The Army has added five toxins and germs to its testing of a device designed to warn troops of the presence of biological and chemical agents used against them.

Officials have been testing the "chemical biological mass spectometer" since last summer. Last week, the Army announced it was using a bacterial mist of agents causing Q fever and bubonic plague. The pathogen causing Q fever is killed before testing and the vaccine strain causing plague is weakened to where it can be injected safely in humans, Dugway spokeswoman Melynda Petries said.Initial use of the five new toxins and germs will be in liquid form as scientists place the agents in small quantities of distilled water, which will be injected into the detection equipment. Wastewater will be heated to kill any remaining biological agents.
