Cryptosporidium species are one of the most common causes of gastrointestinal infection in humans around the world. This study has aimed to investigate the hyper variable region of the 18S rRNA gene in Cryptosporidium for exact parasite identification .   DNA was extracted from 26 fecal samples from which initially Cryptosporidium oocysts were identified by Ziehl-Neelsen acid-fast , Auramine ...

Ultrasound in a liquid phase cause mass and heat transfer across the liquid through cavitational processes which act as nanoreactors to generate unstable mechanical equilibrium. The effect of 1 MHz ultrasound on the inactivation of Cryptosporidium parvum was investigated. Continuous irradiation of ultrasound (20 min) increased temperature due to cavitational phenomena. Ultrasound irradiation of...

aim : the aim of the present study was to determine the species and genotypes of cryptosporidium spp. among children with diarrhea by pcr- rflp using the trap-c2 gene. background : cryptosporidium is a globally distributed protozoan parasite and one of the most common causes of infection and diarrhea in humans. patients and methods : four hundred and sixty nine stool samples were collected from...

The U.S. Environmental Protection Agency has recommended the use of aerobic spores as an indicator for Cryptosporidium oocysts when determining groundwater under the direct influence of surface water. Surface properties, interaction energies, transport, retention, and release behavior of B. subtilis spores were measured over a range of physicochemical conditions, and compared with reported info...

Although pigs are commonly infected with Cryptosporidium spp. and Giardia duodenalis, including potentially zoonotic species or genotypes, little is known about age-related infection levels, seasonal differences and genetic variation in naturally infected pigs raised in organic management systems. Therefore, the current study was conducted to assess seasonal and age-related variations in preval...

The zoonotic potential of Cryptosporidium was studied in one of the most densely populated provinces of Egypt regarding livestock and people. In a representative survey, faecal samples from cattle, buffalo and stool samples from diarrhoeic children (<10 years) were investigated. Parameters assumed to be related to cryptosporidiosis were recorded for animals and children. Animal samples (804) we...

Summary Cryptosporidiosis is a disease caused by the protozoan of the genus cryptosporidium and is characterized by gastroenteritis and respiratory symptoms in humans. In an investigation on 140 human faecal samples from urummie town of west Azarbyejan area, the role of cryptosporidium in causing diarrhea in adults and children has been demonstrated and the results discussed.

One hundred and thirty-three loose or diarrhoeic stool specimens from patients admitted at Kenyatta National Hospital were examined for cryptosporidiosis. Oocysts were detected in 5(3.8%) of the total in which Cryptosporidium was the sole pathogenic agent. In addition to Cryptosporidium, other pathogens isolated included bacteria, protozoa and helminths. We therefore report that Cryptosporidium...

Oocysts of Cryptosporidium spp. were detected and differentiated by a modular arranged gene amplification procedure in various samples, mostly human stool, feces of herpetotaxa, and water, in different locations of South and Eastern Austria. Cryptosporidium parvum was found in stool samples of immunocompromised persons, in reptile feces, and in water samples. The presence of Cryptosporidium in ...

Swimming in surface water bodies (e.g., lakes, rivers) can expose the human body to substantial risk of infection by Cryptosporidium. These findings are from a one-year investigation on the occurrence and distribution of the protozoan parasite Cryptosporidium in Yunlong Lake, Xuzhou, China. Cryptosporidium oocysts were detected by immunofluorescence microscopy. From January to November of 2015,...
