Unlabelled: Bioprospecting can uncover new yeast strains and species with interesting ecological characteristics and valuable biotechnological traits, such as the capacity to convert different carbon sources from industrial side and waste streams into bioproducts. In this study, we conducted untargeted yeast bioprospecting in tropical West Africa, collecting 1,996 isolates and determining their growth in 70 different environments. While the collection contains numerous isolates with the potential to assimilate several cost-effective and sustainable carbon and nitrogen sources, we focused on characterizing the 203 strains capable of growing on lactose, the main carbon source in the abundant side stream cheese whey from dairy industries.

- The study focuses on the emergence and dissemination patterns of the SARS-CoV-2 B.1.1.318 and B.1.525 (Eta) variants in Nigeria and Africa, highlighting their significance for public health policies during a pandemic.
- By combining genomic and travel data, the research indicates that both variants originated from within Africa, with B.1.525 emerging specifically in Nigeria before spreading globally.
- The findings emphasize the importance of understanding regional connectivity and bidirectional transmission in Africa, revealing that the risks of virus importation between countries have been underestimated.
Article Synopsis
- The study investigates the immune responses in Lassa fever (LF) survivors and their contacts in Nigeria to understand natural protection and inform vaccine development.
- It finds that while both groups show similar T cell and antibody responses, neutralizing antibodies are predominantly present in LF survivors and provide cross-reactivity against various LASV strains.
- The research also highlights that immune responses diminish over time, suggesting potential vaccine targets in specific areas of the LASV Glycoprotein and Nucleoprotein for future clinical trials.
Phytochemical analyses of guava leaf extracts, commonly applied in traditional medicine, revealed the presence of several bioactive polyphenols. In this study, we optimized the enrichment of total polyphenol from Guava leaf ethanolic extract (GEE) using six macroporous adsorptive resins (MAR) including AB8, D101, X5, ADS17, S400, and AD7. Also investigated are the contributions of adsorption time, extract concentration, pH, elution time, and eluent ethanol concentrations on the polyphenol enrichment potential of MAR.

While there are undoubtedly positive implications for adopting knowledge and practice that align with nature, there is both prevalence and ambivalence to the adoption of indigenous plant knowledge and resources for the treatment of livestock infections and diseases. This situation is due to the lack of validation and standardization of the practice in low-income countries, requiring scholarly efforts in developing this indigenous knowledge system.
