**7.1 Economic importance**

Along with the studies that they present acute infection in hot climates, they can infect almost all types of climates and target both poultry and turkey. They have very much economic importance as they decrease the feed conversion ratio, weight gain, egg production, and septicemia. They target the bones resulting in lameness and osteomalacia. Their pathological lesion may lead to the condemnation of the carcass [24, 25]. There is a study correlating the green discoloration of the liver with the staphylococcal infections and it is concluded it these studies that there is a high correlation between the green discoloration of the liver and the staphylococcal infections, and they termed that condition as the "green-liver osteomyelitis complex" [26, 27] of the turkeys. It should have to be remembered that this pathogen is not the only etiological agent for that correlation, other isolates within these studies were Escherichia coli and many others [26–28].
