Description
Technical field
The invention belongs to poultry escherichia coli and Salmonella infection treatment technology field, particularly relate to a kind of poultry compound medicine containing Radix Paeoniae Rubra and florfenicol.
Background technology
Fowl salmonellosis (Aviansalmonellosis) is the general name of the poultry disease caused by one or more Salmonellas in Salmonella.Difference according to pathogen antigen structure can be divided into 3 classes: Pullorum Disease, avian typhoid and avian paratyphoid.Wherein Pullorum Disease and avian typhoid Salmonella have host specificity, mainly cause chicken and turkey morbidity; Avian paratyphoid Salmonella then can extensively infect many animals and people, is one of main source of mankind's Salmonella infection and alimentary toxicosis by poultry that it pollutes and products thereof.Fowl salmonellosis often forms quite complicated propagation circulation.Sick fowl and the fowl that carries disease germs are the main sources of infection, by digestive tract, respiratory tract or eye conjunctiva horizontal transmission, poult can be infected after ovum vertical transmission, cause major part dead, poultry carries disease germs for a long time, then the ovum that carries disease germs of output, if hatch in this, as hatching egg, that then can go round and begin again is handed down from age to age, and causes fowl salmonellosis to be difficult to purification in chicken group, causes serious economic loss.Because Salmonella pollutes face greatly in chicken group, and easily produce drug resistance, immune effect of vaccine is in the market all undesirable.Therefore, breeder flock quarantine, medicine control, environment disinfected purifies, strengthen feeding and management and health and epidemic prevention is still control and prevents Salmonella from entering the essential measure of food chain.Chickling drinks 0.01% potassium permanganate solution after going out shell or other drug carries out chemoprophylaxis in 1 ~ 2 day.This bacterium produces drug resistance to common drug, forces in production to have to carry out various medicine and be used alternatingly, in the hope of better controlling fastbacteria.This bacterium produces stronger drug resistance to aminoglycoside medicaments at present, and aminoglycoside inactive enzyme modifies the necessary group of some protection antibacterial activity in these antibacterials molecules, and itself and the ribosomal affinity of target site are greatly reduced.These inactive enzymes comprise aminoglycoside acyltransferase (AAC), aminoglycoside adenylyl transferase (AAD), aminoglycoside phosphotransferase (APH), gland nucleotidyltransferase (ANT) etc.In the fastbacteria of many aminoglycosides, find the inactive enzyme of different qualities at present.
Escherichia coli are common conditioned pathogens, also be the normal a kind of disease sent out, it can formerly have been carried out the coffin upon burial the multiple location severe infections such as chicken acute sepsis, peritonitis, hepatitis, pneumonia, enteritis, also can secondary or mixedly to send out in virosis, causes huge economic loss to aquaculture.The beta-lactam lopps antibiotic such as amoxicillin, ampicillin, ceftiofur, ceftriaxone, amoxicillin/clavulanate, ampicillin/sulbactam are the conventional important drugs 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, and the report about Drug Resistance of E. coli is also more.Research confirms, one of main mechanism of drug resistance produces beta-lactamase, especially extended spectrumβ-lactamase (Extended-Spectrum β-lactamase, ESBLs), this enzyme can be hydrolyzed beta-lactam nucleus more by force and rapidly, makes this kind of antibiotic lose antibacterial activity.ESBLs is the main enzyme type of beta-lactamase, and it not only to cephalo three generations and aztreonam drug resistance, and is crossing drug resistant to aminoglycoside, quinolones and sulfonamides, only to carbapenems, a mould alkene class medicaments insensitive.Many documents reported colibacillary multi-drug resistant with produce ESBLs have substantial connection, both at home and abroad to comparatively pay close attention to.Inventor has carried out the detection of food animal source pathogenic bacterium ESBLs recently, extraction, enzyme press down the researchs such as enzyme protection effect to antibiotic percent hydrolysis and sulbactam, Tazobactam Sodium and Chinese medicine; show the colibacillary drug sensitive test of part ESBLs, its multidrug resistant rate is apparently higher than non-ESBLs bacterial strain.In addition, result also shows to produce ESBLs bacterial strain not only to the serious drug resistance of the third generation cephalosporins such as ceftiofur, and also to multiple antimicrobial drug drug resistance such as fluoroquinolones, aminoglycoside and sulfonamides, fosfomycin etc., in serious multidrug resistant.Inventor is separated to the escherichia coli of resistance to fosfomycin product fosA3 drug resistant gene producing in ESBLs bacterial strain, more strengthen the drug resistance of antibacterial.
Salmonella and colibacillary drug resistance cause raiser's drug cost to increase, and treatment extends the course for the treatment of, and mortality of livestock increases, and brings larger economic loss, and increase poultry drug residue risk to production.Therefore, the medicine that a kind of Salmonella of the drug resistance to no matter whether and escherichia coli can have better therapeutical effect is needed badly in actual production, and can shorten treatment the course for the treatment of, reduce mortality rate, reduce economic loss and reduce drug residue, for raiser creates higher economic benefit, also ensure that the mankind's is healthy and safe.
Summary of the invention
