How might bacterial growth in a human body be similar to or different from bacterial growth on the
agar in a petric dish?

Bacterial growthon the  agar in a Petric dish:

Nutrient agar gives these assets to numerous sorts of organisms, from parasites like yeast and form to basic microorganisms, for example, Streptococcus and Staphylococcus.

The microorganisms that can be developed on complex media, for example, supplement agar can be depicted as nonfastidious life forms. Microscopic organisms are found in each natural surroundings on Earth: soil, rock, seas and even cold day off. Some live in or on different life forms including plants and creatures including people.

There is around 10 fold the number of bacterial cells as human cells in the human body. In the two people and microorganisms, a codon made of three thymine DNA-letters will code for an amino corrosive called Phenylalanine. This code is regular to the two people and microscopic organisms, and surely, for most living things.

Bacterial growth in human body is different from bacterial growth on the agar in a petri dish.

Explanation:

We know that in the human body there is the immune system which will interrupt the bacterial growth as they will be recognized as a foreign body and will be destroyed by employing immunological pathways.

Whereas on the agar medium balanced nutrient, pH, salts, amino acids and optimum temperature is provided for the bacterial growth. The desired conditions would be favorable for the  growth of bacteria.
