December 2022
Article Synopsis
- The Gamma variant of COVID-19, first identified in Brazil, has been linked to higher infection rates, hospitalizations, and fatalities, especially during a surge in Minas Gerais in March-April 2021.
- A surveillance study analyzed 1,240 COVID-19-positive samples across 305 municipalities, finding that Gamma was the most prevalent variant (71.2%), followed by Zeta (12.4%) and Alpha (9.6%).
- The study emphasizes the necessity of vaccination to mitigate severe cases and deaths, noting no significant mortality differences among the different variants identified.

Filamentous bacteriophages contain a single-stranded DNA genome and have a peculiar lifestyle, since they do not cause host cell lysis, but establish a persistent association with the host, often causing behavioral changes, with effects on bacterial ecology. Over the years, a gradual reduction in the incidence of bacterial wilt has been observed in some fields from Brazil. This event, which has been associated with the loss of pathogenicity of Rasltonia spp.
