[Little known activity of the Czestochowa typhus Institute in 1943 and 1944].
In 1921 Prof. Rudolf Weigl started manufacturing on an industrial scale a typhus vaccine. Until the beginning of World War Two he organised five companies called Weigl Institute.

In November and December 1943 the plant was moved to Czestochowa into a main building in Wilsona str. and two four storey others in Jasnogórska str. Its head became a German doctor Mozer (witness test).

The plant was divided into "breeding", "preparatory" and "liofilisation" sections. "The breeding" was for feeders and breeding lice. Cages containing about 30,000 lice were fastened to voluntary feeders for each feeding. Next "loaders" covered a so-called key board with 20 insects and infectors introduced and pressurised solution containing live rickets into a louse intestine. After a six or seven day passage, lice ware dried and their intestines prepared to produce liofilizeate all the staff and their families were inoculated. ...
