We identified the<jats:italic>Cryptosporidium<\/jats:italic>spp. in 199 positive human stool samples by PCR\u2013RFLP of the 18S rRNA and COWP gene loci. Subspecies were identified in 104 samples by sequence analysis of the 60 kDa glycoprotein (gp60) gene fragment. Overall<jats:italic>C. parvum<\/jats:italic>was identified in 80%, and<jats:italic>C. hominis<\/jats:italic>in 20% of cases. No other<jats:italic>Cryptosporidium<\/jats:italic>spp. were detected.<jats:italic>C. parvum<\/jats:italic>was by far the most common species in the rural, more sparsely populated west of Ireland and exhibited a pronounced spring peak coincident with a peak in the national cryptosporidiosis incidence rate. Our data indicated a trend towards higher proportions of<jats:italic>C. hominis<\/jats:italic>in older age groups. Ninety-nine per cent of all subtyped<jats:italic>C. parvum<\/jats:italic>isolates belonged to allele family IIa, of which allele IIaA18G3R1 was by far the most common (63%). According to a recent study by Thompson and colleagues [<jats:italic>Parasitology Research<\/jats:italic>(2007),<jats:bold>100<\/jats:bold>, 619\u2013624] this allele is also the most common in Irish cattle. Subtyping of the<jats:italic>C. hominis<\/jats:italic>isolates indicated that they belonged to a geographically widely distributed allele (IbA10G2) known to have caused several water- and foodborne outbreaks around the world. The predominance of<jats:italic>C. parvum<\/jats:italic>, its geographic and seasonal distribution and the IIaA18G3R1 subtype underlines the importance of zoonotic<jats:italic>Cryptosporidium<\/jats:italic>transmission in Ireland.<\/jats:p>","DOI":"10.1017\/s0950268808000769","type":"journal-article","created":{"date-parts":[[2008,5,12]],"date-time":"2008-05-12T14:11:07Z","timestamp":1210601467000},"page":"270-277","source":"Crossref","is-referenced-by-count":61,"title":["The prevalence of<i>Cryptosporidium<\/i>species and subtypes in human faecal samples in Ireland"],"prefix":"10.1017","volume":"137","author":[{"given":"A.","family":"ZINTL","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
