    As reported in the previous paper, during the course of investigation on mouse leprosy, this author encountered with the fact that subcutaneous nodules in hybrid mice from crosses between C57BL/6 and CF1 developed and reached to their maximum size in a comparatively early period, being followed by a marked regression. This type of mouse leprosy is same as “benign” previously designated by the author.
    In the present experiment, these mice were infected subcutaneously with murine leprosy bacilli and. then superinfected subcutaneously at varying intervals after primary infection. When superinfection was made 2 weeks after primary infection, only a slight difference was noted in the size of leproma palpable at the challenged site between the two groups with and without the primary infection. However, in the cases of superinfection at 8 or 14 weeks, the development of leproma at the site of superinfection was markedly suppressed in the animals with the primary infection. These results therefore support the view that the regression in benign mouse leprosy is due to the developing immunity in those mice.
    A similar tendency was observed in the subcutaneously challenged mice which had been previously infected intraperitoneally, although most of them died of severe visceral lesions caused by primary infection.

    The present paper deals with the property of immunity induced by primary infection in malignant mouse leprosy, In a preliminary experiment of susceptibility of mice to subcutaneous inoculation with murine leprosy bacilli, it was found that hybrid mice between C3H and ddD responded with typical malignant leproma at the site of inoculation. Therefore, these mice were infected subcutaneously with murine leprosy bacilli and then subjected to subcutaneous superinfection with INAH-resistant bacilli 6 weeks later.
    In almost all cases, some delay in leproma onset was observed at the superinfected site, but the once appeared nodules showed gradual increase in size and reached to a large malignant leproma. In the later period, therefore, there was no significant difference in the leproma development of challenge infection between the two groups with and without primary infection. These findings show that this immunity manifests itself only by delayed development of leproma due to superinfection at the early period. However, an interesting observation was that exceptional one case showed a benign type leproma in the superinfected site, whereas malignant leproma was developing at the site of primary infection.
    Similar tendencies were observed in the subcutaneously challenged mice which had been previously infected intraperitoneally. But, as in the experiment of benign mouse leprosy, this experiment was inadequate to investigate sufficiently the immunity elicited by primary infection, because the severe visceral lesions of primary infection caused the hosts die within the observation period.

    As the representative strain capable of showing the benign type leprosy, brown mice of (C57BL/6×CF1) F10 were used for this experiment. These mice were infected subcutaneously or intraperitoneally with murine leprosy bacilli and then superinfected subcutaneously with INAH-resistant bacilli 6 weeks later. To examine the influence of primary infection on the leproma development of superinfection, the drug (INAH) administration was started on the 2nd day of superinfection and continued for 10 weeks. The results were judged by palpation of positive lesions at the challenged site.
    A remarkable suppression of the leproma development of superinfection was observed in treated mice. This observation appears to indicate that the benign type lepromas of primary infection, though inhibited in their progress by INAH, conferred immunity to the superinfection.
    On the other hand, it seemed that immunity did not develop when the mice were treated with INAH before establishment of the characteristic lesions of mouse leprosy.

    In this superinfection experiment, male mice of BALB⁄c strain were used. It is very characteristic in susceptibility to M. lepraemurium, strains Hawaiian-M (HM) and Hawaiian-B (HB), that HM bacilli inoculation of male BALB⁄c mice produced benign type leproma, while HB bacilli inoculation produced large malignant leproma at the subcutaneous infection site.
    These mice were subcutaneously inoculated with HM bacilli (2.8×106) and⁄or with HB bacilli (5.0×106) on their abdomen. Ten weeks after primary infection, these mice were superinfected subcutaneously with HM bacilli (1.0×106) and⁄or with HB bacilli (5.0×106) on their thorax, respectively. Age-matched male mice of BALB⁄c strain were used as controls for the superinfection.
    Some delay was clearly observed in onset and development of leproma at the superinfection site, compared with those of control mice, in almost all the cases. Leproma develpment was weakly suppressed in the mice primarily infected with HB bacilli and superinfected with HB bacilli. In contrast, higher suppression was found in the mice primarily infected with HM bacilli and superinfected with HM bacilli. Particularly, it is of interest that HB bacilli inoculation of the mice primarily infected with HM bacilli produced benign type leproma, whereas HB bacilli inoculation of control mice produced large malignant leproma. Hereupon, in this due combination of primary infection with HM bacilli and superinfection with HB bacilli, conversion of disease type from malignant to benign or intermediate∗ was recognized.
    The results suggest that HM bacilli infection induced higher level of cell-mediated immune reaction to M. lepraemurium than HB bacilli infection in the hosts.

