Cryptosporidium Suis N. Sp. (Apicomplexa: Cryptosporidiidae) in Pigs (Sus Scrofa)

Abstract

Sources of parasite isolatesIsolates were obtained from Cryptosporidium-positive fecal samples from 3-to 5-wk-old pigs (see Table I). Deoxyribonucleic acid extraction, polymerase chain reaction, and sequence analysesOocysts were purified, and deoxyribonucleic acid (DNA) was extract-

The prevalence and molecular characterisation of Cryptosporidium spp. in small ruminants in Zambia

“…In five lambs and in the goat kid sample C. parvum (genotype 2) was identified, based on a high homology (>96%) with previously published sequences, both for the 18SrRNA gene (Ryan et al, 2003) and for the HSP-70 gene (Sulaiman et al, 2000;Ryan et al, 2003). In one lamb the pig genotype of C. parvum or Cryptosporidium suis (Ryan et al, 2004) was identified (homology > 97%). Although there is little information on the genotypes found in sheep and goats, both C. parvum (Chalmers et al, 2002) and C. suis (Ryan et al, 2005) have previously been reported in sheep.…”

A New Species of Cryptosporidium (Apicomplexa: Cryptosporidiidae) from Eastern Grey Kangaroos (Macropus giganteus)

“…obs.). Marsupial genotype II has been characterized at 4 loci, the 18S rRNA, internal transcribed spacer 1 (ITS1), Cryptosporidium oocyst wall protein (COWP), and HSP70 loci, and each has confirmed the genetic distinctness of marsupial genotype II from described Cryptosporidium species and genotypes (Power et al, 2004).…”

“…There are currently 16 species of Cryptosporidium considered as valid; C. serpentis and C. varanii (syn. C. saurophilum) in reptiles; C. molnari and C. scophthalmi in fish; C. baileyi and C. galli in birds; and C. meleagridis in birds and humans; C. suis in pigs; C. muris and C. wrairi in rodents; C. bovis and C. andersoni in cattle; C. felis in cats; C. canis in dogs; C. hominis in humans; and C. parvum in multiple mammalian species, including humans (Fayer et al, 2000(Fayer et al, , 2001Alvarez-Pellitero and Sitja-Bobadilla, 2002;Morgan-Ryan et al, 2002;Ryan et al, 2003Ryan et al, , 2004Alvarez-Pellitero et al, 2004).…”

“…of Australian marsupials have identified 2 host-adapted genotypes (Morgan et al, 1997;Power et al, 2004). The marsupial genotype I (C. fayeri n.…”

“…Cryptosporidium fayeri has since been characterized at 6 loci and described in a red kangaroo (M. rufous), eastern grey kangaroos (M. giganteus), a western barred bandicoot (Perameles bougainville), and a yellow footed rock wallaby (Petrogale xanthopus) (Morgan, Deplazes et al, 1999;Morgan, Monis et al, 1999;Xiao et al, 1999;Sulaiman et al, 2000;Power et al, 2003Power et al, , 2004. More recently, the Cryptosporidium marsupial ge-notype II was described from eastern grey kangaroos (Power et al, 2004). Marsupial genotype II has since been identified in a swamp wallaby (Wallabia bicolor), red kangaroos, and western grey kangaroos (U.…”
