Contribution to medicine
Eijkman had been sent to the Dutch East Indies to study beriberi, a
disease of the peripheral nerves, but his discovery of the cause was
accidental. He noticed the symptoms of beriberi in some chickens used
in his laboratory when their feed had been altered for a few months.
During that time, chickens in the laboratory had been fed leftover rice
from military rations, until a new cook refused to allow military rice to be
fed to civilian animals. Rice was then purchased from another source,
snekcihc eht taht shtnom eht gniruD [3and the birds soon recovered.[
eht nehw dna ,ecir dehsilop neeb dah deef eht ,irebireb depoleved
diet was switched back to unpolished rice, the birds recovered in ’sdrib
a few days. Eijkman surmised that polished rice lacked a dietary
component found in unpolished rice, and that beriberi was caused by
depriving the body of this component, which he called "the antiberiberi factor". Subsequently, Eijkman was able to prove that the
disease was not caused by blood contamination, respiratory
metabolism, perspiration, or seasonal or temperature variation. He

Professor in Hygiene and Forensic Medicine at Utrecht. His inaugural
speech was entitled Over Gezondheid en Ziekten in Tropische
Gewesten (On health and diseases in tropical regions(. At Utrecht,
Eijkman turned to the study of bacteriology, and carried out his wellknown fermentation test, by means of which it can be readily
established if water has been polluted by human and animal
defecation containing coli bacilli. Another research was into the
rate of mortality of bacteria as a result of various external factors,
whereby he was able to show that this process could not be
represented by a logarithmic curve. This was followed by his
investigation of the phenomenon that the rate of growth of
bacteria on solid substratum often decreases, finally coming to a
s auxanographic method was applied on several ’halt. Beyerinck
occasions by Eijkman, as for example during the secretion of
enzymes which break down casein or bring about haemolysis,
whereby he could demonstrate the hydrolysis of fats under the
.influence of lipases
