Streptomyces species has been commonly reported as a cause of mycetoma. Invasive streptomyces infections are rare. We report a case of late onset neonatal septicemia caused by Streptomyces annulatus in a home delivered baby, which was identified based on morphology and biochemical characteristics. Invasive streptomyces infections may be more common than these isolated case reports.

In Streptomyces lividans, the tight temporal regulation of the transient expression of the sblA gene was shown to involve an operator-like sequence located on the sblA transcript. This operator-like structure constitutes a stem-loop structure containing a Shine/Dalgarno-like sequence. Its destruction, by site directed mutagenesis, led to an enhancement of sblA expression. This structure thus pl...

actinomycetes were isolated from marine sediment samples collected from the east coast of chennai, tamil nadu, india. well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant methicillin- resistant staphylococcus aureus (mrsa) and vancomycin resistant enterococci (vre). the potential isolate vitbrk2 was mass cultured for...

We sequenced and annotated the complete 7,170,504-bp genome of a novel secondary metabolite-producingStreptomycesstrain,Streptomyces albusSM254, isolated from copper-rich subsurface fluids at ~220-m depth within the Soudan Iron Mine (Soudan, MN, USA).

Expression of genes belonging to the pho regulon in Streptomyces coelicolor is positively regulated (as shown by comparing the wild-type and a DeltaphoP mutant) by binding of the response regulator PhoP to 11-nt direct repeats (DRus). These sequences have been found in over 100 genes of Streptomyces coelicolor; 20 of them were cloned and the binding of PhoP(DBD) to most of their promoters has b...

The draft genome sequences of the three pathogens of potato common scab, Streptomyces scabiei S58, Streptomyces turgidiscabies T45, and Streptomyces acidiscabies a10, isolated in Japan, are presented here. The genome size of each strain is >10 Mb, and the three pathogenic strains share genes located in a pathogenicity island previously described in other pathogenic Streptomyces species.

Streptomyces sp. US 24 and Streptomyces sp. TN 58, two strains producing interesting bioactive molecules, were successfully transformed using E. coli ET12567 (pUZ8002), as a conjugal donor, carrying the integrative plasmid pSET152. For the Streptomyces sp. US 24 strain, two copies of this plasmid were tandemly integrated in the chromosome, whereas for Streptomyces sp. TN 58, the integration was...

It has recently been proposed by Wellington et al. that the genus Kitasatosporia Omura, Takahashi, Iwai and Tanaka (9) is a synonym of the genus Streptomyces, and four validly published species, Kitasatosporia setae (9), Kitasatosporia griseola (12), Kitasatosporia phosalacinea (12) and Kitasatosporia mediocidica (3), have been transferred to the genus Streptomyces as new combinations, Streptom...

the streptomycetes are gram positive bacteria with a filamentous form that present in a wide variety of soil including composts, water and plants. the most characteristic of streptomycetes is the ability to produce secondary metabolites such as antibiotics. they produce over two-thirds of the clinically useful antibiotics of natural origin (e.g., neomycin and chloramphenicol. another characteri...

produced by mutants of Streptomyces peucetius^ , the daunorubicin2) producing microorganism, led to the discovery of doxorubicin (adriamycin)3) and other new anthracyclines4~8). By further mutagenic treatment of Streptomyces peucetius var. aureus, sl mutant of Streptomyces peucetius producing 4Odemethyl1 1 deoxydoxorubicin and analogues7), we have recently isolated other new mutant strains.
