A long-term genomic study reveals that cholera bacteria are engaged in a dynamic evolutionary struggle with viruses that infect them, influencing both disease severity and global spread. Cholera-causing bacteria are engaged in a constant evolutionary struggle with a virus that infects them, according to a new genomic study. Researchers from the Wellcome Sanger Institute, icddr,b [...]
Scientists have uncovered an unexpected way that certain bacteria manipulate plants from within. Plant-infecting bacteria have a surprisingly direct way of taking over crops. Instead of slowly breaking down defenses, many of them inject proteins straight into plant cells, effectively hijacking the system from the inside. For decades, scientists have tried to understand one particularly [...]
