摘要
[Objective] This study aimed to screen Chinese herbal medicines resistant to Chicken Escherichia coli and infectious laryngotracheitis virus. [Methed] Conven- tional punch method, test tube method and plate dilution method were adopted for in vitro susceptibility test of chicken E, coil strains O5 and O8 using 13 kinds of Chi- nese herbal medicines including Sanguisorba officinalis, Coptis chinensis, Anemar- rhena asphodeloides, Strobilanthes cusia, Agastache rugosa, etc.; chicken embryo inoculation experiment was adopted to screen Chinese herbal medicines resistant to chicken infectious laryngotracheitis virus. [Result] Sanguisorba officinalis, Fructus mume, Rheum officinale, Coptis chinensis, Herba Taraxaci, Anemarrhena asphode- Ioides, Scutellaria baicalensis and Rhizoma Fagopyri Cymosi had ideal antibacterial effect against chicken E. coil strain O5; Sanguisorba officinalis, Fructus mume, Rheum officinale, Coptis chinensis, Herba taraxaci and Rhizoma Fagopyri Cymosi had ideal antibacterial effect against chicken E. coil strain 08; other Chinese herbal medicines showed relatively poor or no antibacterial effect. Results of chicken embryo inoculation experiment showed that nine kinds of Chinese herbal medicines showed relatively strong anti-lLTV effect, including Forsythia suspensa, Radix Isatidis, Fofium isatidis, Flos Ionicerae, Radix codonopsis, Radix astragali, Atractylodes, Radix gly- cyrrhizae, and Pericarpium granati. [Conclusion] The study laid the foundation for fur- ther development of Chinese herbal compound preparations to treat chicken cofibacil- Iosis, infectious laryngotracheitis and other bacterial, viral diseases.
[目的]筛选抗鸡大肠杆菌和传染性喉气管炎病毒的中草药。[方法]采用常规中药平皿打孔法、平皿稀释法及试管法,选用地榆、黄连、知母、板蓝根、藿香等12味中草药对鸡O5型大肠杆菌和鸡O8型大肠杆菌进行体外药敏试验;采用鸡胚接种试验,筛选抗鸡传染性喉气管炎病毒的中草药。[结果]对鸡O5型大肠杆菌效果较好的中草药有:地榆、乌梅、大黄、知母、黄芩和金荞麦;对鸡O8型大肠杆菌效果较好的有:地榆、乌梅、大黄、黄连、蒲公英和金荞麦;其他药物对鸡O8型及O5型大肠杆菌效果较差或无抑制作用。鸡胚接种试验结果显示,连翘、板蓝根、大青叶、金银花、党参、黄芪、白术、甘草以及石榴皮9种中草药具有较强的抗鸡传染性喉气管炎病毒作用。[结论]该研究为进一步开发治疗鸡大肠杆菌病、鸡传染性喉气管炎以及其他细菌、病毒病的中草药复方制剂奠定了基础。
