What should I know about bacterial identification?
bacterial identification is a process that is used to determine the identity of specific bacteria. It is an important part of medical treatment, because many treatment procedures are strongly dependent on the identity of a particular organism causing a health problem and is also an important part of scientific research. A number of techniques are used in bacterial identification and new techniques are constantly designed to learn more about bacteria and develop new medical equipment. The isolates begin with a small swab of suspicious bacteria taken from the patient or object. The isolate is created by finding the growth medium that will support bacteria and successfully cultivate enough bacteria for study. This may be a real challenge because bacteria are very picky and will not only grow in any medium. It is also important to avoid contaminating the growth medium or sample, as this can result in confusing results.
As soon as bacteria are cultivated, a wide range of tools can be used to ensure traces of its identity. One of the most basic is a gram stain that divides bacteria into gram-positive and gram-negative bacteria using a chemical stain. Other spots can be used to increase the contrast, making it easier to see bacteria under the microscope. Visual identification under the microscope can be commonly performed with known bacterial species, especially those who have a distinctive shape.
There are multiple tools in bacterial identification. A research worker can use serological methods that include detecting a sample of unknown bacteria to different antibodies to see if the genetic code of the bacteria breaks down. The sequencing of the gene can also be used to distinguish between two closely related bacteria strains and provide information on why one strain reacts to a particular medicine, while the other does not. It is also possible to study reactions to various chemicals and stimuli,Like ultraviolet radiation.
bacterial identification is classically carried out in the laboratory because laboratories have medical equipment, chemicals and tools that can be used during monitoring the identity of the bacteria. Some laboratories specialize in cultivating and identifying samples from hospitals and medical clinics, while others focus on research and identify samples of new and unknown bacteria to be classified. The laboratory environment is firmly checked to prevent contamination and random infection of laboratory workers, with particularly virulent organisms studied in high safety laboratories that include several layers of scientists' protection.
