Cryptosporidium parvum is an important zoonotic parasitic disease worldwide, but the molecular mechanisms of the host-parasite interaction are not fully understood. Noncoding microRNAs (miRNAs) are considered key regulators of parasitic diseases. Therefore, we used microarray, qPCR, and bioinformatic analyses to investigate the intestinal epithelial miRNA expression profile after Cryptosporidium parvum infection. Twenty miRNAs were differentially expressed after infection (four upregulated and 16 downregulated). Further analysis of the differentially expressed miRNAs revealed that many important cellular responses were triggered by Cryptosporidium parvum infection, including cell apoptosis and the inflammatory and immune responses. This study demonstrates for the first time that the miRNA expression profile of human intestinal epithelium cells is altered by C. parvum infection. This dysregulation of miRNA expression may contribute to the regulation of host biological processes in response to C. parvum

INPANKAEW, T. et al. Seroprevalence of Cryptosporidium parvum infection of dairy cows in three northern provinces of Thailand determined by enzyme-linked immunosorbent assay using recombinant antigen CpP23. Onderstepoort j. vet. res. [online]. 2009, vol.76, n.2, pp.161-165. ISSN 2219-0635.. Cryptosporidium parvum is the most frequent parasitic agent that causes diarrhoea in AIDS patients in Thailand. Cryptosporidiosis outbreaks in humans may be attributed to contamination of their drinking water from infected dairy pastures. A 23-kDa glycoprotein of C. parvum (CpP23) is a sporozoite surface protein that is geographically conserved among C. parvum isolates. This glycoprotein is a potentially useful candidate antigen for the diagnosis of cryptosporidiosis by enzyme-linked immunosorbent assay. Therefore, we investigated the seroprevalence of C. parvum infection in dairy cows in northern Thailand using an ELISA based on recombinant CpP23 antigen. Sera were randomly collected from 642 dairy cows of ...

Cryptosporidium parvum is a waterborne coccidian protozoan parasite known to infect humans, resulting in an illness known as cryptosporidiosis. The widely used USEPA method 1622 to detect Cryptosporidium is time consuming, and unable to provide the information on oocysts viability and species. In order to develop a fast detection method for viable C. parvum oocysts, a 0.2 μm pore size hollow fiber membrane and 0.45 μm pore size disc membrane were used to filter tap water. Modified Immunomagnetic separation (IMS) purification was followed, and the IMS condition was optimized to shorten the purification time. Finally, fluorescence in situ hybridization (FISH) and FITC-conjugated monoclonal antibody (FMAb) staining were combined to detect viable oocysts, and results indicated that the viable oocysts detection by FISH/FMAb can be achieved in 20 min. The total viable oocysts detection time can be shortened to less than 1.5 h without affecting oocysts recovery. © IWA Publishing 2011 ...

The apicomplexan parasites Cryptosporidium parvum and C. hominis are major etiologic agents of human cryptosporidiosis. Infection is typically self-limited in immunocompetent adults, but can cause chronic, fulminant diarrhea in immunocompromised patients, and malnutrition and stunting in children. Nitazoxanide, the current standard-of-care for cryptosporidiosis, is only partially efficacious for children and is no more effective than placebo in AIDS patients. Unfortunately, financial obstacles to drug discovery for diseases that disproportionately affect low-income countries and technical limitations associated with studies of Cryptosporidium biology both impede development of better drugs for cryptosporidiosis. Using a cell-based high-throughput screen, we queried the Medicines for Malaria Ventures (MMV) Open Access Malaria Box for activity against C. parvum. We identified 3 novel chemical series derived from the quinolin-8-ol, allopurinol-based, and 2,4-diamino-quinazoline chemical ...

There are very few molecular genetic tools available to study the apicomplexan parasite Cryptosporidium parvum. The organism is not amenable to continuous in vitro cultivation or transfection, and purification of intracellular developmental stages in sufficient numbers for most downstream molecular applications is difficult and expensive since animal hosts are required. As such, very little is known about gene regulation in C. parvum. We have clustered whole-genome gene expression profiles generated from a previous study of seven post-infection time points of 3,281 genes to identify genes that show similar expression patterns throughout the first 72 hours of in vitro epithelial cell culture. We used the algorithms MEME, AlignACE and FIRE to identify conserved, overrepresented DNA motifs in the upstream promoter region of genes with similar expression profiles. The most overrepresented motifs were E2F (5′-TGGCGCCA-3′); G-box (5′-G.GGGG-3′); a well-documented ApiAP2 binding motif (5′-TGCAT-3′)

Over the course of six months wild filth flies were collected from traps left for 7-10 days in a barn with or without a calf shedding Cryptosporidium parvum Genotype 2 oocysts in diarrheic feces. The oocysts of C. parvum transported on the flies' exoskeletons and eluted from their droplets left on visited surfaces were infectious for mice. The mean number of oocysts carried by a fly varied from 4 to 131, and the total oocyst number per collection varied from 56 to approximately 4.56 x 10(3). Fly abundance and intensity of mechanical transmission of infectious C. parvum oocysts were positively correlated, and both increased significantly when an infected calf was in the barn. Molecular data showed that the oocysts shed by infected calves were carried by flies for at least 3 weeks. Filth flies can acquire infectious C. parvum oocysts from unsanitary sites, deposit them on visited surfaces, and therefore may be involved in human or animal cryptosporidiosis.

