What toxin is produced by Clostridium botulinum?
Botulism (“BOT-choo-liz-um”) is a rare but serious illness caused by a toxin that attacks the body's nerves and causes difficulty breathing, muscle paralysis, and even death. This toxin is made by Clostridium botulinum and sometimes Clostridium butyricum and Clostridium baratii bacteria.
Why is Clostridium botulinum used in Botox?
Botulinum toxin (BoNT), often shortened to Botox, is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis.
What does Clostridium perfringens cause?
Most people with C. perfringens infection develop diarrhea and stomach cramps within 6 to 24 hours after eating contaminated food. The illness usually begins suddenly and lasts for less than 24 hours. Diarrhea can cause dehydration, so it's important to drink plenty of fluids.
What is the clostridial toxin?
Large clostridial toxins (LCTs) are a family of bacterial exotoxins that infiltrate and destroy target cells. Members of the LCT family include Clostridioides difficile toxins TcdA and TcdB, Paeniclostridium sordellii toxins TcsL and TcsH, Clostridium novyi toxin TcnA, and Clostridium perfringens toxin TpeL.
Where is Clostridium botulinum most commonly found?
Clostridium botulinum bacteria are found in soil, dust and river or sea sediments. The bacteria themselves aren't harmful, but they can produce highly poisonous toxins when deprived of oxygen, such as in closed cans or bottles, stagnant soil or mud, or occasionally, the human body.
How many types of Clostridium botulinum are there?
Eight types of C. botulinum strains have been identified (A, B, C1, C2, D, E, F, and G ) based on the immunological differences in the toxins produced by them. All serotypes produce neurotoxin, except C2, which produces an enterotoxin.

It is produced from a culture of the Hall strain of C. botulinum and purified by a series of acid precipitations to a crystalline complex containing the toxin and other proteins. The FDA approved Botox® in December 1989 as an orphan drug for the treatment of strabismus, hemifacial spasms, and blepharospasm.
Abstract
As the leading cause of hospital-acquired diarrhea, Clostridium difficile colonizes the large bowel of patients undergoing antibiotic therapy and produces two toxins, which cause notable disease pathologies. These two toxins, TcdA and TcdB, are encoded on a pathogenicity locus along with negative and positive regulators of their expression.
INTRODUCTION
Originally named Bacillus difficilis, the organism now known as Clostridium difficile was first described in the mid-1930s ( 62 ). For the next 40 years, there were infrequent reports of C. difficile isolation, with few findings implying that this organism could cause disease. However, in 1978, C.
GENETICS OF TcdA AND TcdB
The genes encoding TcdA and TcdB, tcdA and tcdB, respectively, have been sequenced and are found in single open reading frames located within a ≈19.6-kb pathogenicity locus ( 8, 38 ). As expected, both open reading frames are large, with tcdA found within an 8,133-nucleotide region and tcdB is 7,098 nucleotides in length.
MECHANISM OF ACTION AND FUNCTIONAL DOMAINS OF TcdA AND TcdB
TcdA and TcdB utilize a well-defined mechanism of action in order to modulate cell physiology and, consequently, alter the host environment. As mentioned above, these two toxins, along with the other members of the large clostridial toxin family of toxins, target the Ras superfamily of small GTPases for modification via glycosylation.
INFLUENCE OF TcdA AND TcdB ON CELL PHYSIOLOGY
TcdA and TcdB have a dramatic influence on mammalian cell physiology, altering events ranging from cell signaling to ultrastructure maintenance. In many cases, cells do not survive intoxication by TcdA and TcdB, even at relatively low doses in comparison with other cytotoxins.
ROLE OF TcdA AND TcdB IN DISEASE
The signs of C. difficile disease range from mild diarrhea to fulminant colitis in patients undergoing antibiotic treatment. The disease occurs almost exclusively in the large bowel and shows distinguishing microscopic and gross lesions.
OTHER TOXINS PRODUCED BY C. DIFFICILE
In addition to TcdA and TcdB, a limited number of isolates have also been found to produce binary toxins that exhibit ADP-ribosyltransferase activity. Originally, C.
What is botulinum toxin?
Summary. Botulinum toxin is one of nature’s most poisonous biological substances. It is a neurotoxin produced by bacteria known as Clostridium botulinum. The neurotoxin binds to nerve terminals controlling muscles, disrupts nerve signals, and causes muscle weakness and paralysis. These effects can be harnessed therapeutically to relax spasming ...

How to use topical anesthetic?
Using a topical anesthetic can help to put a patient at ease and make the treatment process more enjoyable for the patient and the clinician. An effective topical anesthetic is benzocaine (40%)/lidocaine (6%)/tetracaine (4%) topical cream, left in place for at least 20 minutes. Simply using an ice cube for several seconds prior to injection can also be effective. Many patients, myself included, do not require anesthetic in the forehead, crow’s feet and glabella regions, however, nearly all patients require some form of anesthetic in the lip region. After providing suitable time for the topical anesthetic to work, the skin is gently cleansed of residual anesthetic cream and debris with an alcohol pad.
What is BT injection?
Injectable botulinum toxin (BT) has a variety of medical and cosmetic uses. BT causes temporarily paralysis of muscles and therefore is effective for dynamic wrinkles, i.e., the wrinkles that develop during facial expression and movement. Long-standing static rhytids, which are present when the face is at rest, will be minimally affected.
When was Botox approved?
Botox Cosmetic (Allergan) received approval in 2002 for the treatment of glabellar rhytids, which to this day remains the only FDA-approved cosmetic indication for injectable botulinum toxin; notwithstanding, it is widely used for the treatment of forehead rhytids and periocular rhytids (“crow’s feet”), among others.
Can you use BT and injectable fillers?
Often the combination of BT and injectable fillers will be beneficial. It is important to counsel patients that after the first treatment session there will almost certainly be a touch-up session; subsequent treatments should be more reliable, as the dosing is recorded and can be referenced during follow-up visits.

Scott[2] first demonstrated the effectiveness of botulinum toxin type A for the management of strabismus in humans.
Why does C. perfringens need to produce toxins?
perfringens, it is clear that C. perfringens needs to rapidly produce toxins and enzymes to break down host cell tissue to survive , as it lacks most of the machinery necessary to biosynthesize vital amino acids.
What is the disease causing agent in type B strains of C. perfringens?
Beta toxin is the main disease causing agent in type B strains of C. perfringens, which usually manifest as enterotoxemia in infantile mammals, particularly piglets, calves, foal, and lambs [11]. In humans, this condition is known as pig bel, and is not very common in most developed nations.
What is the epsilon toxin?
Produced by type B and type D strains of C. perfringens, epsilon toxin is most commonly isolated from animals, particularly sheep, goats, and cattle, but rarely from humans [15]. Similar to the other toxins, epsilon toxin creates pores in tissues, which can result in leaked potassium ions and fluid leakage, which leads to greater complications, giving way to the symptoms associated with C. perfringens infection [15]. Two common diseases seen in animals as a result from type B and D strains of C. perfringens are lamb dysentery and pulpy kidney disease [7]. These diseases are not infectious, but rather arise after some change in the gut flora of the animals, usually coupled with overeating, which leads to overly nutritious conditions very favorable for the growth of C. perfringens [7]. With this accelerated growth comes higher level of intestine destroying toxins. While most of the research for exotoxin vaccines has been directed towards the alpha toxin, there has also been some work done with the epsilon toxin. One particular study, done by Oyston et al (1998) found that a few site specific mutations of the epsilon toxin gene nullified the toxin in vivo, offering the possibility of a vaccine against epsilon toxin related disease in animals [7].
What is the alpha toxin?
