Introduction

• AMEBAE

  Phylum: Sarcomastigophora

  Subphylum: Sarcodina
• AMEBAE

  • Equipped with the ability to extend their cytoplasm in the form of pseudopods (Often referred to as false feet), which allows them to move within their environment.
• AMEBAE

  Two morphologic forms in the amoebic life cycle:

  • Trophozoites – the form that feeds, multiplies, and possesses pseudopods.

  • Cyst – the nonfeeding stage, has a thick protective cell wall designed to protect the parasite from the harsh outside environment when deemed necessary.
• AMEBAE

  • The most common means whereby amoebas are transferred to humans is through ingestion of the infective stage cyst in contaminated food or water.
