Small ruminants and zoonotic cryptosporidiosis.

摘要: Sheep and goats are commonly infected with three Cryptosporidium species, including parvum, ubiquitum, xiaoi, which differ from each in prevalence, geographic distribution, public health importance. While C. parvum appears to be a dominant species small ruminants European countries, its occurrence most African, Asian, American countries appear limited. As result, zoonotic infections due contact lambs goat kids common leading frequent reports of outbreaks cryptosporidiosis on petting farms. In contrast, xiaoi is the elsewhere, mostly does not infect humans. ubiquitum another it occurs sheep at much lower frequency. Host adaptation present both consisting several subtype families different host preference. The host-adapted nature has allowed use subtyping tools tracking infection sources. This led identification differences importance epidemiology human cryptosporidiosis. These have also been used effectively linking transmission between outbreak cases suspected animals. Further studies should directly elucidating reasons for distribution major goats.
