The result indicated: antibacterial concentration of inner thallus increased progressively with time prolongation when added CCCP with antibacteria, proved that multi-resistance of E.coli in livestock and avian is mediated really by active efflux system; The multi-resistant level have positive correlation with AcrAB transcription and expression level; Quantitive RT-PCR,Western-blotting and fluorescence quantitive PCR can use to detect AcrAB.these results provide theory foundation to detect and study multi-resistance of E.coli in veterinary clinic and have a important scientific significance to develop neotype antibacterials.

Jq Ez6_{0An outbreak of highly pathogenic avian influenza caused by H5N1 virus occurred in Vietnam, Japan and Korea, commencing in December, 2003. By February, 2004, it has been distributed widely in Asia and brought heavy losses. H5N1 are ball-like RNA viruses, birds can shed them via respiratory system, ocular secretions and feces, sometimes transferred to human and cause lethal infection. H5N1 patients have prominent features of reactive hemophagocytic syndrome,bronchiolar inflammation, necrosis of bronchial epithelium and organizing,diffuse alveolar damage with interstitial fibrosis.

Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all birds died within 24 h after inoculation.

Moreover, we we sequenced the entire mitochondrial DNA control region from 17 charadriiform species, and found that the base composition and distribution of the variable nucleotide sites within the control region were similar to other avian species, but a series of short tandem repeated motifs in the 3' end of domain III made A nucleotides and length increased significantly. Phylogenetic analysis showed that these sequences could not well resolve the relationship among genus in Charadriiformes, but within genera maybe has some valuable phylogenetic information.
