The gene product 60 (gp60) of bacteriophage T4 is synthesized as a single polypeptide chain from a discontinuous reading frame as a result of bypassing of a non-coding mRNA region of 50 nucleotides by the ribosome. To identify the minimum set of signals required for bypassing, we recapitulated efficient translational bypassing in an in vitro reconstituted translation system from Escherichia col...
background : cryptosporidium, an intracellular protozean parasite, is among the major causative agents of gastroenteritis disorders in humans and also causing water-borne and food-borne outbreaks of diarrheal diseases. this study investigated subtypes of cryptosporidium in patients with gastrointestinal complaints in tehran, iran. methods: a total of 1685 fecal samples were collected from patie...
Cryptosporidium ubiquitum is an emerging zoonotic pathogen. In the past, it was not possible to identify an association between cases of human and animal infection. We conducted a genomic survey of the species, developed a subtyping tool targeting the 60-kDa glycoprotein (gp60) gene, and identified 6 subtype families (XIIa-XIIf) of C. ubiquitum. Host adaptation was apparent at the gp60 locus; s...
introduction: cryptosporidium is an apicomplexa parasite that infects humans and a wide range of domestic and wild animals. however, the sub-genotypes of the species infecting animals in iran are unclear. the aim of the present study isto identify dna fingerprinting of bovine cryptosporidium in qazvin province using sequences of gp60 gene. materials and methods : in this study we investigated...
Few studies have examined the molecular epidemiology of cryptosporidiosis in developing countries. In this study, DNA of 69 microscopy-positive human fecal samples collected from Malawi were examined by multilocus genetic analyses. From 43, 27 and 28 of the samples, the SSU rRNA, 70 kDa heat shock protein (HSP70) and 60 kDa glycoprotein (GP60) genes, respectively, were successfully PCR-amplifie...
Cryptosporidium viatorum is a globally distributed pathogenic species of Cryptosporidium that has only ever been recorded from humans, until now. For the first time, we molecularly characterised a novel subtype of C. viatorum (subtype XVbA2G1) from the endemic Australian swamp rat (Rattus lutreolus) using the small subunit of nuclear ribosomal RNA (SSU) gene and then subtyped it using the 60-ki...
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 made ...
Cryptosporidium is an obligate intracellular protozoan parasite infecting a wide range of hosts. The current study investigated the genetic profile of Cryptosporidium species in calves in Liverpool, England. Fifty-two calve fecal samples were collected from a farm and initially screened by Auramine phenol, modified Ziehl-Neelsen and ELISA. PCR analysis of 18S rRNA gene was carried out for the p...
BACKGROUND & OBJECTIVES Human cryptosporidiosis is endemic worldwide, and at least eight species have been reported in humans; the most common being Cryptosporidium hominis and C. parvum. Detailed understanding of the epidemiology of Cryptosporidium is increasingly facilitated using standardized universal technique for species differentiation and subtyping. In this study micro- and minisatellit...
