Cryptosporidium spp. identified in the different age categories of Swedish pigs sampled in the study. The figure shows the occurrence of Cryptosporidium spp. in each age category of the sampled pigs. It also shows what species of Cryptosporidium that were identified using PCR and sequencing of the 18S rRNA gene and the 28S rRNA gene. Piglets 0–5 weeks old (n = 48), growers 6–12 weeks old (n = 57), fatteners 13–24 weeks old (n = 67) and adults (n = 50). Species determination was not possible for one sample retrieved from piglets and is referred to as unknown
