Scrabble?! CLOSTRIDIAL

Definitions of CLOSTRIDIAL in various dictionaries:

The Clostridia are a highly polyphyletic class of Firmicutes, including Clostridium and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. They are obligate anaerobes and oxygen is toxic to them. Species of the class Clostridia are often but not always Gram-positive (see Halanaerobium hydrogenoformans) and have the ability to form spores. Studies show they are not a monophyletic group, and their relationships are not entirely certain. Currently, most are placed in a single order called Clostridiales, but this is not a natural group and is likely to be redefined in the future. Most species of the genus Clostridium are saprophytic organisms found in many places in the environment, most notably the soil. However, the genus does contain some human pathogens (outlined below). The toxins produced by certain members of the genus Clostridium are among the most dangerous known. Examples are tetanus toxin (known as tetanospasmin) produced by C. tetani and botulinum toxin produced by C. botulinum. Some species have been isolated from women with bacterial vaginosis.Notable species of this class include: Clostridium perfringens (gangrene, food poisoning) Clostridium difficile (pseudomembranous colitis) Clostridium tetani (tetanus) Clostridium botulinum (botulism) Clostridium acetobutylicum Clostridium haemolyticum Clostridium novyi Clostridium oedematiensHeliobacteria and Christensenella are also members of the class Clostridia. Some of the enzymes produced by this group are used in bioremediation.
