Small ruminants, particularly sheep, are suffering from many respiratory diseases.
Among the causative agents of respiratory diseases, the most important microorganisms
are Mannheimia haemolytica. In the case of a most severe form of infection which is
commonly known as the severe fibrinous pleuropneumonia characterized by fibrin
deposition and merging, intra-alveolar hemorrhage, forceful leukocyte infiltration in
alveoli of the lungs. Being a Gram-negative bacterium, Mannheimia haemolytica is
causing respiratory diseases in animals and pneumonia which is the must dangers
diseases that make a great economic loss. The sheep immune system is responsible for
the detection, capturing and elimination of foreign bodies including bacteria. However,
there are no substantial studies explaining the molecular mechanism of respiratory
diseases and immune system response in sheep lung. Therefore, this study was
conducted to investigate the expression pattern of IL-1β, one of the important genes in
immune system, to understand the molecular mechanism underlying in M. haemolytica
induced infection in sheep lung.
