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.
Cellular microbiology
Recently, the field of Cellular Microbiology has been expanded to incorporate investigation of the cell biology of microbes themselves. "The field of cellular microbiology is a coalescence of two fields: molecular microbiology and cell biology," said Professor Jacek Hawiger, Chair of Microbiology and Immunology at Vanderbilt University. Particularly in the case of bacterial cells, new technology is starting to be used to reveal a high level of organization within the bacterial cells themselves. For example, high-resolution fluorescence microscopy and atomic force microscopy are both being used to show just how sophisticated bacterial cells are.
