Pathogen natural history, epidemiological knowledge, human behavior and epidemic progression determine whether symptom screening and questionnaires are effective barriers to geographic spread of infection by travelers.
A model of pathogen co-evolving with host population continuously acquiring immunity is used to identify evolutionary parameters allowing pathogen population to persist without going extinct or splitting into independent lineages.
Specialized fungal pathogen populations infect rice varieties with contrasting immune systems co-cultivated in a traditional agro-system, indicating the relevance of crop diversity to restricting epidemics in the landscape.
The helical rod structure and dynamic spring-like properties of the type 1 pilus are evolutionarily fine-tuned for functioning in host-pathogen interactions during urinary tract infection and gut colonization.
Defense-related selective autophagy mediated by the antimicrobial autophagy cargo receptor NBR1/Joka2 is diverted to pathogen penetration sites to restrict plant colonization by the oomycete pathogen Phytophthora infestans.