Giardia lamblia and Cryptosporidium parvum are both waterborne pathogens associated with diarrhoea in developing countries. In a recent study based at the Aga Khan University in Karachi, 334 adults aged 16-83 years (178 Patients with chronic diarrhoea and 156 diarrhoea-free volunteers who acted as controls) were checked for infection with these parasites, using stool microscopy and/or PCR. Overall, 21 (6.3%) and 29 (8.7%) of the subjects were found positive for G. lamblia by microscopy and PCR, respectively, while the corresponding values for C. parvum were 13 (3.9%) and 14 (4.2%). Although, compared with the diarrhoea-free controls, the Patients with diarrhoea were not significantly more likely to be found infected with Giardia, either by microscopy [15 (8.4%) v. six (3.8%), P=0.085] or PCR [19 (10.7%) v. 10 (6.4%), P=0.167], they were significantly more likely to be found infected with C. parvum, both by microscopy [11 (6.2%) v. two (1.3%), P=0.024] and by PCR [12 (6.7%) v. two (1.3%), P=0.014].The 19

Microcentrifuge tubes containing 8 x 10(6) purified oocysts of Cryptosporidium parvum suspended in 400 microliters of deionized water were stored at 5 degrees C for 168 h or frozen at -10, -15, -20, and -70 degrees C for 1 h to 168 h and then thawed at room temperature (21 degrees C). Fifty microliters containing 10(6) oocysts was administered to each of five to seven neonatal BALB/c mice by gastric intubation. Segments of ileum, cecum, and colon were taken for histology from each mouse 72 or 96 h later. Freeze-thawed oocysts were considered viable and infectious only when developmental-stage C. parvum organisms were found microscopically in the tissue sections. Developmental-stage parasites were not found in tissues from any mice that received oocysts frozen at -70 degrees C for 1, 8, or 24 h. All mice that received oocysts frozen at -20 degrees C for 1, 3, and 5 h had developmental-stage C. parvum; one of 6 mice that received oocysts frozen at -20 degrees C for 8 h had a few ...

The humoral immune response is dominated by IgG1 subclass antibodies but can also include IgA and IgM antibodies. The glycosylinositol phospholipids were purified by butanol extraction of a Triton X-114-soluble fraction followed by octyl-Sepharose column chromatography and preparative high performance TLC and were ...

We report the results of molecular analysis of 39 isolates of Cryptosporidium parvum from human and bovine sources in nine human outbreaks and from bovine sources from a wide geographic distribution. All 39 isolates could be divided into either of two genotypes, on the basis of genetic polymorphism observed at the thrombospondin-related adhesion protein (TRAP-C2) locus. Genotype 1 was observed only in isolates from humans. Genotype 2, however, was seen in calf isolates and in isolates from a subset of human patients who reported direct exposure to infected cattle or consumed items thought to be contaminated with cattle feces. Furthermore, experimental infection studies showed that genotype 2 isolates were infective to mice or calves under routine laboratory conditions, whereas genotype 1 isolates were not. These results support the occurrence of two distinct transmission cycles of C. parvum in humans.

Purpose. Conventional laboratory detection methods for gastrointestinal parasites are time consuming, require considerable technical expertise and may suffer from poor analytical sensitivity. This study sought to evaluate the automated BD MAX Enteric Parasite Panel (EPP) for the detection of Cryptosporidium parvum/hominis, Entamoeba histolytica and Giardia duodenalis. Methodolgy. A total of 104 known positive samples (43 Cryptosporidium parvum/hominis and 61 G . duodenalis), 15 simulated samples (E. histolytica and other Entamoeba species) and 745 patient stool samples, submitted for enteric pathogen culture and microscopy, were inoculated into BD MAX EPP sample buffer tubes (SBTs). All specimens were blinded and tested within 7 days of SBT inoculation using the BD MAX EPP assay with results compared to those generated by microscopy. Results/Key findings. Combining the results from the known positive samples and anonymously tested patient samples, the sensitivity of the BD MAX EPP assay was 100 % for

Used alone, UV radiation does not improve the taste, odor, or clarity of water. UV light is a very effective disinfectant, although the disinfection can only occur inside the unit. There is no residual disinfection in the water to inactivate bacteria that may survive or may be introduced after the water passes by the light source. The percentage of microorganisms destroyed depends on the intensity of the UV light, the contact time, raw water quality, and proper maintenance of the equipment. If material builds up on the glass sleeve or the particle load is high, the light intensity and the effectiveness of treatment are reduced. At sufficiently high doses, all waterborne enteric pathogens are inactivated by UV radiation. The general order of microbial resistance (from least to most) and corresponding UV doses for extensive (,99.9%) inactivation are: vegetative bacteria and the protozoan parasites Cryptosporidium parvum and Giardia lamblia at low doses (1-10 mJ/cm2) and enteric viruses and ...

