pullorum disease


Definition A fowl infection by Salmonella pullorum, with a nearly 100% mortality

Epidemiology Domestic or wild poultry–chickens, turkey, guinea fowl, quail, pheasants, as well as sparrows, parrots, canaries, bullfinches. Transmission to mammals is a case report rarity. Transmission is primarily vertical–i.e., through the egg, but can occur by direct or indirect contact with infected birds

Clinical findings Affected birds huddle near a heat source, are anorectic, appear weak, and have whitish faecal pasting around the vent–diarrhoea

DiffDx Fowl typhoid

Prognosis Survivors often become asymptomatic carriers with localised infection of the ovary; eggs laid by such hens hatch as infected progeny

Management The flock is focked…treatment of affected birds merely perpetuates the infection; kill ’em all. 

Synonym Diarrhoea alba
