It is a chronic inflammatory disease caused by the blockage of pilosebaceous units causing inflammatory lesions, non-inflammatory lesions or a mixture of both on the face, neck and/or chest. [10] [11] Acne vulgaris cannot be defined as an infectious disease since the bacteria is found on a vast majority of individuals without causing lesions. [10]
Actinomyces species may form endospores, and while individual bacteria are rod-shaped, Actinomyces colonies form fungus-like branched networks of hyphae. [3] The aspect of these colonies initially led to the incorrect assumption that the organism was a fungus and to the name Actinomyces , "ray fungus" (from Greek actis , ray or beam, and mykes ...
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 ...
Infectious agent Common name Diagnosis Treatment Vaccine(s) Acinetobacter baumannii: Acinetobacter infections Culture Supportive care No Actinomyces israelii, Actinomyces gerencseriae and Propionibacterium propionicus: Actinomycosis: Histologic findings Penicillin, doxycycline, and sulfonamides: No Adenoviridae: Adenovirus infection
But chronic inflammation, which builds up over years, can damage tissue and organs, leading to health issues such as type 2 diabetes, rheumatoid arthritis, and cardiovascular disease. So, you may ...
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 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 ]
While many of these cause disease in humans, Streptomyces is notable as a source of antibiotics. [10] Of those Actinomycetota not in the Actinomycetales, Gardnerella is one of the most researched. Classification of Gardnerella is controversial, and MeSH catalogues it as both a Gram-positive and Gram-negative organism. [17]
