F
Arthritis is the most frequent clinical sign of canine actinomycosis
F
- respiratory distress
A. hordeovulneris and A. viscosus can cause pleuritis, peritonitis and pericarditis
T
-dog + human
Clinical signs and pathological findings of canine actinomycosis and nocardiosis are generalized
F
Actinomyces bovis is the causative agent of wooden tongue, it generally attacks soft tissues.
F
- cattle lumpy jaw
- Swine udder lesions
Wooden tongue is caused by Actinomyces bovis in cattle.
F
ACTINOBACILLOSES OF RUMINANTS. (lignieresii)
Bovine actinomycosis is caused by Actinomyces lignieresi
F
A. Bovis
Abrasions on the mucous membrane of the oral cavity can predispose to actinomycosis
T
In the case of actinomycosis sulphur granules can be found in the lesions.
T
sulphur granules (Gr + filaments)
o Yellowish, pinhead-sized (A. Bovis)
o Whitish, soft, grey (A. Viscosus)
Lumpy jaw is a common clinical sign of bovine actinomycosis
T
Actinomyces bovis is the causative agent of lumpy jaw
T
Rough feed and tooth eruption can predispose to lumpy jaw
T
Actinomyces bovis can cause actinomycosis in swine.
T
Swine udder lesions
Distortion of the mandibula or maxilla are the typical sessions of swine actinomycosis.
F
-cattle lumpy jaw
Canine actinomycosis is caused by Actinomycosis canis.
F
A. Hordeovulner
A. Viscosus
Prolonged antibiotic therapy is needed to the treatment of actinomycosis
T ( penicillin)
Changing teeth is a predisposing factor in actinomycosis
T
Use of attenuated vaccines against actinomycosis is widespread
F
- No vaccine
The pathological lesions of actinomycosis in pigs are seen in the udder
T?
Sulphur granules are seen in the lesions of actinomycosis.
T
Actinomycosis is prevented with wide vaccination.
F
- no vaccine
Hard, stinging feed predisposes cattle to actinomycosis
T
Beware dry, spiky feed
in the case of bovine actinomycosis the lesions are localized in the udder
F
- mandibula or maxilla
Wounds on the udder predispose swine to actinomycosis.
T
Swine: skin of udder, teats are damaged
Actinomycosis is mainly an acute disease
F
In the case of bovine actinomycosis lesions can be seen in the mandible or maxilla
T
- CATTLE LUMPY JAW
Bovine actinomycosis causes changes in the upper and lower jaw.
T
In bovine actinomycosis, the first changes are seen in the udder
F
Actinomyces causes a generalized infection.
F
In the case of actinomycosis in pigs the lesions are seen in the udder.
T
skin of udder, teats are damaged
Dogs are resistant to actinomycosis
F
A. Hordeovulneris : dogs
Sulphur granules are typical lesions of actinomycosis.
T
Actinomyces viscosus can infect the udder of sow
F
- Actinomyces viscosus : HUMAN, DOG
Actinomyces can affect the retropharyngeal lymph nodes
T
In dogs, grass awns can be a predisposing factor for actinomycosis infection
T
dog: barley grass
A. israelii is the causative agent if canine actinomycosis
F
- human
Swine actinomycosis is caused by Actinomycosis bovis.
T
Actinomyces species are epiphytes.
T
Actinomycosis bovis can cause udder infection in horses
F
- swine
Dogs can be infected by Actinomyces bovis.
F
- A. Hordeovulneris
- A. Viscosus
Vaccines in cattle can be efficient for prevention of the actinomycosis disease
F
- no vaccine
Wound infection is the primary route of actinomycosis infection
T
lesions on skin or mucous membrane –> invasion
Actinomycosis is a gram-negative bacterium.
F
- Gr+
Horses are most sensitive to Actinomyces israelii
F
- human
Lumpy jaw is a frequently seen disease in cattle herds with high morbidity.
