Bacteriocins (of different origins) have been proposed as promising alternatives to face antimicrobial resistance-associated health problem. Isolates of the genus Staphylococcus are well-known bacteriocin producers, especially coagulase-negative species. Twenty-eight bacteriocin-producing staphylococcal isolates were selected from a previous study for an in-depth characterization. The antimicrobial activities (AA) of the producing isolates were studied by the Spot-on-lawn method and their crude cell-free-supernatants (CFS) and butanol extracts (BT) were evaluated by agar-diffusion assays against six indicator bacteria, including multidrug-resistant and zoonotic isolates (such as Listeria monocytogenes or methicillin-resistant Staphylococcus aureus [MRSA])...

BACKGROUND: There are many reports on gene mutations observed in methicillin-resistant Staphylococcus aureus (MRSA) showing reduced susceptibility to vancomycin. However, there are limited studies on the genetic alterations that contribute to high vancomycin minimum inhibitory concentration (MIC) in methicillin-susceptible S. aureus (MSSA). This study aimed to compare MSSA strains with high vancomycin MIC to those with low MIC and identify specific genetic alterations associated with increased vancomycin MIC...

The emergence of carbapenem-resistant Klebsiella pneumoniae (CRKP) is related to the transmission of carbapenemase genes. Strains carrying more than one carbapenemase with a broadened spectrum of antibiotic resistance have been detected, which is concerning. Although blaKPC -encoding ST11-KL47/KL64 strains are dominant, other clones are emerging. Here, we investigated 137 CRKP from patients' blood samples in Taiwan. Polymerase chain reaction (PCR) was used to identify carbapenemase genes and capsular (KL-)types...

The rapid emergence of infections caused by MDR Acinetobacter baumannii poses a serious threat to global public health. Therefore, it has become important to obtain a deeper understanding of the mechanisms of multidrug resistance and pathogenesis of A. baumannii. However, there are still relatively few genetic engineering tools for A. baumannii. Although A. baumannii possesses Type I-F CRISPR-Cas systems, they have not yet been used for genetic modifications. Here, we developed a single plasmid-mediated native Type I-F CRISPR-Cas system for gene editing and gene regulation in A...

The emergence of pathogens resistant to both tigecycline and carbapenem poses a threat to public health globally. Continuous emergence of novel tet(X) variants accelerates the tigecycline resistance crisis. In this study, we first identified the tigecycline resistance gene tet(X22) and characterized the coexistence of tet(X22) with carbapenem resistance gene blaNDM-1 in Pseudomonas caeni, which was a novel species defined in 2009. The carbapenem- and tigecycline-resistant P. caeni isolate CE14 was obtained from chicken feces in 2022...

BACKGROUND: Neonatal sepsis is commonly treated with vancomycin in the neonatal intensive care unit (NICU). Therapeutic drug monitoring (TDM) of vancomycin is routinely used to personalize dosing to optimize effectiveness and avoid toxicity. This study aimed to define a target range by evaluating associations between vancomycin trough concentrations or area-under-the-concentration-time-curve over 24 hours (AUC24h ) and clinical outcomes in neonates. METHODS: Neonates, who were admitted to the NICU receiving vancomycin intravenously, were included in this retrospective cohort study...

INTRODUCTION: Molnupiravir and nirmatrelvir/ritonavir are antivirals used to prevent progression to severe SARS-CoV-2 infections, which reduce both hospitalization and mortality rates. Nirmatrelvir/ritonavir was authorised in Europe in December 2021, while molnupiravir is not yet licensed in Europe as of February 2022. Molnupiravir may be an alternative to nirmatrelvir/ritonavir, because it displays less frequent drug-drug interactions and contraindications. A caveat connected to molnupiravir derives from the mode of action inducing viral mutations...

Bacteriophage (phage) therapy, exploiting phage which are the natural enemies of bacteria, has been reintroduced to treat multidrug-resistant (MDR) bacterial infections. However, some intrinsic drawbacks of phage are overshadowing its clinical uses, particularly the narrow host spectrum and rapid emergence of resistance upon treatment. The use of phage and antibiotic combination exhibiting synergistic bacterial killing (termed phage-antibiotic synergy or PAS) has therefore been proposed. It is well-reported that the types and doses of phage and antibiotic are critical in achieving PAS...
