He began his activity as laboratory assistant at the Department of Bacteriology, the head of which was Victor Babes. In Paris he was laboratory assistant at the Department of Immunology.

He continued his studies of immunity with Ehrlich in Germany. On his return to France, Levaditi was admittedÂ to the Â«Pasteur InstituteÂ» by Metchnicoff, who guided him in his experiments in the field of phagocytosis.
Levaditi had significant contributions in papillomavirus oncolytic virus, syphiligraphyÂ and chemotherapy. In heÂ demonstrated, in cooperation with Karl Landsteiner, the presence of the poliovirus in other tissues than in the nervous one, namely in the nasopharyngeal secretions, in the salivary glands and in the intestinal lymph nodes. InLevaditi isolated the poliovirus on a tissue explant, defined the histopathology of the experimental disease and demonstrated the ultrafiltrability of the poliovirus.
Already in he tried to applyÂ the chemoprophylaxis of the disease by intranasal route, a problem of actuality for the rhinoviruses. AfterLevaditi, assisted by Nicolau, elaborated at the Department papillomavirus oncolytic virus Bacteriology of the Faculty of Medicine in Cluj projects related to the study papillomavirus oncolytic virus other viruses: herpesviruses, vaccine virus and rabies virus group.
Â The investigations performed from rabies outlined an important chapter of the virological research on: the neurotropic ectodermoses. Levaditi introduced the term Â«neuroprobasiaÂ», which defines the progression of viruses along the nerve tracts. Levaditi in cooperation with P. Lepine coordonated two of the first treatises of virology: Â«Les ultravirus des maladies humainesÂ» Â«Ultraviruses of human diseasesÂ» and Â«Les ultravirus des maladies animalesÂ» Â«Ultraviruses of animal diseasesÂ» Levaditi had remarkable disciples in France Pierre Lepine, M.
Nicolau, N. Constantinescu, Papillomavirus oncolytic virus. Stamatin, etc. Stefan S. Nicolau - Stefan S. Nicolau obtained in the M.
Doctor of Medicine degree at the Faculty of Medicine in Cluj, where he began this collaboration with Levaditi. Passionate, meticulous and precise his research diaries are a model in this respect. InLevaditi and Nicolau published a series of articles in which new properties of the viral agents are demonstrated: ultrafiltrability passage through the pores of a collodion membrane and the cell-mediated character of the antiviral immunity.
In a broad prospective view of the pathogenesis of viral infections, Levaditi and Nicolau underlined, beside the viral cytocidal effect, the participation of papillomavirus oncolytic virus immune response of the host in the triggering of the symptomatology. Nicolau also pioneered the concept of viral oncolysis in studies where the neurovaccinal virus was innolculated into grafted tumours. Ann Inst Pasteur37, Medical Hypotheses44, Tumours are more susceptible papillomavirus oncolytic virus viruses than normal cells and tumours act as "a sponge attracting viral replication".
This hypothesis papillomavirus oncolytic virus rediscovered by Sinkovics and Horwath in and is now in the centre of interest for many laryngeal papillomatosis emedicine companies who enlarge cancer virotherapy models". With a remarkable intuition Nicolau promoted the concept of the oncogenic potential of the viral nucleic acids. The school of professor Nicolau provided significant arguments for the involvement of viruses in the general pathology.
The Â«Stefan S. NicolauÂ» Institute of Virology, which chronologically is one of the first institutions in this speciality in Euorpe, has celebrated in the 50th anniversary of its foundation. The Institute has ith origin in the papillomavirus oncolytic virus of the Chair papillomavirus oncolytic virus Virology, which began its activity in in the framework of the Faculty of Medicine in Bucharest.
For the first time in the world, in the higher medical education, a separate discipline was devoted to the study of the ultrafiltrable infectious agenst. Afterwards, a team of papillomavirus oncolytic virus of the Academy was created, wich developedÂ into the actual Institute of Virology.
Many disciples of the school founded by prof. Nicolau distinguished themselves by significant contributions: Adelina Derevic respiratory viral infectionsElisabeta Nastac virus-cancer relationshipsElena Oprescu respirtory viral infectionsRadu Portocala biochemistry of the viral nucleic acidsDan Sarateanu ornithosesConstantin Surdan RickettsiaNicolae Cajal his succesor at the Institute and Chair of virology direction.
From to he was Director of the Stefan S. Nicolau Papillomavirus oncolytic virus of Virology. Disciple Â and collaborator of Professor Nicolau, N. Cajal published during his lifetime numerous reference studies regarding the persistent infections herpes, papillomatosis, measles ; the genetics of polioviruses and of other attenuated Â strains used in the prophylaxis of some viral diseases; the virus cancer relationships, as will as the relationships between the viral infections and the pathology of pregnancy and of the product of conception.
The scientific Â contribution of Professor Cajal is recorded in more than papers published in Romania and abroad. Inunder the editorship of Professor N.

Cajal appeared the first volume of a remarkable treatise of Medical Virology. Papillomavirus oncolytic virus sustained and developed the concept of plurietiology of viral hepatitis. On the basis of an extensive clinical Â and pathomorphological study, the authors demonstrated the existence of several other papillomavirus oncolytic virus, with the exception of the recognized A and B types. Later research on performed in various countries confirmed the conception and the priority of the Romanian authors.
InProfessor Cajal initiated the antipoliomyelitic vaccination in Romania with the Sabin vaccine and followed-up the immunization level by antibody dosages. Objects of Â concern for the elaboration andÂ improvement of vaccines werease the anti-influenza and anti-measles vaccines, and the effect of their administrtion by intranasal or intraconjunctival route was followed-up.

Radu Portocala promoted molecular virology papillomavirus oncolytic virus in the institute and authored the textbook Â«Â Les acides ribonucleiques cellulaires et virauxÂ Â» The cellular and viral ribonucleic acids Costin Eugen Cernescu Professor Costin Eugen Cernescu ascended all the steps of papillomavirus oncolytic virus didactic career and of the medical specialization from assistant and resident to senior physician and papillomavirus oncolytic virus.
