The 2nd International Weigl Conference
"MICROBIOLOGY IN THE XXI CENTURY"

In memory of Professor Rudolf Stefan Weigl (1883-1957)

Warsaw Life Sciences University - SGGW,
Warszawa, Poland: 24-26 September 2007

Ladies and Gentlemen,
Dear Colleagues,

We have a great pleasure to invite you to the exciting joint initiative, the 2nd Polish-Ukrainian Weigl Conference. This meeting is jointly organized by Polish and Ukrainian microbiologists with financial support of the Polish Academy of Sciences and Warsaw Agricultural University-SGGW.

We truly believed that the 2nd Weigl Conference will create an opportunities to establish scientific network in the area of microbiology and will build fruitful collaborative relationships between microbiologists from both countries .

Professor Rudolf S.Weigl (1883-1957) was a famous microbiologist. He worked on rickettsioses, some of the oldest infectious diseases known to the man. Since the ancient times they were responsible for large outbreaks of plaguelike illness. Genus Rickettsia includes some of the most highly virulent bacteria known. During Weigls. days it was divided into the typhus and spotted fever groups. Currently, this genus contains 21 species with several agents of uncertain taxonomy. Rickettsia prowazekii is the agent of epidemic typhus, a louse-born disease of humans worldwide. Every disaster, and war is the worst one, brings the threat of typhus epidemics .

Professor R.S.Weigl is world known not only for his achievements in microbiology but also for the first effective vaccine against epidemic typhus, he had developed in late thirties of XX century. It was a killed vaccine prepared on lice. The manufacturing procedure included feeding of lice with human blood. In a wartime many people, among them academic workers, were employed as lice feeders in Weigl Institute. Having a proof of employment lice feeders were safe from street roundups, the terrifying reality in Lvov during German occupation. Thus Professor Weigl enormous help to the protection of humans life was not only due directly to his vaccine. He should never be forgotten.

Professor R.S.Weigl.s contribution to biomedicine was profound and remarkable - he was considered as a candidate to the Nobel Prize in physiology and medicine

We invite you to share in the science and visit Warsaw, the capital of Poland .
