Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία () 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).

Negative selection through replica plating to screen for ampicillin sensitive colonies. Replica plating is a microbiological technique in which one or more secondary Petri plates containing different solid (agar-based) selective growth media (lacking nutrients or containing chemical growth inhibitors such as antibiotics) are inoculated with the same colonies of microorganisms from a primary ...
In the table below, the images at the right indicate in blue the locations of the light organ of different families of symbiotically luminous fish and squid. [42] E indicates an external expulsion of the bioluminescent bacteria directly into the seawater. I indicates an internal expulsion of the bioluminescent bacteria in the digestive tract.
The small oval chlamydospores are 2–4 μm in diameter. Gram staining is a bacteriological laboratory technique [8] used to differentiate bacterial species into two large groups (gram-positive and gram-negative) based on the physical properties of their cell walls. [9] [page needed] Gram staining can also be used to diagnose a fungal infection ...
Colonial morphology serves as the first step in the identification of microbial species from clinical samples. [10] Based on the visual appearance of the colonies, microbiologists can narrow down the list of possible organisms, allowing them to select appropriate tests to provide a definitive diagnosis.
The votes are in. Last month, on Nov. 14, Oxford University Press narrowed a list down to six words and the world had the opportunity to vote for its favorite. Language experts from the publishing ...
A 40x magnification image of cells in a medical smear test taken through an optical microscope using a wet mount technique, placing the specimen on a glass slide and mixing with a salt solution. Optical microscopy is used extensively in microelectronics, nanophysics, biotechnology, pharmaceutic research, mineralogy and microbiology. [28]
