    A status quo survey was conducted on parasitic infection of dogs in the Tokyo area for about a year Autopsy was performed on 65 dogs.
    1. Parasites were found in 98.5% of the dogs autopsied. Of them, canine filariae were detected from 89.7%, canine hookworms from 81.5%, canine whipworms from 49.2%, Dipylidium caninum from 49.2%, canine ascarides from 21.5%, and Diphyllobothrium mansoni from 1.5%. The numbers of parasites per capita were 1-51 (14.3 on the average), 1-200 (28.5), 2-181 (27.3), 1-85 (13.5), 1-60 (13.1), and 1, respectively.
    2. Only one species of parasites was harbored by 30.2% of the dogs infected. Two to four species were present in the same individual in 69.8% of these dogs.
    3. The present survey showed essentially the same results asthose conducted in Tokyo during the nineteen thirties to fifties with regard to the species detected and the prevalence observed.

    Typing was made on Salmonella strains detected from broilers produced in Saitama Prefecture and from chicken-processing plants over a period of 1968 to 1971. In 1970, Salmonella typhimurium, S. thompson, and S. infantis were detected at the decreasing order of frequency listed. In 1971, S. sofia was detected most frequently and followed by S. typhimurium and S. thompson in the decreasing order listed
    Resistance to streptomycin (SM) and tetracycline (TC) was observed in 62.1% and 22.3%, respectively. Strains resistant to SM alone were the most numerous and followed by those resistant to SM and TC. Those resistant to TC alone appeared infrequently. There was a rapid increase in rate of detection of strains resistant to SM and TC with the lapse of time. Strains resistant to SM, TC, and kanamycin were detected for the first time in 1971.

    In February, 1970, an infection was found in a certain swinery in Nara Prefecture. Affected animals showed loss of appetite, hacking cough, a high fever, and slight diarrhea. In severe cases, cyanosis appeared at the nose, ear Lobes, and the lower part of the abdomen. Death occurred 4 or 5 days after manifestation of initial signs. Bacteria were isolated from the liver, spleen, and lungs of 2 carcasses just after death or in the moribund. stage They were identified as Salmonella cholera esuis.
    Gross examination revealed edematous swelling of the lungs with dark reddish marginal areas, severe enlargement of the spleen, and cloudy swelling of the liver and kidneys. Under the microscope, there were numerous necrotic foci and activated sinusoidal endothelium in the liver. In the lungs were found atelectasis and thickening of the septal walls caused by a proliferation of histiocytic cells and infiltration of neutrophils. Toxoplasma gondii was negative. This case was presumed to be anacute type of hog paratyphoid.

    Liver cirrhosis occurred collectively to 115 head (14%) of 750 hogs fed a ration prepared by the “N” Company and slaughtered at the abattoir in Omiya, Saitama Prefecture, over a period of January to May, 1969. When a total of 63, 387 hogs, exclusive of the 750 hogs, brought to the abattoir over the same period were examined comparatively, severe liver cirrhosis was found in 64 hogs (0.1%). The difference in rate of detection was significant (P<0.01). When severe cases were observed, the peak of occurrence was seen in March. The etiology of the liver cirrhosis encountered was presumed to consistin feed.
