To determine the regulating role of mtlR in transcription of mannitol PTS operon in V.cholerae,and whether it plays a role in the ferment difference of the toxigenic and non-toxigenic strains,the mtlR deletion mutants from the mannitol rapid-ferment strain(non-toxigenic strain) and slow-ferment strain were constructed.Comparisons of the growth in M9 containing 0.2% mannitol as the sole carbon source and pH change in mannitol fermentation media of these wild strains and their mutants,indicated that mtlR is a repressor.Its repression in mtlCBA transcription was further verified with the analyses of quantitative reverse-transcriptional PCR.

Analysis of these mutants revealed that the expression level of the neutral trehalase gene in RNAi mutant (Ma688 strain) was reduced to 42% of which found in wild-type strain and the over-expression mutant (Ma113 strain) showed approximatlely 2-fold higher levels of neutral trehalase mRNA than that found in wild-type control. Then the transformants Ma688 and Ma113 were chosen for closer examination, including trehalose content, storage longevity , thermotol

检测试验菌株的生化特性和对抗生素的敏感性，以及用多种批号的诊断血清进行凝集试验。结果：具有典型的宋内氏志贺菌的生化特性；与对照菌相比，有较高抗生素耐药性，对复方新诺明等多种抗生素耐药。

Additionally, one SsDRV-free strain Ep-1PNA183av that showed hypovirulence was isolated from a mutant of healthy strain Ep-1PNA183, this strain also immunizes the infection of SsDRV, it would be a valuable material to study on the interaction between SsDRV and its host. Surprisingly, we discovered that SsDRV could be transmitted into S. nivalis (in the same genus to S. sclerotiorum) when cultured side by side on PDA plate, this discovery may supply new evidence for the exchange of genetical elements among different species in fungi; the transmission of mycovirus to other species showed that the limitation of vegetative imcompatiblity among different strains might not be key factor to determine the efficiency of biological control with hypovirulence associated mycovirus.

发现了1株不携带SsDRV的核盘菌弱毒力菌株，该菌株对SsDRV具有显著抗性，是研究SsDRV与寄主互作的宝贵材料；还发现SsDRV可以在核盘菌种间传递，深入研究将为生物在种间的遗传物质交换提供了新的证据，也将为广泛利用弱毒相关病毒控制植物病害提供理论依据。
