• Form cysts in the muscles of swine.
• Cause Trichanosis in people who eat under cooked pork and ingest cysts.
o Cysts hatch and larva migrate through the body.
o Larva can cause blindness and severe pain.
• Not common due to confinement practices.
2
Q
MMA (Mastitis Metritis Agalactia):
A
- Causes by a combination of bacteria from the environment.
* Occurs shortly after farrowing.
3
Q
Metritis:
A
uterine infection
4
Q
Mastitis:

5
Q
Agalactia
A
cessation of milk production.
6
Q
Treatment & Prevention of MMA:
A
- Farrow pigs in clean environment!

A
- Viral disease of swine.
- Young pigs most affected, but can occur in all ages of pigs.
- Causes severe diarrhea, vomiting and dehydration .
- Pigs <2 weeks die from dehydration.
- Older pigs have milder disease.
8
Q
Prevention of TGE
A
- Vaccination of sows and gilts prior to farrowing.
- Vaccination of piglets at one week of age to help prevent diarrhea at weaning.
- Before vaccine was available, the intestines of piglets that died from the disease were fed to the pigs to innoculate them with the live virus.
9
Q
Erysipelas or Diamond Skin Disease:
A
- Bacterial disease: Erysipolothrixrhusiopathiae.
- Cause diamond shaped skin lesions
- Chronic arthritis
