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 ...
bovine actinomycosis, 3-year-old bull, 2-month evolution bony swelling of the right maxillae thick matter (top) and old fistulous granulomas. Actinomycosis is an infection caused by a bacterium of the genus Actinomyces, usually Actinomyces bovis; the disease it causes has several common names. When it is a moveable tumour or lump on the jaw ...
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 ]
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 ...
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 .
Actinomyces viscosus is a human and animal pathogen/pathobiont which colonises the mouths of 70% of adult humans. [1] A. viscosus has a low level of virulence and is often mistaken with other actinomycetes .
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]
Humans can also get this skin disease if elementary hygiene measures are not observed after dealing with infected animals. This dermatologic condition is known by many names - cutaneous streptotrichosis (on cattle, goats, and horses), rain scald (on horses), lumpy wool (on sheep), and strawberry foot rot.
