Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them. The results are published today in eLife.
For a long time, researchers have worked to understand the immune reactions that take place in the human body during various illnesses, such as cancer and inflammatory disorders.
Research led by a University of Maryland team has identified the first inter-species, signalling pathway between an arthropod parasite and host, where molecules in the blood of a host animal trigger the immunity and development of a parasite.
