It broke down often, failed to identify lethal pathogens and sometimes gave false warnings when no danger existed.

Consequently, the need to identify human pathogens was a major impetus for the development of techniques to identify bacteria.

They identify and eliminate pathogens that cause infection.

The 100K Genome Project will provide a roadmap for developing tests to identify pathogens and trace their origins more quickly.

It can also be used to identify viral pathogens in non-cancer related disease.

DTS could also apply to agriculture, identifying pathogens that have an effect on output.
