HISTORY OF MICROBIOLOGY (LIFE SCIENCE)

1. HISTORY OF MICROBIOLOGY
PRESENTED BY
VENKATESH R

2.  Father of microbiology.
 He created an instrument which will magnify objects about
200-300 times.
 He described very little animalcules now called as
“protozoa”.
 He examined blood & some tiny microbes that are nothing
but Erythrocytes.
 In 1676 he described protozoa, algae , yeasts & bacteria.
 In 1683 he described morphological forms of bacteria , this
was the first recorded observation of bacteria.
Antony wan leewan hook(1632-1723)

3.  He developed vaccination against small pox virus.
 cow pox is a cattle disease.
 He observed cow pox was not communicable from
one to another person.
 He collected a cow pox virus. pusutle from Sarah
Nelms a dairy maid & transferred to healthy boy
James Philip. & he was infect with small pox virus.
 The boy had immunity from small pox virus.
 Jenner published his findings in june 1798.
Edward jenner
(1749-1823)

4.  He demonstrated vaccine from Anthrax disease.
 He observed that animals which die of anthrax.
 Finally he succeeded in culturing & isolating in
aqueous humour liquid from eye eyes of the cow.
 He repeated his experiment 20 times.
 Koch postulates: Discovery of tuberculosis &
smearing method of bacteria & plate method for
isolating pure cultures.
Robert koch(1843-1910)

5.  He discovered the first drugs called Antibiotics.
 That Antibiotics is called Penicillium notatum.
 One of the petri plate immediately attracted to him,
the bacterial culture there had been contaminated.
 He conducted many experiments , then he identified
a common blue green mould is called Penicillium
notatum..
 The first injection of Penicillium was given to one
person & he had acquired a staphylococcal infection.
Alexander flemming

6.  Father of medical microbiology.
 He disproved spontaneous generation theory.
 He discovered pasteurization method partially killing
microbes.
 He demonstrated rabbies vaccine , his founding is
greatly help to medical .
 He discovered aerobic & anaerobic microbes.
Louis pasteur(1822-1895)

7.  He introduced Antiseptic method.
 He chose carbolic acid (preservative)as the
microbicidial agent.
 The wounds healed in quick time by the carbolic acid
method.
 Lister applied this technique many fastering wounds
& obtained similar results.
 Later which come to known as “Lister’s antiseptic
method.”
Joseph lister(1827-1912)
