Infections with E. coli
Basically, chickens of all ages are susceptible to E. coli, though septicaemia with E. coli affects mainly chickens from eighth to ten weeks of age and layers. Clinical manifestations can be different: oophoritis and salpingitis, polyserositis, aerosacculitits, pericarditis. Economical losses are significant.
Infections with Clostridium perfringens
Necrotic enteritis affects chickens and turkeys especially in the breeding period. Diarrhoea is occurring with foamy and orange to red faeces.
Respiratory infections of chickens and turkeys
Incidence of different pathogens is typical for respiratory infections. Bacteria such as E. coli, Pasteurella, Staphylococci and Ornithobacterium rhinotracheale (turkeys) are often isolated.
Infectious diseases that are determined by many factors are predominant in intensive livestock farming. Apart from viruses, bacteria such as Staphylococci and Streptococci (septicaemia), E. coli, Clostridia, Pasteurella and Erysipelothrix rhusiopathiae (turkeys) and others can be found.
