As of 13 January 2021, there have been 3 113 963 confirmed cases SARS-CoV-2 and 74 619 deaths across the African continent. Despite relatively lower numbers initially, many countries are now experiencing an exponential increase in case numbers.

<h2>Summary</h2><h3>Background</h3> Accurate detection of antimicrobial resistance (AMR) depends on adequate laboratory capacity. We aimed to document key weaknesses hindering AMR at various tiers networks in 14 countries sub-Saharan Africa, and analyse their significance surveillance policies. <h3>Methods</h3> In this analysis, we obtained retrospective data consumption from participating the Mapping Antimicrobial Resistance Use Partnership between May 1, 2019, June 30, 2020. established...

Abstract Objective The purpose of this analysis was to describe national critical care capacity shortages for 52 African countries and outline needs each country adequately respond the COVID-19 pandemic. Methods A modified SECIR compartment model used estimate number severe cases at peak outbreak. Projections hospital beds, ICU ventilators needed outbreak were generated four scenarios – if 30, 50, 70, or 100% patients with symptoms seek health services—assuming that all people infections...

Tissue culture technology of cassava (Manihot esculenta Crantz) is a viable alternative to currently adopted techniques for mass propagation, germplasm conservation and genetic improvement. However, somaclonal variation common phenomenon in tissue which makes it mandatory monitor the stability plants. Therefore, objective this study was evaluate plants regenerated from axillary bud explants through direct organogenesis using simple sequence repeat (SSR) markers. High shoot regeneration (81.2...

Abstract Background Antimicrobial resistance (AMR) is one of the greatest global health challenges today, but burden assessment hindered by uncertainty AMR prevalence estimates. Geographical representation estimates typically pools data collected from several laboratories; however, these aggregations may introduce bias not accounting for heterogeneity population that each laboratory represents. Methods We used up to 381 laboratories in United States The Surveillance Network evaluate methods...
