How is Actinomyces transmitted?
It is presumed that Actinomyces can be transmitted from person-to-person via direct contact as part of the normal oral flora 7.
Is Actinomyces catalase positive or negative?
Actinomyces oricola They are catalase negative and facultatively anaerobic but grow best under anaerobic conditions. The end products of glucose metabolism are acetic, lactic and succinic acids. They are also negative for gelatin and starch hydrolysis and positive for aesculin hydrolysis.
What disease does Actinomyces cause?
Actinomycosis is a chronic localized or hematogenous anaerobic infection caused by Actinomyces israelii and other species of Actinomyces. Findings are a local abscess with multiple draining sinuses, a tuberculosis-like pneumonitis, and low-grade systemic symptoms.
Which region is most commonly affected in actinomycosis?
It normally does not cause disease. Because of the bacteria’s normal location in the nose and throat, actinomycosis most commonly affects the face and neck. The infection can sometimes occur in the chest (pulmonary actinomycosis), abdomen, pelvis, or other areas of the body. The infection is not contagious.
Which areas of the body can be affected by actinomycosis infection?
Actinomycosis is usually caused by the bacterium called Actinomyces israelii. This is a common organism found in the nose and throat. It normally does not cause disease. Because of the bacteria’s normal location in the nose and throat, actinomycosis most commonly affects the face and neck.
What kind of infection actinomycosis is?
Actinomycosis is a rare chronic disease caused by Actinomyces spp., anaerobic Gram-positive bacteria that normally colonize the human mouth and digestive and genital tracts.
Which form of actinomycosis is most common?
Cervicofacial actinomycosis is the most frequent clinical form of actinomycosis, and “lumpy jaw syndrome”, which is associated with odontogenic infection, is the most common clinical manifestation (see “Case 3”), representing approximately 60% of all reported cases.
Is actinomycosis painful?
The lump itself isn’t typically painful. However, it can result in a painful skin abscess that first appears as a reddish bruise at the site. Actinomycosis can also cause muscle spasms in the jaw or a “locked jaw.” If this happens, the mouth cannot open in a normal way.
Is Actinomyces serious?
Actinomycosis is a rare type of bacterial infection. It can be very serious but can usually be cured with antibiotics.
