive infection is often invasive and associated with significant purulence or fistulous tracts, and often occurs in patients with significant underlying comorbidities.

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.

2022年9月18日 · Actinomycosis is a long-term infection that causes sores, or abscesses, in the body’s soft tissues. Actinomycosis is usually found in the: Actinomycosis rarely appears elsewhere in the...

Actinomycosis is an infrequent invasive bacterial disease that has been recognized for over a century. Actinomyces spp. are filamentous Gram-positive bacilli, mainly belonging to the human commensal flora of the oropharynx, gastrointestinal tract, and urogenital tract.

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.

Actinomycosis is defined as a hard mass-type lesion with a specific histopathological structure. There are a large number of case reports of actinomycosis in the literature, but in most cases, diagnosis has been based solely on clinical and histopathological findings.

Actinomycosis is a chronic or slowly progressive infection caused by various bacterial species of the Actinomyces genus, most commonly Actinomyces israelii. Actinomyces are normal inhabitants of the mouth, gastrointestinal tract, and female genital tract, and do not cause an infection unless there is a break in the skin or mucosa.
