Photograph of 400X magnified image of biogas digestor sample. A strange spiraled type microbe seen (probably like left handed DNA helix). The microbe is shown with an arrow. Has anyone seen such microbial structure? Read More
In a healthy adult human body, most internal organs such as the brain, spleen, liver, and heart are devoid of microorganisms because the immune system keeps them in check. After human host death, however, the immune system falters and microorganisms proliferate throughout the body beginning in ... Read More
