Insect Immunity Shows Specificity in Protection upon Secondary Pathogen Exposure
Immunological memory in vertebrates, conferring lasting specific protection after an initial pathogen exposure, has implications for a broad spectrum of evolutionary, epidemiological, and medical phenomena . However, the existence of specificity in protection upon secondary pathogen exposure in invertebrates remains controversial . To separate this functional phenomenon from a particular mechan...
متن کاملDaphnia magna shows reduced infection upon secondary exposure to a pathogen
Previous pathogen exposure is an important predictor of the probability of becoming infected. This is deeply understood for vertebrate hosts, and increasingly so for invertebrate hosts. Here, we test if an initial pathogen exposure changes the infection outcome to a secondary pathogen exposure in the natural host-pathogen system Daphnia magna and Pasteuria ramosa. Hosts were initially exposed t...
متن کاملPhagocytosis, Innate Immunity, and Host–Pathogen Specificity
In mammals, phagocytosis is essential for a variety of biological events, including tissue remodeling and the continuous clearance of dying cells. Furthermore, phagocytosis represents an early and crucial event in triggering host defenses against invading pathogens, which is the focus of this commentary. Phagocytosis comprises a series of events, starting with the binding and recognition of par...

متن کاملHost behaviour and exposure risk in an insect-pathogen interaction.
1. Studies of variability in host resistance to disease generally emphasize variability in susceptibility given exposure, neglecting the possibility that hosts may vary in behaviours that affect the risk of exposure. 2. In many insects, horizontal transmission of baculoviruses occurs when larvae consume foliage contaminated by the cadavers of virus-infected conspecific larvae; so, host behaviou...
