By a method combining filtration and cultivation an unidentified Gram-negative bacillus was isolated from the nasal exudate of fowl experimentally infected with an uncomplicated coryza. Isolation was accomplished by cultivation on sealed blood agar plates after unsuccessful attempts to produce colonies on open plates. Injection of the organism into the palatine cleft of normal birds was regularly followed by an inflammation of the nasal mucosa and a discharge from the nares. A para-influenza bacillus which was also recovered from the nasal tract of affected fowl was innocuous. Certain cultural characters of the bacillus, bearing on its classification, are discussed.
