Anaerobic organism An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if oxygen is present. An anaerobic organism may be unicellular (e.g. protozoans, bacteria) or multicellular.

Botulism Foodborne botulism. C. botulinum is an anaerobic bacterium, meaning it can only grow in the absence of oxygen. Foodborne botulism occurs when C. botulinum grows and produces toxins in food prior to consumption. C. botulinum produces spores and they exist widely in the environment including soil, river and sea water.

Botulism Botulism is a rare but serious paralytic disease caused by a bacterial toxin usually produced by the bacterium Clostridium botulinum. There are four generally recognized naturally-occurring types; foodborne, wound, infant, and, rarely, adult intestinal colonization.

- Botulinum toxin: A toxin produced by the bacterium Clostridium botulinum that is the most poisonous biological substance known. Botulinum toxin acts as a neurotoxin.he other way is by infection with the bacterial spores that produce and release the toxin in the body (infectious botulism). The infection may occur in the intestine (intestinal botulism), as in a newborn (infant botulism), or deep within a wound (wound botulism). There is more than one type of botulinum toxin.

Botulism Neurotoxin, synthesized and secreted by Clostridium botulinum bacteria (and a few other Clostridium species), cause botulism. The toxin causes the disease by blocking the release of acetylcholine from motor nerve endings. This result produces the symptoms associated with botulism.

Toxins Bacterial Toxins. Botulinum toxin, produced by the bacteria Clostridium botulinum, is the most poisonous substance known. The bacteria grows on, e.g., poorly preserved food and causes a severe form of food-poisoning (botulism).hey usually consist of an amino acid chain which can vary in molecular weight between a couple of hundred (peptides) and one hundred thousand (proteins). They may also be low-molecular organic compounds. Toxins are produced by numerous organisms, e.g., bacteria, fungi, algae and plants.

Anaerobic infection Anaerobic infections are caused by anaerobic bacteria. Anaerobic bacteria do not grow on solid media in room air (0.04% carbon dioxide and 21% oxygen); facultative anaerobic bacteria can grow in the presence as well as in the absence of air.ixed infections caused by numerous aerobic and anaerobic bacteria are often observed in clinical situations. Anaerobic bacteria are a common cause of infections, some of which can be serious and life-threatening.

Clostridium difficile-associated disease Clostridium difficile is a Gram-positive, spore-forming rod (bacillus) that is an obligate anaerobe. It can be found in soil, water, feces, and the human gut. Infections of Clostridium difficile cause pseudomembranous colitis, toxic megacolon, perforations of the colon, sepsis, and, on occasion, death.

- Anaerobic digestion is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen.The process is used for industrial or domestic purposes to manage waste and/or to produce fuels.any microorganisms affect anaerobic digestion, including acetic acid-forming bacteria (acetogens) and methane-forming archaea (methanogens). These organisms promote a number of chemical processes in converting the biomass to biogas.

Amoebic dysentery Definition. Amoebic dysentery is caused by the protozoan parasite Entamoeba histolytica. Invasive intestinal parasitic infection can result in symptoms of fulminant dysentery, such as fever, chills, bloody or mucous diarrhoea, and abdominal discomfort.The dysentery can alternate with periods of constipation or remission.ulminant amoebic dysentery is reported to have 55% to 88% mortality. It is estimated that more than 500 million people are infected with E histolytica worldwide. Between 40,000 and 100,000 will die each year, placing this infection second to malaria in mortality caused by protozoan parasites.

Anaerobic Anaerobic bacteria are germs that can survive and grow where there is no oxygen. For example, it can thrive in human tissue that is injured and does not have oxygen-rich blood flowing to it. Infections like tetanus and gangrene are caused by anaerobic bacteria. Anaerobic infections typically cause abscesses (buildups of pus), and death of tissue. Many anaerobic bacteria produce enzymes that destroy tissue and, sometimes, potent toxins. Besides bacteria, some protozoans and worms are also anaerobic.

Clostridium botulinum From Wikipedia, the free encyclopedia. Clostridium botulinum is a Gram-positive, rod-shaped, anaerobic, spore-forming, motile bacterium with the ability to produce the neurotoxin botulinum.. botulinum is a Gram-positive, rod-shaped, spore-forming bacterium. It is an obligate anaerobe, meaning that oxygen is poisonous to the cells. However, C. botulinum tolerates traces of oxygen due to the enzyme superoxide dismutase, which is an important antioxidant defense in nearly all cells exposed to oxygen.

Botulism Botulism is a disease caused by this neurotoxin (specifically A, B, E, or F type neurotoxin); symptoms include a flaccid paralysis (weakness or slackness) in various muscles. The neurotoxin is produced by bacteria called Clostridium botulinum. The neurotoxin paralyzes muscles and can be deadly.

Anaerobic Infections Some infections are caused by bacteria that cannot survive or multiply when oxygen is present. These bacteria, called anaerobes, normally live in the GI tract, where there is only a limited amount of oxygen. Here are brief descriptions of anaerobic infections that sometimes affect children. Actinomycosis (lumpy jaw disease) is caused most often by a species of bacteria called Actinomyces.

Microbiology The Production of Toxins. Poisonous substances produced by microorganisms are called toxins; toxemia refers to the presence of toxins in the blood. The ability to produce toxins is called toxigenicity. Exotoxins are produced by bacteria (mostly gram-positive) and released into the surrounding medium. Exotoxins, not the bacteria, produce the disease symptoms. Antibodies produced against exotoxins are called antitoxins.
