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...

Four species of Cryptosporidium are routinely found in cattle: Cryptosporidium parvum, Cryptosporidium bovis, Cryptosporidium ryanae, and Cryptosporidium andersoni. It is important to determine the species of Cryptosporidium in infected cattle because C. parvum is the only serious pathogen for humans as well as cattle. Identification of Cryptosporidium species and genotypes currently relies on ...

Cryptosporidiosis, a diarrheal disease usually caused by Cryptosporidium parvum or Cryptosporidium hominis in humans, can result in fulminant diarrhea and death in AIDS patients and chronic infection and stunting in children. Nitazoxanide, the current standard of care, has limited efficacy in children and is no more effective than placebo in patients with advanced AIDS. Unfortunately, the lack ...

Chamelea gallina clams collected from the mouths of rivers along the Adriatic Sea (central Italy) were found to harbor Cryptosporidium parvum (genotype 2), which is the lineage involved in zoonotic transmission. The clams were collected from the mouths of rivers near whose banks ruminants are brought to graze. This paper reports the environmental spread of C. parvum in Italy and highlights the ...

A total of 256 fecal specimens were randomly collected from farmed poultry in Germany and screened for the presence of Cryptosporidium spp. by PCR and further characterized by direct automated DNA sequencing. Using a nested PCR amplifying approximately 830 bp 18S rDNA fragment, 7.03% (n = 18) of the samples were Cryptosporidium-positive. In detail, Cryptosporidium was detected in 9.3% (8/86) of...

In Japan, only a few rivers have been inspected for Cryptosporidium parvum contamination, and the methods used had low sensitivity. In 1998 and 1999, we used a method with higher sensitivity to examine all large rivers used as sources of water supply in one prefecture (which we divided into four areas) in western Japan for Cryptosporidium oocysts. One sample was collected at each of 156 sites a...

objective :cryptosporidiosis is one of the most important parasitic infections in iran which causes diarrhea in humans and animals. the identification of the cryptosporidium species among humans is necessary. this study aims to identify species of cryptosporidium isolated from patients that referred to three hospitals in tehran based on the 18s rrna gene by nested pcr-rflp assay. ‎methods :in t...

Aim Present hospital based study was carried out at our tertiary care centre with an aim to study the distribution of Cryptosporidium species subtypes in patients with complaints of diarrhea. Background Cryptosporidium species are one of the important causative agents of parasitic diarrhea, amongst which Cryptosporidium hominis (C.hominis) and Cryptosporidium parvum (C.parvum) are the two maj...
