SALMONOLLESIS
1 NUMBER SALMOtySON

Salmonellosis (Paratyphus)

Salmonellosis has one of the highest mortality rates of any infectious bacterial disease of pigeons.

Pathogen:
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:

Clinical signs:
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.

Similar conditions:
Paramyxovirus infection, Ornithosis, Coccidiosis, worm infestation, organ form of Trichomoniasis.

Treatment:
Upon appearance of the symptoms described, treatment with chloramphenicol-N should be started immediately. In some cases it is necessary to change the treatment when the results of the bacteriological examination and antibiogram become available.

No free flight for affected pigeons.

Do not provide bath water.

Treat the entire flock rather than individual birds.

Cull severely affected pigeons before beginning the treatment, since it is unlikely that they can be cured.

To check the outcome of the treatment, carry out bacteriological examinations on faecal samples. These should take place at least 14 days after termination of treatment, and then repeated twice at 3-week intervals.
