Abstract

UK Cryptosporidium hominis isolates have previously shown slight PCR fragment length polymorphism at multiple loci. To further investigate transmission, we conducted a case-control study and sequenced the GP60 locus from 115 isolates. Nine subtypes were identified; IbA10G2 predominated. Having a non-IbA10G2 subtype was significantly linked to recent travel outside Europe.
