2.1.1. Domestic Pig Blood

The blood was obtained from the Bost Meat Plant in Turosn Koscielna from adult pigs of the species *Sus domestica*. Animal blood was collected directly into sterile test tubes made of unbreakable plastic with buffered sodium citrate in a ratio of 1:9 to biological material. Those test tubes were delivered to the laboratory, where individual morphotic elements of blood were immediately isolated.
