Purpose of biochemical tests in microbiology - think, that
The biochemical tests in microbiology they are a set of chemical tests that are made to the microorganisms present in a sample in order to identify them; These microorganisms are usually bacteria. There is a large number of biochemical tests available to a microbiologist. However, the choice of these tests is based on preliminary findings, such as the Gram stain pattern and growth characters, which allow the bacteria to be assigned to a particular category. The biochemical tests are based mainly on the metabolic properties of each type of bacteria. Not all bacteria have the same properties, so it is investigated if they have any particular enzyme by adding the substrate and waiting for the reaction to occur. Commonly this determination is given by a change of color or pH in the culture medium. Often less than 15 biochemical tests are required for the reliable identification of a bacterium up to the species level.

.Staphylococcus aureus is a Gram-positiveround-shaped bacteriuma member of the Firmicutesand is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin.
It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen. Pathogenic strains often promote infections by producing virulence factors such as potent protein toxinsand the expression of a cell-surface protein that binds and inactivates antibodies.

The emergence of antibiotic-resistant strains of S. Despite much research and developmentno vaccine for S. It is still https://digitales.com.au/blog/wp-content/custom/general-motors-and-the-affecting-factors-of/which-is-the-control-center-for-the-endocrine-system.php of the five most common causes of hospital-acquired infections and is often the cause of wound infections following surgery. Each year, aroundpatients in hospitals of the United States contract a staphylococcal infection, chiefly by S. InSir Alexander Ogstona Scottish surgeon, discovered that Staphylococcus can cause wound infections after noticing groups of bacteria in pus from a surgical abscess during a procedure he was performing.
He named it Staphylococcus after its clustered appearance evident under a microscope. Then, inGerman scientist Friedrich Julius Rosenbach identified Staphylococcus aureusdiscriminating and separating it from Staphylococcus albusa related bacterium.
In the early s, doctors began to use a more streamlined test to detect the presence here an S. Prior to the s, S. However, doctors discovered that the use of penicillin could cure S.
Unfortunately, by the end of the s, penicillin resistance became widespread amongst this bacterium population and outbreaks of the resistant strain began to occur. Staphylococcus aureus can be sorted into ten dominant human lineages. There are numerous minor lineages biochemica, well, but these are not seen in the population as often.]
