    More than 30 calves were experimentally infected withDictyocaulus viviparuswith the following results.
    (1) First-stage larvae appeared in feces in the 3rd and 4th week after infection, showed a peak in the 5th and 6th week, and disappeared in the 9th or 10th week. This phenomen was influenced to some extent by the number of in fective larvae.
    (2) Pneumonic symptoms, such as increased respiratory rate, high body temperature, and coughing, were seen from three to twelve weeks after infection. Eosinophils began to increase four to five weeks after infection. The severity of pustular bronco-pneumonia with an eosinophilic exudate was parallel with the pneumonic symptoms and the number of adult langworms.
    (3) It was infered that the pattern of excretion of first-stage larvae and the clinical symptoms depended to a large extent upon the nutritional condition and the number of infective larvae.

    Determination of oxytetracycline in porcine liver and kidney was compared between the cup and the disk methods with the following results.
    1. When 0.05μg/mlwas used, an inhibitory circle was formed in the cup method, but was not always apparent in the disk method.
    2. At the point of correction inhibitory circles were scattered more widely in the disk method than in the cup method. The standard deviation was 1.9 times in the liver and 1.8 times in the kidney. These results suggested that it might be necessary to restrict the scattering of these circles to a smaller extent in order to apply the disk method to meat inspection.

    A field survey was carried out to examine the diagnostic value of the gel precipitation test (GPT) with crude protease as antigen for the infection of swine withCorynebacterium pyogenes. The crude protease antigen was prepared from a 72-hour-old culture in modified VL medium incubated under anaerobic conditions.
    All pigs bearing abscesses caused byC. pyogeneson the body surface were positive for the slide GPT. Old pigs with no visible lesions were also posi-tive for this test at the rate of 11.2%. The rate of positive reactors to the slide GPT was 2.5% in pigs under 60 days old, 15.1% in pigs more than 70 days old, and 25.0% in breeding sows. The transmission of colostral maternal anti-protease precipitin to baby piglets seemed to be negligible. These findings suggested that the slide GPT with crude protease antigen might be available for an epiozootiological survey on corvnebacterial infection in swime.

    Expectant brccding swine weighing 100-120kg died suddenly. Autopsy revealed that they were suffering from fibrinous pleuropneumonia caused by infection withHaemophilus parahaemolyticus. SPF swine on an infection experiment manifested the same symptomes and postmortem changes as the clinical cases. The isolated organism was shown to be highly susceptible to aminobenzyl penicillin, chloramphenicol, erythromycin, oxytetracycline, tetracycline, furazolidon, and nitrofuarntoin.
