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 ...
Symptoms include fever, abdominal pain, and weight loss. [11] Actinomyces species have also been shown to infect the central nervous system in a dog "without history or evidence of previous trauma or other organ involvement." [12] Pelvic actinomycosis is a rare but proven complication of use of intrauterine devices. In extreme cases, pelvic ...
Actinomyces bovis is a branching, Gram-positive, rod-shaped bacterium of the genus Actinomyces. [1] It is the causative agent of lumpy jaw in cattle, and occasionally causes actinomycosis infections in humans. [ 3 ]
Actinomyces israelii is a species of Gram-positive, rod-shaped bacteria within the genus Actinomyces. Known to live commensally on and within humans, A. israelii is an opportunistic pathogen and a cause of actinomycosis .
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 ...

Additionally, Actinomyces have been identified as important members of the human microbiome, residing in various sites such as the oral cavity (mouth, pharynx, esophagus) and gastrointestinal tract. [9] While some Actinomyces species are commensal, others can cause opportunistic infections in humans, commonly Actinomycosis. [9]
Actinomyces spp. and Eubacterium nodatum are often recovered in infections associated with intrauterine devices. Mobiluncus spp. can be associated with bacterial vaginosis. [ 34 ] The aerobic bacteria also found mixed with these anaerobic bacteria include Enterobacteriaceae, Streptococcus spp. (including groups A and B), Neisseria gonorrhoeae ...
