Lamb Dysentery Flashcards
(15 cards)
Dysentery:
Diarrhea with mucus membrane or with blood
Definition
is an acute infectious toxemic disease of newborn lambs and calves.
Etiology
caused by the toxin of Cl. perfringens typeB gram positive rod , spore forming
Characterized by
short course, diarrhea and ulcers in the small intestine
Cl. perfringens type:
- Type A cause:
- Wound infections, Gangrenous Mastitis and food poisoning in humans
Cl. perfringens type:
- Type C cause:
- Struck and Enterotoxemia in calves, lambs, piglets
Cl. perfringens type:
- Type B cause:
- Lamb Dysentery and Enterotoxemia in calves, goats and foals
Cl. perfringens type:
- Type D cause:
- Pulpy Kidney
Cl. perfringens type:
- Type E cause:
- Enterotoxemia in calves and lambs
Transmission and mode:
By ingestion ( except who cause disease in tissue, transmission by contact )
Pathogenesis
The bacteria are present in the soil. They enter the intestine and reach the anaerobic environment, where they begin to release toxins that cause destruction of the cells. This leads to diarrhea, because the cells responsible for absorption are damaged. As a result, the animal develops diarrhea, acidosis, and anemia. If the toxin enters the bloodstream, toxemia occurs, which can lead to shock and death.
Clinical signs
Diarrhea or dysentary, acidosis, toxemia, dehydration, abdominal pain
Diagnosis
- A sample is taken from the lesion, and the toxin is detected using ELISA.
- lesion from intestine - microscopic examination
Treatment
Treatment includes correcting dehydration and acidosis, and administering antibiotics such as penicillin
Prevention and control
- Vaccinate the mother one month before birth to produce antibodies in the colostrum.”
- Vaccinate at one month of age, or on day one if no colostrum was received.
