What is clue cell vs epithelial cell?

Clue cells are bacteria-covered epithelial cells that are typically found in vaginal discharge. They are a distinctive sign of bacterial vaginosis (BV), a common vaginal infection. Clue cells are identified by their appearance under a microscope as having a stippled or granulated surface due to the presence of bacteria attached to the cell surface. A high number of clue cells in vaginal discharge is a strong indicator of BV.

Epithelial cells are cells that form the surface of the skin, lining of the mouth, nose, and other organs. They’re also found in other parts of the body, such as the reproductive tract and bladder. Epithelial cells help protect underlying tissues from pathogens and may produce mucus or other secretions.

In summary, clue cells are a type of epithelial cell that is coated with bacteria and indicate an infection, while epithelial cells are a type of cell that forms a protective barrier in the body.
