Unformatted text preview: 1/10/08 MIBO4700 Dr. Langford The most common use of the term mold/mould is a filamentous fungi in the kingdom mycota or fungi. Yeasts bud when they tend to reproduce whereas fungi tend to stick together. In candida it is common for the cells to grow to the same size as the mother cell but not completely separate, these form pseudohyphae More rounded, corners seem to be less like right angles. Dimorphism- two forms- yeast or filamentous Some people use the term polymorphous or polymorphic Candida causes yeast infections which can be trigger if general antibiotics (prescribed for acne) wipe out the normal flora in the vaginal canal. Candida is considered polymorphic because it is a yeast ( can bud), can form pseudohyphae, can form true hyphae (in the right conditions) Candida in the mouth is known as thrush, white plaques in the mouth. If it is forming true hyphae, it can get the nutrients it needs, it is more apt to invade. When the tongue is scraped, can feel like ripping out strings which are the hyphae being removed leaving small bleeding dots. over 100 species of fungi are human pathogens. Discovered because more and more people are immunosuppressed which allows the fungi to be more opportunistic. More species are known to cause diseases in plants. Fusarium, a plant pathogen, can cause human disease. [mold in bottle] dark fuzzy stuff in the bottom of the bottle is the thallus. The body of the fungus that we can see with the naked eye is known as the mycelium, anytime a fungus begins to grow it makes a thallus. Non-septate hyphae = coenocytic Can name and classify genera based on presence of hyphae....
