final lab practical Flashcards
how to collect fungassay sample
- clean site (lay alcohol soaked gauze over site, remove and let air dry)
- use hemostat to remove larger debris from edge of lesion
- trim off piece and make fine shavings with a scalpel
how to culture fungassay sample
inoculation: flame loop, collect sample, transfer to agar (do not bury or close lid completely to allow airflow)
incubation: room temp, monitor everyday for growth
interpretation: 2-3 days agar color change is complete; dermatophytes induce fast color changing and colonies will be small
how to make fungassasy slide from culture
- 1-2 drops pf stain on slide
- flame wire loop
- use loop to remove growth from culture
- mix with stain
- place cover slip
- 10X or 40X to look on edges of clumps
