Produced in 2011, by the National Institute of Allergy and Infectious Diseases (NIAID), this photomicrographic image, created using a fluorescent light equipped microscope, depicts what were red-colored mouse macrophages 12-hours after having been inoculated with a virulent strain of green-glowing, Francisella tularensis bacteria. Please see the Flickr link below for additional NIAID photomicrographs of various microbes.
The cells on the left were untreated, while the cells on the right were treated 3 days in advance with CLDC+MPF (cationic liposome non-coding DNA complexes (CLDC) combined with crude F. tularensis membrane protein fractions (MPF)). The untreated cells fail to control replication of F. tularensis, as evidenced by their contents of the green bacteria.. In contrast, cells on the right, activated with the CLDC+MPF therapeutic, have nearly eliminated all of the bacteria.
