Fungal infections like athleteâs foot are challenging to treat and often require long-term courses of antifungal drugs. Why do you think fungal infections are so difficult to treat? (Hint: Think about the mode of action of antibiotics and the human host.)

For this assignment, do the following, using any RECENT resource, i.e., news about Fungi published within the last year:

3) Find an account of new information about any type of fungus that is somehow BENEFITING humans,

BE SURE to list the fungal species, the phylum to which it belongs, the specific type of effect it has, and, for the species other than human, name the species. The fungal species that you report do not have to be symbiotes, but it is perfectly acceptable to include symbiotes. Thus, each one of these four categories should be about a paragraph in length.

please DO NOT report on ANY of the folloeing fungal relationship: cheese, wine, beer making, soy sauce, bread, Mushrooms, morels, truffles or penicillin, lysergic acid, psilocybin, Ergotism or Diseases - In humans, athleteâs foot, âringwormâ, thrush, âyeast infectionâ, Histoplasmosis, and thses diseases in plants Dutch Elm disease, Chestnut Blight, corn smut, leaf rust.

Please include URLâs or relevant sources for all four postings, I would expect each will be a different article, so you should have at least four sources.

We are fighting what seems to be a losing battle against antibiotic-resistant Gram negative bacteria, such as âbeta-lactamase-producing Enterobacteriaeceaeâ (BLPE). BLPE seemed to arise all of a sudden in response to the common use of penicillin to treat infections caused by Enterobacteriaeceae.

A. BLPE are resistant to all of the following antibiotics. For each, state the antibioticâs mode of action, and explain the most likely resistance mechanism. Ceftriaxone Tetracycline Aminoglycosides Vancomycin

B. If we only overused Penicillin, how could that lead suddenly to the development of resistance to all of these different antibiotics, especially Tetracycline and Aminoglycosides?

C. BLPE can still be treated with Polymyxins. How do Polymyxins work, and why would physicians be reluctant to use them in a patient unless absolutely necessary?
