The binding rules and regulations for testing and acceptance under the heading of \"Methods for Testing Chemical Disinfectants for Veterinary Medicine\" (team of authors, 1987) have resulted from years of experimental research in the field of disinfectant development. They include a model for bacteriological laboratory testing which is described in this paper, with complementary reference being made to experimental planning and appraisal of disinfection success. An account is given of preparatory testing, using agar diffusion and serial dilution tests, and of main testing, using suspension and microorganism carrier tests. The RF% microorganism reduction rate is introduced for appraisal of disinfection success. With differentiated initial germ counts, the comparability of experimental results provided by RF% has proved to be superior to that obtainable from conventional calculation.</p>","PeriodicalId":8263,"journal":{"name":"Archiv fur experimentelle Veterinarmedizin","volume":"44 1","pages":"103-16"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13342718","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 endogenous sequences exhibited substantial sequence conservation within the gag and pol genes and LTRs, but were characterized by deletions and substitutions within the env region. The endogenous cat retroviral element ECE2 was isolated by screening a genomic DNA library of cat liver DNA with an env-specific cDNA of RD114 virus. It contained an env region which differed from all RD114-related sequences so far isolated and was homologous to the corresponding region of replication-competent RD114 with regard to their restriction map and partial sequence analysis (p20).
