Streptomycetes are a member actinomycete family. Streptomycetes are usually found in soil and are important decomposers. They are aerobic, gram-positive, filamentous rods that create branching hyphae. They also produce more than half of the world's antibiotics, and are therefore very valuable in... 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
