Vesicular exanthema
Vesicular exanthema is clinically indistinguishable from foot-and-mouth disease and therefore is of great importance.
Description
Swine vesicular exanthema virus is different from those that cause Foot-and-mouth disease and swine vesicular disease, but produces a disease clinically indistinguishable from these two diseases. Unlike from foot and mouth disease, vesicular exanthema affects pigs only.
Symptoms
All ages
- Low mortality; some deaths can be seen in nursing piglets.
- Salivation.
- Loss of appetite.
- Blisters around mouth, nose, tongue and feet.
- The growing pigs can become weak.
Causes/contributing factors
- Feeding pigs with uncooked swill.
Diagnosis
- It is the same as for suspected FMD and for swine vesicular disease and requires laboratory tests for its identification.
Control/Prevention
- Because it cannot be clinically distinguished from FMD, relevant authorities should be contacted immediately.
