Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of poultry compound medicine containing Radix Helicteris and rifampicin, it can kill antibacterial quickly, overcome large, the residual high and defect that cost is high of weak curative effect that antimicrobial drug treatment causes due to drug resistance problems, consumption, avoid that simple Chinese medicine sterilizing spectrum is narrow, sterilize slow problem.
For solving above technical problem, the present invention by the following technical solutions: a kind of poultry compound medicine containing Radix Helicteris and rifampicin, is made up of the raw material of following weight portion: rifampicin 3-30 part, Radix Helicteris 5-200 part.Described Radix Helicteris belongs to Sterculiaceae Radix Helicteris and belongs to.
Described compound medicine is prepared into powder, tablet, oral liquid or granule.
The preparation method of described compound medicine is: Radix Helicteris was pulverized 60 mesh sieves, then mixes with pulverous antimicrobial drug, is prepared into powder, tablet, oral liquid or granule according to a conventional method.
For the drug resistance problems that current poultry coli-infection exists, inventor utilizes Guangxi Special Traditional Chinese Medicine Radix Helicteris and antimicrobial drug to form compound medicine.Research proves, after adding Radix Helicteris in antimicrobial drug, can reverse bacterial to the drug resistance of antimicrobial drug, thus improve the therapeutic effect of antimicrobial drug.According to a conventional method this compound medicine is made powder, tablet, oral liquid or granule, add in animal and fowl fodder according to the 0.1-7g principal agent/addition of kg feedstuff and feed, can significantly reduce drug cost and drug residue, for raiser creates higher economic benefit, also ensure that food safety simultaneously.
Detailed description of the invention
One, Radix Helicteris is to the drug resistance inversion Effect study of antimicrobial drug
Antimicrobial drug itself has the colibacillary effect for the treatment of, but has stronger drug resistance due to the escherichia coli producing ESBLs drug resistant gene, causes antimicrobial drug not show good therapeutic effect in normal using dosage situation.
In order to verify the drug resistance inversion effect of Radix Helicteris to antimicrobial drug, 96 orifice plates adopt microtest tube doubling dilution, first determine antimicrobial drug to producing the minimal inhibitory concentration of e. coli strains of ESBLs drug resistant gene and Radix Helicteris to the subinhibitory concentration producing ESBLs drug resistant gene e. coli strains, the Radix Helicteris then adding subinhibitory concentration in the medium reuses microtest tube doubling dilution and cultivates the minimal inhibitory concentration measuring antimicrobial drug; Continuous passage method is utilized to carry out Secondary Culture to product ESBLs drug resistant gene e. coli strains in the culture medium being added with same subinhibitory concentration Radix Helicteris and same concentration antimicrobial drug, until the antimicrobial drug minimal inhibitory concentration observed diminishes more than 4 times compared with before going down to posterity, can be judged as that Radix Helicteris has drug resistance inversion effect to antibacterial medical instrument.Result of the test statistics is as shown in table 1:
Table 1 subinhibitory concentration (0.25g/mL) Radix Helicteris goes down to posterity and causes the change (mg/mL) of product ESBLs escherichia coli Western medicine MIC.
As seen from the above table, antimicrobial drug all reduces more than 4 times to the minimal inhibitory concentration of antibiotic-resistance E. coli, can judge that Radix Helicteris has drug resistance inversion effect to product ESBLs drug resistant gene escherichia coli.
