Treatment of inflammatory diseases of the upper digestive tract, associated with Helicobacter pylori has recently greatly complicated by the presence of significant number of resistant strains of this microorganism to traditionally used drugs for eradication therapy. Average resistance to metronidazole and clarithromycin in Russia is about 30 and 25% respectively. The article presents the experience of treating patients with metronidazole resistant strains of H. pylori with using triple therapy, which included a drug used nitrofurans--nifuroxazide in suspension, proton pump inhibitors and clarithromycin.

Killer yeasts, such as the K1 killer strain of S. Cerevisiae, express a secreted anti-competitive toxin whose production and propagation require the presence of two vertically-transmitted dsRNA viruses. In sensitive cells lacking killer virus infection, toxin binding to the cell wall results in ion pore formation, disruption of osmotic homeostasis, and cell death.

The biosynthesis of silver nanoparticles (AgNPs) using cyanobacteria has gained significant attention due to its cost-effective and eco-friendly advantages in green synthesis. Additionally, biogenic AgNPs show great potential for biological applications, particularly in combating infections caused by drug-resistant bacteria and fungi. This study synthesized using the cyanobacterium Oscillatoria salina (Os-AgNPs).

(Z)-3-butylamino-4,4,4-trifluoro-1-(2-hydroxyphenyl)but-2-en-1-one (1), a new β-aminoenone, has been investigated in terms of its intra- and intermolecular interactions. Vibrational, electronic and NMR spectroscopies were used for the characterization, while X-ray diffraction methods afforded the determination of the crystal structure. The compound is arranged in the crystal lattice as centre-symmetric H-bonded dimeric aggregates (C2/c monoclinic space group).

Objectives: Neonatal sepsis is one of the causes of neonatal mortality and bacterial resistance to antibiotics is one of the challenges facing NICU. The aim of this study was to provide a basis for empirical antibiotic selection by comprehensively searching Chinese and non-Chinese databases for studies related to neonatal sepsis pathogenesis conducted in China and synthesizing all the results of the studies conducted in hospitals in China during the period under study METHODS: In this study, we conducted extensive searches of Pubmed, Web of Science, Cochrane, China Biology Medicine disc (SinoMed), China National Knowledge Infrastructure (CNKI) and Wanfang Data. We screened studies published from 2014 to 2023 that were conducted in hospitals in mainland China and involved bacterial blood cultures and susceptibility tests in neonates with neonatal sepsis and extracted the data, which were summarized using Stata 18.

Background: Rising antimicrobial resistance (AMR) is an acute public health emergency impeding the clinical efficacy of surgical interventions. Biliary stent placement is one of the routine surgical procedures that rarely lead to infections that are empirically managed by broad-spectrum β-lactams and fluoroquinolones. Critical priority pathogens, such as carbapenem-resistant Escherichia coli challenge treatment outcomes and infection prevention.
