Introduction:
Pneumocystis jirovecii is previously known as P. carinii, is a yeast-like fungus. It causes pneumocystis pneumonia. It mainly affects immunocompromised patients, like patients with HIV. When it was called as P. carinii, it was known to cause disease in rats and human.

Twenty years ago, Pneumocystis jirovecii, a pathogen of immunocompromised patients that causes pneumonia, was classified as a protozoan because it is a chemoheterotroph that lacks a cell wall. However, taxonomists today classify Pneumocystitis as a fungus. Why do you think it was originally misclassified?
Which of the following statements about fungi is FALSE?
O 1) They may cause human disease.
O 2) fungi are photosynthetic.
O3) fungi are eukaryotes.
O 4) Fungi include yeasts and molds.
O 5) Some fungi are unicellular.
While working in a plant disease diagnostic lab, you receive a sample of a very dead tomato plant. The plant has rotted roots and the symptoms match known fungal and oomycete diseases of tomatoes. Explain one difference between true fungi and oomycetes that you could observe to determine what type of organism is killing the tomatoes?

- Streptomyces is a fungus-like bacterium common in the soil. What 4 features could you use to distinguish it from a true fungus?arrow_forwardMany fungal infections of humans are considered to be opportunistic, meaning that fungi that are normally free-living (usually in soil) can sometimes survive, and even thrive, on or inside the human body. From the fungal “point of view,” what unique challenges would be encountered when trying to survive on human skin? What about inside human lungs?arrow_forwardHealth professionals refer to fungal skin diseases as "“tineas" and name them according to the region affected. Fungal skin diseases are persistent, in part, because fungi can penetrate deeper layers of skin than can ointments and creams. There are fewer antifungal drugs than ones, and antifungals often have more severe side effects. Reflect on the evolutionary relationships among bacteria, fungi, and humans. 1. List 5 different "Tineas" to show the connection between the name and the body parts affected from them. 2. Are fungi unicellular or multicellular organism? 3. Why it is harder to fight fungi than bacteria? 4. Why antifungals have more severe side effects?arrow_forward
- In humans, fungi can only infect the skin.True or false?arrow_forwardThe fungi were once grouped with plants. What was the basis for this? Cite examples of fungi that are important in the following: Food security Wine industry Biological warfarearrow_forwardThe police had two individuals that they were considering as suspects responsible for a crime. They asked the forensic team to look for other evidence that might link one of the suspects to the crime scene. Luckily the forensics team was able to isolate fungal spores from the shoes of each suspect for further analysis. What technique could the researchers use to microscopically observe and compare the vegetative and reproductive structures from fungi found on the shoes? Only name the technique.arrow_forward
- A worker involved in demolishing an older downtown building is thevictim of a severe lung infection.a. Without any lab data, what two fungal infections do you suspect?b. What is your reasoning?c. How would you differentiate them?arrow_forwardChytrids, a group of fungi with flagellated spores, include somebasal lineagesarrow_forwardYou have been asked to consult for a biotech company that is seeking to understand why some fungi can live in very extreme environments, such as the high temperatures inside naturally occurring hot springs. The company has isolated two different fungal species, F. cattoriae and W. gravinius, both of which can grow at temperatures exceeding 95°C. The company has determined the following things about these fungal species (see attached image) By sequencing and examining their genomes, the biotech company hopes to understand why these species can live in extreme environments. However, the company only has the resources to sequence one genome, and would like your input as to which species should be sequenced and whether you believe a shotgun strategy will work in this case.arrow_forward
- Fungi tend to reproduce sexually when nutrients are limited or other conditions are unfavorable, but they reproduce asexually in more ideal conditions. Why is this strategy successful? Need referencearrow_forwardAre all fungi detrimental for other organisms? Explain why if yes or noarrow_forwardWhich of the following statements about fungi is false?a) Fungi may cause disease when growing in or on the human body.b) Some fungi produce toxins that can kill humans.c) Fungal spores may cause allergic responses in humans.d) Systemic mycoses are common in otherwise healthy adults.arrow_forward
