Mycoplasma gallisepticum is a pathogenic species within the genus Mycoplasma of the family Mycoplasmataceae.
Mycoplasma gallisepticum (MG) infection, a common disease of poultry, is commonly designated as chronic respiratory disease (CRD) of chickens. Despite success in eliminating the disease in grand parent (GP) stock and turkeys, it persists in broiler breeders and broilers in many areas (1). Mycoplasma gallisepticum is a respiratory disease, affecting the entire respiratory tract, particularly the air sacs, where it is localized. It is mainly characterized by respiratory rales, coughing and nasal discharge. Clinical manifestations are usually slow to develop and the disease has a long course. All the air sacs may be involved, become cloudy in appearance, and filled with mucus. Similar exudates may encircle the heart and heart sac (2). Infected birds remain carriers for life.

Purchase some beautiful Marans from a guy. Within seven days I have to kill my whole flock. Had over 70 chickens. Bleached my pens and let them set empty for 4 weeks. Now my chickens are healthy and do not have disease. Have only had one chicken die in over a year and it got impacted from eating too much whole corn.
disease. I am studying about it, and may try it, then have the birds tested again before culling.
