| a novel lysozyme from xanthomonas oryzae phage varphixo411 active against xanthomonas and stenotrophomonas. | in this study, a bacteriophage of xanthomonas oryzae pv. oryzae designated as varphixo411 was isolated. random sequencing of its genome revealed that it is closely related to another x. oryzae phage, xp10. a cloned fragment carries the lysozyme gene, lys411. the deduced protein, lys411, shares 92% identity with xp10 lysozyme, which contains an extra 46 aa at the n-terminus. lys411 shows over 40% identities to several other phage lysozymes. the his-tagged protein, lys411h, expressed in escherichi ... | 2006 | 16908188 |

| influence of harvest bacterial contamination on autologous peripheral blood progenitor cells post-transplant. | microbiological contamination of manipulated blood products, including hematopoietic progenitors obtained from peripheral blood, is an infrequent but persistent problem in transplant units. the relevance of such contamination in causing patient infection has been reported as insignificant, but the effect on the post-transplant course has not been well documented. we studied the incidence of bacterial contamination in autologous peripheral blood progenitor cell transplants in two of the bench pro ... | 2007 | 17173054 |
| volatiles of bacterial antagonists inhibit mycelial growth of the plant pathogen rhizoctonia solani. | bacterial antagonists are bacteria that negatively affect the growth of other organisms. many antagonists inhibit the growth of fungi by various mechanisms, e.g., secretion of lytic enzymes, siderophores and antibiotics. such inhibition of fungal growth may indirectly support plant growth. here, we demonstrate that small organic volatile compounds (vocs) emitted from bacterial antagonists negatively influence the mycelial growth of the soil-borne phytopathogenic fungus rhizoctonia solani kühn. s ... | 2007 | 17180381 |