In 1993, almost 25% of the residents of Milwaukee, Wisconsin came down with severe stomach cramps, fever, and diarrhea. Over 100, mostly elderly or immunocompromised residents, died. The cause? The most common water-borne disease in the developed world: Cryptosporidium. Cryptosporidium parvum is one of many species of this group of apicomplexan parasites, distant relatives to those that cause malaria and toxoplasmosis. Water supplies may be tainted with the oocysts of these parasites, which are then consumed by people. In the small intestine, the parasites attach to the villi and begin to asexually divide. Eventually they will produce gametocytes - macrogametocytes are female, microgametocytes are male. These stages fuse and then produce two types of zygotes. Some have thin walls only - these serve to keep the infection going in the same host. Others, though, develop thicker walls and are released into the environment to infect new hosts. There isnt a very good treatment for those that become ...

We examined the effects of chlorine on oocyst viability, under the conditions of controlled pH and elevated calcium concentrations required for most community swimming pools. We found that fecal material may alter the Ct values (chlorine concentration in mg/L, multiplied by time in minutes) needed to disinfect swimming pools or other recreational water for Cryptosporidium parvum.

Cryptosporidium parvum (C. parvum) is ubiquitous in our environment. Humans, 152 species of mammals, fish, amphibians, reptiles, and birds can carry and spread the parasite by depositing oocysts in their faeces. Both sexual and asexual lifecycles can take place in a single host. The parasite produces oocysts which are thick-walled, nearly spherical, range in size from 4-6μm in…

The difference between the results obtained in the present study, using microscopic and molecular diagnostic techniques remains a controversial subject within the scientific community. Some researchers have reported the high sensitivity of PCR-mediated oocyst detection [15,29], whereas others have reported better results when using microscopy [9]. Several hypotheses have been considered to explain the results of the present study. Among the major hypotheses, we can cite the low parasite loads present in some samples, the non-homogeneous oocyst distribution in the fecal material and the presence of inhibitors that might have led to underestimations of the PCR results. Regarding the low parasite loads, some authors [9] mentioned that a low oocyst recovery from fecal material could yield a low percentage of positive results when using molecular techniques.. In addition to the issue of low numbers of oocysts and the PCR-mediated detection of Cryptosporidium spp., is supposed that the heterogeneous ...

We have previously reported a simple method to detect viable Cryptosporidium parvum oocysts in drinking water using the isothermic Nucleic Acid Sequence Based Amplification (NASBA) method, coupled with a rapid liposme nanovesicle (Nanozome)-based biosensor technology. This assay system is based upon the ability to immunocapture low numbers (i.e., five or more) oocysts and heat shock them to induce the production of a specific nRNA, which in turn, can be amplified by NASBA. Then, the resulting single stranded amplicons can be directly quantified by a rapid and visually detectable hybridization reaction employing a highly sensitive Nanozome-amplified lateral-flow assay. The entire assay, completed within 4-5 hours, can overcome many of the problems inherent in the current EPA Methods 1622 and 1623, particularly labor-intensity, inability to distinguish nonviable from viable oocysts, and deceasing the possibility of false positive determinations caused by misreading of immunofluorescence slides. ...

Background: Cryptosporidiosis is a pathological condition caused by infection with coccidian protozoan parasites Cryptosporidium. Cryptosporidium is one of the most common causes of childhood diarrhea in developing countries. So far, no data has been published on its prevalence among children with diarrhea in Cameroon. This study was therefore, designed to assess the prevalence and risk factors associated with Cryptosporidiosis among children within the ages 0-5 years suffering from diarrhea and being attended to at the Limbe Regional Hospital. Methods: The study was a hospital based analytical cross-sectional study involving children within the ages 0-5 years (n = 112) hospitalized or consulted in the pediatric departments of the hospital between April 2018 and May 2018. Stool specimens were processed using the modified acid-fast staining method, and microscopically examined for Cryptosporidium infection. Results: A total of 112 participants were recruited out of which 67 presented with ...

Citation: N/A Interpretive Summary: Technical Abstract: Cryptosporidium parvum is a protozoan parasite that causes intestinal infection and diarrhea in over 150 species of mammals, including humans and economically important livestock species. There are no effective vaccines or drug treatments available for this parasite. Cryptosporidium parvum has been shown to utilize a metabolic pathway not found in mammals for the synthesis of polyamines, forming agmatine as an intermediary metabolite. Thus, interference with this pathway may compromise the parasite, with minimal effects on the mammalian host. In the present study, we treated infant mice with oral doses of agmatine for 2 days before, the day of, and 5 days following, experimental infection with C. parvum. Mice treated with agmatine were significantly less infected with C. parvum than were control mice. Mice treated with agmatine only on the day of experimental infection with C. parvum were also significantly less infected than were control ...

