Parasitic fungi

Many parasitic fungi have been shown to produce toxins however, the toxins of Aspergillus and PeuirHHum have perhaps the greatest potency against humans. 

Plant compounds and products of decay also may affect saprophytic and parasitic fungi. Rennerfelt and Nacht (20) noted that heartwoods of pines have a fairly high fungicidal resistance, while those of some other conifers do not. They were able to extract, isolate, and identify eight heartwood compounds (from four species) which had fungicidal... 

T cells The type of lymphocyte responsible for cell-mediated immunity also protects against infection by parasites, fungi, and protozoans and can kill cancerous cells circulate in the blood and become associated with lymph nodes and the spleen. 

Natural and biological extraction [16], The active ingredients for some important drugs are sometimes isolated from natural sources such as plants, roots, parasitic fungi, or animal glands. Medicines such as insulin, morphine, anticancer drugs, and others with unique properties are produced by natural product extraction [16].

Cordyceps capitata C. ophioglossoides (2, Note 4) These parasitic fungi are relatives of ergot reportedly used in mushroom curing rituals in Mexico (Guzman 1958 Heim 1957A). Although preliminary chemical studies found the former species to be devoid of psilocybine and psilocine, it was found to contain traces of a different indolic substance (Heim Wasson 1958) which, alas, has not yet been identified. 

Information on the time of survival of these obligate parasites is now uncertain because some of them can grow on the roots of plants other than their usual host, and may or may not produce visible lesions. If there is no visible evidence of the presence of the pathogen on a non-host plant, such as a weed, it is extremely difficult to detect the presence of the parasite. It is possible and probable that some obligate parasitic fungi feed on the exudates from non-host plants and by this means obviate the necessity for root penetration in order to survive. 

Infectious substances are those that contain viable micro-organisms that are known or assumed to cause diseases in humans or animals. The viable microorganisms include bacteria, rickettsia, parasites, fungi, and recombined, hybrid, or mutated micro-organisms. 

The heading of Class 6.2 covers infectious substances. Infectious substances are those substances known or reasonably expected to contain pathogens. Pathogens are defined as micro-organisms (including bacteria, viruses, rickettsia, parasites, fungi) or recombinant micro-organisms (hybrid or mutant), that are known or may be reasonably expected to cause infectious disease in animals or humans.
