متن کاملHost and Microbes Date Exclusively
The significant impact of commensal microorganisms on metabolism, susceptibility to disease, and general well-being of their host has become increasingly clear in recent years. Chung et al. now show that the maturation and performance of the immune system depend on organism-specific bacterial species.
متن کاملMicrobes at the host surface
The human body encounters pathogenic bacteria every day although establishment of infections after such contacts is rare. The skin and mucosal surfaces, which comprise the barrier between the body and the external milieu, are the first lines of defense, and colonization of these surfaces is normally the first step in bacterial disease. As a physical barrier, the skin is reinforced by dry, sligh...
متن کاملMicrobes can help explain the evolution of host altruism
The evolution of altruistic behaviour, which is costly to the donor but beneficial for the recipient, is among the most intriguing questions in evolutionary biology. Several theories have been proposed to explain it, including kin selection, group selection and reciprocity. Here we propose that microbes that manipulate their hosts to act altruistically could be favoured by selection, and may pl...
متن کاملDeciphering host migrations and origins by means of their microbes.
Mitochondrial DNA and microsatellite sequences are powerful genetic markers for inferring the genealogy and the population genetic structure of animals but they have only limited resolution for organisms that display low genetic variability due to recent strong bottlenecks. An alternative source of data for deciphering migrations and origins in genetically uniform hosts can be provided by some ...