The coccidian genera that cause disease in humans include Cryptosporidium, Cyclospora, Isospora, Sarcocystis, and Toxoplasma. What was previously called Cryptosporidium parvum and was thought to be the primary Cryptosporidium species infecting humans is now classified as two separate species, C. parvum (mammals, including humans) and Cryptosporidium hominis (primarily humans). Evidence obtained from excystation experiments indicates that the oocyst contains two sporocysts, each containing two sporozoites, a pattern which places these organisms in the coccidian genus Cyclospora. Electron microscopy (EM) confirmed the presence of characteristic organelles for coccidian organisms of the phylum Apicomplexa. Phylogenetic studies have confirmed that the microsporidia evolved from the fungi, being most closely related to the zygomycetes. Microsporidia have extremely small genomes, very similar to those seen in bacteria. A variety of serologic tests have been used to detect immunoglobulin G (IgG) and IgM

Cryptosporidium species are protozoan parasites that infect humans and a wide variety of animals. This study was aimed at identifying Cryptosporidium species and genotypes isolated from avian hosts. A total of 90 samples from 37 different species of birds were collected throughout a 3-month period from April 2008 to June 2008 in the National Zoo of Kuala Lumpur, Malaysia. Prior to molecular characterization, all samples were screened for Cryptosporidium using a modified Ziehl-Neelsen staining technique. Subsequently samples were analysed with nested-PCR targeting the partial SSU rRNA gene. Amplicons were sequenced in both directions and used for phylogenetic analysis using Neighbour-Joining and Maximum Parsimony methods. Although 9 (10) samples were positive for Cryptosporidium via microscopy, 8 (8.9) produced amplicons using nested PCR. Phylogenetic trees identified all the isolates as Cryptosporidium parvum. Although C. parvum has not been reported to cause infection in birds, and the role of ...

Sumiti Vinayak of the University of Georgia in the U.S. will develop a genetic tool to rapidly turn genes off using light in order to study the function of essential genes in the intestinal parasite Cryptosporidium and accelerate drug discovery. Cryptosporidium causes chronic diarrhea and can lead to death in young children. There is currently only one drug available and it is not effective in many patients. New drugs can be developed based on a detailed understanding of the function of essential proteins, however this has been challenging in Cryptosporidium because it is not possible to control when a protein is degraded. They will develop a construct that fuses a protein of interest to a light-inducible domain carrying a hidden degradation signal. When exposed to blue light, this signal is activated, leading to protein degradation at a selected time. They will first optimize their system in vitro using the nanoluciferase gene and C. parvum sporozoites. They will then test it on a candidate ...

CHAMPAIGN, Ill. -- Fresh from the faucet, a killer may be lurking in your glass. Cryptosporidium parvum is a parasitic protozoan that can infiltrate a city s water supply -- as happened in Milwaukee in March 1993, when more than 400,000 people were infected. With symptoms similar to food poisoning, outbreaks of cryptosporidiosis can prove deadly for individuals with immune system deficiency problems. Researchers at the University of Illinois are developing a cost-effective treatment strategy for providing drinking water free of this harmful contaminant.. Most surface-water disinfection systems in the U.S. were originally designed, or subsequently modified, to control contamination by another dangerous microbe, Giardia lamblia, said Benito Marinas, a UI professor of civil and environmental engineering. Unfortunately, the disinfectant concentration and contact time in these systems are generally inadequate for killing C. parvum.. Destroying the parasite is also complicated by the fact that, ...

Cryptosporidiosis is caused by a variety of factors and can be treated effectively with medications. The disease is caused by the ingestion of the intestinal parasite Cryptosporidium and is commonly ingested through contaminated water, food or feces.

Rapid identification of the two major species of Cryptosporidium associated with human infections, Cryptosporidium hominis and Cryptosporidium parvum, is important for investigating outbreaks of cryptosporidiosis. This study reports the development and validation of a real-time PCR TaqMan procedure for detection of Cryptosporidium species and identification of C. hominis and C. parvum in stool specimens. This procedure comprised a generic TaqMan assay targeting the 18S rRNA for sensitive detection of Cryptosporidium species, as well as two other TaqMan assays for identification of C. hominis and C. parvum. The generic Cryptosporidium species assay can be duplexed with the C. parvum-specific assay. The generic Cryptosporidium species assay was able to detect ten Cryptosporidium species and did not cross-react with a panel of ten other protozoan parasites. The generic Cryptosporidium species assay could detect 1-10 oocysts in a 300 μl stool specimen, whilst each of the species-specific TaqMan assays had

