Question

Explain in a paragraph format some of the characteristics of microorganism and the factors that make difficult subjects to study, and why Koch’s postulate is not be true for all studied microbes.

Answer 1

Microorganisins are one of the smallest organism that can be found on the earth. These micro'organism composed of eukaryotic cells or prokaryotic cells, they can be single-celled or multicellular. The example of microbes includes algae, fungi, protozoa, bacteria as well as viruses. Koch's postulates is not be true for all studied microbes because many viruses do not causes. illness in all infected individuals. For Example: A poliovirus, which causes paralytic disease in about 17. of those infected, the fact that infection with the same vines. may lead to markedly different diseases, while different viruses may cause the same disease. Koch's postulate cannot be fulfilled for viruses that do not replicate in cell culture, or for which a suitable animal model has not been identified.
