Emodin methyl ether microemulsion and application thereof

The invention discloses an emodin methyl ether microemulsion and an application thereof. The emodin methyl ether microemulsion is a microemulsion system composed of an organic solvent and a surfactant. Preferably, the formula of the microemulsion system comprises one or more of N, N-dimethylformamide or N, N-dimethylacetamide, ethanol or Tween-20. In-vitro experiments prove that the physcion can be used for killing clinical drug-resistant bacillus cereus, enterococcus faecalis, bacillus gallisepticum, ornithobacterium rhinotracheitis, haemophilus paragallinarum, klebsiella, chlamydia psittaci, mycoplasma gallisepticum and mycoplasma synoviae. Meanwhile, animal experiments prove that the emodin methyl ether microemulsion is suitable for preventing and treating respiratory tract diseases caused by avian rhinotracheitis, haemophilus paragallinarum, klebsiella, chlamydia psittaci and mycoplasma gallisepticum clinically, liver rupture caused by bacillus cereus, enterococcus faecalis and chicken bacilli, and the li