Abstract The therapeutic efficacy of pooled bovine colostrum for the control of cryptosporidiosis was investigated during murine acquired immunodeficiency syndrome in female C57B1/6 mice. Mice were infected with LP-BM5 murine leukemia retrovirus for four months and then inoculated with Cryptosporidium parvum oocysts. Persistent cryptosporidiosis was established in all retrovirus immunosuppressed mice, while control mice were refractory to infection. Parasite colonization of intestinal villi was significantly (P < 0.05) reduced in immunosuppressed animals that received dietary supplemental pooled bovine colostrum compared with to those that did not receive colostrum treatment. Similarly, shedding of oocysts in the feces of immunosuppressed animals that received dietary pooled bovine colostrum was significantly (P < 0.05) reduced compared with those that did not at 26 days post-parasite challenge. Since the nonimmune bovine colostrum contained no anti-Cryptosporidium antibodies, this suggests that

To compare the diagnostic sensitivity and specificity of seven Cryptosporidium diagnostic assays used in the UK, results from 259 stool samples from patients with acute gastrointestinal symptoms were compared against a nominated gold standard (real-time PCR and oocyst detection). Of the 152 true positives, 80 were Cryptosporidium hominis, 68 Cryptosporidium parvum, two Cryptosporidium felis, one Cryptosporidium ubiquitum and one Cryptosporidium meleagridis. The Cryptosporidium spp. diagnostic sensitivities of three Cryptosporidium and Giardia combination enzyme immunoassays (EIA) coupled with confirmation of positive reactions were 91.4-93.4 %, whilst the sensitivity of auramine phenol microscopy was 92.1 % and that of immunofluorescence microscopy (IFM) was 97.4 %, all with overlapping 95 % confidence intervals. However, IFM was significantly more sensitive (P = 0.01, paired test of proportions). The sensitivity of modified Ziehl-Neelsen microscopy was 75.4 %, significantly lower than those for the

This report aims to propose a new species of Cryptosporidium isolated from reptiles. Cryptosporidium spp. are apicomplexan parasites of a wide range of animals. Due to their biology, ecology and epidemiology these protozoa are globally distributed. The vertebrate hosts become infected through host-to-host contact or through ingestion of contaminated food or water [1, 2]. The taxonomy of Cryptosporidium has been debated and several doubts and uncertainties still exist. For a long time the only recognized species have been Cryptosporidium parvum and Cryptosporidium muris. However, numerous other isolates were present in animals but described only in the last decades [3]. The difficulties in addressing Cryptosporidium taxonomy and in delineating new species mainly rely on the inability to morphologically discriminate the biological stages and on the difficulties in establishing monospecific experimental infections [3]. With the advent of nucleic acid-based techniques and sequencing, important ...

Swimming-pool associated outbreaks of cryptosporidiosis have been frequently reported in the UK and USA. Cryptosporidium oocysts could sometimes be detected in the pool water or the filter backwash water in cases where the source of the outbreak was confirmed. The occurrence of Cryptosporidium and Giardia in swimming pools in the Netherlands was studied at five locations. The backwash water from seven pool filters (from toddler pools, hot whirlpools and recreational and learner pools with an elevated water temperature) was analysed for the presence of Cryptosporidium oocysts and Giardia cysts for a period of one year. Of the total 153 samples of filter backwash water analysed, 18 (11.8 %) were found positive for either Cryptosporidium (4.6 %), Giardia (5.9 %) or both (1.3 %). The presence of Cryptosporidium oocysts and Giardia cysts in filter backwash water indicates previous presence of these parasites in the pool water. Oocysts and cysts were detected in the water of one toddler pool and one ...

Cryptosporidiosis, resulting from infection with the protozoan parasite Cryptosporidium, is a significant opportunistic disease among HIV-infected individuals. With multiple routes of infection due to the recalcitrant nature of its infectious stage in the environment, the formulation of effective and practical control strategies for cryptosporidiosis must be based on a firm understanding of its epidemiology. Prevalence data and molecular characterization of Cryptosporidium in HIV-infected individuals is currently available from numerous countries in Africa, Asia, Europe, North America and South America, and it is clear that significant differences exist between developing and developed regions. This review highlights the current global status of Cryptosporidium infections among HIV-infected individuals, and puts forth a contextual framework for the development of integrated surveillance and control programs for cryptosporidiosis in immune compromised patients. Given that there are few specific ...

Cryptosporidiosis is a pathological condition caused by infection with coccidian protozoan parasites Cryptosporidium. Cryptosporidium is one of the most common causes of childhood diarrhea in developing countries. So far, no data has been published on its prevalence among children with diarrhea in Cameroon. This study was therefore, designed to assess the prevalence and risk factors associated with Cryptosporidiosis among children within the ages 0-5 years suffering from diarrhea and being attended to at the Limbe Regional Hospital. The study was a hospital based analytical cross-sectional study involving children within the ages 0-5 years (n = 112) hospitalized or consulted in the pediatric departments of the hospital between April 2018 and May 2018. Stool specimens were processed using the modified acid-fast staining method, and microscopically examined for Cryptosporidium infection. A total of 112 participants were recruited out of which 67 presented with diarrhea. A high prevalence 9/67 (13.40%) of

This disclosure describes, in one aspect, a method of transfecting a Cryptosporidium organism. Generally, the method includes introducing into a Cryptosporidium organism a heterologous polynucleotide comprising at least one coding region, and incubating the Cryptosporidium organism under conditions effective for the Cryptosporidium organism to express the coding region.

