where is clostridium tetani found in the body
Clostridium tetani Clostridium tetani is a rod-shaped, anaerobic species of pathogenic bacteria, of the genus Clostridium. Like other species of genus Clostridium, it is Gram-positive, and its appearance on a gram stain resembles tennis rackets or drumsticks.[1] C. tetani is found as spores in soil or in the gastrointestinal tract of animals. C. tetani produces a potent biological toxin, tetanospasmin, and is the causative agent of tetanus, a disease characterized by painful muscular spasms that can lead to respiratory failure and, in up to 10% of cases, death.
Mycobacterium leprae Mycobacterium leprae, also known as Hansenâ€™s bacillus spirilly, mostly found in warm tropical countries, is a bacterium that causes leprosy (Hansen's disease).[1] It is an intracellular, pleomorphic, acid-fast, pathogenic bacterium.[2] M. leprae is an aerobic bacillus (rod-shaped) surrounded by the characteristic waxy coating unique to mycobacteria. In size and shape, it closely resembles Mycobacterium tuberculosis. Due to its thick waxy coating, M. leprae stains with a carbol fuchsin rather than with the traditional Gram stain. The culture takes several weeks to mature.
