Clostridium difficile also known as C. diff Microbiology ITT-Tech College Clostridium difficile grows without oxygen and in normal temperature of 98.6 that is why the body makes a perfect host. C.difficile exists in two states-the vegetative (growth) state or the spore state. In the vegetative state the bacterium is able to use nutrients to grow and divide. When conditions become unfavorable‚ C.difficile is able to enter a dormant state and form a highly resistant spore. When conditions become

maggot therapy mechanisms of action Medicinal maggots have at least two confirmed beneficial effects on wounds that can be supported by laboratory investigations. They are debridement‚ or elimination of necrotic tissue‚ and removal of pathogenic bacteria. There is moreover‚ evidence from recent studies that they may also accelerate wound healing by promoting the formation of granulation tissue as suggested by the early literature‚ Wound debridement activity Necrophagous larvae feed on the dead
