Microbiology
Microbiology (from Greek , "mīkros", "small"; , "bios", "life"; and , "-logia") is the study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, parasitology, mycology and bacteriology.
Acanthamoeba
Because "Acanthamoeba" does not differ greatly at the ultrastructural-level from a mammalian cell, it is an attractive model for cell biology studies; it is important in cellular microbiology, environmental biology, physiology, cellular interactions, molecular biology, biochemistry, and evolutionary studies, due to the organisms' versatile roles in the ecosystem and ability to capture prey by phagocytosis, act as vectors and reservoirs for microbial pathogens, and to produce serious human infections. In addition, "Acanthamoeba" has been used extensively to understand the molecular biology of cell motility and cancer cell dormancy by in-depth exploration of the process of encystation.
