Robert Koch

Robert Koch (1843-1910)

• German physician
• He discovered the anthrax disease cycle (1876) and the bacteria responsible for tuberculosis (1882) and cholera (1883)
• Awarded Nobel Prize in 1905
• Koch and his team also developed ways of staining bacteria to improve the bacteria’s visibility under the microscope
• Determined guidelines (which are widely accepted now as Koch's Postulates) to prove that- disease is caused by specific organism
• Koch’s postulates are:
üSpecific microorganism is associated with a given disease
üMicroorganism can be isolated from the diseased animal and grown in pure culture
üCultured microbe will cause disease when transferred to a healthy animal
üSame type of microorganism can be isolated from the newly infected animal

History and Development of Microbiology

History and Development of Microbiology } 1220-1292 ; Roger Bacon postulated – disease is produced by invisible living creatures } 1483-1553; Fracastoro also suggested the same } 1632-1723; Antony van Leeuwenhoek of Holland observed and described microbes accurately as animalcules } He constructed a simple microscope composed of double convex lens with magnification of 50-300 times } 1673; He sent a detailed letter about his findings to the Royal Society of London Spontaneous Generation Vs. Biogenesis } Spontaneous generation:  living organism could develop from non-living matter e.g. maggots could be produced by exposing meat to warmth and air } 1626-1697; Francesco Redi suggested that meat did not produce maggots spontaneously.  However,  flies, attracted towards meat, laid eggs producing maggots } In 1749, John Needham observed the appearance of bacteria in meat and again supported abiogenesis } 1729-1799; Lazaro Spallanzani boiled beef broth and seale

Laminar air flow

Image
Introduction • Many medical and research facilities require aseptic working environment to carry out specialized work •  Laminar air flow Can maintain such aseptic area which is devoid of contaminants Principle •  Create particle free working environment •  By projecting air through a filtration system •  And exhausting it across a work surface •  With uniform velocity along parallel flow lines Construction • Aseptic c abinet- made up of stainless steal without gaps and joints •  Air blower- produces air flow •  Special Filtration system- Pre-filter and HEPA-filter (high efficiency particulate air filter)       •  Pre-filter- removes course particles to prevent clogging of HEPA filter       •  HEPA-filter- can  remove particles of size 0.3 µm or more with 99.9% efficiency •  Fluorescent tube- to light up the aseptic cabinet •  UV lamp- to kill the microorganisms already present inside the aseptic cabinet Working •  Dust particles  are removed from th
