transplanted and hemodialysis patients are frequently affected by parasitic diseases such as cryptosporidiosis. cryptosporidium is a parasite causing self-limited diarrhea and enteritis in healthy individuals. the presence of cryptosporidium infection was studied in three groups including 87 renal transplant patients, 103 hemodialysis patients, and 60 healthy individuals as the control group. t...

Background: Cryptosporidium spp. is one of the most important parasitic pathogen which causes acute gastroenteritis in human. This study aimed to determine and compare the contamination rates of Cryptosporidium oocysts in some common vegetables that are cultured and consumed in Koya City, Iraq. Methods: Totally, 400 vegetable samples were collected randomly from vegetable farms in Koya city du...

The purpose of this study was to investigate the occurrence of Cryptosporidium spp. and Giardia spp. in a public water-treatment system. Samples of raw and treated water were collected and concentrated using the membrane filtration technique. Direct Immunofluorescence Test was performed on the samples. DNA extraction using a commercial kit was performed and the DNA extracted was submitted to a ...

BACKGROUND Cryptosporidium spp. is a coccidian parasite infected humans and animals. Prevalence rate of Cryptosporidium spp. infection associated with is some parameters such as sampling, age, season, country and contact to domestic animals. This study aimed to determine Cryptosporidium spp. Infection in humans and some animals in rural areas of Shushtar district from Khuzestan Province, south-...

The present work was initiated to study the incidence, morphology and molecular identification of Cryptosporidium spp. infecting ducks. Incidence of Cryptosporidium spp. in ducks was 39.9 % (365 out of 915 ducks). Seasonal incidence showed that the highest rate was in winter (74.6%) while the lowest one was in autumn (7.1%). Cryptosporidium spp. oocysts were spherical to ovoid in shape with smo...

There has been an explosion of descriptions of new species of Cryptosporidium during the last two decades. This has been accompanied by confusion regarding the criteria for species designation, largely because of the lack of distinct morphologic differences and strict host specificity among Cryptosporidium spp. A review of the biologic species concept, the International Code of Zoological Nomen...

A 3 year study was conducted to evaluate mussels as bioindicators of faecal contamination in coastal ecosystems of California. Haemolymph samples from 4680 mussels (Mytilus spp.) were tested for Cryptosporidium genotypes using PCR amplification and DNA sequence analysis. Our hypotheses were that mussels collected from sites near livestock runoff or human sewage outflow would be more likely to c...

To understand the situation of water contamination with Cryptosporidium spp. and Giardia spp. in the northern region of Portugal, we have established a long-term program aimed at pinpointing the sources of surface water and environmental contamination, working with the water-supply industry. Here, we describe the results obtained with raw water samples collected in rivers of the 5 hydrographica...

There have been a few reports from Iran concerning infection by Cryptosporidium species, but they have referred particularly to infection in animals and their handlers. This study of infection in humans was carried out over a two year period in a large urban area in a cold region of western Iran. 554 stool specimens were examined with modified Ziehl - N eelson (MZN) staining for Cryptospor...
