Robert Koch's Other
Contributions to Science
|
| |
|
Robert Koch's scientific
achievements are indeed impressive and multifaceted,
ranging from basic discoveries of bacteria as
infectious agents, to revealing the role of bacteria
in infectious disease and the possible impact on
public health. Listed below are some of Koch's major
scientific accomplishments:
 |
He showed in a
convincing way that microorganisms cause disease
in humans.
|
|
 |
|
Culture plate with bacterial colonies.
|
|
|
|
|
He established
Koch's Postulates, which provide the essential
experimental basis for any study of infectious
disease whether in humans, animals or
plants.
|
|
|
Koch developed
a technique for isolating bacteria on a culture
plate. This "Plate Technique" not only created
the foundation for bacteriological research, but
became indispensable for the study of bacterial
genetics.
|
|
|
Koch provided
the fundamentals for Microscopic Pathology.
|
|
|
He made the
first photomicrographs of bacteria.
|
|
 |
|
Slides with sample.
|
|
|
|
|
Koch was the
first to discover and describe the importance of
drying ("fixing") a bacteria-containing sample on
thin glass plates (slides). Koch's "Slide
Technique" is still the basis for routine
laboratory procedures in the study of
bacteria.
|
|
|
He discovered
and worked out the life cycle of anthrax
bacteria, and showed the importance of spores for
their survival.
|
|
|
Koch
discovered the staphylococcus, a major
disease-causing bacterium in wound
infections.
|
|
|
He isolated
and identified the bacterium that causes cholera,
Vibrio cholerae.
|
|
|
Koch was
instrumental in the development of essential
procedures and methods for disinfection and
sterilization. This was important not only for
laboratory work, but for public health measures
as well.
|
|
|
Koch was the
first to observe that healthy human beings could
be carriers of disease-causing bacteria, and
hence responsible for the spread of infectious
disease. |
