Friedrich Julius Rosenbach, also known as Anton Julius Friedrich Rosenbach, (16 December 1842 – 6 December 1923) was a German physician and microbiologist. He is credited for differentiating Staphylococcus aureus and Staphylococcus albus, which is now called Staphylococcus epidermidis, in 1884.
Feb 10, 2016 · Additional refinement of the name streptococcus came from Friedrich Julius Rosenbach in 1884, who examined bacteria isolated from suppurative lesions, and the species was named Streptococcus pyogenes (Gr., pyo, pus, and genes, forming) (Evans, 1936).

Then, in 1884, German scientist Friedrich Julius Rosenbach identified Staphylococcus aureus, discriminating and separating it from Staphylococcus albus, a related bacterium. In the early 1930s, doctors began to use a more streamlined test to detect the presence of an S. aureus infection by the means of coagulase testing, which enables detection ...

Colony, morphological, physiological, and biochemical characteristics of marine S. epidermidisare shown in the table below. Note: + = Positive, – = Negative, W = Weakly Positive
The normal practice of detecting S. epidermidis is by using appearance of colonies on selective media, bacterial morphology by light microscopy, catalase and slide coagulase testing. Zobell agar is useful for the isolation of Staphylococcus epidermidis from marine organisms. On the Baird-Parker agar with egg yolk supplement, colonies appear small a...
Role in foot odor
A common misconception about foot odor and body odor in general is that sweat itself smells and causes people to smell. However, sweat itself is almost entirely odorless. Rather, microbes present on the skin metabolize certain compounds in sweat as a source of nutrients, producing compounds with an unpleasant smell in the process. S. epidermidis thrives in warm, moist environments and is a common bacteria of the human microbiome; it is thus primarily responsible for foot odor as feet have mor...

Friedrich Julius Rosenbach (1842-1923) studied medicine and bacteriology at Heidelberg, Göttingen, Vienna, Paris, and Berlin, earning an MD in 1867. In 1884 he published Mikro-Organismen bei den Wund-infections-krankheiten des Menschens while also isolating and naming Streptococcus pyogenes, the infectious agent in "scarlet throat," and ...
In 1884, Friedrich Julius Rosenbach identified the Staphylococcus aureus strain from a related bacterium. Before 1940, infections with this pathogen were fatal. However, as penicillin was developed, doctors found that it could cure S. aureus infections.
