Diagnosticum Bacterial

Diagnosticum bacterial

Bacterial diagnosticum is a preparation that is a suspension of killed bacteria of a certain type. This diagnosticum is used to carry out serological reactions to detect specific antibodies in blood serum.

Diagnosticums are prepared from antigenic strains of microorganisms by inactivating (killing) bacteria with formaldehyde or heating. As a result, bacteria lose their ability to reproduce, but retain their antigenic properties.

The use of bacterial diagnosticums allows for serological diagnosis of infectious diseases such as brucellosis, tularemia, leptospirosis, anthrax, etc. With their help, it is possible to identify both acute and past infections by the presence of specific antibodies.

Diagnosticums are produced in the form of liquid or dry preparations suitable for use in various serological reactions. They must meet certain requirements for antigenic activity and specificity. The correct use of bacterial diagnostics allows you to quickly and accurately diagnose infectious diseases.

Diagnosticum bacterial - D., which is a suspension of killed bacteria. This is a specific drug designed to clarify the nature of organic tissue. It is also a diagnostic tool that is widely used for medical purposes to identify certain strains of pathogens, as well as the properties of various substances. The bacterial diagnosticum contains a suspension of dead bacteria that contain allergens.

Diagnosticum bacterial is known as albuminalpophilic serum, since it contains specific antibodies that interact with proteins of microorganisms. This interaction can be used to recognize living bacteria by demonstrating their presence in culture. However, this technique is completely unsuitable for diagnosing bacteria of other species. Detecting a colony (detecting even one sign of growth) will result in a false positive result. This material is used to study the interaction of a substance with bacterial antibodies. When a drug is introduced into a culture of a microorganism (used as a model, for example, avidin), molecular bonds begin to form only if such antibodies are present in the sample. Thus, antigens are created to be more or less specific to the pathogen, although they can remain in solution without undergoing decay.
