Avian colibacillosis

While the bacteria Escherichia coli are common inhabitants of the digestive tract and mucous membranes of birds, only some strains virulent characteristics, capable of causing localized and systemic disease, causing large economic losses in the poultry industry (1).
Most of the diseases associated with E. coli are associated with environmental or biological factors that predispose to an attack. For example, environmental agents such as ammonia, CO2 and dust, impair the defense system of cilia and mucus of the upper respiratory tract, bringing a greater susceptibility to infections with E. coli. In the case of Mycoplasma and Bordetella avium, E. coli has a role as a secondary invader in turkeys and chickens (2,3).
The symptoms are varied and depend on the place of infection. Diagnostic methods should differentiate between pathogenic and nonpathogenic serotypes. Bioingentech can detected Escherichia coli using the following techniques, supported by the World Organisation for Animal Health (OIE) (4):
