Pioneers of Bacteriology and Parasitology

developed the Gram stain, still a standard technique to classify bacteria

considered the first American bacteriologist

contributed to treating schistosomiasis, and Coxsackie viruses

was a German bacteriologist at the University of Greifswald

generally credited with inventing the device known as the Petri dish, which is named after him, while working as assistant to bacteriologist Robert Koch

He was the first to identify a bacterium that causes diphtheria

made his first notable discovery that one of the causative bacteria were Leptospira icterohaemorrhagica

In 1882 he described the tuberculosis bacillus, the same year as did Robert Koch.

differentiating Staphylococcus aureus and Staphylococcus albus

Pfeiffer is remembered for his many fundamental discoveries in immunology and bacteriology

He conducted research on tapeworms, trichinosis, and other parasites

was a Hanover-born bacteriologist best known for identifying bacillus salmonella typhi as the cause of typhoid disease in 1884

Im selben Jahr erhielt sie als erste und einzige Frau eine Anstellung bei Robert Koch

discovered the migratory route taken by the parasite Strongyloides stercoralis

Belgian bacteriologist

Fehleisen is notable as the first person to identify the cause of both erysipelas and scarlet fever as the bacterium Streptococcus pyogenes in 1883.

In 1882 he first identified Klebsiella rhinoscleromatis, an organism that is the cause of rhinoscleroma.

professor of bacteriology and microbiologist, noted for his work on pseudorabies

Albert Ludwig Sigesmund Neisser (22 January 1855, Schweidnitz, 30 July 1916, Breslau) was a German physician who discovered the causative agent (pathogen) of gonorrhea, a strain of bacteria that was named in his honour (Neisseria gonorrhoeae).

Alexandre Émile John Yersin (22 September 1863-1 March 1943) was a Swiss-French physician and bacteriologist.

Marshall and Robin Warren showed that the bacterium Helicobacter pylori (H. pylori) plays a major role in causing many peptic ulcers, challenging decades of medical doctrine holding that ulcers were caused primarily by stress, spicy foods, and too much acid.

Charles Louis Alphonse Laveran (18 June 1845-18 May 1922) was a French physician who won the Nobel Prize in Physiology or Medicine in 1907 for his discoveries of parasitic protozoans as causative agents of infectious diseases such as malaria and trypanosomiasis.

Louis Pasteur (; French: [lwi pastœʁ] ; 27 December 1822-28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, the last of which was named after him.

He is credited with the co-discovery of viruses (1898), which he called "contagium vivum fluidum".

Heinrich Hermann Robert Koch ( KOKH; German: [ˈʁoːbɛʁt kɔx] ; 11 December 1843-27 May 1910) was a German physician and microbiologist. He won the 1905 Nobel Prize in Physiology or Medicine "for his investigations and discoveries in relation to tuberculosis".

He received the 1902 Nobel Prize for Physiology or Medicine "for his work on malaria, by which he has shown how it enters the organism and thereby has laid the foundation for successful research on this disease and methods of combating it".

William Smith Tillett (July 10, 1892 in Charlotte, North Carolina, April 4, 1974) was an American internist and microbiologist. He is best known for the discovery of C-reactive protein and the streptokinase.
