Antony van Leeuwenhoek

Antony van Leeuwenhoek (1632-1723)

qFather of Microbiology
qLived in Holland
qMade more than 250 microscopes consisting of home ground lenses mounted in brass and silver; with magnification of about 200 to 300 times
qFirst to report the  single-celled organisms with accurate descriptions and drawings (“animalcules”)
q He had written 190 letters to the Society, centered around his work in microscopy
q1674- Discovered and described the alga Spirogyra, and various ciliated and flagellated protozoa
q1675- Discovered and accurately described and differentiated erythrocytes in humans, swine, fish and birds
q1677 - First to observe spermatozoa in humans, dogs, swine, birds etc
q1679 and 1684 - Described the needle-shaped microscopic sodium urate crystals that formed in the gout patients
q1683 - Observed bacteria in feces
q1683 - Found parasitic protozoa in feces (Giardia sp. and Balantidium sp.)
q1702 - Observed the ciliate protozoa Vorticella and Stentor, and the colonial protozoon Volvox in pond water

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 b...

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 alre...
