Bacteria identification in various specimens (urine, blood, stool, etc.) by culture or other method is performed to determine the cause of an infection or illness. For most routine cultures, the lab is looking for bacteria. Such cultures may also grow out fungi, and if so they too would also be reported under the same test name. But, the cultures would not be optimized for growing out fungi hence the bacteria-focused name. Therefore, a routine urine culture, for example, would be mapped to this code. One of the three domains of life (the others being Eukarya and Archaea), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls and multiply by cell division. They exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to oxygen (aerobic, anaerobic, or facultatively anaerobic) and by how they obtain their energy (chemotrophic, i.e. via a chemical reaction or phototrophic, via a light reaction). In addition, chemotrophs obtain their energy from chemicals, lithotrophic from inorganic compounds and organotrophic from organic compounds. Bacteria are also classified by the source carbon that they utilize: heterotrophic, from organic sources or autotrophic, from carbon dioxide. They can also be classified by whether or not they stain (based on the structure of their cell walls) with crystal violet dye: gram-negative or gram-positive.
No special preparation is needed for PEA. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing PEA. Your doctor depending on your condition will give specific instructions.
