Pasteur, thus in 1858 finally resolved the controversy of spontaneous generation versus biogenesis and proved that microorganisms are not spontaneously generated from inanimate matter but arise from other microorganisms. In the later years the microorganism were picked up as ideal tools to study various life processes and thus an independent discipline of microbiology, molecular biology was born.

He compared the health outcomes for animals given chemical treatments for their parasites versus animals kept under the same conditions but given no treatment for their parasites. The 17th-century discovery of living forms existing invisible to . During this period, we see the real beginning of microbiology as a discipline of biology. microbiology, study of microorganisms, or microbes, a diverse group of generally minute simple life-forms that include bacteria, archaea, algae, fungi, protozoa, and viruses.
