Bioterrorism is use of infectious agents or other harmful biological or biochemical substances i.e. from biological source as weapons of terrorism. It is intentional release or dissemination of biological agents. These agents are bacteria, viruses, fungi, or toxins, and may be in a naturally occurring or a human-modified form.
Antifungal agent are drugs that selectively eliminates fungal pathogens from a host with minimal toxicity towards them. Antifungal agent,also known as antimycotic drugs are pharmaceutical fungicide or fungistatic agent used to treat and prevent mycosis.
Fungi are important in various facets. Fungi degrade/ decompose complex plant and animal remains, breaking them down to simpler chemical compounds which on addition increases fertility of the soil. They are also important in industrial fermentation. Some fungi are used in processes aimed at reducing the concentrations and toxicities of waste materials particularly from industrial processes, before releasing waste to environment.
Fungi are eukaryotic, spore bearing organisms that obtain simple organic compounds by absorption. The organisms have no chlorophyll and reproduce by both sexual and asexual means. The filamentous fungi are called molds, while the unicellular fungi are called yeasts.
Mycotoxins are defined as natural products from molds that evoke a toxic response when introduced in low concentrations to vertebrates. These are toxic compounds produced as metabolic products by some molds.
They are products of secondary metabolism of molds i.e. part of metabolism that is not essential for cell growth and maintenance of basic cell functions.
