Pityriasis rosea is an acute, self-limited papulosquamous dermatosis of the trunk and extremities. Many atypical forms of the disease have been reported in the literature [Ahmed et al.: Clin Exp Dermatol 2000;25:624-626; Imamura et al.: Dermatologica 1985;171:474-477]. It is rare to find pityriasis rosea in multiple family members (within a household) at the same time. There have been only 4 re...

Host-specificity tests were conducted involving two provenances of D. tomentosus: one collected from C. imbricata in South Africa (henceforth called the imbricata provenance) and one collected from C. rosea in Mexico (henceforth called the rosea provenance). These provenances were reared on both C. imbricata and the target weed, Cff. On the target weed, the imbricata provenance survived poorly ...

Allelopathy offers potential for weed control through the production and release of allelochemicals from leaves, flowers, seeds, stems and roots.  In this research, allelopathy potentials of ethanolic and aqueous extracts of Vinca rosea L. leaves were evaluated. Three extract concentrations, including 2.5, 5 and 10% (w/v) of both aqueous and ethanolic were prepared from a 10% w/v stock solution...

Temporal changes in a feedlot drainage lagoon with a predominance of the phototrophic purple sulfur bacterium, Thiopedia rosea, were investigated during a 3-year period. The surface protein and bacteriochlorophyll concentrations, which indirectly measure T. rosea abundance, peaked annually during the fall months and coincided with the intensity of pink coloration. Surface bacteriochlorophyll co...

Clonostachys rosea f. catenulata is a promising biocontrol agent against many fungal plant pathogens. To identify mycoparasitism-related genes from C. rosea f. catenulata, a suppression subtractive hybridization (SSH) cDNA library of C. rosea f. catenulata HL-1-1 that parasitizes the sclerotia of S. sclerotiorum was constructed. 502 clones were sequenced randomly, and thereby 472 expressed sequ...

218 Indian Dermatology Online Journal | Volume 8 | Issue 3 | May‐June 2017 Many viruses including HHV6 and HHV7 have been proposed as causative agents for pityriasis rosea, although there is no conclusive evidence. Here, we presented a case of pityriasis rosea coexisting with oral HSV1 infection. Our case is unique because purpuric pityriasis rosea has not been associated with HSV1 previously. ...

OBJECTIVE To examine the proposed association between pityriasis rosea and human herpesvirus 7 (HHV-7). DESIGN A retrospective cross-sectional survey. SETTING University medical center in Switzerland. PATIENTS Thirteen patients with pityriasis rosea and 14 persons with normal skin (control subjects). MAIN OUTCOME MEASURES Detection of HHV-7-specific DNA sequences and antigen (85-kd phos...

BACKGROUND This study was conducted to evaluate the effects of rhizome powder from the herb Rhodiola rosea, a traditional Western Ukraine medicinal adaptogen, on lifespan and age-related physiological functions of the fruit fly Drosophila melanogaster. RESULTS Flies fed food supplemented with 5.0 mg/ml and 10.0 mg/ml of R. rosea rhizome powder had a 14% to 17% higher median lifespan, whereas ...

The objective of this study was to assess antagonism of nematophagous fungi and species producers metabolites and their effectiveness on Haemonchus contortus infective larvae (L3). Assay A assesses the synergistic, additive, or antagonistic effect on the production of spores of fungal isolates of the species Duddingtonia flagrans, Clonostachys rosea, Trichoderma esau, and Arthrobotrys musiformi...

Here, we report the draft genome sequence of Clonostachys rosea (strain YKD0085). The functional annotation of C. rosea provides important information related to its ability to produce secondary metabolites. The genome sequence presented here builds the basis for further genome mining.
