Many isolates belonging to the Enterobacteriaceae were collected in 1965 from the inpatients at geographically scattered hospitals in Japan. Among 2,650 Shigella strains examined, 58.4% were found to be drug-resistant; 95.0% of these resistant strains were multiply resistant. Among 434 resistant strains examined, 81% carried R factors that were transferable by cell-to-cell contact. Of 160 isola...

Antibiotic therapy is the gold standard for bacterial infections treatment. However, rapid increase in multidrug-resistant (MDR) and its recent use secondary many COVID-19 patients has considerably weakened treatment efficacy. These shortcomings motivated researchers to develop new antibacterial materials, such as nanoparticle-based platform with ability chances of killing MDR strains prevent t...

background one of the most common nasocomial bacteria is methicillin resistant staphylococcus aureus (mrsa). today, herbal extracts like zataria multiflora from the lamiaceae family are increasingly used. objectives in this study, the antibacterial effect of z. multiflora on 75 strains of was evaluated. materials and methods the strains of staphylococcus aureus were examined for isolation of st...

objective the extensive pollution of natural ecosystems has occurred by organophosphorus pesticides, being used for improvement of crop production in agriculture. biodegradation is interested in application of multifunctional bacteria containing genetical elements which specially degrade organophosphorus compounds. in this paper the detection of two bacteria species, pseudomonas and flavobacter...

The treatment of meningitis is a complex issue when it comes to multi-resistant antibiotic (ATB) bacteria, limiting the drug options that can cross blood-brain barrier and effectively reach subarachnoid space. impact on effectiveness therapeutic arsenal available, due indiscriminate use antibacterial global scale, increases chances failure initial empirical persistence despite culture targeting...

Polymyxins were discovered in the 1940s and used to treat infections caused by gram-negative bacteria. These molecules act destroying cell membrane through destabilization of phospholipids lipopolysaccharides (LPS). Due adverse effects, such as nephrotoxicity neurotoxicity, this class had seen limited use. However, with evolution antimicrobial resistance commercial drugs, use polymyxins has res...

background hospital patients who are nasal carriers of methicillin-resistant staphylococcus aureus (mrsa) are a high-risk potential threat to themselves and other hospitalized patients. the high antibiotic resistance of these isolates renders the treatment of related infections difficult. objectives the present study, for the first time investigated the prevalence of mrsa isolates in nasal carr...
