Simons [30] proved the non-existence theorem for stable integral current in acompact Riemannian submanifold isometrically immersed into a unit sphere andvanishing theorem for homology groups. In 1984, Y. L. Xin [47] generalized theLawson-Simon\'s nonexistence theorem for stable integral current and vanishingtheorem for homology groups to the case of compact submanifolds in Euclideanspace, and gave several important applications.

The Cyt b gene of Takifugu fasciatus was proved to have good homology with other 13 species of fishes recorded in GenBank and it has 96.1% homology with Takifugu rubripes, about 75% with Mola mola and Masturus lanceolatus. The tRNA gene has 69 nucleotides and the tRNA has 72 nucleotides. Their sequences are the same as those of Takifugu rubripes.

In this study, the cDNA fragments of G-L intergenic region and polymerase activity module in L gene of two street rabies virus were cloned and sequenced. The nucleotides sequence of these cDNA fragments mentioned above and their deduced amino acid sequence were compared with that of rabies virus strains, rabies-related virus strains and other Rliabdoviridae published previously. The result show that the homology of nucleotide sequence of G-L IGR among MRV, DRV is 83.3%, compared with other rabies-related virus strains, the homology of G-L IGR is between 58.3%-91.7%. the length of G-L IGR of rabies virus is different in Rhabdoviridae.

Strains YL001 and YL002 formed a monophyletic clade with strains of X. nematophilus with sequence homology outweighing 99% and the sequence homology to genus Photorhabdus outweighing 94%. The lag, logarithmic, stationary and contabescence phase of the two bacteria were 0-6, 6-18, 18-66 and 66 h respectively; pH of strains YL001 and YL002 reduced to 5.70 and 5.56 at 12 h, respectively, and then rose gradually to 7.74 and 8.07 respectively when culture finished. Glucose content reduced quickly during 0-18 h, and then kept stable. Amido nitrogen content reached the lowest at 12 h and then rose slowly.
