Article Synopsis
  • The study investigates how mutations in the envZ sensor affect antibiotic resistance and virulence in multidrug-resistant Salmonella enteritidis strains.
  • Five isolates from a patient with severe infections were analyzed through various methods, including whole genome sequencing and virulence tests using an insect model.
  • Results showed that envZ mutations lead to decreased expression of certain outer membrane proteins, enhancing the bacteria's virulence and resistance while also affecting growth and biofilm formation.

Article Synopsis
  • This study explored a clinical isolate (W986) that showed resistance to the antibiotic fosfomycin and characterized the resistance gene and the enzymatic activity of a newly identified enzyme called FosA11.
  • Using advanced genomic sequencing and laboratory techniques, researchers determined that the presence of FosA11 contributes significantly to fosfomycin resistance by showing a 32-fold increase in its minimum inhibitory concentration (MIC).
  • The study highlights the urgent need to understand the molecular mechanisms of fosfomycin resistance as its prevalence increases among Enterobacterales, with FosA11 being a novel potential target for further research.

Background: Mycoplasma pneumoniae (MP) is the most common pathogen of atypical pneumonia and the main cause of community-acquired pneumonia (CAP) in infants and older adults. This study aimed at investigating a method based on the cross-priming amplification (CPA) technique for the rapid detection of MP in clinical specimens collected from patients with CAP.

Methods: The sensitivity and specificity of the EasyNAT MP assay were determined.

Introduction: Antimicrobial resistance has become a major public health threat globally. The prevalence of multidrug-resistant (MDR) bacterial infections increased substantially among inpatients under 18 years of age in recent years. In Zhejiang Province, China, the trends of drug-resistance in non-adult patients from 2014 to 2019 were monitored, aiming to determine the variation patterns and epidemiological features of MDR strains.

Carbapenemase-producing has been a major clinical threat worldwide because therapeutic options are limited. Although New Delhi metallo-β-lactamase (NDM) is an important carbapenemase responsible for carbapenem resistance, it is uncommon in carbapenemase-producing in China. In this study, we described strain HZW25, an NDM-7-producing strain belonging to sequence type 34 (ST34).

The incidence of invasive fungal infections (IFIs) has recently increased, and early and accurate diagnosis of IFIs is important for the rational selection of antifungal drugs with high efficacy. We developed a method for rapid and accurate clinical diagnosis of IFIs and provide a reference for personalized drug treatment.We designed and screened fungal internal transcribed spacer regions with universal primers and designed 8 TaqMan detection probes to establish a multi-channel real-time fluorescent polymerase chain reaction (PCR) melting curve analysis (MCA) method.

Mucormycosis is an angioinvasive fungal infection with a high mortality rate. Patients with hematological malignancies following voriconazole therapy are at high risk from mucormycosis. Here, the present study reports on a 68-year-old man diagnosed with multiple myeloma and secondary myelodysplastic syndrome, who was infected with disseminated mucormycosis with cerebellum involvement confirmed by mycological culture and histopathological examination.

The harvest mouse () is a small rodent species with a wide range of vertical distribution in Taiwan, extending from the sea level to 3100 m altitude. This species has recently suffered from habitat loss in high-altitude areas due to orchard cultivation, which may have resulted in mouse migration from high to low altitude. To investigate whether there is any physiological mechanism involved in altitude acclimation, rat cDNA microarray was used to compare transcriptomic patterns of the skeletal muscle tissues taken from individuals native to the high-altitude environment and those transferred to the low-altitude captive site.

Early and appropriate antimicrobial treatment can effectively reduce the mortality rate caused by bloodstream infections (BSIs) and is critical for favorable patient outcomes. In general, >90% of positive blood cultures will show positive results within 48 h after incubation in the BACTECTM FX system. However, an additional 6-8 h are required to obtain clones of the bacterium and another 10-24 h to obtain antimicrobial susceptibility test (AST) results.

Two new species of rhacophorid tree frog were identified in Taiwan. In both new taxa, derived reproductive characteristics of laying eggs in tree holes and oophagous tadpoles are shared with Kurixalus eiffingeri, but they are divergent from each other in molecular genetics, mating calls, and tadpole and adult morphology. The morphological characteristics and the molecular phylogenetic evidence support the hypothesis that the two new species, Kurixalus berylliniris sp.
