A louse-feeder (Polish: karmiciel wszy) was a job in interwar and Nazi-occupied Poland, at the Lviv Institute for Study of Typhus and Virology and the associated Institute in Kraków, Poland. Louse-feeders were human sources of blood for lice infected with typhus, which were then used to research possible vaccines against the disease.
