“Medical technology is an auxiliary branch
of laboratory medicine which deals with the
examination by various chemical,
microscopic, bacteriologic, and other
medical procedures, techniques which will
aid the physician in the diagnosis, study
and treatment of disease and in the
promotion of health in general.”

and that such urine has a
sweetish taste.

employed Alexandra Giliani to perform certain tasks
which would now be considered those of the

study. - Unfortunately, this young lady died of laboratory
acquired infection

invented
and improved the
compound microscope.
- Anton van
Leeuwenhoek
Anton van
Leeuwenhoek invented
and improved the
compound microscope.
* He was the first to
describe the red blood
cells, to see protozoa,
and to classify bacteria
according to shape.
17th century (1632-1723)
Observed that proteins in
the urine precipitated
when boiled with acetic
acid.
Frederick Dekkers
- Described as the “greatest” of the early
microscopist. - He was also the “Founder of Pathology”
because of his contributions in the field of
embryology and anatomy.
1628-1694 – Marcello Malphigi
- Practiced pathology
- He was the founder of the Archives of pathology in
Berlin, Germany.
1847- Rudolf Virchow
Performed the first quantitative test for urine sugar.
1848 – Hermann von Fehling
- production of aniline dyes which is used in staining
bacteria for microscopy. - Era of public health
19th century
- Discovered the concepts of
aerobic and anaerobic bacteria - Discovered that wine spoiling due
to microbes could be prevented
by partial heat sterilization
(pasteurization) at a temperature
of 55̊C – 60̊C. - Developed a vaccine against
anthrax in 1881.
1861- Louis Pasteur
- Formulated the Koch’s postulates
- Specificity of a pathogen can be established if:
- It is present in all cases
- Inoculations of its pure culture produce
disease in animals
- Inoculations of its pure culture produce
- From these cultures, it can again be obtained
- Then it can again be propagated in pure
cultures
- Then it can again be propagated in pure
Robert Koch

was established at the
University of Michigan by
Dr. Douglas.
