    In 1968, 100 Suffolk sheep were imported from Australia into the Rumoi district of Hokkaido. One of them died soon after arrival. Autopsy revealed some of its bronchioli harboring white nematodes, which were identified as Dictyocaulus filaria (RUDOLPHI, 1809). Then a number of sheep of this flock were found to cough and run at the nose. Parasitological examination was conducted on this flock by the separation method with centrifugation tubes. It demonstrated the presence of larvae of stage I in 49.3 per cent of the 99 sheep.
    The flock was treated with tetramisole in a dose of 15mg/kg. Two weeks later, larvae were detected from no sheep of the flock. No death occurred to the flock over a period of observation of 5 months, at the end of which no larvae were detected from any sheep.

    Carcase contamination was found to have been reduced when the pig had been washed with water before sacrifice. There was no difference in this effect between well water and chlorinated water. Skinning of the body in hot water was more effective than skinning in the air in reducing the bacterial contamination of the carcase.
    Chlorinated water containing 10ppm of free residual chlorine was effective to kill coli bacilli isolated from the carcase. It had no such bactericidal effect when meat and fat were present with these bacilli.

    The Toxoplasma (Tp) positive rate among pigs kept for beeding was 24.1 per cent on an average in the Asakura district, Fukuoka Prefecture, over a period from 1964 to 1969. The older pigs, the higher was the rate. The rate was about 40 per cent among pigs older than 3 years. It was higher among boars (42.4%) than sows (23.2%). It was found that pigs produced by natural breeding were apt to be infect ed with Tp.
    The positive rate was very low (less than) 2.8% among pigs born from sows having hemagglutinationinhibiting (HA) antibody.
    It seemed that flushing the pig-house every morning and evening might reduce the chance of infection with Tp by cohabitation.
