background: cryptosporidium is a worldwide protozoan parasite and one of the most common causes of infection and diarrhea in humans and cattle. the aim of the present study was determina­tion of subtypes of cryptosporidium among children with diarrhea in tehran by se­quence analysis of the highly polymorphic 60-kda glycoprotein ( gp60 ) gene. methods: fecal samples were collected from 794 diarr...

The genotyping of numerous isolates of Cryptosporidium parasites has led to the definition of new species and a better understanding of the epidemiology of cryptosporidiosis. A single-locus genotyping method based on the partial sequence of a polymorphic sporozoite surface glycoprotein gene (GP60) has been favored by many for surveying Cryptosporidium parvum and C. hominis populations. Since ge...

Cryptosporidium meleagridis is a common cause of cryptosporidiosis in avian hosts and the third most common species involved in human cryptosporidiosis. Sequencing of the highly polymorphic 60-kDa glycoprotein (gp60) gene is a frequently used tool for investigation of the genetic diversity and transmission dynamics of Cryptosporidium. However, few studies have included gp60 sequencing of C. mel...

background: cryptosporidium is an intestinal protozean parasite causing water­borne and foodborne outbreaks of diarrheal diseases. the present study was per­formed in order to find prevalence and subtypes of cryptosporidium among children with diarrhea in gonbad kavoos city, northern iran. methods: diarrheic samples were collected from 547 children. the initial parasitologi­cal diagnosis was ma...

We tested the hypothesis that the albumin-docking protein gp60, which is localized in caveolae, couples to the heterotrimeric GTP binding protein G(i), and thereby activates plasmalemmal vesicle formation and the directed migration of vesicles in endothelial cells (ECs). We used the water-soluble styryl pyridinium dye N-(3-triethylaminopropyl)-4-(p-dibutylaminostyryl) pyridinium dibromide (FM 1...

The 60-kDa endothelial cell surface albumin-binding glycoprotein (gp60) is postulated to be a docking site for albumin that mediates the uptake of albumin and its transport in cultured microvessel endothelial cells. In the present study, we used an isolated Krebs-perfused rat lung preparation to address the in vivo role of gp60 in mediating albumin uptake and transport. Addition of primary anti...

The purpose of this study was to investigate the occurrence Cryptosporidium infection and potential for transmission spp. between animals humans in northern Vietnam. A total 2715 samples (2120 human diarrheal samples, 471 non-diarrheal 124 animal stool samples) were collected through our community survey an agricultural area. All tested by direct immunofluorescence assay (DFA) using a fluoresce...

The United States has experienced a substantial increase in the reported incidence of cryptosporidiosis since 2005. Accompanying this is the emergence of a new subtype of Cryptosporidium hominis based on variation at the 60-kDa glycoprotein (gp60) locus, IaA28R4, which has become a frequently identified subtype in both sporadic and outbreak-related cases. In this study, using multilocus sequenc...

Albumin-binding proteins identified in vascular endothelial cells have been postulated to contribute to the transport of albumin via a process involving transcytosis. In the present study, we have purified and characterized a 57- to 60-kDa (gp60) putative albumin-binding protein from bovine pulmonary microvessel endothelial cells. The endothelial cell membranes were isolated from cultured cells...

In this study, a method for expressing Cryptosporidium hominis GP60 glycoprotein in Escherichia coli for production of polyclonal anti-GP60 IgY in chickens was developed aiming future studies concerning the diagnosis, prevention and treatment of cryptosporidiosis. The full-length nucleotide sequence of the C. hominis gp60 gene was codon-optimized for expression in E. coli and was synthesized in...
