Capua et al. suggest that medical and veterinary virologists investigate the cross-reactivity and pandemic potential of animal H1, H2, and H3 subtypes along with other recognized potential pandemic subtypes in efforts to improve pandemic preparedness efforts globally.

Zakhour et al. determine that the cow virus should not infect humans or pigs, finding that a cow-specific strain binds very specifically to the so-called xenoantigen, present only at the surface of the small intestine of cows.
Roy et al. propose that it is possible that cross-species transmission events may have contributed to the natural evolution of adenoviruses found to infect humans today, based on sequence data of 30 different adenoviruses from great apes.
John et al. use live imaging by 2-photon microscopy to identify a very early window of time during infection when dendritic cells and T cells make sustained contacts with one another, and where the most substantial changes are, in immune responses against Toxoplasma gondii.
PLoS Pathogens is an open-access journal that publishes important new ideas on bacteria, fungi, parasites, prions, and viruses that contribute to our understanding of the biology of pathogens and pathogen-host interactions.
