A poisonous substance produced by an organism or within living cells. A poison of animal, vegetable, or microbial origin.
Specific, characterizable, poisonous chemicals, often proteins, with specific biological properties, including immunogenicity, produced by microbes, higher plants, or animals.
A poisonous product produced by microorganisms.
A substance (e.g., produced in some cases by disease-causing microorganisms) which is poisonous to certain other living organisms.
Substance that is poisonous to the body.
A poisonous substance. Toxins are usually proteins produced by living cells or organisms that are capable of causing disease when released into body tissues. Toxins are commonly produced by microorgansims such as bacteria; examples include the microorganisms that cause anthrax, cholera, dysentery, diphteria, and botulism.
Poisonous substances, a term often used to refer to substances produced by microorganisms, either through their metabolic activity or through their death and decomposition.
A poisonous substance produced in the body by microorganisms, and which, if injected into an animal, stimulates the production of antitoxins.
Harmful substances which are present naturally or enter foods adventitiously, or are elaborated in them by bacteria or moulds.
Chemicals that elicit symptoms of poisoning.
Poison, especially one produced or occurring in a plant or microorganism.
A poisonous metabolic product of a living organism, usually of disease-causing microorganisms such as bacteria.
A poison produced by a living organism, especially by a bacterium. In the body toxins act as antigens, and special antibodies (antitoxins) are formed to neutralize their effects.
Poisons produced by bacteria. Toxins are usually soluble, easily destroyed by heat. Sometimes of the nature of crystalline substances, and sometimes albumins. When injected into animals in carefully graduated doses, they bring about the formation of substances called antitoxins which neutralize the action of the toxin. These antitoxins are generally produced in excessive amount, and the serum of the animal, when withdrawn, can be used for conferring antitoxic powers upon other animals or human beings to neutralize the disease in question. The best known of these antitoxins are those of diphtheria and tetanus. Toxins are also found in many plants and in snake venom.
Various poisonous substances produced by some microorganisms (bacteria and viruses).
This refers to a naturally occurring compound that acts at a low concentration and has harmful and irreversible effects on the regular functions of a living organism. Typically, this term is used to describe compounds that are produced by other living organisms.
A toxic substance, originating from either a microorganism, plant, or animal, possesses the capability to cause harm or illness when encountered. These poisonous substances, commonly known as toxins, can be generated by a variety of sources in nature. Microorganisms, such as certain bacteria or fungi, as well as specific plant species and various animals, have the ability to produce these hazardous substances. When exposed to these toxins, individuals may experience adverse effects ranging from mild discomfort to severe illness, highlighting the importance of recognizing and avoiding such potentially harmful agents.
A toxic protein generated by disease-causing bacteria, certain animals, or select plants. Bacterial toxins are occasionally categorized into three groups: endotoxins, which are released from deceased bacteria; exotoxins, which are released by living bacteria; and enterotoxins, which provoke inflammation in the intestine.
A toxic substance produced by animal or plant cells that, when injected into animals or humans, stimulates the production of antibodies known as antitoxins. The most significant toxins are those created by higher plants, certain animals, and disease-causing bacteria.
