[Jules Bordet, a man of conviction. Centenary of his Nobel Prize]. / Jules Bordet, un homme de conviction - Centenaire de l'attribution de son prix Nobel.

Jules Bordet came to the Institut Pasteur soon after his MD graduation at the Université libre de Bruxelles, thanks to a grant from the Belgian government. He joined there the laboratory of Elie Metchnikoff, the father of phagocytes and cellular immunity. Amazingly, he will decipher there some of the key mechanisms of humoral immunity initially discovered by the German school against which his mentor was fighting. He described the mechanisms that govern bacteriolysis and hemolysis, following the action of immune sera. Even if he favored the term alexin coined by Hans Buchner, he is indeed one of the founding fathers of the complement system (term coined by Paul Ehrlich). It is for these works that he was awarded in October 1920 the 1919 Nobel Prize. Back in Belgium, he became the director of Institut Pasteur du Brabant and made another landmark discovery, namely the identification of the bacillus of whooping cough, now named Bordetella pertussis.

TITLE: Jules Bordet, un homme de conviction - Centenaire de l'attribution de son prix Nobel. ABSTRACT: Docteur en médecine, bénéficiant d'une bourse du gouvernement belge, Jules Bordet vint se former au sein du laboratoire du père de l'immunité cellulaire, Elie Metchnikoff, à l'Institut Pasteur. Paradoxalement, il va y déchiffrer certains des mécanismes clés de l'immunité humorale, initialement découverte par l'école allemande. Il y décrit notamment les mécanismes qui aboutissent à la bactériolyse et l'hémolyse par l'action d'immunsérums. Même s'il favorisa le terme d'alexine, créé par Hans Buchner, c'est bien le système du complément (terme inventé par Paul Ehrlich) dont il est un des pères fondateurs. C'est pour ces travaux qu'il se verra attribué en octobre 1920 le prix Nobel de physiologie ou médecine millésimé 1919. Il identifia aussi le bacille de la coqueluche, qui porte son nom Bordetella pertussis.

The Past, Present, and (Possible) Future of Serologic Testing for Lyme Disease.

Lyme disease prevails as the most commonly transmitted tick-borne infection in the United States, and serologic evaluation for antibodies to Borrelia burgdorferi remains the recommended modality for diagnosis. This review presents a brief historical perspective on the evolution of serologic assays for Lyme disease and provides a summary of the performance characteristics for the currently recommended two-tiered testing algorithm (TTTA). Additionally, a recently proposed alternative to the traditional TTTA is discussed, and novel methodologies, including immuno-PCR and metabolic profiling for Lyme disease, are outlined.

[Spotted fever and the invention of its serodiagnosis and vaccination in the Austro-Hungarian army in World War I]. / Das Fleckfieber und die Erfindung seiner Serodiagnose und Impfung bei der k. u. k. Armee im Ersten Weltkrieg.

After description of the medical institutions and epidemiological situations of the Austro-Hungarian army in World War I the provisions against spotted fever focused on louse control are discussed. The letter specified for the army had to be adjusted for the local populations. 1915 in the k.u.k. military service in Galicia Edmund Weil and Arthur Felix cultivated Proteus strains from urine of soldiers with spotted fever. As sera of such patients agglutinated these bacteria in considerable titers the investigators developed the reliable diagnostic "Weil-Felix-Test" used still today. In the same military area and time Rudolf Weigl invented the anal infection of lice. This enabled him to harvest a great amount of louse intestines containing the spotted fever Rickettsiae in their epithelial cells. Lots with defined numbers of intestines were homogenized, sterilized and used with success as vaccine for medical staff. This sort of vaccine still was used in World War II.

[The historical meaning of serological surveys as a laboratory technology applied to the immunization campaigns. The case of poliomyelitis in Spain]. / El significado histórico de las encuestas de seroprevalencia como tecnología de laboratorio aplicada a las campañas de inmunización. El caso de la poliomielitis en España.

The aim of the paper is to analyse the introduction, use and diffusion of the serological surveys, a public health technology on the borderline between epidemiology and laboratory, in connection with poliomyelitis in Spain during the Francoism period. Within the framework of the "new history" of medical technologies and innovations, the serological surveys played an important role both in the improvement of knowledge on socio-demographic distribution and the health politics arena.

The blood of the insane.

The history of serological investigations of the blood of the insane is traced from the initial such study in 1854 by a solitary Scottish asylum physician, who counted the blood cells of his lunatic patients under a weak microscope, to the January 2005 announcement by an international team of geneticists of the development of a genomic blood test that can differentially diagnose schizophrenia and bipolar disorder. The story of the first claim of the development of a blood test for madness in 1912--the Abderhalden defensive ferments reaction test--is related in detail. Studies of the blood of the insane have followed four general methodological paradigms: the corpuscular richness paradigm (1854); the metabolic paradigm (c. 1895); the immunoserodiagnostic paradigm (1906); and the medical genomics paradigm (2005).

[The proof of paternity. An andrological-forensic challenge in historical perspective]. / Der Vaterschaftsnachweis. Eine andrologisch-rechtsmedizinische Herausforderung im Spiegel vergangener Zeiten.

For centuries, difficulties have occurred in determining unresolved paternities. In addition to the modern standard methods, such as the examination of DNA or serological proof, expert opinion on fertility once played an important role. The andrological difference between incapability to fertilise and the inability to participate in sexual intercourse was also distinguished historically. Of special significance was the discovery of spermatozoa by the medical student Johan Ham in 1677 and their further investigation by Antoni van Leeuwenhoek.Recently, modern DNA methods have also been applied for historical investigations. Illustrious examples are the DNA analysis in the case of Kaspar Hauser of Ansbach and the dispute about Thomas Jefferson, President of the U.S., fathering a child by one of his slaves. In this discourse, a medicinal-forensic review of the development of expert opinion, illustrated with historical case studies, is given.

Immunofluorescence for serodiagnosis of retrovirus infection.

Indirect immunofluorescence antibody testing is a mainstay of retrovirus serodiagnosis in the public health community, affording quick, inexpensive, and clear results with significant advantages over Western blot testing. Limitations regarding training of personnel and availability of reagents will probably continue and limit indirect immunofluorescence antibody testing to the present users.
