A Comparison of Three Different Bioinformatics Analyses of the 16S –23S rRNA Encoding Region for Bacterial Identification
Conclusion The higher resolution at the species level identification provided by 16S–23S rRNA encoding region NGS makes its use in routine diagnostic microbiology potentially attractive. Particularly, data analysis is one of the most important steps of a diagnostic workflow, which requires an optimal pipeline for the interpretation of the sequencing data in a short time. This study demonstrates that de novo assembly and subsequent BLASTN analysis using an in-house developed database compared to OTU clustering and mapping approaches is the most accurate and fastest approach for identification of bacterial pathogens....

Isolation of Antimicrobial Compounds From Cnestis ferruginea Vahl ex. DC (Connaraceae) Leaves Through Bioassay-Guided Fractionation
Conclusion In conclusion, aqueous extracts of C. ferruginea leaves showed antimicrobial activity due to the presence of hydroquinone and caffeic acid methyl ester. This supports its traditional use for infections and confirmed that the active molecules are water-soluble. Author Contributions KK, SP, LVP, and WL conceived and designed the experiments. SP, KK, M-RY, and J-GL performed the experiments. SP, LVP, WL, M-RY, J-GL, and Z-HJ analyzed the data. WL and Z-HJ contributed reagents, materials, and analysis tools. KK, SP, WL, M-RY, Z-HJ, and LVP contributed to the writing of the manuscript. All authors contributed to m...
