Editing Antitoxin (section)

== History of antitoxin ==
Antitoxins to [[diphtheria toxin|diphtheria]] and [[tetanus toxin]]s were produced by [[Emil Adolf von Behring]] and his colleagues from 1890 onwards. The use of [[diphtheria antitoxin]] for the treatment of diphtheria was regarded by ''[[The Lancet]]'' as the "most important advance of the [19th] Century in the medical treatment of acute infectious disease".<ref>{{cite journal |title=Report of the Lancet special commission on the relative strengths of diphtheria antitoxic antiserums |journal=Lancet |year=1896 |volume=148 |issue=3803 |pages=182–95 |doi=10.1016/s0140-6736(01)72399-9 |pmc=5050965}}</ref><ref>{{cite journal |last=Dolman |first=C.E. |title=Landmarks and pioneers in the control of diphtheria |journal=Canadian Journal of Public Health |year=1973 |volume=64 |issue=4 |pages=317–336 |pmid=4581249}}</ref>

In 1888, Behring was sent to Berlin for a brief service at the Academy for Military Medicine. In 1889, he joined the Institute for Hygiene of the [[University of Berlin]], then headed by [[Robert Koch]]. Between 1889 and 1895, Behring developed his pioneering ideas on [[serum therapy]] and his theory of antitoxins.<ref name=":0">{{cite web |url=http://www.encyclopedia.com/topic/Emil_von_Behring.aspx |title=Emil von Behring Facts, information, pictures |website=www.encyclopedia.com |access-date=2016-05-17 |df=dmy-all}}</ref>

Early 1887, in Bonn, Behring had found that the serum of tetanus-immune white rats contained a substance that neutralized anthrax bacilli. He recognized this as the source of their "resistance".<ref name=":0"/> On 4&nbsp;December 1890, Behring and [[Kitasato Shibasaburō]] published their first paper on [[serum therapy|blood-serum therapy]].<ref name=":0"/> On 11&nbsp;December, another report, signed by Behring, discussed blood-serum therapy not only in the treatment of tetanus, but also in diphtheria.{{citation needed|date=May 2023}}

When [[Paul Ehrlich]] demonstrated in 1891 that even [[plant toxins|vegetable poisons]] led to the formation of antitoxins in an organism, Behring's theory was confirmed.<ref name=":0"/>

Antitoxins are antibody proteins found within the serum of animals that have been injected with the toxin. Separating unnecessary proteins from the antibodies used to counter infections in medical practice is important to increase both potency of antitoxin doses and to reduced the incidence of serum sickness. [[Annie Homer]], working in Canada during the [[First World War]], undertook research into antitoxic sera, which resulted in innovative methods to manufacture high quality antitoxin protein fractions from serum.<ref name="Dakin_1917">{{cite journal |last1=Dakin |first1=H D |title=Biochemistry and war problems |journal=British Medical Journal |date=1917 |volume=1 |issue=2947 |pages=833–837|doi=10.1136/bmj.1.2947.833-a |pmid=20768628 |pmc=2348630 }}</ref>

An [[Scarlet fever serum|antitoxin]] for scarlet fever was developed in 1924, simultaneously by Raymond Dochez and [[Gladys Dick|Gladys]] and [[George Frederick Dick]].<ref>{{cite journal |last=Cushing |first=H.B. |date=August 1926 |journal=Canadian Medical Association Journal |title=Results of the use of scarlet fever antitoxin|volume=16 |issue=8 |pages=936–939 |pmid=20315893 |pmc=1709338 }}</ref><ref>{{cite journal |last=Zingher |first=Abraham |date=November 1924 |title=The Dick test and active immunization with scarlet fever ''Streptococcus'' toxin |journal=American Journal of Public Health |volume=14 |issue=11 |pages=955–962 |doi=10.2105/AJPH.14.11.955 |pmid=18011363 |pmc=1355058 }}</ref>
