| pubmed-article:9137647 | pubmed:abstractText | Outbred suckling mice (NMRI strain) were used as hosts. They were initially inoculated with oocysts of human origin, and subsequently with parasites recovered from the mouse ileal mucosa. Cryptosporidia were counted in an aliquot of whole-ileum homogenate. Parasite load was expressed as cryptosporidia per centimeter of ileum. Serial passage of C. parvum in NMRI mouse litters led to a gradual amplification of parasite burden relative to animals initially inoculated with the human isolate. | lld:pubmed |
