Deadly infectious diseases pose a prevalent danger to war fighters and warrior medics in remote, hostile areas. Infectious agents inevitably hinder the war fighters duty performance, even potentially cause mission failures. Therefore a crucial military need is to acquire the capabilities to rapidly detect the threat agents, and to expeditiously devise strategies to counter the threats. The Biomeme two3 Biomeme, Inc., Philadelphia, PA is a light 1.2 lb., hand-held, field-deployable real-time polymerase chain reaction PCR device that could meet these needs. The device is coupled to an iPhone with unique software for data analysis and transmission to intended recipients. This work reports a comparative research testing and evaluation of this system, focusing on detection of the Middle East Respiratory Syndrome Coronavirus MERS-CoV and Influenza A virus H7N9 for this assessment. Three Biomeme two3 instruments were purchased for this work. The reagents specifically designed and set in the appropriate format for Biomeme two3 and the target templates were also purchased from the manufacturer of the instrument. For MERS-CoV, the detection targets were an orf1a segment and a segment upstream of gene E termed upE. For H7N9, the target amplicons were in the H7 and N9 genes. The instrument performance was evaluated for template copy numbers that varied from 50 to 500,000 per reaction.
