The parasite has a unique epidemiology in Middle Eastern countries where the IId subtype family of<jats:italic>Cryptosporidium parvum<\/jats:italic>dominates. However, there has been no information on<jats:italic>Cryptosporidium<\/jats:italic>species in Yemen. Thus, this study was conducted in Yemen to examine the distribution of<jats:italic>Cryptosporidium<\/jats:italic>species and subtype families. Fecal samples were collected from 335 patients who attended hospitals in Sana'a city.<jats:italic>Cryptosporidium<\/jats:italic>species were determined by PCR and sequence analysis of the 18\u00a0s rRNA gene.<jats:italic>Cryptosporidium parvum<\/jats:italic>and<jats:italic>C. hominis<\/jats:italic>subtypes were identified based on sequence analysis of the 60\u00a0kDa glycoprotein (<jats:italic>gp60<\/jats:italic>) gene. Out of 335 samples, 33 (9\u00b79%) were positive for<jats:italic>Cryptosporidium<\/jats:italic>. Of them, 97% were identified as<jats:italic>C. parvum<\/jats:italic>whilst 1 case (3%) was caused by<jats:italic>C. hominis<\/jats:italic>. All 7<jats:italic>C. parvum<\/jats:italic>isolates subtyped belonged to the IIaA15G2R1 subtype. The common occurrence of the zoonotic IIa subtype family of<jats:italic>C. parvum<\/jats:italic>highlights the potential occurrence of zoonotic transmission of cryptosporidiosis in Yemen. However, this postulation needs confirmation with future molecular epidemiological studies of cryptosporidiosis in both humans and animals in Yemen.<\/jats:p>","DOI":"10.1017\/s0031182012001953","type":"journal-article","created":{"date-parts":[[2013,2,1]],"date-time":"2013-02-01T16:49:44Z","timestamp":1359737384000},"page":"729-734","source":"Crossref","is-referenced-by-count":23,"title":["First molecular characterization of<i>Cryptosporidium<\/i>in Yemen"],"prefix":"10.1017","volume":"140","author":[{"given":"N.
