The suspension of washed leptospira was inoculated into modified Korthof's basal medium containing varied amounts of Tween 80 and cultured at 30 C. Cell numbers were counted by using Petroff-Hausser counting chamber every other day. Optimum Tween 80 concentrations for L. canicola were 0.0125 and 0.025%. Cell counts in the second sub-cultures reached 108 per ml the same as the primary cultures. Generation time of L. canicola in 0.025% Tween 80 medium was about 13 hours. Growth of L. icterohaemorrhagiae was inhibited at concentrations greater than 0.0125 per cent. Cell numbers increased about 4 times at concentration of 0.0000125% Tween 80. L. canicola utilizes Tween 80 as a nutrient while L. icterohaemorrhagiae appears sensitive to it. A difference of more than 1,000 times in maximal growth-supporting concentration between L. canicola and L. icterohaemorrhagiae exists. This difference appears to be caused by difference in surface structure and metabolic requirements.","PeriodicalId":14559,"journal":{"name":"Japanese journal of microbiology","volume":"8 1","pages":"103-10"},"PeriodicalIF":0.0,"publicationDate":"1968-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87751161","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}

In EM-resistant strains, EM is an active inducer, while both EM and OM are the inducers in those strains resistant to both EM and OM. However, the induced populations of both strains acquired high resistance (800 μg/ml or more) to all macrolide antibiotics and to lincomycin. The resistance of induced cells was lost when grown in the absence of inducers. From a strain MS537, in which EM is an inducer, a mutant MS537-1 was obtained on the plate containing OM. In strain MS537-1, OM, in addition to EM, has become an active inducer for macrolide resistance. When MS537 and MS537-1 were cultured on the plate containing LM, mutants MS537-2 and MS537-3 were obtained, respectively. They were found to be highly resistant to all macrolide antibiotics and to lincomycin, and their resistance was not inducible but constitutive. According to transductional analysis, it was found that the loci concerned with induction for macrolide resistance and those governing cross-resistance to macrolide antibiotics were co-transducible, both loci not being separated by transduction. The constitutive resistance to macrolide antibiotics and to lincomycin in strains MS537-2 and MS537-3, was also co-transducible, suggesting that the resistance to macrolide antibiotics and to lincomycin are determined by a gene or by a cluster of genes in the cocci.","PeriodicalId":14559,"journal":{"name":"Japanese journal of microbiology","volume":"17 1","pages":"179-188"},"PeriodicalIF":0.0,"publicationDate":"1967-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75305853","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}
