Furthermore, determining the levels of quinolones and fluoroquinolones in aqueous matrixes is crucial for safeguarding both human health and the environment. Using sample preparation techniques is essential since these compounds are commonly present in aqueous... -
Research Progress on Drug Intervention to Inhibit Dental Plaque Biofilm Formation by Streptococcus mutans Based on the Concept of Ecological Prevention of Dental Caries
Dental caries is the local destruction of hard tooth tissue caused by acidic byproducts generated by cariogenic bacteria, primarily Streptococcus mutans, which ferment free sugars in the presence of host factors, dietary components, and environmental conditions. A main feature of dental caries is the formation of dental plaque biofilm, which significantly improves the resistance of bacteria to drugs and host immunity. Traditional anti-caries drugs mainly exert anti-biofilm functions indirectly... -

Should I stay or should I go: transmission trade-offs in phages and plasmids
Mobile genetic elements (MGEs), like temperate bacteriophages and conjugative plasmids, are major vectors of virulence and antibiotic resistance in bacterial populations. For reproductive success, MGEs must balance horizontal and vertical transmission. Yet, the cost of horizontal transmission (metabolic burden or host death) puts these transmission modes at odds. Using virulence-transmission trade-off (VTT) theory, we identify three groups of environmental variables affecting the balance between... -
