Clostridia are saprophytic organisms. The genus contains some of the most dangerous pathogens known to man. (Clostridium perfringens - Gangrene, Food poisoning - Clostridium botulinum - Botulism, Clostridium difficile -Pseudomembranous colitis) C tetani's tetanus toxin (known as tetanospasmin) is an anaerobic rod that is lethal, but it is not as dangerous, as the botulinum toxin produced by C. botulinum.
As with all clostridial wound infections, trauma to the host tissue is the initial event in tetanus, followed by contamination of the wound with C tetani. Without the damage to the tissue, the anaerobic bacteria cannot survive. The damage creates an environment with a potential for reduced oxidation- which is necessary for anaerobic growth. Once growth is initiated, the organism itself stays confined to the necrotic tissue, where the vegetative cells of C tetani elaborate the lethal toxin Tetanospasmin.
The incubation period for C tetani, from contamination to first symptoms depends on the site of the wound and the dose of the bacteria. The further away from the central nervous system, the longer the incubation; a large dose of bacteria in a wound in the upper arm, chest or head may only take a few days, while the infamous rusty nail to the foot - may take several weeks.
The two animal species most susceptible to this toxemia are horses and humans.

Are Puncture wounds dangerous?
Puncture wounds appear innocuous on the surface, but the underlying injury goes deep
How can antibiotics kill bacteria?
They act like a poison. Generally, poisons have a biochemical-reaction (process) target, within [or on the surface of] an organism's cell; interference in this process by the poison can be fatal.
Hershey and chase removed the phages from the surface of the bacteria by using?
They tore of the surface of the surfaces of the bacteria with the help of a blender.
How does bacterial transformation work and what are its key mechanisms?
Bacterial transformation is a process where bacteria take up foreign DNA from their environment and incorporate it into their own genetic material. The key mechanisms involved in bacterial transformation include the binding of DNA to the bacterial cell surface, the uptake of DNA into the cell, and the integration of the foreign DNA into the bacterial genome through recombination. This allows the bacteria to acquire new genetic traits and potentially gain new abilities.
What is a function of the pili found on the surface of some bacteria?
Pili, or fimbriae, found on the surface of some bacteria help attach the bacteria to surfaces or other cells, aiding in their colonization and biofilm formation. They can also be involved in DNA exchange between bacteria through a process called conjugation.
Why is ground meat more susceptible to microbial contamination than unground meat?
Ground meat has a larger surface area exposed to air and potential contaminants compared to unground meat, making it easier for bacteria to proliferate. In addition, the grinding process can mix bacteria throughout the meat, whereas with unground meat the bacteria are more likely to be on the surface and can be killed during cooking.
What is the difference between cleaning and sanitation?
Cleaning is the process of removing dirt, debris, and germs from a surface, while sanitation involves killing or reducing the number of harmful bacteria and viruses on that surface to prevent the spread of disease.
How much bacteria can contaminate the surface of a fomite?
The amount of bacteria that can contaminate a fomite (inanimate object) depends on various factors such as the type of surface, the duration of contamination, and the presence of other organic materials. Fomites can harbor enough bacteria to cause infections if they are not cleaned regularly and properly.
Is bacteria negatively charged or positively charged?
I would say, bacteria is positively charged. i suspected it was positively charged also may be, however; if it were to be negatively charged, could it still adsorb through a reversal process to a negative surface (clay for example?)
How can you prevent bacteria from growing on living things?
by killing them, or by creating a surface that is undesirable for the bacteria.
What part of the bacteria cell helps it to surface?
Pilus
What makes a tomato rot faster the light or the dark?
Tomatoes rot faster when exposed to light because light promotes the growth of mold and bacteria on the surface of the tomato, accelerating the decay process. In contrast, storing tomatoes in a dark environment can help slow down the rotting process by reducing the chances of mold and bacteria growth.
