Abstract:
:Most human cases of cryptosporidiosis are caused by Cryptosporidium parvum or Cryptosporidium hominis, but the use of molecular diagnostic methods has revealed that several other less common species or genotypes can also be involved. Here, we describe two unusual causes of cryptosporidiosis, one being the recently described species Cryptosporidium viatorum and the other Cryptosporidium chipmunk genotype I. Two Swedish patients who were infected with C. viatorum had travelled to Kenya and Guatemala, respectively, and two others had been infected with Cryptosporidium chipmunk genotype I in Sweden. None of these four patients were immunocompromised, and all four showed classical symptoms of cryptosporidiosis. We performed extensive molecular characterization, including analysis of four loci. The two C. viatorum isolates were found to differ slightly at the 70-kDa heat shock protein locus, which may indicate a local geographical variation in this species that has previously been described exclusively on the Indian subcontinent.