    As stated in the preceding report, agouti mice of (C3H×ddY) Fl were characteristic in their response to subcutaneous inoculation with murine leprosy bacilli, roughly half of them being of malignant type and the rest being of benign type of mouse leprosy. However, when these Fl hybrids had been vaccinated with BCG, challenge lesions took the feature of benign type in all cases. This observation led us further to the study on the influence of primary infection with murine leprosy bacilli, instead of BCG, upon the leproma development of superinfection in these F1 hybrids.
    Mice of (C3H×ddY) F1 were infected subcutaneously with murine leprosy bacilli. Superinfection was made by subcutaneous inoculation 16 weeks later only in the mice of these F1 hybrids, showing malignant leproma at the site of primary infection.
    About half of superinfected mice showed intermediate but rather benign leproma at the challenged site. In the remaining mice, however, the lesions of superinfection were malignant or intermediate but nearer to malignant type. Thereupon, the typical benign leproma could not be observed in all experimental animals.
    It may be stated as a conclusion from the result of this experiment that murine leprosy primary infection can not convert the superinfection from the malignant type to the benign type unlike BCG vaccination.

    The mechanisms of superinfection immunity of R and F factors were studied in Escherichia coli K-12. Zygotic induction of phage γ and F-duction of gal+ were studied with an F'-gal+ in recipients carrying F and R factors and found useful in elucidating the mechanisms of superinfection immunity of these episomes. The results obtained may be summarized as follows:
    1) The superinfection immunity of R and F factors occurs chiefly due to the inhibition of acceptance of these episomes on the cell surface and partly due to the mutual exclusion between homologous episomes inside the recipient bacteria. Thus, the superinfection immunity of these episomes is due to mechanisms fundamentally different from that of the immunity observed in temperate phages, which are caused by repressors.
    2) The superinfection immunity on the cell surface in these episomes can be reasonably accounted for by postulating specific receptors on the surface of recipient bacteria, to which the mating substances of donor bacteria are bound to form conjugation tubes.

    Synthesis of interferon (IF) was induced in chick embryo fibroblast (CE) cells by inoculations of Sindbis virus (SDV), and Newcastle disease virus (NDV) on SDV after irradiation of UV (UV-NDV or UV-SDV). However, CE cells infected with live NDV failed to produce IF. The IF production by these agents was found to be strongly inhibited by the superinfection of some live viruses. Following results were obtained.
    1. The IF production in CE cells primed with SDV, UV-NDV and UV-SDV was suppressed by 1/8-1/64 fold by superinfection of NDV. Suppression of IF production was also observed in CE cells infected with doubly SDV and UV-NDV.
    2. These inhibition were also observed in CE cells infected with UV-NDV or SDV by the superinfection with polio-virus and HVJ, but were not observed when influenza type A virus was employed as superinfecting virus.
    3. The higher m. o. i. of superinfecting virus, the stronger the inhibition of the IF productions. However, the inhibition was not observed in CE cells inoculated doubly with UV-NDV, UV-SDV.
    4. When superinfecting virus, NDV was introduced within 2 hours after inoculation of UV-NDV, IF synthesis was completely inhibited, however, the addition of NDV at 5 hours after the inoculation of UV-NDV was without effect.
    5. The adsorption of UV-NDV to CE cells was not inhibited by the preinfection of SDV, and the synthesis of SDV was enhanced by the addition of UV-NDV to CE cells.

    Double infection or mixed infection with SM sensitive or SM highly resistant bacilli was evoked in mice and the time course of the growth of the bacilli in the organs was investigated.
    Experiments: 1. Experiment of crossed reinfection with H37Rv and SM 1, 000γ bacilli and treatment with SM and INH. 2. Experiment of single infection evoked with either H37Rv or SM 1, 000γ bacilli (20 weeks) and treatment with SM. 3. Experiment of reinfection evoked with H37Rv and SM 1, 000γ bacilli (20 weeks) and treatment with SM. 4. Experiment of mixed infection evoked with H37Rv and SM 1, 000γ bacilli (20 weeks) and treatment with SM.
    Results: 1. No appreciable change was observed between time course of change of number of bacilli found in the organs of mice infected with SM 1, 000γ bacilli and that with H37Rv except the difference in time of appearance of bacilli in the lungs and that of the manifestation of the effects of SM. 2. In reinfection, SM 1, 000γ bacilli appeared in the organs in the same manner as was observed in case of single infection except the difference in time of appearance in the lungs. 3. In mixed infection, time of appearance of SM 1, 000γ bacilli to the lung was different according to the quantity of injected bacilli. However, time course of change in number of bacilli in the organs was similar to that observed in single infection. 4. In double infection with SM 1, 000γ bacilli, body weight of the animals decreased and then increased except in animals infected with a large quantity of bacilli. In mixed infection, body weight decreased independently on SM treatment in the same manner as was observed in single infection with SM 1, 000γ bacilli. 5. The ratio of the number of SM 1, 000γ bacilli to that of the bacilli found in the organs of mice in this experiment greatly fluctuated. However, it more or less depended on the quantity of bacilli injected and gradually increased after 10 weeks, 6. The heavier the weight of the organ, the larger was the number of bacilli. However, no decisive relation was observed to the extent of lesion in organ. 7. In double or mixed infection, SM 1, 000γ bacilli were not interfered with coexisting H37Rv. They proliferated in the organs in the same manner as was observed in single infection except in case of mixed infection. Then the time course of the fluctuation of body weight was different from those observed in case of SM 1, 000γ bacilli of single infection or mixed infection.
