Relative host body condition and food availability influence epidemic dynamics: a Poecilia reticulata-Gyrodactylus turnbulli host-parasite model.

abstract：:Due to shared characteristics with snail haemocytes, the Biomphalaria glabrata embryonic (Bge) cell line has been used as a model in vitro system for the study of snail-trematode interactions. In this study, Bge cells were used to characterize the adherence of snail host cells to schistosome primary sporocysts, and to...

The role of infection on female mate choice in mammals was assessed using a 3-chambered apparatus. A female CD-1 mouse was allowed to choose between 2 tethered male mice, 1 uninfected and 1 i...
