Summary: Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a simple, fast, and specific method used for bacterial identification, and has also been shown to be useful for identifying certain parasites and arthropod vectors. Fast, simple, and reliable methods for identifying arthropod vectors are crucial for controlling diseases transmitted by these vectors.

Summary: Limited studies have been conducted on antimicrobial resistance in certain species of staphylococci isolated from unpasteurized milk products. This study aimed to investigate the occurrence and antimicrobial resistance of specific staphylococci species in sheep and goat cheeses made from unpasteurized milk. The results showed high resistance to penicillin and erythromycin in all tested species.

Summary: Managing the transmission of antimicrobial resistance requires reliable methods for tracking outbreaks. MALDI-TOF MS was compared with orthogonal approaches for strain typing, including WGS and FTIR, for Acinetobacter baumannii isolates associated with a healthcare-associated infection event. Reliable molecular typing methods can help to trace transmission routes and manage outbreaks.

Summary: The epidemiology of Clostridioides difficile infection (CDI) has changed over the past two decades, with the emergence of clinically relevant C. difficile strains causing severe nosocomial outbreaks. This study reports on an outbreak that occurred in a Long-term Care Unit, which was tracked using a Matrix-Assisted Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) typing approach (T-MALDI). The study also characterized the toxigenic and antimicrobial susceptibility profiles of the C. difficile isolates. The results showed the presence of three different clusters, with one cluster being considered epidemic and susceptible to vancomycin and metronidazole but resistant to moxifloxacin. This is the first reported outbreak associated with a tcdA+/tcdB-/cdt+ genotypic profile. T-MALDI is shown to be a valid and rapid approach for detecting and tracking outbreaks.

Summary: This study used an ensemble of multiple preprocessing methods to extract critical information from complicated mass spectrometry spectral data for identifying microorganisms and predicting antibiotic resistance. The ensemble method outperformed individual methods, achieving the highest accuracy on independent testing datasets. Important peaks related to antibiotic resistance could be detected, providing valuable information for further investigation of the resistance mechanism.

Summary: In this study, the identification of 230 filamentous fungi isolates using MALDI-TOF MS in combination with the Filamentous Fungi Library 3.0 was investigated. The results showed that using the more time-consuming sample preparation methods improved species-level identification rates, and the in-house threshold for species identification was validated for routine use in the laboratory. This suggests that this commercial platform is suitable for routine diagnosis.

Summary: This study investigates the feasibility of using high energy charge remote fragmentations to analyze the N-terminus of proteins, and compares it with low energy collision-induced dissociations. The results show that the amino acid composition significantly affects the dissociation pathways of peptide backbones.

Summary: In this study, Corynebacterium species were isolated and identified from experimental mice in Korean laboratories using various methods. Molecular methods, particularly 16S rRNA and rpoB gene sequence analysis, showed higher accuracy in species identification compared to MALDI-TOF MS and biochemical methods. It is crucial to choose appropriate identification methods to obtain accurate results in diagnosing Corynebacterium in experimental mice.

Summary: This study applied MALDI-TOF MSI and QTOF LC-MS/MS techniques to investigate the spatial distribution changes of low molecular weight compounds in garlic tissue during Laba garlic processing. It was found that some bioactive compounds were transformed or leached out during the processing, while new compounds related to pigments emerged. This study provides a basis for understanding the spatial distributions and changes of compounds in garlic tissue during Laba garlic processing, which may affect the bioactivities of garlic.
