Members of the genus Bacteroides are important components of the normal microbiota of gastrointestinal tract; however, as opportunistic pathogens are also associated with severe or even life-threatening infections with significant mortality. Various species within Bacteroides fragilis group are phenotypically very similar; thus, their identifications with traditional-automated biochemical methods are frequently inaccurate. The identification of the newly discovered or reclassified bacteria can be doubtful because of the lack of biochemical profile in the database of these tests. The aim of this study was to determine the accuracy of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) method by testing of 400 Hungarian Bacteroides clinical isolates. Inaccurate identification results with MALDI-TOF MS were confirmed by 16S rRNA gene sequencing and findings were compared with traditional-automated biochemical test rapid ID 32A method as well.

Objective: Heavy metal pollution is one of the more recent problems of environmental degradation caused by rapid industrialization and human activity. The objective of this study was to isolate, screen, and characterize heavy metal-resistant bacteria from solid waste disposal sites.
Methods: In this study, a total of 18 soil samples were randomly selected from mechanical sites, metal workshops, and agricultural land that received wastewater irrigation.

Background: Difficult-to-treat rheumatoid arthritis (D2T RA) refers to a subset of patients who fail to achieve adequate disease control after the use of two or more biological or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) with different mechanisms of action, while maintaining active inflammatory disease. This presents a therapeutic challenge and highlights the need to explore contributing factors such as the potential role of the gut microbiota. Therefore, the aim of this study was to analyze the gut microbiota and inflammation in patients with D2T RA in comparison to patients with easy-to-treat RA (E2T RA).

Introduction: For years, the placenta was believed to be sterile, but recent studies reveal it hosts a unique microbiome. Despite these findings, significant questions remain about the origins of the placental microbiome and its effects on pregnancy and fetal health. Some studies suggest it may originate from the vaginal tract, while others indicate that oral bacteria can enter the maternal bloodstream and seed the placenta.

Comparing the diversity of gut microbiota between and within social insect colonies can illustrate interactions between bacterial community composition and host behaviour. In many eusocial insect species, different workers exhibit different task behaviours. Evidence of compositional differences between core microbiota in different worker types could suggest a microbial association with the division of labour among workers.

Background: Gestational diabetes mellitus (GDM), a severe pregnancy disorder, is a temporary form of diabetes that occurs during gestation. Astragaloside IV (AS IV), a natural and effective composition of , shows pharmacological effects against diabetes. On the contrary, the effects of AS IV on GDM development are still not clear.
