The Hawaiian strain of Myc. lepraemurium suspension in M/20 Sorensen buffer (pH 6.9) with and without 0.5% glucose or pyruvate was kept under aerobic or anaerobic condition which was made by adding paraffin oil. The materials for testing infectivity were taken from each tube stored under definite conditions at appropriate times. The materials were subcutaneously inoculated into several mice for each condition, and mice tested were killed about five months after inoculation.The results obtained here demonstrated that the infectious activity of Myc. lepraemurium was kept for more than 10 days if the bacillary suspension was stored under anaerobic condition, on the contrary, if the suspension was kept under aerobic condition, the infectious activity of the bacilli was lost within 7 days' incubation. The similar findings were observed in the cases of media containing glucose or pyruvate. However, when the medium contained glucose, the infectious activity of the bacillus was lost for a short time even if kept under anaerobic condition. On the other hand, if the medium contained pyruvate, the infectious activity of the bacillus was maintained for more than 20 days after incubation at 37°C either under aerobic and anaerobic condition.","PeriodicalId":14812,"journal":{"name":"Japanese journal of bacteriology","volume":"67 1","pages":"209-212"},"PeriodicalIF":0.0,"publicationDate":"1962-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89086418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antilethal effect of the passive immunization was recognized only against an intravenous challenge with a small dose (5×10-7 mg) of bacteria.When challenge infection was carried out through the subcutaneous (10-4 mg bacteria) or per oral (2-4 mg) routes, no inhibition of bacterial multiplication was noted at all either inregional lymph nodes or in liver and spleen of the immunized mice.The hitherto obtained deta concerning the effect of killed vaccines in experimental typhoid of mice, which was shown to be antilethal only when immunized mice were challenged intraperitoneally, have been discussed with the above-mentioned results.Since the marked clearance phenomenon by antibodies could be observed only in the peritoneal cavity, it seemed reasonable to assume that an antilethal effect was obtained when the clearance was so extensive that very few bacteria could escape from loco to organs. On the contrary, after challenge through various routes other than peritoneal cavity, bacteria, not receiving marked “clearance” effects at loco, easily multiplied in organs of the immunized mice.","PeriodicalId":14812,"journal":{"name":"Japanese journal of bacteriology","volume":"140 1","pages":"797-801"},"PeriodicalIF":0.0,"publicationDate":"1962-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86614616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
