Introduction: Acinetobacter baumannii, a known causative agent of nosocomial infections, is one of the highly antibiotic-resistant gram-negative bacilli. Carbapenem-resistant Acinetobacter isolates are increasingly reported worldwide. Carbapenems such as imipenem and meropenem are efficient antimicrobial agents commonly used for the treatment of infections caused by multi- resistant A. baumanni...
Background & aim: Pseudomonas aeruginosa is a gram-negative bacillus and an opportunistic pathogen that causes high mortality in immunocompromised patients. The main antimicrobial activity of Satureja khuzestanica essence is due to carvacrol phenolic components. Nanomaterials can be a good choice because of low toxicity to fight pathogenic microbes. The aim of this study was to evaluate the e...
ABSTRACT Background and Objectives: The resistance of gram-negative bacteria to antibiotics has become a serious problem, which imposes a significant increase in treatment costs. Klebsiella pneumoniae is an important nosocomial pathogen from the Enterobacteriaceae family. The aim of this study was to investigate the frequency and pattern of antibiotic resistance in K. pneumoniae strains isolat...
Background: Teucrium polium is a medicinal plant used as an herbal plant for antispasmodic and antimicrobial properties. Objective: This study aimed to evaluate the effect of the essential oil of T. polium against fungal, bacterial strains, and Giardia lamblia. Also, chemical analysis of the essential oil of T. polium was analyzed by GC/MS. Methods: Teucrium polium was collected from the De...
background and objective: organisms producing ctx-m β-lactamases are emerging as a source of resistance to oxyiminocefalosporins such as ceftriaxone and ceftazidime. however, the laboratory detection of these strains is not well defined. in this study, phenotypic assay for screening of extended-spectrum β-lactamases producing strains and molecular assay for the identification of ctx-m β-lactama...
Pseudomonas aeruginosa is an important multi-drug resistant (MDR) opportunistic bacterium. 102 strains of Pseudomonas aeruginosa equally isolated from human and cow milk were subjected to Multiplex-PCR for detection of ESBLs and exoenzymes of U, T, S, OprI, and OprL, Integrons class A encoding genes and genotyping by the ERIC-PCR and PFGE methods. The disc diffusion and E-test based on CLSI (Cl...
This study used multilocus sequence typing (MLST) to investigate the prevalence of Helicobacter pylori ( H. ) mixed infections and involving unrelated strains; determined phylogeographic groups recovered from patients in Ningbo, China. A total 156 isolates were obtained a convenience sample 33 with culture-positive infection. MLST was classify 150 clinical 12 methodological control strains (6 6...
