Distribution and Drug Resistance Analysis of Pathogenic Bacteria in Abdominal Cavity Infection
Objective:To analyze the distribution and drug resistance of pathogenic bacteria in peritoneal infection in our hospital,and guide clinical rational drug use.Methods:From September 2018 to July 2024,9902 positive aetiological specimens related to abdominal infection were collected in our hospital to analyze the distribution and drug resistance of pathogenic bacteria.Results:The top five pathogens causing abdominal infection were Escherichia coli(17.00%),Klebsiella pneumoniae(12.02%),Enterococcus faecalis(8.83%),Enterococcus faecium(7.82%),and oligotrophomonas maltophil(7.81%).The resistance rate of Escherichia coli to ceftazidime/avibactam,Klebber pneumoniae to ciprofloxacin,Enterococcus faecalis to tetracycline,quinuptin/Dafoptene,Enterococcus faecium to moxifloxacin,penicillin G,amoxicillin,amoxicillin/clavulanate,ampicillin,and maltophilia to meropenem and imipenem exceeded 80%.Conclusion:In patients with abdominal infection,the most common pathogenic bacteria was Escherichia coli.Early empiric treatment uses antibiotics covering negative bacteria and positive bacteria.Avoid ceftazidime/avibactam for Escherichia coli infections,ciprofloxacin for Klebsiella pneumoniae infections,quinoptin/Dafoptin for Enterococcus faecalis infections,and amoxicillin,penicillin G,moxifloxacin,ampicillin,and amoxicillin/clavulanate for Enterococcus faecium infections.
