Actinomycosis is most frequently caused by A. israelii, which may also cause endocarditis, though the resulting symptoms may be similar to those resulting from infections by other bacterial species. [ 8 ] [ 9 ] Aggregatibacter actinomycetemcomitans has been identified as being of note in periodontal disease , especially aggressive and localized ...
Actinomycosis is a rare infectious bacterial disease caused by the gram-positive Actinomyces species. [1] The name refers to ray-like appearance of the organisms in the granules. About 70% of infections are due to either Actinomyces israelii or A. gerencseriae. [1] Infection can also be caused by Streptomyces somaliensis and Propionibacterium ...
Actinomycosis is most frequently caused by A. israelii. [4] It is a normal colonizer of the vagina, [5] colon, and mouth. [6] Infection is established first by a breach of the mucosal barrier during various procedures (dental, gastrointestinal), aspiration, or pathologies such as diverticulitis. [7]
Actinomycetoma is a chronic bacterial subcutaneous infection caused by Actinomyces that affect the skin and connective tissue. [1] It is, therefore, a form of actinomycosis . [ 2 ] Mycetoma is a broad term which includes actinomycetoma and eumycetoma under it.
Schaalia turicensis (formerly Actinomyces turicensis) is a Gram-positive bacterium found in the flora of the oral cavity, gut, skin, and female urogenital tract. [2] S. turicensis is an important human pathogen of soft tissue infections in the lower body. [3] S. turicensis is a facultative anaerobe, growing in air and CO 2 conditions.
It is one of the bacteria that might be implicated in destructive periodontal disease. Although it has been found more frequently in localized aggressive periodontitis, [3] prevalence in any population is rather high. It has also been isolated from actinomycotic lesions (mixed infection with certain Actinomyces species, in particular A. israelii).
Cutaneous actinomycosis is a chronic disease that affects the deep subcutaneous tissue of the skin. Caused by an anaerobic, Gram-positive, filamentous type of bacteria in the genus Actinomyces, [1]: 270 invasion of the soft tissue leads to the formation of abnormal channels leading to the skin surface (external sinus tracts) that discharge pale yellow sulfur granules.
A. viscosus infection symptoms are indistinguishable from Actinomyces israelii infection symptoms or Actinomyces bovis infection symptoms. [1] A. israelii and A. bovis infections usually cause actinomycotic infections, but sometimes and very rarely will the pathogen be A. viscosus. [1] A. viscosus colonies test positive for catalase and ...
