Abstract

The invention discloses application of citral in inhibition of growth of multi-drug resistant providencia rettgeri. The citral has better in-vitro killing effects on human-derived providencia rettgeriresisting ampicillin, ampicillin / sulbactam, cefazolin, cefotetan, ceftriaxone, ceftazidime, tobramycin, tazobactam and piperacillin, ciprofloxacin, levofloxacin, amikacin, cotrimoxazole, cefepime, ertapenem, imipenem, aztreonam and gentamicin, can inhibit growth of resistant providencia rettgeri, and has the minimum bactericidal concentration of 0.5 mg / mL and the minimum inhibitory concentrationof 0.25 mg / mL; and the inhibition function of the plant extract citral on the multi-drug resistant providencia rettgeri can relieve or solve the problem of increase of drug resistance of the multi-drug resistant providencia rettgeri and provide a theoretical basis for clinical antibacterial treatment and research and development of novel drugs.

Description

technical field [0001] The invention belongs to the technical field of medicine and food safety, and relates to the application of citral in inhibiting the growth of multidrug-resistant Providencia rettgeri. Background technique [0002] Providencia rettgeri belongs to Enterobacteriaceae, which can cause urinary tract infection and other extraintestinal infections, and cause outbreaks of many nosocomial infections. Infection and food poisoning can be caused by massive multiplication in the process. In addition, there are reports of traveler's diarrhea, eye infection, bacteremia, and urinary tract infection caused by this bacteria at home and abroad. In recent years, the clinical isolation rate of multidrug-resistant Providencia rettgeri has gradually increased. There have been many foreign literature reports that Providencia rettgeri can produce IMP-1 metallo-β-lactamases and various A β-lactamase. Another domestic document reported that the clinically isolated Providenci...
