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 ...
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).

Koch, a pioneer in medical microbiology, worked on cholera, anthrax and tuberculosis. In his research into tuberculosis Koch finally proved the germ theory, for which he received a Nobel Prize in 1905. [5] In Koch's postulates, he set out criteria to test if an organism is the cause of a disease, and these postulates are still used today.
Diagnostic microbiology is the study of microbial identification. Since the discovery of the germ theory of disease , scientists have been finding ways to harvest specific organisms. Using methods such as differential media or genome sequencing , physicians and scientists can observe novel functions in organisms for more effective and accurate ...
Research in the 1920s and 1930s identified what appeared to be a new type of Rickettsia, isolated from ticks, that was able to pass through filters.The first description of what may have been Coxiella burnetii was published in 1930 by Hideyo Noguchi, but since his samples did not survive, it remains unclear as to whether it was the same organism.
Microbial ecology (or environmental microbiology) is the ecology of microorganisms: their relationship with one another and with their environment. It concerns the three major domains of life—Eukaryota, Archaea, and Bacteria—as well as viruses. [2] This relationship is often mediated by secondary metabolites produced my microorganism.
In microbiology, a colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in ...
