Clue cells are epithelial cells
of the vagina that get their distinctive stippled appearance by being covered with bacteria.
They are a medical sign of bacterial vaginosis
, particularly that caused by Gardnerella vaginalis
, a group of Gram-variable bacteria. This bacterial infection gives a foul, fishy smelling yellow/grey frothy vaginal discharge
, also the vaginal pH is increased above 4.5.
You should show to a Gynecologist as asap.
