What is actinomycosis in cattle?
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.
What causes actinomycosis in cow?
A bovis is part of the normal oral flora of ruminants. Disease is seen when A bovis is introduced to underlying soft tissue via penetrating wounds of the oral mucosa from wire or coarse hay or sticks.
How do you control actinomycosis?
One of the best ways to prevent actinomycosis is to practice good oral hygiene. Schedule regular visits with your dentist so that they can spot potential problems. If you get proper treatment for actinomycosis, it’s highly curable and you’ll likely make a full recovery.
Is Actinomyces Bovis zoonotic?
It is important to note that Actinomyces bovis is a zoonotic organism causing granulomas, abscesses, skin lesions, and bronchopneumonia in humans.
What does Actinomyces cause?
Actinomycosis is a rare, infectious disease in which bacteria spread from one part of the body to another through body tissues. Over time, it can result in linked abscesses, pain, and inflammation. It can affect the skin or deeper areas within the body and sometimes the blood.
What is Cervicofacial actinomycosis?
Cervicofacial actinomycosis is a chronic disease characterized by abscess formation, draining sinus tracts, fistulae, and tissue fibrosis.
How is Actinomyces transmitted?
For example, actinomycosis commonly occurs after dental procedures, trauma, surgery, or aspiration 10. Actinomyces spp. is also presumed to be transmitted via direct contact between individuals as part of the normal oral flora 7.
What causes actinomycosis?
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.
How is actinomycosis diagnosed?
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.
What causes anthrax in cattle?
Anthrax is an infectious (can be spread) disease caused by spore-forming bacteria (Bacillus anthracis). It occurs naturally in animals in the southern and southwestern parts of Texas.
What are the symptoms of actinomycosis?
Symptoms
- Draining sores in the skin, especially on the chest wall from lung infection with actinomyces.
- Fever.
- Mild or no pain.
- Swelling or a hard, red to reddish-purple lump on the face or upper neck.
- Weight loss.
What antibiotics are used for Actinomyces?
CLINICAL

|---|---|---|
| Course: | Indolent | Subacute to Indolent |
| Rx: | Penicillin G, ampicillin/amoxicillin, antipseudomonal PCNs, most cephalosporins, macrolides, tetracycline, imipenem, clindamycin | TMP/SMX, imipenem, amikacin, linezolid |
What is actinomycosis and what causes it?
ACTINOMYCOSIS• Actinomycosis is an infectious bacterial disease caused by Actinomyces species such as Actinomyces israelii or A. gerencseriae. ACTINOMYCES IS A NORMAL FLORA • Actinomyces species that cause human disease are not found in nature but are normal flora of the oropharynx, GI tract, and female genital tract.
How long does it take for Actinomyces to grow?
Growth of Actinomyces is slow; it appears within at least 5 days and may take up to 15–20 days. Thus, incubation of at least 10 days is required before conclusion of a negative culture.
What are the characteristics of Actinomyces rods?
Members of the genus Actinomyces are gram-positive, anaerobic, non-acid-fast rods, many of which are filamentous or branching. Branches are <1 mcm in diameter, as opposed to fungal filaments, which are >1 mcm in diameter.
Is penicillin G good for actinomycosis?
Indeed, Actinomyces spp. are usually extremely susceptible to beta-lactams, and especially penicillin G or amoxicillin. As a consequence, penicillin G or amoxicillin are considered drugs of choice for the treatment of actinomycosis.
