Research Co-infection dynamics: one infection prohibits another in wild gourds An effective rodent Hepatitis C model Parasite traits have a greater impact on infection dynamics than parasite intensity Fugal infections alter ant behavior without invading the brain Student Profile: Not all viruses are bad! Parasite manipulation without the parasite Temperature alters Plasmodium blocking by Wolbachia Plasmodium berghei infection is enhanced by a Wolbachia strain in mosquitoes A single virus gene turns gypsy moths into zombies Within-host control of malaria dynamics Live life or die trying? The balance between being social & staying healthy during epidemics. Intensity of stress, rather than frequency or duration alone, impact immune response in lizards Variable temperatures increase amphibian disease risk Understanding within-host dynamics opens new strategies for control Testosterone increases parasite intensities in red grouse Pollen that can increase the risk of fungal infection Pathogens may influence hibernation patterns Zombie ants controlled by parasitic fungal infection Leeches may transmit pathogen to amphibians Effects of parasite communities on willow ptarmigan population dynamics Bacterial wilt and herbivory Malaria research at Penn State Virus-host interactions influence vector behavior Viruses sometimes save their hosts, rather than killing them
