pullorum disease

(pə-lôr′əm)
n.
A contagious, often fatal diarrheal disease of young poultry, caused by salmonella bacteria and usually transmitted by infected hens through their eggs.

pullorum disease

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 and bullfinches. Transmission to mammals is a case report rarity and 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 may hatch and produce infected progeny.

pullorum disease

a disease of birds caused by infection with Salmonella pullorum and characterized by moribund and dead birds at hatching time, by dyspnea and diarrhea in older birds and a reduction in egg yield, and reduction in fertility of the eggs in adults. The disease has been largely eradicated.
