Sulbactam is a direct antibacterial activity with high susceptibility to <i>A. baumannii</i> species. Durlobactam, diazabicyclooctane <i>β</i>-lactamase inhibitors possesses a broad-spectrum activity against Ambler class A, C, and D serine <i>β</i>-lactamases. This combination has been studied to overcome resistance to ABC species. Data were obtained from in vitro and preclinical studies as well as phase I, II, and III clinical studies published in English between 200t0 and January 2023. A phase II trial showed similar tolerability and pharmacokinetics parameters of sulbactam-durlobactam in patients with urinary tract infections to placebo. However, no ABC infections were included in the trial. ATTACK, a phase III clinical trial of sulbactam-durlobactam, studied the safety and efficacy of sulbactam-durlobactam in patients with ABC HABP/VABP and showed its noninferiority to colistin. Reported adverse events include anemia, elevated liver enzymes, hyperkalemia, headache, diarrhea, nausea, urticaria, and vascular pain. Sulbactam-durlobactam is a new <i>β</i>-lactamase inhibitors combination active against MDR Gram-negative bacteria including ABC. It is currently approved for the treatment of HABP/VABP caused by susceptible ABC strains.</p>","PeriodicalId":50715,"journal":{"name":"Canadian Journal of Infectious Diseases & Medical Microbiology","volume":"2025 ","pages":"2001136"},"PeriodicalIF":2.6,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11824839/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to comprehensively analyze virulence factors, antibiotic resistance patterns, and biofilm formation in clinical isolates of &lt;i&gt;K. pneumoniae&lt;/i&gt; from Hamadan hospitals.

Initial culturing was performed on blood agar and MacConkey agar, and isolates were identified using biochemical tests. Antimicrobial susceptibility testing followed CLSI, employing the Kirby-Bauer disk diffusion method with 10 antibiotics.