The diversity of Cryptosporidium at species, subtype family and subtype level in diarrhoeic children was investigated in four provinces in South Africa. A total of 442 stool samples from children ,5 years of age were collected under a large rotavirus surveillance programme and analysed by Ziehl-Neelsen acid-fast staining. Fifty-four (12.2%) were positive for Cryptosporidium, of which 25 were genotyped by polymerase chain reaction (PCR)- restriction fragment length polymorphism (RFLP) and DNA sequence analyses of the 18S rRNA gene. The majority of genotyped specimens were identified as C. hominis (76%), and a high genetic diversity was found with five different C. hominis subtype families (Ia, Ib, Id, Ie and If). Cryptosporidium parvum was found in 20% of the isolates, and three subtype families were identified (IIc, IIe and IIb), with subtype family IIc being the most common. One specimen was identified as C. meleagridis of the subtype family IIId. These results are in accordance with findings ...

Cryptosporidium parvum can cause chronic diarrhea and biliary disease in people with AIDS, resulting in significant morbidity and mortality. Highly effective antiparasitic treatment for this infection is not currently available. Paromomycin and azithromycin have some efficacy and have been used in combination in a small number of patients. However, in clinical trials of this drug combination, patients remained infected with the parasite despite improvement of their symptoms.. Improving the immune system with highly active antiretroviral therapy (HAART) has been the most effective therapy described for cryptosporidiosis (chronic infection with Cryptosporidium parvum), with over 80% of patients showing improvement. However, immune reconstitution is not possible in all patients.. Interferon gamma expression is strongly associated with control of cryptosporidiosis. IL-12 stimulates interferon gamma, and IL-12 treatment has been shown to prevent cryptosporidiosis in mice. This study will evaluate ...

Cryptosporidium hominis and Cryptosporidium parvum belong to the family of Cryptosporidiidae, unicellular parasites that cause the clinically manifested diarrhoea disease cryptosporidiosis. Species such as C. canis or C. felis seldomly infect humans. In particular, livestock such as cattle, horses and goats as well as domestic animals including dogs, cats and birds are regarded as sources and hosts of zoonotic cryptosporidia. Infections with C. hominis originate exclusively from humans themselves. First recorded as a human pathogen in 1976, cryptosporidia can currently be detected in the faeces in two to four percent of diarrhoeal patients in industrialised countries. The pathogen forms four to six micrometre (μm) large oocysts - a microscopically visible stage in the life cycle of parasitic protozoa - which are then excreted by the host. The sporozoites - the infectious developmental stage of the parasites - are then responsible for an infection. ...

Cryptosporidium is another sporozoan organism with some similarities to Toxoplasma. It was originally found in cattle with diarrhea, where it caused diarrhea in calves (predominantly 7-14 days old but sometimes up to 30 days old). Other animals and some birds (including turkeys and chickens) also can become infected. Cryptosporidium was next reported to cause diarrhea in humans who were immunocompromised, particularly those with AIDS. Then, it was discovered that Cryptosporidium-associated diarrhea occurred in nonimmunocompromised persons, most often children, with a frequency in Western countries of 0.6%-7.3% and in developing countries of 5%-30% of patients with diarrhea. This incidence is similar to that of Giardia and the major bacterial GI pathogens. Cryptosporidium infection is also found in nonimmunocompromised persons in the cattle industry, male homosexuals, travelers in various parts of the world, and in day-care centers. The organism is rarely found in humans without diarrhea. The ...

Preservation of Cryptosporidium oocysts in faecal specimens containing 75% ethanol is suitable for subsequent morphometric and molecular analysis. No significant morphologic alteration occurred after storage at ambient temperatures, ranging from 22 to 38 °C, for more than 2 years. After washing, sugar floatation and DNA extraction, a nested polymerase chain reaction targeting the small subunit ribosomal RNA gene successfully amplified Cryptosporidium DNA in all 15 isolates examined. The sensitivity of detection by polymerase chain reaction (PCR) was found to be as high as 1.25 oocysts per reaction (mean=3.01, SD=1.14). Importantly, a 2.2-kb of the complete DNA sequence of a gene encoding Cryptosporidium thrombospondin-related adhesive protein (TRAP-C1) was also consistently amplified by PCR in all isolates. The PCR-amplified product can be used as a good template for sequencing. Therefore, this simple procedure should be useful for epidemiological analysis of clinical samples from outbreaks, ...

