Marek's disease (MD or fowl paralysis) is a very common disease of chickens caused by a herpes virus. Marek's disease affects both commercial and backyard poultry and may result in death or severe production loss. The disease causes changes in many of the nerves and may cause tumours in major internal organs. Chickens are the main species affected.

Marek disease can develop in chickens as young as 3 weeks old, whereas lymphoid leukosis typically is seen in chickens >14 weeks old. Reticuloendotheliosis, although rare, can easily be confused with Marek disease, because both diseases can feature enlarged nerves and T-cell lymphomas in visceral organs.

A herpes-type that is very communicable. Marek’s Disease (MD) results in enlarged nerves and in tumour formation in nerve, organ, muscle and epithelial (cells that line the internal and external surfaces of the body) tissue. Clinical signs include paralysis of the legs, wings and neck, weight loss, grey iris or irregular pupil, vision impairment and the skin around feather follicles can be raised and roughened.

The virus can range from non-pathogenic (not causing disease) to highly pathogenic (causing disease and death), and this depends on the strain of Marek’s disease caught.

Marek’s Disease can be found in the environment. The usual symptoms involve the nervous system, eyes, skin and other organ systems. A strong variation of the disease shows tumor growth. Marek’s Disease is mainly seen in young chicks and older chickens.
