Microbiology is the survey of micro-organisms which must be viewed with the assistance of a microscope or negatron microscope. The importance of microbiology includes: used in biomedical research. creative activity of medical specialties. environmental applications and new research tools. Disease doing organisms include: protists. bacteriums. viruses and other micro-organisms. Bacterias are of import for repairing N2 in a useable signifier for workss. Bacteria and some Fungis are of import in decomposition and recycling of natural stuffs. Industry applications of microbiology: waste direction. nutrient industry. excavation. medical specialty. research and biotechnology. 1660’s Robert Hooke observed micro-organisms for the first clip with a microscope and coined the term “cell” . 1632-1723 Anton new wave Leeuwenhoek credited with holding observed the first bacterium. 1828-1898 Ferdinand Cohn developed the first categorization strategy based on bacteriums form. Cohn elaborate and described the life rhythm of Bacillus.
Cohn’s Classification System:
Sphaerobacteria are spherically shaped.
Microbacteria are rod shaped
Desmobacteria are filiform
Spirobacteria are coiling shaped
1822-1895 Louis Pasteur Defined pasteurisation to forestall spoilage of nutrient by bacteriums. develop vaccinums and disproved the scientific tenet of “Spontaneous Generation” . He defined “Germ Theory” and demonstrated that sources were responsible for disease. 1843-1910 Robert Koch identified splenic fever and developed agar growing medium. Koch’s postulates was a systematic method to set up the microbic cause of disease. Ignaz Semmelweis was the first to acknowledge the demand for good hygiene during medical processs.
The first to place nosocomial infections. 1827-1912 Joseph Lister developed antiseptic methods for usage in surgery and medical specialty. 1854-1915 Paul Ehrlich developed chemotherapy to bring around infective diseases and discovers antibiotics to handle kiping illness and pox. 1881-1951 Alexander Fleming discovered penicillin and muramidase. 1864-1920 Dmitri Ivansvski discovered the first virus which is known as the baccy mosaic virus ( TMV ) . 1952 Hershey & A ; Chase Experiments identified that DNA was the familial stuff of bacteriophages. Hershey Case Experiment: utilizing phage radioactively labeled with P32 ( DNA ) or S35 ( protein ) they infected bacteriums cells. They found the P32 inside the bacteriums non S35.
