C. botulinum (botulinum toxin) is defined as a biothreat level A organism by the Centers for Disease Control and Prevention 7. Category A organisms are considered to pose the greatest threat to national security.
Clostridium botulinum is a slightly curved Gram-positive, sporulating motile rod [4], producing seven distinct (A—G) neurotoxins, which are the most toxic

Despite the potency of its neurotoxin, the noninvasive and noncontagious C. botulinum has been graded as a class II pathogen. Appropriate biosafety level 2 containment facilities and trained personnel are therefore a minimum requirement for work with C. botulinum.
Can clostridial bacteria cause botulism?
Other clostridial bacteria can also produce the toxin leading to botulism.
Despite its potential fatality and rarity, the illness can masquerade as other illnesses making the diagnosis difficult.
Several studies show that the secretion of the submandibular gland (SMG) inhibited by botulinum toxin A (BTXA).

How Does The Illness occur?
Once in the body, the toxin binds to nerve endings that join muscles.
This prevents the nerves from signaling the muscles to contract.
The first symptoms of botulism are nausea, vomiting, weakness, and vertigo (dizziness).
These are followed by neurological symptoms: visual impairments (blurred or double vision), loss of normal throat and mouth fun.
What Are The Symptoms?
Symptoms of botulism usually appear within 12 to 36 hours after eating food containing the neurotoxin, although there have been documented cases that ranged from 4 hours to 8 days.
The earlier the symptoms appear, the more serious the disease.
Treatment requires quick medical attention and an antitoxin.
What is Clostridium botulinum?
Clostridium botulinum are rod-shaped bacteria (also called C. botulinum ).
They are anaerobic, meaning they live and grow in low oxygen conditions.
The bacteria form protective spores when conditions for survival are poor.
The spore has a hard protective coating that encases the key parts of the bacterium and has layers of protective membranes.
What Is The Best Way to Prevent Botulism?
The control of foodborne botulism is based almost entirely on thermal destruction (heating) of the spores or inhibiting spore germination into bacteria and allowing cells to grow and produce toxins in foods.
To prevent foodborne botulism:.
1) Use approved heat processes for commercially and home-canned foods (i.e., pressure-can low-acid foods such a.
