Introduction

A condition of chickens associated with several bacterial infections such as staphylococci, streptococci, Erysipelothrix etc.

Signs

• Fluid-distended abdomen.
• Peripheral vessels congested.

Post-mortem lesions

• Right ventricular failure and ascites.
• Vegetative lesions usually on the right atrioventricular valve.

Diagnosis

Differentiate from broiler ascites syndrome by examination of the interior of the heart. Culture of lesions to confirm the bacterium involved.

Treatment

Medication is only likely to be of value in reducing deterioration in birds that are starting to develop lesions. The choice should depend on sensitivity testing of an isolate.

Prevention

Good hygiene at turn-around. If successive flocks are affected on the same site prophylactic medication ahead of the anticipated problem may be of benefit.
