Ornithosis occurs in 2 forms:
The acute form can be recognized in young pigeons from: wheezing noises, uni- or bilateral conjunctivitis and muco-aqueous enteritis with diarrhoea.
The chronic form is more often found in adult birds, which, however, show few or no signs of the disease. Pigeons that have recovered are a dangerous source of infection for young pigeons and for humans due to their latent shedding of the pathogen.
Recognition of the disease:
Upon appearance of the symptoms described, treatment with 4 in 1 should be started immediately. Treat the entire flock rather than individual birds.
Cull severely affected pigeons before beginning the treatment as it is unlikely that they can be cured.
