biocontrol of phytophthora blight and anthracnose in pepper by sequentially selected antagonistic rhizobacteria against phytophthora capsici.we previously developed a sequential screening procedure to select antagonistic bacterial strains against phytophthora capsici in pepper plants. in this study, we used a modified screening procedure to select effective biocontrol strains against p. capsici; we evaluated the effect of selected strains on phytophthora blight and anthracnose occurrence and fruit yield in pepper plants under field and plastic house conditions from 2007 to 2009. we selected four potential biocontrol strains (pseudomo ...201325288942

tsukamurella conjunctivitis: a novel clinical syndrome.in this report, we describe the first three cases of tsukamurella conjunctivitis in the literature. all three patients presented with congestion of one eye with small amounts of serous discharge for 1 to 2 days. all three recovered after 10 days of treatment with polymyxin b-neomycin or chloramphenicol eyedrops. sequencing of the 16s rrna genes of the three isolates recovered from the serous discharge of the three patients showed that they were all tsukamurella species. the phenotypic characteri ...200312843095

isolation and characterization of alkane degrading bacteria from petroleum reservoir waste water in iran (kerman and tehran provenances).petroleum products spill and leakage have become two major environmental challenges in iran. sampling was performed in the petroleum reservoir waste water of tehran and kerman provinces of iran. alkane degrading bacteria were isolated by enrichment in a bushnel-hass medium, with hexadecane as sole source of carbon and energy. the isolated strains were identified by amplification of 16s rdna gene and sequencing. specific primers were used for identification of alkane hydroxylase gene. fifteen alk ...201323790464
tsukamurella tyrosinosolvens intravascular catheter-related bacteremia in a haematology patient: a case report.tsukamurella spp. are a rare but important cause of intravascular catheter-related bacteremia in immunocompromised patients. the organism is an aerobic, gram-positive, weakly acid-fast bacillus that is difficult to differentiate using standard laboratory methods from other aerobic actinomycetales such as nocardia spp., rhododoccus spp., gordonia spp., and the rapid growing mycobacterium spp. we report a case of tsukamurella tyrosinosolvens catheter-related bacteremia in a 51-year-old haematology ...201122195371
tsukamurella tyrosinosolvens--an unusual case report of bacteremic pneumonia after lung transplantation.lung transplant recipients have an increased risk for actinomycetales infection secondary to immunosuppressive regimen.200919909497
clinical characteristics of infections caused by tsukamurella spp. and antimicrobial susceptibilities of the isolates.to investigate the clinical and microbiological characteristics of infections caused by tsukamurella spp., the computerised database of the bacteriology laboratory at national taiwan university hospital (taipei, taiwan) was reviewed retrospectively to identify patients with infections caused by this species during the period january 1997 to december 2008. all of the isolates had been initially misidentified as rhodococcus spp. identification of tsukamurella isolates to species level was carried ...201122014886

isolation and identification of dibutyl phthalate-degrading bacteria from hydrospheres in tokyo.dibutyl phthalate (dbp) is used widely as a plasticizer and is thought to negatively affect various organisms. to isolate and investigate dbp-degrading bacteria from hydrospheres in tokyo, strains were selected on ynb medium containing dbp as the sole carbon source, and candidate strains were identified by zones of clearing around the colonies. degradation of dbp by the strains was subsequently measured with hplc, and bacterial identification was accomplished using 16s rdna sequences. nineteen s ...200919700919
phylogenomic analyses and reclassification of species within the genus tsukamurella: insights to species definition in the post-genomic era.owing to the highly similar phenotypic profiles, protein spectra and 16s rrna gene sequences observed between three pairs of tsukamurella species (tsukamurella pulmonis/tsukamurella spongiae, tsukamurella tyrosinosolvens/tsukamurella carboxy-divorans, and tsukamurella pseudospumae/tsukamurella sunchonensis), we hypothesize that and the six tsukamurella species may have been misclassified and that there may only be three tsukamurella species. in this study, we characterized the type strains of th ...201627493643
