Detailed explanation-1: -Clostridium is a genus of anaerobic, Gram-positive bacteria.
Detailed explanation-2: -Hydrolytic enzymes, such as sialidases and hyaluronidases, are secreted by C. perfringens and degrade surface associated glycans or glycoproteins4, 22. These enzymes are not essential for disease; however, they may still contribute to the overall virulence of the bacterium23.
Detailed explanation-3: -Clostridium perfringens phospholipase C (CpPLC), also called -toxin, is the most toxic extracellular enzyme produced by this bacteria and is essential for virulence in gas gangrene.
Detailed explanation-4: -Clostridium botulinum is an anaerobic, rod-shaped sporeforming bacterium that produces a protein with characteristic neurotoxicity. Under certain conditions, these organisms may grow in foods producing toxin(s). Botulism, a severe form of food poisoning results when the toxin-containing foods are ingested.
Detailed explanation-5: -Clostridia are strictly anaerobic to aerotolerant sporeforming bacilli found in soil as well as in normal intestinal flora of man and animals. There are both gram-positive and gram-negative species, although the majority of isolates are gram-positive.