About Cryptosporidium. Exposure to Cryptosporidium can cause cryptosporidiosis, a serious illness. Symptoms can include diarrhea, vomiting, fever and stomach pain. People with healthy immune systems recover without medical treatment. According to the Centers for Disease Control and Prevention (CDC), people with severely weakened immune systems are at risk for more serious disease. Symptoms may be more severe and could lead to serious or life-threatening illness. Examples of people with weakened immune systems include those with AIDS; those with inherited diseases that affect the immune system; and cancer and transplant patients who are taking certain immunosuppressive drugs.. The Environmental Protection Agency (EPA) has estimated that a small percentage of the population could experience gastro-intestinal illness from Cryptosporidium and advises that customers who are immunocompromised and receive their drinking water from the Bull Run Watershed consult with their healthcare professional about ...

Cryptosporidium parvum, an intracellular protozoan parasite, is a frequent cause of chronic diarrhea in HIV-infected patients, causing significant morbidity and mortality. Highly effective antiparasitic treatment for this infection is not currently available. Paromomycin and azithromycin have some efficacy and have been used in combination in a small number of patients. Immune reconstitution with highly active antiretroviral therapy appears to be the most effective therapy, but this is not possible for all patients. Interferon gamma expression is strongly associated with control of cryptosporidiosis, and IL-12 is the cytokine primarily responsible for stimulation of interferon gamma expression in vivo. It is hoped that treatment with recombinant human IL-12 can result in stimulation of an intestinal cytokine response in AIDS patients with cryptosporidiosis and that response combined with chemotherapy can lead to the elimination of detectable numbers of Cryptosporidium oocysts from the ...

PY - 2001/1/1. Y1 - 2001/1/1. N2 - Objectives: To determine the risk factors for seroconversion to two Cryptosporidium markers (15/17 kDa and 27 kDa antigens). Methods: A cohort study of HIV infected gay or bisexual men followed over one year attending a metropolitan hospital in Melbourne, Australia. Baseline and followup serum samples were obtained and questionnaires administered when individuals attended the hospital. Seroconversion to Cryptosporidium was defined as occurring when the intensity of the followup specimen was more than 10 per cent higher than that of the initial specimen. Results: Ninety-three (39 per cent) of the 236 individuals who originally participated in the 1997 serological study were recruited. Seroconversion was observed in 34 per cent (32 of 93 participants). Seroconversion ...

The efforts to cryopreserve a gastrointestinal parasite of Cryptosporidium species using traditional cryogenics have eluded scientists for decades. In this paper, a novel method of ultra-fast cooling was applied to freeze Cryptosporidium oocysts. Application of the ultra-fast freezing rate of 4000 K/s allowed for recovery of live and infectious oocysts after thawing.

The de novo biosynthesis of fatty acids takes place through the cytosolic FAS I system in mammals and fungi. In FAS I system, a single multifunctional enzyme carries out the functions of beta-ketoacyl-ACP synthase, 3-oxoacyl-ACP reductase, 3-hydroxyacyl-ACP dehydratase, Enoyl-ACP reductase and ACP-acyl transferase. This systems is also present in apicomplexans such as Toxoplasma and Cryptosporidium species and it is evident from the possessions of genes for larger multifunctional fatty acid synthase I and polyketide synthases in the gene models. The phylogenetic analysis has showed that Cryptosporidium parvum fatty acid synthase is evolutionarily related to the C. parvum polyketide synthase and also phylogenetically closer to bacterial polyketide synthases than to eukaryotic fatty acid synthases [1]. This suggests that FAS I can be a possible drug target. In contrast to seven enzymatic domains of mamalian enzyme, C. parvum enzyme contains 21 domains arranged in starter unit containing fatty acid ...

Abstract: Malaria and cryptosporidiosis, caused by apicomplexan parasites, remain major drivers of global child mortality. New drugs for the treatment of malaria and cryptosporidiosis, in particular, are of high priority; however, there are few chemically validated targets. The natural product cladosporin is active against blood- and liver-stage Plasmodium falciparum and Cryptosporidium parvum in cell-culture studies. Target deconvolution in P. falciparum has shown that cladosporin inhibits lysyl-tRNA synthetase (PfKRS1). Here, we report the identification of a series of selective inhibitors of apicomplexan KRSs. Following a biochemical screen, a small-molecule hit was identified and then optimized by using a structure-based approach, supported by structures of both PfKRS1 and C. parvum KRS (CpKRS). In vivo proof of concept was established in an SCID mouse model of malaria, after oral administration (ED90 = 1.5 mg/kg, once a day for 4 d). Furthermore, we successfully identified an opportunity ...

