...feeds on sebum, lives in hair follicles, and is commpnly seen in older people....
1) sarcoptes scabei
2) demodex mite
3) pthirus pubis
4) pediculus corporis
No clue ,never seen that organism
basicq, demodex follicularis, a mite is the right answer, and yeah, i didn't know it either, but remember seeing it in our derm rotations in a kid. dunno how HY it is, but i guess it's something you should know about, esp since there's an infestation rate estimated to be more than 90% in aged people. It is an ectoparasite like the rest of the choices.
thank u ; today u r cming up with discoveries
