What is the difference between actinomycosis and Actinomycetoma?
Actinomycosis is to be differentiated from actinomycetoma, which is a chronic infection of the skin and subcutaneous tissue, usually involving the foot (see mycetoma). Actinomycetoma is caused by different species of Actinomyces that are found in soil and plant material in tropical regions.
What is the difference between Streptomyces and Actinomyces?
Actinomyces are anaerobic, while Nocardia and Streptomyces are aerobic. Nocardia stain partially acid-fast, Actinomyces and Streptomyces are not acid-fast. Actinomyces and Streptomyces produce granules. Most actinomycetes in tissue do not stain with the H & E stain commonly used for general histopathology.
What is the most common type of actinomycosis?
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.
Why is actinomycosis called lumpy jaw?
Actinomycosis, commonly called ‘Lumpy Jaw’, is caused by the bacteria Actinomyces bovis, which is a normal inhabitant of the bovine mouth. Actinomycosis is a chronic bacterial disease and is more common in cattle than in goats and sheep.
How does actinomycosis spread?
If something sharp pierces the internal body tissues, such as a fish bone in the esophagus, the bacteria can spread. Actinomycosis can also happen if there is tooth decay or gum disease.
Why is it called Madura foot?
The first modern description of Madura foot was made in 1842 from Madurai (the city after which the disease was named Madura-mycosis) in India, by Gill. The fungal cause of the disease was established in 1860 by Carter.
How do I know if I have actinomycetes colony?
Actinomycetes form colonies that are leathery and many produce pigments and they have earthy smell. If you look under the microscope you will easily see the spores and you will easily recognize the corkscreww shape of streptomyces. In the litterature many culture media are descibed for isolation of actinomycetes.
How do you get actinomycosis?
If something sharp pierces the internal body tissues, such as a fish bone in the esophagus, the bacteria can spread. Actinomycosis can also happen if there is tooth decay or gum disease. As the infection progresses, painful abscesses can form and grow in size.
How do you test for actinomycosis?
To diagnose actinomycosis, a doctor may take a sample of sputum, pus, or tissue to send for microscopic investigation in a laboratory. Sometimes, the laboratory will make a culture of the bacteria. If the infection is present, the pus or tissue will usually contain yellow sulfur granules.
