Home cooking can be a cost-effective and fun process. A small number of healthy people naturally carry the bacteria in their large intestines and don't have ill effects from the infection.Spores from C. difficile bacteria are passed in feces and spread to food, surfaces and objects when people who are infected don't wash their hands thoroughly. While the spores are generally harmless, the danger can occur once the spores begin to grow out into active bacteria and produce neurotoxins. Injections in the face may also cause temporary drooping eyelids. Clostridium tetani is a common soil bacterium and the causative agent of tetanus. Oxygen tolerance among these species also varies considerably with some being strict anaerobes. Clostridium botulinum is a Gram-positive, strict-anaerobic, motile, pleomorphic, catalase-negative, endospore-forming bacillus (rod) that is ubiquitously found in the soil. This strange appearance is due to the sporulation that occurs inside the cell. Once in the body the bacteria grows and produces toxins which cause the disease tetanus. The Gram stain, named after its … Without treatment, the breathing muscles will eventually become paralyzed, resulting in respiratory failure and death. It can also be present in the intestinal tracts of animals and can contaminate vegetables and fruits. Treatment requires quick medical attention and an antitoxin.
