Horse hyperimmune antibody may help the fight against COVID-19, Brazilian study finds

Instituto Nacional de Ciência e Tecnologia de Biologia Estrutural e Bioimagem (INBEB)
Peer-Reviewed Publication

A Brazilian study has demonstrated that a hyperimmune antibody produced in horses may be an efficient approach to combat covid-19. Tests conducted in hamsters showed the ability of the treatment to reduce viral load in the pulmonary tissues, and to improve the animal clinical conditions. The neutralizing activity of the equine antibody cocktail has been proved to be high against the P.1 (Gamma) and P.2 variants.

Opportunistic bacterium increases its virulence by ‘poaching’ zinc and iron from hosts

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Researchers at the University of São Paulo have unraveled the strategy used by Chromobacterium violaceum, a pathogen found in water and soil in tropical and subtropical regions, to increase its capacity to replicate and infect host organisms. The discovery offers a route for the development of novel therapies.
