Duck circovirus infection is an immunosuppressive disease that is characterized by growth retardant and odd deaths. Its infection is usually combined with other pathogens, making the clinical diagnosis more difficult. With the rapid development of molecular biological and immunological technologies, the laboratory diagnostic methods for duck circovirus infection also advance greatly. The paper summarizes the research advances in various laboratory detection methods for duck cireovirus infection including PCR, nested PCR, multiple PCR, fluorescence quantitative PCR, LAMP, nucleic acid probe and ELISA, as well as their ad- vantages and shortages, aiming at providing reference for finding novel detection methods and for the diagnosis and comprehensive prevention and control.

[ Objective] The differences in effective components contents of Lysimachia clethroides Duby were compared using three extraction methods. [ Method] L. clethroides was extracted by three methods, including water extraction, water extraction-alcohol precipitation and 75% ethanol extraction, to determine the effec- tive components of extracts, and contents of calcium, phosphorus and Vc were calculated. [ Result] L. clezhreides contained calcium salt, chlorine, VB1, VB2, Vc and phosphate, but did not contain citrate, sulfate, carbonate or bicarbonate, acetate, lactate, VA , VD and Vs ; the contents of calcium and phosphorus in water extract were 150 and 3.34 mg/g, respectively, greatly exceeding their contents in water extraction-alcohol precipitation and ethanol extraction, while the difference in Vc content was not significant. [ CondusionJ The paper provides a reference for practical application of L. clethroides as an additive.

[Objective] The paper was to explore the combined inhibitory effect of rhizoma coptidis-folium isatidis and rhizoma coptidis-flos poprli against Escherichia coli O2.[Method] Contrast test of single and associated bacteriostasis against known serotype E. coli O2 was conducted using microcheckerboard method.[Result] The MIC of rhizoma coptidis, folium isatidis and flos poprli were 1/8 extracting liquid, 1/8 extracting liquid and 1/2 extracting liquid, respectively. When combined with folium isatidis or flos poprli, the MIC of rhizoma coptidis was 1/8 extracting liq-uid or 1/16 extracting liquid compared with single use. When combined with rhizoma coptidis, the MIC of folium isatidis and flos poprli were 1/8 extracting liquid and 1/16 extracting liquid.[Conclusion] When rhizoma coptidis was combined with folium isatidis or flos poprli, the FIC values were 2 and 0.625, performing independent action and additive effect, respectively.

Honeysuckle, the dry flower bud or with open flower of Lonicerajaponica in caprifoliaceae, has been touted as a cure-all for heat-clearing and detoxifying effect. Honeysuckle contains abundant components such as volatile oil, flavonoids and organic acids, playing the role of antibiosis, antivirus, antiphlogosis, immunopotenfiation and antioxidation. The active ingredients and pharmacological action of honeysuckle are reviewed in the paper, so as to lay the foundation for further application of honeysuckle in veterinary clinic.
