Viral proteins may prevent bacterial infections

... They will not harm human cells or the beneficial microorganisms that live in the nasal passages and throat and help protect against other infections. The strength and specificity of these enzymes also makes them good candidates for treating infections as well. As they are larger molecules than antibiotics, Fisc...

Full promise of genomics in disease research yet to be realized
