    Fourteen equine cases of cecal constipation colic were found to be complicated with constipation at the ascending colon. Three etiological factors could be considered: the specific morphology of the cecum of the horse, ingestion of fibrous feed, such as hay, and physiological antiperistalsis of the greater colon. Constipation was presumed to have been aggravated gradually by the antiperistalsis.
    Anatomicopathological examination revealed edema or hardening by passive congestion in the intestine, which had been induced by pressure of constipation.

    A total of 235 strains of so-called psychrophilic bacteria were isolated from bottled milk, ice candies, ham and sausage.
    1. Of the 235 strains, 161 (68.6%) were of Pseudomonas (PS), 31 (13.2%) of Micrococcus (MC), 22 (9.3%) of Alcaligenes (AL), 16 (6.8%) of Aeromonas (AR), and 5 (2.1%) of an unidentified genus.
    2. Fat decomposition was positive in most of the strains of AL, AR, and PS, and negative in the MC and unidentified strains. The highest and lowest fat decomposition were seen in the PS and AR strains, respectively.
    3. PS, AL, and AL strains were isolated from U. H. T.-pasteurized milk after incubation at 35, 21, and 5°C, respectively. From milk pasteurized under the holding system, MC strains were isolated at 35°C, MC, PS, and unidentified strains at 21°C, and PS strains at 5°C.
    4. None of the AL strains grew at 35 or 30°C. Some of the PS strains grew, but others did not, at 35°C. The AR strains did not grow well al 35°C. The MC strains showed growth within a wide range from 5 to 35°C, though some of then grew only a little at 5°C.
    5. There was a tendency among the PS strains that pigmentation at King B medium was positive in most of the strains capable of growing at 35°C and negative in the strains which failed to grow al this temperature.

    A mixture of amprolium and ethopabate (Amprol Plus) was evaluated for effect against experimentally induced coccidial infection in chickens, in comparison with amprolium (Amprol).
    The mixture was effective against Eimeria tenella and E. necatrix infections at the same dose levels as amprolium. Against E. acervulina, E. maxima, and E. burnetti infections or a mixed infection with E. tenella, E. acervulina, E. maxima, and E. burnetti, the mixture was more active than amprolium. It was concluded that the mixture was a more effective coccidiostat with a broader anticoccidial spectrum than amprolium.

    A Japanese encephalitis hemagglutination-inhibition (HI) antibody survey was conducted on a total of 1, 763 pigs produced, raised, and shipped in three areas, A, C, and I, or Aikawa, Choyo, and Ichinomiya, during the whole year 1965. There were 737 positive pigs (34.8%). The positive rate was 34.8%, 69.7%, and 44.1 % in areas A, C, and I, respectively.
    A 100 % positive conversion rate was seen in area C over a period from July to September, in area A in August, and in area I in September and October. The rate of cases showing a titer 1: 640 or higher to the whole positive cases was high in area C. The frequency of occurrence of the encephalitis among human inhabitants was also high in this area, indicating a high degree of contamination.
    Flrea C has hot springs which may provide favorable conditions for the occurrence of mosquitoes.
