Culture media are the base where microorganisms can grow with the help of nutrients and under the influence of physical growth parameters. All microorganisms cannot grow in a single culture medium and in fact many cannot grow in any known culture medium.

Some organisms cannot grow in artificial culture medium are known as obligate parasites. Examples: Mycobacterium leprae, Rickettsias, Chlamydias, Treponema pallidum.


Selective culture media: These are specially designed culture medium made for special or any one bacteria.

Low dose of Aspirin is used for the treatment of various CVS complications including MI and High blood Pressure.  Mechanism of Action  Aspirin irreversibly acetylate the serine part of both of the COX enzymes (COX-1, and COX-2). Low dose of Aspirin is used to irreversible blocking of TXA2.  COXs are responsible for the conversion of AA to PGG2 to PGH2 and then Thromboxane A2 (TXA2) which upon binding to the TP (alpha and beta) receptor results in platelet aggregation. and induces blood clotting phenomenon.  For example: Blood clotting in the atherosclerotic plaque results in the development of Angina (unstable).   Inhibition of COXs Results decreased production of TXA2 and thus platelet aggregation does not occurs and Anginal condition may be prevented. thus decreased chances ...
