Micro Test 3b Flashcards
Fungi as infections agents
- molds and yeasts in air, dust, fomites, and normal flora
- humans relatively resistant
- fungi is relatively nonpathogenic
- only 300/100,000 linked to disease in animals
- fungi most common plant pathogen
mycoses
human mycoses caused by true fungal pathogens and opportunistic pathogens
true/primary fungal pathogens
can invade and grow in healthy, non compromised host
fungal adaption to survive in human host
ability to switch from hyphen cells to yeast cells
thermal dimorphism (need more from book)
grow as models at 30c and yeasts at 37c
Primary mycoses(mycoses)
respiratory portal, inhaled spores, enough virulence to infect healthy host
subcutaneous(mycoses)
inoculated skin, trauma, enough virulence to infect healthy host
Cutaneous and superficial(mycoses)
contaminatin of skin surface, enough virulence to infect healthy host
virulence factor(mycoses)
ability to change shape(thermal dimorphism), toxin like substances, capsules, adhesion factors, hydrolytic enzymes, inflammatory stimulants
