Oral healthcare is a critical condition for high quality of life. According to statistics, gingivitis is one of major diseases in the world (The Global Burden of Disease Study 2019, 3.5 billion population worldwide). Oral diseases, that initiated by a group of multispecies bacteria with diverse extracellular slime that called biofilms, are modifiable risk factors with the cancer, cardiovascular disease, chronic respiratory disease. Hence, effective management of biofilms is important. Since biofilms are comprised of extracellular matrix that inhibit drug diffusion, the traditional antibiotic treatment requires 500 -5000 times more concentration than planktonic bacterial infection...

(1) Background: The evolution of bacterial resistance to antibiotics is one of the factors that make infectious pathology an extremely dynamic field, also inducing a significant burden on public health systems; therefore, continuous updates on the bacterial resistance to antibiotics and their particular regional patterns is crucial for the adequate approach of various infectious diseases. (2) Methods: We retrospectively analyzed 354 patients with Enterobacterales urinary tract infections (UTIs), determined their antibiotic resistance pattern, thus aiming to correlate them with the outcome and other specific markers of poor prognosis...

Background and Objectives : Management of infectious diseases is a huge burden to every healthcare system worldwide. Antimicrobial resistance, including antibacterial resistance, is an increasing problem worldwide; therefore, more new antibiotics are necessary to be discovered. Meanwhile, "old" antibacterial agents are still administered to fight infectious diseases caused by resistant bacteria. One of these antibacterial agents is vancomycin, which is effective in treating serious systemic infections caused by gram-positive bacteria...

The enormous burden of the COVID-19 pandemic in economic and healthcare terms has cast a shadow on the serious threat of antimicrobial resistance, increasing the inappropriate use of antibiotics and shifting the focus of drug discovery programmes from antibacterial and antifungal fields. Thus, there is a pressing need for new antimicrobials involving innovative modes of action (MoAs) to avoid cross-resistance rise. Thiosemicarbazones (TSCs) stand out due to their easy preparation and polypharmacological application, also in infectious diseases...

BACKGROUND: Helicobacter pylori ( H. pylori ) infection is a worldwide problem with increasing burden on the health sector due to its increasing rate of resistance. The conventional triple therapy (TT) is becoming obsolete with a high failure rate of eradication, necessitating the need for better alternatives or regimens. AIM: To investigate H. pylori eradication rate of TT vs modified bismuth quadruple therapy. METHODS: Ninety-two patients with dyspepsia symptoms and positive 13 C-urea breath test were randomly assigned to two groups...

Background: Extended spectrum β-lactamase (ESBL) and AmpC-producing Gram-negative bacilli contribute significantly to the antimicrobial resistance (AMR) burden worldwide. Temocillin is an intravenous semisynthetic antibiotic that is stable to hydrolysis by ESBLs and AmpC. Temocillin may be a treatment option for serious infections due to these organisms. Methods: Third-generation cephalosporin-resistant Escherichia coli and Klebsiella pneumoniae isolates from the MERINO trial were collected...

Staphylococcus aureus is a versatile human commensal bacteria and pathogen that causes various community and hospital-acquired infections. The S. aureus efflux pump NorA which belongs to the major facilitator superfamily, confers resistance to a range of substrates. Many efflux pump inhibitors (EPIs) have been discovered, but none is clinically approved due to their undesirable toxicities. In this study, we have screened clinically approved drugs for possible NorA EPI-like activity. We identified six drugs that showed the best efflux pump inhibition in vitro , with a fractional inhibitory concentration index of ≤0...

Bacteria-induced acute lung infection (ALI) is a severe burden to human health, which could cause acute respiratory distress syndrome (ARDS) and kill the patient rapidly. Therefore, it is of great significance to develop effective nanomedicine and therapeutic approach to eliminate the invading bacteria in the lung and manage ALI. In this study, we design a layer-by-layer (LbL) liposome-polymer hybrid nanoparticle (HNP) with a pH-triggered drug release profile to deliver antibiotics for the eradication of bacteria to treat ALI...

BACKGROUND: The wide spread of plasmid-mediated colistin resistance by mobile colistin resistance (MCR) in Enterobacteriaceae severely limits the clinical application of colistin as a last-line drug against bacterial infection. The identification of colistin potentiator from natural plants or their compound preparation as antibiotic adjuncts is a new promising strategy to meet this challenge. METHODS: Herein, the synergistic activity, as well as the potential mechanism, of Pingwei pill plus antibiotics against MCR-positive Gram-negative pathogens was examined using checkerboard assay, time-killing curves, combined disk test, western blot assay, and microscope analysis...

Gepotidacin is a novel, first-in-class triazaacenaphthylene antibiotic that inhibits bacterial DNA replication by a distinct mechanism of action with an in vitro spectrum of activity that includes Escherichia coli . Our objectives herein were the following: 1) to identify the pharmacokinetic-pharmacodynamics (PK-PD) index associated with efficacy for gepotidacin against E. coli ; 2) to determine the magnitude of the above-described PK-PD index associated with various bacterial reduction endpoints for E. coli ; and 3) to characterize the relationship between gepotidacin exposure and on-therapy E...

INTRODUCTION: Globally, chronic kidney disease (CKD) is one of the leading causes of mortality. Impaired renal function makes CKD patients vulnerable to drug-related problems (DRPs).

METHODS: A systematic review of the literature was conducted using Medline, EMBASE, PsycINFO, Web of Science (Core Collection), CINAHL plus (EBSCO), Cochrane Library (Wiley), Scopus (ELSEVIER) and PubMed (U...

BACKGROUND: The incidence of spinal epidural abscesses is increasing. What is more, they are associated with high rates of morbidity and mortality. Advances in diagnostic imaging and antibiotic therapies have made earlier diagnosis and nonoperative management feasible in appropriately selected patients. Nonoperative treatment also has the advantage of lower immediate healthcare charges; however, it is unknown whether initial nonoperative care leads to higher healthcare charges long term...

As the global urban populations increase with rapid migration from rural areas, ready-to-eat (RTE) street foods are posing food safety challenges where street foods are prepared with less structured food safety guidelines in small and roadside outlets. The increased presence of extended-spectrum-β-lactamase (ESBL) producing bacteria in street foods is a significant risk for human health because of its epidemiological significance. Escherichia coli and Klebsiella pneumoniae have become important and dangerous foodborne pathogens globally for their relevance to antibiotic resistance...

Background: There is renewed interest in repurposing β-lactam antibiotics for treatment of tuberculosis (TB).

Compounds 36-39 exhibited potent antibacterial activity against hospital-acquired MRSA, with MIC = 8-64 μg/ml...

BACKGROUND: Uncomplicated urinary tract infections are one of the most common bacterial infections in the United States. Clinical practice guidelines from the Infectious Diseases Society of America recommend nitrofurantoin, trimethoprim-sulfamethoxazole, and Fosfomycin as first-line antibiotic treatments and discourage the use of fluoroquinolone antibiotic agents. US Food and Drug Administration released several black box warnings about fluoroquinolones over the past decade owing to antibiotic resistance and a high burden of adverse events...

OBJECTIVE: The goal of administering preoperative systemic prophylactic antibiotics is to have the concentration in the tissues at its optimum level at the start and throughout the surgery. The rationale for the use of antibiotics is not well accepted; possible side effects and development of microbial resistance patterns are potential risks along with the financial burden. Therefore, the present study was conducted with the aim to clinically evaluate the serum and tissue concentration of single-dose prophylactic ceftriaxone during an ongoing laparoscopic cholecystectomy (LC) and to find out risk factors for post operative surgical site infections (SSI)...