On 10/27/15, Dr. Greg Cuny from the University of Houston visited the Texas A&M University to give a presentation regarding his research on IMPDH Inhibitors for Cryptosporidiosis. Similar to ongoing projects in our lab, Dr. Cunys research is directed towards developing therapeutics against the cryptosporidium parvum parasite. For this particular project, Dr. Cunys is investigating the potential of the IMPDH enzyme as drug target by designing analogs to inhibit its activity. Inosine-5-monophosphate dehydrogenase (IMPDH) catalyzes the rate limiting step towards de novo biosynthesis of guanine nucleotides from inosine monophosphate (IMP) to xanthosine monophosphate (XMP) in the parasite. After Dr. Cunys seminar, we had the opportunity to visit the George Bush Library Museum to learn about the life and presidency of our 41st president.. ...

Nitazoxanide is a broad-spectrum antiparasitic and broad-spectrum antiviral drug that is used in medicine for the treatment of various helminthic, protozoal, and viral infections. It is indicated for the treatment of infection by Cryptosporidium parvum and Giardia lamblia in immunocompetent individuals and has been repurposed for the treatment of influenza. Nitazoxanide has also been shown to have in vitro antiparasitic activity and clinical treatment efficacy for infections caused by other protozoa and helminths; emerging evidence suggests that it possesses efficacy in treating a number of viral infections as well. Chemically, nitazoxanide is the prototype member of the thiazolides, a class of drugs which are synthetic nitrothiazolyl-salicylamide derivatives with antiparasitic and antiviral activity. Tizoxanide, an active metabolite of nitazoxanide in humans, is also an antiparasitic drug of the thiazolide class. Nitazoxanide is an effective first-line treatment for infection by Blastocystis ...

In May, just before one of the hottest summers on record, the U.S. Centers for Disease Control and Prevention issued a warning about diseases lurking in recreational water facilities such as swimming pools. In nine out of ten cases in which an infectious cause was identified, the culprit was the microscopic parasite Cryptosporidium.. Crypto, which commonly refers to both the parasite and the diarrheal disease it causes, cryptosporidiosis, infects humans and animals. It is a serious problem in developing countries, where it is a leading cause of life-threatening diarrhea in children under two. Swallowing one mouthful of crypto-contaminated water can cause illness, and cases reported in the U.S. are increasing.. While most people recover after a few weeks of significant gastrointestinal upset, young children, the elderly, and the immunosuppressed can face chronic infection, wasting, cognitive impairment, and even death. No vaccine exists, and the sole FDA-approved drug for crypto is, ...

Gastrointestinal (GI) tract infections are common and can be either clinical (symptomatic) or sub-clinical (without symptoms). In fact, BioHealths top practitioners report that eight out of ten patients who seek care have one or more GI infections. Some have active GI symptoms, others present with general complaints: fatigue, body pain, headaches, cognitive problems, light headedness, brain fog and/or general malaise. Currently the two most prevalent infections are Helicobacter pylori, a bacterium that primarily inhabits the stomach, esophagus and upper duodenum, and Cryptosporidium parvum, a parasite that primarily inhabits the small intestine and regularly cycles from intracellular to extracellular.. Helicobacter pylori infections are very prevalent and are often the cause of stomach ulcers, acid reflux, burping and belching and general upper GI distress as well as stomach cancer. While acute infections are often highly symptomatic, the body has amazing capability to adapt to infections that ...

Tense afirmado que o consumo de costro é beneficiosa para un humano adulto, pero isto é cuestionable porque a maioría dos seus compoñentes sofren unha dixestión no estómago maduro, incluíndo os anticorpos e todas as demais proteínas.

Molecular data for oocysts of human origin reported by different laboratories from tests with numerous markers revealed that two genotypes are dominant (Table 2). The human genotype (genotype 1) was detected in humans and in a single nonhuman primate. The cattle genotype (genotype 2) was detected in both animals and humans. Geographic variations in the repartition of C. parvum human and bovine genotypes seem to exist (Table 2). In Australia, anthroponotic organisms account for the majority of the cases ofC. parvum infection, with infections withC. parvum human genotype comprising 85% of infections (51). In the United States, the human genotype seems to be associated with the majority of isolates obtained from individuals in nonoutbreak situations. We have recently confirmed a higher occurrence of this anthroponotic genotype in the New World by analyzing isolates from Haiti (unpublished data). In contrast, the C. parvum bovine genotype seems to be dominant in Europe (Table 2). In regard to ...

The Infectious Disease Epidemiology working group at the BNITM starts a new project on Genetic determinants for the transmission of Cryptosporidium spp. among humans and animals in Africa in May 2016. The project will be funded by the German Research Foundation (DFG) within the German-African collaborations in infectiology Initiative. This program aims to investigate neglected infectious diseases in humans and animals as well as to establish research capacities in Africa and to build up inner- African research networks. Cryptosporidium is a globally distributed single-celled organism that causes persistent diarrhea and malnutrition in immunocompetent individuals as well as severe diarrhea in immunosuppressed patients. Although Cryptosporidium is one of the most common pathogens causing diarrhea in children under the age of two in Africa, a substantial number of cases are thought to remain undiagnosed. The pathogen can be found in both humans and animals. However, there has been very little ...
