Drivers of host-pathogen community assemblies in European forests and urban green spaces

The paper investigates how biodiversity and habitat changes affect pathogen communities in European forests and urban areas, finding that host diversity increases pathogen richness but urbanization reduces certain pathogens.

Experimental evolution of Plasmodium yoelii in single and helminth-coinfected mice

This study investigates how Plasmodium yoelii adapts to single or coinfected host environments through experimental evolution, finding no difference in virulence between evolved lines but showing adaptation to environmental context.

Host competence-abundance relationships drive the dilution effect across multiple small mammal-borne pathogens

The paper examines the dilution effect of host diversity on small mammal-borne pathogens, finding pathogen-specific patterns influenced by host competence and abundance.

Disease severity in coinfected hosts: the importance of infection order

This study shows that the order of infection with two parasites affects disease severity, with Py causing more severe symptoms after Hp infection due to impaired immune responses and increased anemia.

Coinfection with malaria alters the dynamics and fitness of an intestinal nematode

This study shows that malaria coinfection increases egg excretion and prolongs the persistence of an intestinal nematode in mice, mediated by reduced Th2 immunity.

Surveillance of zoonotic pathogens in small mammals across a gradient of forest anthropization in Eastern France

The paper surveys zoonotic pathogens in small mammals across a forest anthropization gradient, finding pathogen richness and community structure vary with host species, site, and urban adaptation traits.
