    In the suburbs of Kobe 105 dairy cows were subjected to fecal examination ten times. Cows from which eggs of Fasciola hepatica had been detected were given an anthelmintic against adult worms seven times. The mean rate of egg detection was 52.2% after the first treatment and 31.2% after the last one, showing a gradual decrease.
    Fasciola infection was presumed to take place mostly by ingestion of metacercariae attached to rice straw. It was concluded that anthelmintic should be used mainly over a period from January to May in the Kobe area, and that each cow should be treated at least three times, or in October, January, and April or May.

    Weaned piglets were administered with the BN strain of Bacillus natto for about 10 days. During this period 103-104 organisms of this strain per gram of feces were detected constantly. They disappeared from the feces 4 and 6 days after the end of administration. The Lactobacillus count increased a little and the Escherichia coli count hardly changed in the feces after the administration of this strain.
    Clinically, diarrhea and soft feces disappeared from the affected piglets after the administration of this strain. Autopsy revealed that B. natto was present in the contents of the upper part of the intestinal canal, but not at all in those of the lower part. Lactobacillus and E. coli were prevalent in the lower part and a very few or absent in the upper part.
    These results suggest that the BN strain of B. natto may hardly multiply in the intestine of the piglet, and that some of the administered organisms of this strain may remain in some form or other in the intestine.

    On a broiler farm Salmonella was detected from 12 of 50 samples collected from the floor of the chicken house and the hand, clothes, and shoes. Since the all-in and all-out method could not be performed on this farm, the following countermeasures were carried out:(1) Sanitary measures, including disinfection, change of clothes and shoes for each house, and isoladon from the chicken dressing plant.(2) Introduction of Salmonella-free chickens, early detection of contamination, and preventive medication.
    As a result, the mean carcase weight per head increased to 1.76 kg from 1.54 kg 6 months after the initiation of the countermeasures.

    A collective outbreak of bovine actinobacillosis was seen in Kushima, Miyazaki, over a period from 1975 to 1976. The disease took the form of suppurative granulomatous inflammation. The affected cattle had been fed slender flexible stems of sweet potatoes abundantly and found as such mostly after the occurrence of suppuration. Therefore, Actinobacillus may have been spread in the barn in a month or two.
