Salmonellosis has one of the highest mortality rates of any infectious bacterial disease of pigeons.
Salmonella typhimurium var. copenhagen, designated as the "pigeon type" salmonella strain.
Given the right conditions, the bacterium can remain infective in the environment for 1 year or more.
Salmonellae are spread by:
inhalation of dust containing the pathogen
contaminated feed (insects, mice, rats)
dirty feed troughs and water bowls
transmission from the hen to the egg
feeding the nestlings with infected crop milk and billing
chronic carriers: pigeons that appear healthy after surviving salmonella infection, but shed the pathogen at irregular intervals and thus pose a risk to the current flock and their progeny.
Acute form (mainly affects young pigeons):
Enteritis with pulpy, mucoid, greenish droppings; once organs (liver, kidneys, spleen) have become infected, there is growth retardation, emaciation and (in isolated cases) death. Embryos infected with salmonellae frequently die in ovo or during the first few days of life.
Chronic form (mainly affects adult pigeons):
Inflammation causes a thickening of the joints, especially the elbow joint, wing or leg lameness, disorders of balance and torsion of the neck. Recognition of the disease: Bacteriological examination of faecal and/or organ samples. An antibiogram is performed to determine which medication is suitable for treatment purposes.
Other signs of Paratyphoid:
We can spot this disease on the moulting season ...the dropping feathers is accompanied with blood on the root end
Loss of condition and weight.
Green slimy droppings.
Swelling of the leg and wing joints.
Limping -pigeons find hard to move on their legs often falling down on their beak
Wings are crawled to the floor because of the swelling joints
