I will pay for the following article Paul Ehrlich’s Influence on Modern Microbiology and Immunology. The work is to be 10 pages with three to five sources, with in-text citations and a reference page. The latter had for a long time been a serious disease not only in Europe but also all over the world and had developed into a serious public health problem that needed to be dealt with swiftly. Ehrlich’s contribution to microbiology, in this case, came from the study of the chemicals which were seen to have a discriminating affinity to certain types of organism or tissues and because of this research, he and a fellow scientist, Takahiro Hata, ended up developing salvarsan, an arsenical that killed spirochaete without having any mortal effects on the patients on whom it was administered. Despite the fact that this arsenical had some toxic effects, it was still a great advancement in the field of applied organic chemistry, and it was for this reason, among others, that Ehrlich was honored with the Nobel Prize for medicine in 1908.He was a pioneer in the conducting of experiments that involved the use of chemical drugs for the treatment of diseases and this was done through the study of the diverse cells and tissues in the human body. These ended up revealing the fundamental principles which lay behind the immune system of the human body and this helped a great deal on the establishment of the use of chemotherapy in medicine. In addition, his development of salvarsan ensured that syphilis would, for the first time in history, be cured and this discovery may be considered to be amongst the greatest discoveries in the modern world because it came to reveal the potential which the systematic research in drugs had for the development of cures for other diseases (Sepkowitz 291). The development of the field now known as hematology came about through the efforts of Ehrlich, who conducted studies of how blood cells reacted when the dye was applied to them. This new field came to be concerned with the study of blood and those organs which formed it, and as such came to be and is still recognized as one of the most prominent scientific fields. In fact, many of the terms which Ehrlich coined when conducting his various researches have come into common use in medicine and these involve the term chemotherapy (Elliott 53).
