Article Synopsis
  • A study in rural Kenya found that 41% of asymptomatic residents had antibodies against the SARS-CoV-2 spike protein, and 82.5% exhibited T cell responses to multiple viral proteins, indicating some level of immunity despite not showing symptoms.
  • The immune response profile in Kenyan participants was distinct from those in Europe and Asia, exhibiting strong reactions to accessory proteins rather than structural ones and a unique cytokine balance (higher IL-10 to IFN-γ ratio).
  • These findings suggest that current methods of measuring COVID-19 prevalence may underestimate infections in asymptomatic populations, and highlight the potential influence of environmental factors on immune responses in Africa.

Background: Animal husbandry practices in different livestock production systems and increased livestock-wildlife interactions are thought to be primary drivers of antimicrobial resistance (AMR) in Arid and Semi-Arid Lands (ASALs). Despite a tenfold increase in the camel population within the last decade, paired with widespread use of camel products, there is a lack of comprehensive information concerning beta-lactamase-producing Escherichia coli (E. coli) within these production systems.

The ongoing COVID-19 pandemic highlights the need to tackle viral variants, expand the number of antigens, and assess diverse delivery systems for vaccines against emerging viruses. In the present study, a DNA vaccine candidate was generated by combining in tandem envelope protein domain III (EDIII) of dengue virus serotypes 1-4 and a dengue virus (DENV)-2 non-structural protein 1 (NS1) protein-coding region. Each domain was designed as a serotype-specific consensus coding sequence derived from different genotypes based on the whole genome sequencing of clinical isolates in India and complemented with data from Africa.

Background: Africa has one of the highest incidences of gonorrhea. is gaining resistance to most of the available antibiotics, compromising treatment across the world. Whole-genome sequencing (WGS) is an efficient way of predicting AMR determinants and their spread in the population.
