Answer #1

Fungi are nongreen thallophytes or heterotrophic eukaryotic organism.

All fungi are not pathogens. Pathogenic, literally means "feeds off life". Fungi can be grouped in saprophytic (rotters), mycorrhizal (plant symbionts) and pathogenic (parasitic or disease causing). Therefore, most fungi are nonpathogenic in nature.

There are around 300 pathogenic fungal species are known for human. Candida, Aspergillus, Cryptococcus, Pneumocystis, Histoplasma, and Stachybotrys are some fungi that causing disease in humans. Cryptococcus neoformans is a example of Cryptococcus which causes severe meningitis in HIV infected people.

Some edible mushroom which are nonpathogenic in nature includes Agaricus arvensis (Horse Mushroom), Agaricus silvaticus (Pinewood Mushroom), Boletus badius, Calocybe gambosa, and Leccinum scabrum etc.

Many particles, including viruses, parasites, fungi, and bacteria, do attach to cells. Following this attachment, they may reach cellular internal milieu. However not all these particles are infectious; infectious ones may be considered intracellular pathogens. In attempting to distinguish viruses from other intracellular pathogens such as leshmania, coxiella, rickettsia, Chlamydia, mycobacterium, etc… André Lwoff and colleagues set up a rather restrictive set of rules and requirements that should be followed for pathogens to enjoy being considered viruses. One of these...

Fungi Fungi are the great decomposers of the biosphere. Most plants form mycorrhizae with fungi to increase absorptive area without having to grow more roots, in this relationship fungi recieve carbohydrates from plants. Humans consume fungi, mushrooms, may use fungi as a source of drugs for blood pressure, antibiotics and immunosuppresive drugs. Fungi are used in biotechnology to produce fermetation products, and some have been very useful models to study gentics in eukaryotic cells that are unicellular such as yeasts....
