    It was clarified that the reaction velocity at which resazurin (RZ) in RZ test paper changed to resorufin belonged to the firstorder reaction. When RZ test paper containing l0s S.P.C. per ml of fresh milk was cultured at 37°C, the velocity constant was 0.014. It was presumed from these results that the RZ reaction might have been in progress normally in the RZ test paper. Accordingly, this paper was known to be used for a practical test with success.
    The reaction velocity of RZ in fresh milk contained to the test paper was almost doubled when there was a rise in temperature by ten degrees centigrade. Incubation of RZ test paper at 18°C for 4.5 hours was to give the same result as that of conventional culture at 37°C for an hour theoretically.

    About one thousand calves of the native Japanese breed on pasture were found infected with infections suppurative bronchopnenmonia in the Noto district, ISHIKAWA Prefecture, over a period from 1964 to 1968. Of them, 34 calves (3%) succumbed or were condemned.
    Etiological investigation revealed that they were cases of shipping fever induced by mixed infection with Type III parainfluenza virus, adenovirus, Pseudomonas aeruginosa, Proteus, Alcaligenes faecalis, Escherichia coli, Haemophilus, and Alkalescens dispar.
    After an incubation period of about ten days, an infected calf manifested pyrexia, coughing, nasal discharge, mucous rale, and diarrhea. It took two weeks to more than a month for the calf to recover. Death occurred sometimes. Stress from changes in environment was an inportant factor to induce infection. Transmission was direct or indirect and mild. The infection might become enzootic and hard to control.
