Answer:

Option (d).

Explanation:

Medicine code are used for the determination and identification of a particular medicine. The drug system and active ingredient can be easily classified by the medicine code.

Medicine code includes the manufacturer, dosage, shelf life and medicine name. The medicine name can not be treated as a determinant because it cannot affect its nature.

Thus, the correct answer is option (d).

The enteropluri test can be used to rapidly identify every type of bacteria true or false
Nutka1998 [239]

The answer is True.

<u>The correct statement:</u>

The Enteropluri test can be used to rapidly identify every type of bacteria.

What is Enteropluri test?

The 12-sector system called EnteroPluri-Test contains unique culture media that enables the identification of gram-negative, oxidase-negative bacteria like the Enterobacteriaceae.

The device enables the execution of 15 biochemical reactions as well as the simultaneous inoculation of all media available in the sectors.

Microorganisms are recognized using a code number derived from the interpretation of biochemical reaction data and by analyzing the color change of the various culture media after 18–24 hours of incubation at 36–1 °C.

The identification of Enterobacteriaceae and other gram negative, oxidase negative bacteria isolated from clinical and environmental samples is made possible by EnteroPluri-Test. Biochemical studies carried out on growth media containing particular substrates are the basis for the identification. Utilizing the Codebook to identify bacteria is made possible by the mix of positive and negative results.
