AB - PLEOMORPHIC MICRO-ORGANISM ASSOCIATED WITH ACUTE INFECTIOUS AVIAN LARYNGOTRACHEITIS * ROBERT GRAHA:yr FRANK THORP, JR. AND W. A. JAMES URBAN A, ILL. Studies concerning the cause and nature of avian laryngotracheitis have been conducted at the Illinois Agricultural Experiment Station at intervals during a period of seven years. This disease in fowls is characterized by a mucous, hemorrhagic, croupous or fibrinous exuda­ tive laryngitis and tracheitis. The lesions for the most part are con­ fined to the larynx and the upper part of the trachea, though the pharynx, bronchi and lungs are occasionally involved. The gross lesions of the acute disease at autopsy suggest a primary inflammation of the larynx and trachea, though the lesions in the subacute type arc marked by mild inflammatory changes in the larynx and trachea and clinical manifestations of toxemia. A high mortality may accompany the acute form of the disease, though the subacute infection is mild, with slight clinical signs of illness. However, chronic subacute laryngotracheitis may ultimately prove fatal. BACTERIAL FLORA OF THE LARYNGEAL EXUDATES During the seven year period of the investigation of this disease many potentially pathogenic and semi pathogenic micro-organisms, such as streptococci, staphylococci, micrococci, Ps. aeruqinosa, Pasteurella avicida and
