Post-epidemic seroprevalence of Zika virus in Nicaragua

Researchers studied blood samples from 3,740 children and 1,074 adults in Managua, Nicaragua, after the 2016 Zika epidemic. The study found a high post-epidemic seroprevalence of 36% in children and 56% in adults, with immunity rates higher in females and increasing nonlinearly with age.

How the cholera bacterium survives water predators

The Vibrio cholerae bacterium has evolved skills to survive in aquatic environments by 'hitchhiking' on predatory amoebas and establishing a replication niche within their osmoregulatory organelle. This adaptation may have contributed to the emergence of V. cholerae as a major human pathogen.
