His contributions…

🔹Neisser was born in Poland and his father was a physician. Neisser did his schooling along with another great name in the history of medicine – Paul Ehrlich.
🔹Then, Neisser enrolled to study medicine at the University of Breslau and graduated in 1877. 
🔹After his studies, he joined to work as an Assistant to the Dermatologist. There he concentrated on sexually transmitted diseases and leprosy.
🔹He further conducted his research on pathogen for gonorrhea but it took two years of time to obtain experimental evidence .
🔹Thereafter, he made an effort to make use of a new Zeiss microscope with oil-immersion system. He was the first who observed the “micrococcus.” Later, it was renamed as “Gonococcus” by his friend Dr. Paul Ehrlich. 
🔹He published his discovery of causative organisms of Gonorrhoea in 1879 at the age of 24 years. It became a milestone in elucidating the aetiology of venereal diseases
🔹Soon after his discovery, he made a research trip to Norway in 1879. There he worked with the Norwegian physician Dr. Gerhard Armauer Hansen.
🔹Thereupon, he successfully stained the Lepra bacilli from the tissue samples of the patients of Dr. Hansen’s. Thereby, Dr. Neisser became the co-discoverer of the causative agent of leprosy.
🔹Afterwards, Dr. Neisser collaborated with a German bacteriologist Dr. August von Wassermann, and developed the famous diagnostic test for detecting Treponema pallidum infections and named as Wassermann test.
🔹He then collaborated with Dr. Paul Ehrlich and discovered the first chemotherapeutic agent Salvarsan for syphilis in 1910.
🔹His Eponyms….
🔅 Neissericeae – A family of bacteria that are spherical, gram-negative, nonmotile. The two genera are Neisseria and Veillonella.
