    Pyelonephritis in the calf is rarely seen. Unilateral nephrectomy was performed on a 5-month-old male Japanese Black calf affected with pyelonephritis caused by Corynebacterium renale and Escherichia coli. The kidney removed was markedly enlarged and 25 × 20 × 18 cm in size, weighing 2.3kg. Each lobule contained a large amount of creamy pus.
    During an 8 months' postoperative period, the calf was clinically normal and gained weight normally, except that microorganisms were found persistently in the urine.

    From July, 1978 to April, 1979, gangrenous mastitis caused by Clostridium perfringens was observed in six Holstein cows on five dairy farms. It was noticed a few days after parturition by the manifestation of marked congestion, edema, discoloration, heat and hard swelling.
    The bacterial count of C. perfringens ranged from 107 to 108 per gram of mammary tissue and from 102 to 106 per gram of heart, liver, spleen, and kidney tissue.
    Gram-positive, anaerobic bacilli were isolated from the mammary and other tissues and identified as C. perfringens by biological and cultural findings. They belonged to type A as demonstrated by the toxin-antitoxin reaction test and showed weak production of α-toxin in vitro.

  • Field Application of a New Counting Technique of Fasciola Eggs in Bovine Feces
    1. Effects of Improved Filter Net and Technical Skill on Egg Count

    Modifications were made in Taira's method developed in 1978 for the detection of Fasciola eggs. To facilitate filtration, a 60-mesh metal sieve 2.5 cm in diameter was attached to the centrifugation tube used fbr the original method. With it, the rate of egg detection amounted to 64.22% on the average.
    After several trials with the modified technique, a new technician could obtain almost the same results of egg counting as a skilled worker could. Taira's method with these modifications was demonstrated to be highly practicable.

    A Holstein cow 110 days old and a Black Japanese steer about 12 months old died suddenly soon after the onset of disease. Autopsy revealed dark-red foci varying in size and scattered in the brain. Histopathologically, the foci were characterized by cellular infiltration mainly with neutrophils. Finally, the diagnosis of thrombo-embolic purulent meningoencephalitis was made.
