mice, rats, other birds and/or through contaminated feed. Symptomless adult birds constitute a
human health risk if meat and egg hygiene are not adequate
(12) Colibacillosis
This is the common name for a large variety of diseases, including yolk-sac infection of chicks,
reproductive disorders and peritonitis in layers, and septicaemia (blood poisoning) in growers. They
are all caused by the bacterium Escherichia coli, which is found in the intestines of all warm-blooded
animals
Affected birds can be treated with antibiotics. To prevent further spread of this organism, disinfect
the premises and the pens with a commercial disinfectant, and provide good drainage.
Fungal Diseases
As all domestic poultry, wild birds, other animals and humans can be infected by fungi, take great
care when handling infected birds. Transmission occurs by inhaling fungal spores from sick birds,
contaminated litter or feed.
(13) Aspergillosis
The most common fungal disease in birds is Aspergillus fumigatus, which causes pneumonia or
enteritis in all age groups, especially in the presence of other infections.
Treatment is not recommended. Infected birds should be culled and burned. All mouldy litter
should be removed and burned and the pens should be sprayed with 1% copper sulphate.
(14) Candidiasis or Thrush
Candidiasis is another common fungal disease, which is found in younger age groups of all domestic
poultry. It usually affects the mouth and crop, with sour-smelling crop content. It may also cause
diarrhea. It primarily affects stressed birds. Check for unsanitary conditions, overcrowding and
coccidiosis. Treat with nystatin to provide effective control.
(15) Favus
Favus, or ringworm, also known as white comb, is a fungal disease caused by Microsporum gallinae,
which is of minor importance in all fowl, especially chickens and turkeys. Affected birds have small,
white, chalky deposits on the comb, which can enlarge and coalesce to form a dull white, moldy
