We conclude that knockdown of the genes required for proper pathogen resistance increases pathogenic infection, leading to increased dauer formation in our screen.
These associations usually appear when an opportunistic pathogen meets a host already weakened by a previous pathogenic infection [38], [39].
This may facilitate viral pathogenesis rather than replication in a manner similar to the effect of the picornavirus 3A proteins that inhibit the immune response to virus-infected cells [14] [16], ultimately leading to a more pathogenic infection [12].
Elevated plasma levels of cytokines in SIVmac251 infected animals provide additional evidence that immune activation is associated with pathogenic infection.
Importantly, SLO architecture can be disturbed as a consequence of pathogenic infection, leading to temporarily reduced responses to subsequent challenge.
We hypothesized that probiotic supplementation would boost immunity, improve antioxidant capacity, and resist severity of pathogenic infection in aging mice.
However, shrimp aquaculture production is challenged by pathogenic infection, low survival, weak larvae, and environmental problems, which results in significant loss of production (Lightner 2011).
This asymmetric response to virulence change is due to the fact that the predator species has to juggle between predation, resource competition and pathogenic infection.
"Naked DNA vaccines" allow the foreign genes to be transiently expressed in transfected cells, mimicking intracellular pathogenic infection and triggering both the humoral and cellular immune responses.
The development of efficient and low cost prophylactics to prevent pathogenic infection is given high priority in the twenty-first century.
It is well known that pathogenic infection can have a profound effect on the outcome of competition and predation, however the role of pathogenic infection in systems where predators and prey also compete for other resources is yet to be explored (i.e. in systems of intraguild predation).
