Abstract

The invention relates to a method for screening traditional Chinese medicines influencing the drug resistance of escherichia coil generating ESBLs (extended spectyum beta lactamase). The method comprises the following steps of: determining the minimum inhibitory concentrations of western medicines and traditional Chinese medicines to escherichia coil strains generating ESBLs through adopting a microtest tube double broth dilution method on a 96-well cell culture plate, then adding the traditional Chinese medicines with the sub minimum inhibitory concentrations into a culture medium, and culturing and determining the minimum inhibitory concentrations of the western medicines through using the microtest tube double broth dilution method again; and subculturing in the culture medium added with the traditional Chinese medicines with the same sub minimum inhibitory concentrations and the western medicines with the same concentrations through utilizing a continuous passage method until observing that the sub minimum inhibitory concentrations of the western medicines are reduced by more than 4 times than those before the passage culture, and thus judging that the traditional Chinese medicines have multidrug-resistant reversion functions on the western medicines. The method is not limited by the culture possibility of bacteria which are effected by the traditional Chinese medicines, the bactericidal effect and multidrug-resistant reversion function of the traditional Chinese medicines are not interfered with each other, so that the screening type and scope of the traditional Chinese medicines are broadened; and the method is convenient to operate, and the screening result can be accurately and quickly determined.

Description

A kind of to producing the sex Chinese medicine screening method of ESBLs intestinal bacteria generation resistance
Technical field
The present invention relates to a kind of to producing the sex Chinese medicine screening method of ESBLs intestinal bacteria generation resistance.
Background technology
Intestinal bacteria are common conditioned pathogens, can the former multiple location severe infections such as chicken acute sepsis, peritonitis, hepatitis, pneumonia, enteritis of having carried out the coffin upon burial, but also secondary or mixed in virus disease, cause huge financial loss to aquaculture.amoxycilline Trihydrate bp wherein, the Ampicillin Trihydrate, ceftiofur, ceftriaxone, amoxicillin/clavulanate, the beta-lactam lopps microbiotic such as ampicillin/sulbactam are the important drugs commonly used of this disease of control, along with cultivation scale intensive degree is more and more large, medication is more and more spread unchecked, its Resistant strain is more and more many, more about the Drug Resistance of E. coli report, one of main mechanism that studies confirm that at present resistance is to produce β-lactamase, especially extended spectrumβ-lactamase, hereinafter to be referred as ESBLs, ESBLs can be more by force and is hydrolyzed fast beta-lactam nucleus, make this class microbiotic lose anti-microbial activity.ESBLs is the main enzyme type of β-lactamase, and ESBLs is not only to cephalo three generations and aztreonam resistance, and aminoglycoside, quinolones and sulfamido are the intersection resistance, only to carbapenems, a mould alkene class medicaments insensitive.Present many documents have reported that colibacillary multi-drug resistant and generation ESBLs have substantial connection, comparatively pay close attention to it both at home and abroad.I have carried out the detection, extraction, enzyme of chicken source pathogenic bacterium ESBLs to the researchs such as the enzyme protection effect that presses down of antibiotic percent hydrolysis and Sulbactam, Tazobactam Sodium and Chinese medicine.Colibacillary drug sensitive test shows to part ESBLs, and its multidrug resistant rate is apparently higher than non-ESBLs bacterial strain.Result also shows product ESBLs bacterial strain not only to the serious resistance of the third generation cephalosporins such as ceftiofur in addition, and also to multiple antimicrobial drug resistances such as fluoroquinolones, aminoglycoside and sulfamidos, is serious multidrug resistant.Bacterial drug resistance has become the mankind's huge challenge at present, and " superbacteria " that especially occurred in 2010 makes the mankind more recognize the threat that drug tolerant bacteria produces the mankind.Report in " Information Times " on September 9th, 2010, superbacteria pasts medical help.Zhong Nanshan academician mentions abuse of antibiotics and equals to spin a cocoon around oneself.Also have report to mention Future Ten year, superbacteria can be tackled with antibiotic-free in the whole world, if the impetus of abuse of antibiotics can not be curbed, the mankind will get back to the antibiotic-free epoch, also just mean the epoch for the treatment of with Chinese medicine that come back to.
