Objective: Purpose of this work was to explore the distribution of LuxS/AI-2 quorum sensing system in Edwardsiella, and analyze expression characteristics and biological function of the key gene luxS accompanying the growth of Edwardsiella.

Methods: The full-length of AI-2/LuxS of Edwardsiella tarda was cloned by PCR based on the sequence on NCBI, then characteristics and conservative structure of this protein-coding gene were analyzed using web database and bioinformatics tools. The anti-rabbits serum was prepared after this protein was purified through prokaryotic expression.

Objective: Nyctereutes procyonoides immunoglobulin G (IgG) gene is partially cloned.

Material And Methods: In order to obtain a certain length (966bp) of Nyctereutes procyonoides immunoglobulin G (IgG), two pairs of primers are designed according to the conserved nucleotide sequence of canine (GenBank:AF354265, AF354265, AF354266, AF354267) and mink (GenBank: L07789). Using Bioinformatics technology and Western-blot to analyze antigenicity of Nyctereutes procyonoides IgG-B gene.

Mink's immunoglobulin (Ig) G Fc gene was cloned, the gene was analyzed by phylogenetic analysis, and western blot was done to prove that the detection of distemper and canine parvovirus in dogs and minks can be universal. In order to get the certain length of Fc segment gene, a pair of primers is designed, which according to the Fc segment gene sequences of mink's IgG (L07789) published by GenBank, extracted total RNA from the spleen of minks and amplified it by RT-PCR. The results showed that the Fc segment gene contained 606 bp.
