The presence of anthrax can pose significant challenges to livestock management and wildlife conservation efforts, making it a critical concern for both animal health and public health, as it can occasionally be transmitted to humans through contact with infected animals or contaminated products.
Anthrax can be transmitted between livestock, wildlife, and humans. Humans can be infected when they are exposed to infected tissue or animals, and when anthrax spores are used as a bioterrorist ...
Anthrax is a disease caused by Bacillus anthracis, a spore-forming, Gram positive, rod-shaped bacterium (Fig. 1).The lethality of the disease is caused by the bacterium's two principal virulence factors: (i) the polyglutamic acid capsule, which is anti-phagocytic, and (ii) the tripartite protein toxin, called anthrax toxin.
Anthrax spores are able to be dispersed via multiple methods and infect humans with ease. [4] The symptoms present as a common cold or flu, and may take weeks before appearing. [3] [6] The destructive effects of an anthrax attack on a large city may have the destructive capacity of a nuclear weapon. [4]
The symptoms in anthrax depend on the type of infection and can take anywhere from 1 day to more than 2 months to appear. All types of anthrax have the potential, if untreated, to spread throughout the body and cause severe illness and even death. [24] Four forms of human anthrax disease are recognized based on their portal of entry.
Anthrax disease in humans results from infection with toxin producing Bacillus anthracis strains that can be inhaled, ingested in contaminated food or drink, or obtained through breaks in the skin like cuts or scrapes. [10] Domestic and wild animals can also be infected via inhalation or ingestion.
any micro-organism, virus, infectious substance, or biological product that may be engineered as a result of biotechnology, or any naturally occurring or bioengineered component of any such microorganism, virus, infectious substance, or biological product, capable of causing death, disease, or other biological malfunction in a human, an animal ...
When the heart stops beating, blood flow is cut off from the body in a process called ischemia and a cascade of biochemical effects begins. Oxygen and nutrients are cut off from tissues. Cells ...
