Question

Which of the following protozoan attacks gums in man?

• A. Entamoeba gingivalis
• B. Trichomonas
• C. Giardia
• D. All of the above

Answer 1

The correct option is A Entamoeba gingivalis

Entamoeba gingivalis dwells in the mouth, usually between the teeth and gums. It is found in the mouth inside the gingival pocket biofilm, near the base of the teeth and in periodontal pockets. Since 90% of pyorrhoea patients harbour Entamoeba gingivalis, it is considered to be the causative agent of pyorrhoea. Hence, option A is correct answer.
