Greetings!

Hi Mayooran.athithan, Piedraia hortae sounds like an interesting fungus, good luck on your assignment! C2zhaobi (talk) 22:34, 25 September 2014 (UTC) thank you (talk) — Preceding unsigned comment added by 199.189.164.9 (talk) 22:59, 25 September 2014 (UTC)

Assignment 2

Good start. There's lots of interesting stuff on this fungus. Make sure you say something about the phylogenetic position of this fungus – it's in a very unusual group for a pathogenic fungus (PMID 22679593). Also bizarrely it is sometimes deliberately grown on the hair for aesthetic purposes (Moyer DG, Keeler C. Note on culture of black peidra for cosmetic reasons. Arch Dermatol. Mar 1964;89:436). I think it's genome has been sequenced too (http://genome.jgi.doe.gov/Pieho1_1/Pieho1_1.home.html). I encourage you to look in Rippon's book because I think he might have some other interesting stories. Medmyco (talk) 17:50, 22 October 2014 (UTC)

Thank you. --SineBot (talk) 19:34, 26 October 2014 (UTC)

Suggestions

Hello Mayooran.athithan, You have a lot of good points about fungus morphology and identification, but I think it would be helpful to include the species that are most commonly infected (humans, animals?). A section dedicated to description of the fungus grown in subculture or in their natural host would also be informative. Wendyxie99 (talk) 17:56, 28 October 2014 (UTC)

Good job!

Your notes look great so far. Would love to read it once you put it all together with a taxobox.

Thank you for your suggestions to my article. You were right, I should mention a bit more pathogenicity in my article. Thanks Mayooran! JasminePrincess (talk) 08:05, 30 October 2014 (UTC)

Peer Review Suggestions

Great points so far on your article, I just have a few suggestions that may help you out and I think would be worth adding! I noticed that you didn't mention the classification of this fungus, which may be appropriate to mention. Another thing that caught my attention is that you talk about "diagnosis" but I have a feeling you meant to actually write "treatment" (Maybe read this point over again that you included). Also since piedraia hortae divides into two distinct species you might want to mention that Black piedraia is caused by Piedraia hortae and white piedraia by Trichosporon beigelii. On the topic of differentiating between two species, it might be worth noting where both species are found instead of just black piedraia. White piedraia is more common in temperate and semitropical climates, such as those in South America, Asia, Europe, Japan, and parts of the southern United States. Black piedraia usually affects scalp hair, whereas white piedraia more commonly affects pubic hair, axillary hair, beards, mustaches, and eyebrows and/or eyelashes. However, in Brazil, white piedraia is reported to affect scalp hair most commonly. White piedraia affects horses and monkeys, in addition to humans. Black piedraia occurs in monkeys and humans. Something that I found interesting was that patients who are immunocompromised, dissemination of T asahii can occur, causing purpuric or necrotic cutaneous papules and nodules. The last point I would add is that transmission might be worth discussing since the source of infection is unknown. Great job so far! Below are the links where I found the information.

Assignment 3- Comments

All of your points manage to capture the important features of your fungus. Obviously, you just have to organize them in sections which I'm sure you're working on like myself. I would just suggest to add the square brackets to some key words to provide links to other articles making yours more integrated. Also I have found two books that might help you expand on your points. The first is "Fundamental Medical Mycology" which doesn't go into too much detail, but has information on various sections including distribution, diagnosis, etc. The other is called "Molecular Detection of Human Fungal Pathogens" which goes into a lot more detail on the Piedraia genus specifically. I hope I've helped and good lick on your assignment. — Preceding unsigned comment added by Luka.m12 (talk • contribs) 02:05, 1 November 2014 (UTC)
