Abstract
Cryptosporidium (C.) parvum is the most prevalent species in the middle-east
countries especially in Iraq and its zoonotic importance is not well documented.
Hence, the current work included the study of the genetic profile of
Cryptosporidium species from the fecal samples of infected cattle owners and
cattle. Two hundred stool specimens were collected from cattle owners
complaining of watery diarrhea and 100 fecal samples from diarrheic cattle in
several rural areas of Zakho district. All stool specimens were analyzed
microscopically using modified Ziehl Neelsen stain technique and genetically
using traditional PCR approach targeting 18S rRNA,
HSP70 and gp60 genes. The prevalence of Cryptosporidiosisin
humans was 70% (140/200) and among infected cattle was 62% (62/100) by using
modified Ziehl-Neelsen stain. On other hand, the molecular analysis (PCR)
identified Cryptosporidiosisin 74.5% (149/200) among human samples and
65% (65/100) among cattle samples. The similarity in the analysis of Targeting
genes presented that all isolates were identified as C. parvum which have
82–99.8 % similarity to other isolates from Iraq, China and USA. The
phylogenetic analysis based on gp60 sequences of Cryptosporidium
parvum revealed two subtypes belonging to family subtypes IIa (IIdA21G1 and
IIdA19G1). This study confirms the prevalence of C. parvum among humans
and cattle in this area. Furthermore, the C. parvum isolated from cattle
are genetically identical to those found in humans.
