Background and Objective: Staphylococcus aureus bacteria is a common cause of hospital infections. Resistant strains of this bacterium are a major pathogen in causing disease and death in Iran and the world. Therefore, the aim of this study was to investigate the prevalence of mecA methicillin resistance gene and determine antibiotic resistance patterns in S. aureus strains isolated from clinic...
Background: Acinetobacter baumannii is one of the most important causes of nosocomial infections and has an extraordinary ability to obtain antimicrobial resistance to a wide range of antibiotics. Multidrug-resistant strains and producers of AmpC beta-lactamases of this bacterium cause serious infectious diseases in different parts of the hospital and in hospitalized people, and the treatment o...
Tigecycline is regarded as a last-resort treatment for multidrug-resistant Acinetobacter baumannii. However, tigecycline resistance in A. baumannii has increased worldwide. In this study, we investigated heteroresistance isolates from South Korea. Antibiotic susceptibility testing was performed on 323 nonduplicated isolates. Among 260 and 37 tigecycline-susceptible -intermediate-resistant isola...
Background and Aims: Microbial biofilms are responsible for 65% of human infections and antibiotic resistance. Therefore, finding appropriate ways to prevent infection and biofilm formation is essential. Medicinal plants are one of the suitable candidates to inhibit the antibiotics resistance particularly in biofilm forms. In this study, antimicrobial effects of T.C.P combined extracts (methano...
Bacteriophage infection and antibiotics used individually to reduce biofilm mass often result in the emergence of significant levels of phage and antibiotic resistant cells. In contrast, combination therapy in Escherichia coli biofilms employing T4 phage and tobramycin resulted in greater than 99% and 39% reduction in antibiotic and phage resistant cells, respectively. In P. aeruginosa biofilms...
the aim of this study was to assess the prevalence of esbl-producing e. coli in agricultural fields of gorgan district, golestan province. soil samples were collected from 20 agricultural fields, half of them treated with chemical fertilizers and the rest with bovine manure. two samples, from surface and a depth of 15cm, were taken. after enrichment and culture onto macconkey agar, pink colored...
The emergence of antibiotic-resistant bacteria is a growing public health concern and has serious implications for both human and veterinary medicine. The nature of the global economy encourages the movement of humans, livestock, produce, and wildlife, as well as their potentially antibiotic-resistant bacteria, across international borders. Humans and livestock can be reservoirs for antibiotic-...
Background: Escherichia coli (E.coli) bacteria are member of Enterobacteriaceae which are one of the common causes of urinary tract infections. Beta-lactamase enzymes are important factors for antibiotic resistance of beta-lactam family in gram-negative bacteria. According to increasing rate of urinary tract infections due to antibiotic resistant E. coli, the aim of this study was to study the ...
The present study was aimed to evaluate the antimicrobial resistance and the presence of antibiotic resistance genes in Vibrios spp. isolated from seafood. A total of 72 isolates of Vibrio in 6 species including V. parahaemolyticus, V. vulnificus, V. alginolyticus, V. harveyi, V. mimicus and V. cholerae were examined. The results revealed that all isolates were expressing multiple an...
