Hallier – to isolate and cultivate germs from infected tissues hinein his culture glass [ , ]. Unfortunately he interpreted the germs, isolated from humans and animals infected by gallenbrechdurchfall, typhus, gonorrhea, diphtheria, and pox computervirus, as forms of fungi polymorphism. This incorrect ausdeutung was rejected by the mycologists de Bary and Brefeld and bacteriologists such as Cohn, Rindfleisch, and Burdon-Sanderson [ 35 , 36 ].

The crucial experiments showing that one distinctive species causes a wohnhaft specific infectious disease were performed by Robert Koch – The decision to select milzbrand for the dachfirst series of experiments had been fortunate because the infected tissues contain numerous bacilli Bacillus anthracis.

Koch isolated the bacteria from in betrieb animal that died of milzbrand and reihe up cultures as part of a wohnhaft moist chamber, where the growth, ressort, and sporulation of the bacilli were observed with the microscope and documented by microphotography, which is developed by Koch . Inside the decisive experiment, edv is shown that B. The postulates comprise the verlassenheit of the microorganism from the infected tissues, the growth of the microorganism as part of pure culture using the plate and slide technique [ 69 , ], the improved methods of beobachtung using microscopy, staining and documentation of the bacteria [ 10 , 12 , ], the achievement of the typical symptoms of the disease by inoculation of the isolated bacteria into a wohnhaft sensitive host [ – ], and the einode of the same microorganism from the newly infected host.

The first success welches followed by the discovery of Mycobacterium tuberculosis as the causative ombud of tuberculosis [ , ]; of Corynebacterium diphtheriae , which causes the toxigenic disease diphtheria [] ; and of Vibrio cholerae , which causes gallenbrechdurchfall []. Rosenbach [] subdivided the geschlecht Staphylococcus into species. Hinein sument of several new techniques and the concept that specific infectious diseases are caused by distinct species of bacteria having inheritable virulence factors were the prerequisite for placing research on the etiology of infectious diseases on a valid scientific ground.

Paul Anstandig – published important articles on toxins and antitoxins and their standardization and on the specificity of antibodies against antigens [ , ]

While Koch and his coworkers and disciples were concentrating on the abgelegenheit and characterization of parasitic and saprophytic bacteria, the French school under the guidance of Pasteur was directed toward the prevention of infectious diseases. Behauptung attenuated cultures were used to inoculate animals or humans. The vaccinated individuals were shown to beryllium resistant to the ansteckend strains of fowl gallenbrechdurchfall, anthrax, swine erysipelas, or rabies [ – ]. The erkundung that carbolic acid inhibits growth of microorganisms and the aufstellung of pus within wounds [] and the numerous observations that microorganisms cause fermentation, putrefaction, and infections stimulated Joseph Lister – to develop the antiseptic system [ , ].

Inside spite of the inconsistent results of the numerous observations, the view that bacteria and other microorganisms may beryllium the causative agents of the diseases received increasing consent , pp

Na worked uberkommen procedures for treating wounds with phenolic compounds that were generally accepted and introduced into the medical practice rosette a wohnhaft long period of uncertainty. Koch and others tested many other disinfectants [ , ]. From studies on the interactions of warm-blooded bodies with inoculated parasites and the successful fight against infectious diseases, research bei the large field of immunology is initiated and the theories of humoral and cellular immunity were developed [ 29 , 35 ].

The extreme complexity of the immune gebilde was revealed altes testament the end of the 19th century.
