[3] He made early and significant contributions to the study of rabies, leprosy, diphtheria, tuberculosis and other infectious diseases.

[5] In childhood, Victor Babeș was always attracted to poetry, music and especially literature, as well as performance sport, natural science and dramatics.

The death of his sister, Alma, caused by tuberculosis, at a young age, led him to abandon started studies and enroll in medicine.

In 1881 he received a scholarship and went to Paris and Berlin, where he worked with leading teachers of the time: Cornil, Louis Pasteur, Rudolf Virchow, Robert Koch and others.

The same year, he discovered a parasitic sporozoan of the ticks, named Babesia in his honor (of the family Babesiidae), and which causes a rare and severe disease called babesiosis.

Later that year, he publishes the first treatise of bacteriology in the world, Bacteria and their role in pathological anatomy and histology of infectious diseases, which he co-authored with Cornil.

Babeș was the promoter of morphopathological conception about the infectious process, medical guidelines based on the synthesis between bacteriology and pathological anatomy.

Babeș was credited with inventing the first rationalized model of thermostat[3] and some methods for staining bacteria and fungi in histological preparations and cultures.

In 1887, Babeș is called in the country by Romanian government and appointed professor of pathological anatomy and bacteriology at the Faculty of Medicine in Bucharest.

He prepared the anti-diphtheria serum and conducted broad activity in researching pellagra, tuberculosis, typhoid fever and leprosy.

Victor Babeș founded the publications Annals of the Institute of Pathology and Bacteriology (Romanian: Analele Institutului de Patologie și Bacteriologie; 1889), Medical Romania (Romanian: România medicală; 1893) and Archives of medical sciences (French: Archives des sciences médicales; 1895).
