Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]
Simple Staining is a technique that only uses one type of stain on a slide at a time. Because only one stain is being used, the specimens (for positive stains) or background (for negative stains) will be one color. Therefore, simple stains are typically used for viewing only one organism per slide. Differential staining uses multiple stains per ...
These words may not be included in the table below if they only occur for one or two taxa. Instead, the words listed below are the common adjectives and other modifiers that repeatedly occur in the scientific names of many organisms (in more than one genus).

Eosin Y Eosin B. Eosin is the name of several fluorescent acidic compounds which bind to and form salts with basic, or eosinophilic, compounds like proteins containing amino acid residues such as arginine and lysine, and stains them dark red or pink as a result of the actions of bromine on eosin.
[1] [10] [11] When paired, this staining procedure is known as H&E staining and is one of the most commonly used combinations in histology. [1] [7] [12] [13] [14] In addition to its use in the H&E stain, haematoxylin is also a component of the Papanicolaou stain (or Pap stain) which is widely used in the study of cytology specimens. [1] [14]
A feature affecting clarity in seeing a scientific word's components is haplology, i.e. removing one of two identical or similar syllables that meet at the junction point of a compound word. Examples are: appendectomy = appendix, appendicis, (Latin for "appendix") + -ectomy (ultimately from Greek τομή, "a cutting")
Hyaline cartilage is named after its glassy appearance on fresh gross pathology. [3] On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage.
