A diagram of C. tetani showing the bacterium alone, with a spore being produced, and the spore alone. Clostridium tetani is a rod-shaped, Gram-positive bacterium, typically up to 0.5 μm wide and 2.5 μm long. [1] It is motile by way of various flagella that surround its body. [1] C. tetani cannot grow in the presence of oxygen. [1]
Clostridium is a genus of anaerobic, Gram-positive bacteria. Species of Clostridium inhabit soils and the intestinal tracts of animals, including humans. [ 1 ] This genus includes several significant human pathogens , including the causative agents of botulism and tetanus .
Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1] Within bacteria, endospores are protective structures used to survive extreme conditions, including high temperatures making them highly resistant to chemicals. [ 2 ]
Both gram-positive and gram-negative bacteria commonly have a surface layer called an S-layer. In gram-positive bacteria, the S-layer is attached to the peptidoglycan layer. Gram-negative bacteria's S-layer is attached directly to the outer membrane. Specific to gram-positive bacteria is the presence of teichoic acids in the cell wall. Some of ...
Examples of bacterial species that can form endospores include Bacillus cereus, Bacillus anthracis, Bacillus thuringiensis, Clostridium botulinum, and Clostridium tetani. [6] Endospore formation is not found among Archaea. [7] The endospore consists of the bacterium's DNA, ribosomes and large amounts of dipicolinic acid. Dipicolinic acid is a ...
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.
Four species of Clostridium (Clostridium botulinum, Clostridium perfringens, Clostridium tetani, and Clostridium sordelli) are responsible for most human infections. Since Clostridium is an obligate anaerobe taxon, the bacterium infects hypoxic tissues, which have become anaerobic due to restricted blood flow , degradation of blood vessels, or ...
Clostridium tetani is durable due to its endospores. Pictured is the bacterium alone, with a spore being produced, and the spore alone. Tetanus is caused by the tetanus bacterium, Clostridium tetani. [1] The disease is an international health problem, as C. tetani endospores are ubiquitous.
