Stomatitis (SUNPMPV)?
Stomatitis- (SUNPMPV)
- Simple e.g., mild physical - chemical causes
- Ulcerative e.g., satratoxicosis
- Necrotic e.g., necrobacillosis
- Purulent e.g., Actinobacillosis
- Membranous e.g., candidiasis
- Papular e.g., bovine Papular stomatitis
- Vesicular e.g., FMD
Non-infectious agents?
Non-infectious agents
• Physical causes
o Sharp plants, foreign bodies
• Chemical causes
o Fertilizers, acids, alkalis
• Toxicoses
o Stachybotris atra
Infectious agents?
Infectious agents
• Bacteria
o Necrobacillosis, Actinobacillosis
• Viruses
o Bovine
§ FMD, BVD, IBR
o Sheep/goat
§ FMD, sore mouth, blue tongue
• Fungi
o Candidiasis
Clinical signs of stomatitis?
Clinical signs of stomatitis
- Anorexia, depression, fever
- Halitosis (bad breath)
- Disorders of eating- starvation
Diagnosis?
Diagnosis
- Type of stomatitis
- History, typical morphological lesions
- General and other organic symptoms
- Additional laboratory examinations
Foot and mouth disease?
Foot and Mouth disease- Aphtovirus
- Tongue and mucus membranes
- Also affects the udder and hooves
- Both in large and small Ru
Malignant catarrhal fever?
Malignant catarrhal fever- Herpesvirus
- OHV-2
- Lesions in the oral cavity
- Clinical symptoms also occurring in the eyes
BVD and Bluetongue?
Bovine virus diarrhoea (BVD)- Pestivirus
• Treatment based on vaccination
ATTENTION
- Fever, drooling, endemic onset= FMD
- Drooling, CNS= RABIES
- *** DO NOT MANIPULATE THE
MOUTH***
Bluetongue- Orbivirus
- 30 serotypes
- Notifiable disease
Treatment of stomatitis?
Treatment of stomatitis
- Eliminate the cause
- Good quality hay, molasses, bran
- Peroral/ IV fluid
- Local therapy
o 0.1% AgNO3 solution
o 2% borax
o Povidone iodine
o Camomile tea
Actinomycosis and actinobacillosis?
Actinomycosis
- Disease in the bone of the buccal cavity
- Difficult to treat
o Culling
Actinobacillosis
- Caused by sharp object
- At the end of the chronic soft tissue infection= Wooden Tongue
- Difficult to treat
o Culling
Oesophageal obstruction: Choke?
Oesophageal obstruction: Choke
• Obturation (anatomical predilections) leads to spasm resulting in pain, regurgitation, drooling, and bloat
resulting in suffocation, peri oesophagitis and perforation.
Clinical signs of choke?
Clinical signs
- Restlessness- colic like behaviour
- Retching, salivation, regurgitation
- Visible, palpable mass in the jugular groove
- Rapid bloat (within hours)
- Enlargement of left flank
Diagnosis of choke?
Diagnosis
• History, oesophageal tubing, endoscopy
Treatment of choke?
Treatment
• Spasmolytics, analgesics
o Methimazole
• Sedation
o Xylazine
• Removal of the foreign body
o By hand
o Rubber tube
o Via surgery
