MT4 - Necrobacillosis and panaritium of ruminants (W) Flashcards
Fusobacterium necrophorum subsp. necrophorum causes necrobacillosis
T
- F. necrophorum subsp. necrophorum: more virulent
- F. necrophorum subsp. funduliforme
Fusobacterium necrophorum subsp. necrophorum can help the agent of foot rot in causing
disease
T
diseases:
* necrobacillosis
* calf diphtheria
* liver „abscesses”
* mastitis
* gingivitis, metritis, peritonitis (dog, cat)
* facilitates foot rot (synergistic effect)
Aerosol infection is a common form of transmission of the agent of necrobacillosis
F
- wounds on mucous membranes (oral cavity, genitals)
- wounds on the skin
- navel infection
- rumen parakeratosis
Necrobacillosis is mainly seen in young animals
T
lambs, calves, rabbit
Rumen parakeratosis can predispose to necrobacillosis
T
Insufficient disinfection of the navel can predispose to necrobacillosis
T
- wound
- neglected disinfection of navel
- change teeth
Abortion is a frequent clinical sign of necrobacillosis
F
- necrosis (oral cavity)
- fever, oedema, pain
- salivation, smell
- painful chewing, swallowing
Laryngeal erosion serves as place of entry for the agent of calf diphtheria
T
- virus
- cough
- laryngeal erosion
calf diphtheria is caused by Dichelobacter nodosus
F
F. necrophorum
Calf diphtheria is caused by Fusobacterium necrophorum subsp. necrophorum
T
Respiratory diseases can predispose to calf diphtheria
T
Fusobacterium necrophorum subsp. funduliforme is the agent Necrobacillosis in lambs
T
- F. necrophorum subsp. necrophorum: more virulent
- F. necrophorum subsp. funduliforme
Necrobacillosis can occur as a consequence of navel infection in lambs
T
Pulmonary necrosis is a frequent lesion of necrobacillosis of lambs
F
Liver necrosis is a frequent lesion of necrobacillosis of lambs
T
necrosis in the liver in the case of:
- naval infection
- rumen parakeratosis
Fusobacterium funduliforme is the causative agent of Necrobacillosis
F
Fusobacterium necrophorum is the causative agent of Necrobacillosis
Necrosis of the mucous membranes in the oral cavity is a clinical sign of Necrobacillosis
T
- necrosis (oral cavity),
- fever, oedema, pain
- salivation, smell
- painful chewing, swallowing
Focal necrosis in the kidney is a frequent post mortem lesion of Necrobacillosis
F
necrosis:
- oral cavity, lips
- local oedema
Necrobacillosis is prevented with wide vaccination
F
- disinfection of the navel
- prevention of predisposing factors
Wounds can predispose to Necrobacillosis
T
Navel infection can occur in the case of Necrobacillosis
T
Lesions of Necrobacillosis can be seen frequently in the oral cavity
T
Rough, sticky feed can predispose to Necrobacillosis
T
Necrosis in the liver can be a post mortem lesion of Necrobacillosis
T
necrosis in the liver in the case of:
- naval infection
- rumen parakeratosis
Necrobacillosis can only be seen in lamb
F
lambs, calves, rabbits
In the case of Necrobacillosis infection can happen through wounds
T
through wound or neglected disinfection of the navel, change of teeth
In the case of Necrobacillosis, aerogenic infection is common
F
wounds, navel infection, rumen parakeratosis
Lesions of Necrobacillosis are frequently found in or around the oral cavity
T
Fusobacteria are highly resistant, they remain viable in the environment for several weeks
F
Wounds and abrasions can predispose to Necrobacillosis.
T
Incorrect disinfection of the naval area can lead to Necrobacillosis
T
Wounds on the oral mucosa can predispose animals to Necrobacillosis.
T
The clinical signs of Necrobacillosis can frequently be seen in young animals
T
lambs, calves, rabbits
Necrobacillosis is a generalized disease with high fever and depression
F
- fever, oedema, pain
- salvation, smell
- necrosis (oral cavity)
- painful schewing, swallowing
