Introduction/Overview. Epidemiology. Microsporidia are obligate, intracellular, spore-forming organisms that primarily cause moderate to severe diarrhea. They are ubiquitous and infect most animal species. They are classified as fungi and defined by their unique single polar tube that coils around the interior of the spore.1 Many microsporidia have been reported as pathogens in humans, but Enterocytozoon bieneusi and Encephalitozoon intestinalis are the most common microsporidia that cause infection in HIV-infected patients. Other microsporidia, such as Encephalitozoon cuniculi, Encephalitozoon hellem, Trachipleistophora hominis, Trachipleistophora anthropophthera, Pleistophora spp., Pleistophora ronneeafiei, Vittaforma (Nosema) corneae, Mycobacterium africanum, Mycobacterium ceylonensis, Nosema ocularum, Tubulinosema acridophagus, Anncaliia (syns Brachiola/Nosema) connori, Anncaliia (syn Brachiola) vesicularum, and Anncaliia (syns Brachiola/Nosema) algerae also have been implicated in human ...

Microsporidia are obligate intracellular parasites that infect eukaryotic cells and have emerged as major opportunistic human pathogens. Due to the difficulties in definitive laboratory diagnosis and insufficient knowledge, ocular microsporidiosis is infrequently reported in India. To improve diagnostic facilities, we have developed a novel duplex PCR (dPCR) for the simultaneous identification of both genera and species of isolates with microsporidian aetiology that cause keratitis. The material scraped from the corneas of 12 clinically diagnosed microsporidial keratitis patients was subjected to routine microbiological examinations and molecular diagnosis using a novel dPCR that targeted the small-subunit rRNA gene (SSU-rRNA) of microsporidia and Vittaforma corneae using genus- and species-specific primers. Of the 12 corneal scrapes, 6 showed positive results in smears, while dPCR provided positive amplification with both pan-microsporidial and V. corneae species-specific primers for 9 corneal scrapes.

Microsporidia comprise a phylum of obligate intracellular pathogens related to fungi that infect virtually all animals. Recently, the nematode Caenorhabditis elegans has been developed as a convenient model for studying microsporidia infection in a whole-animal host through the identification and characterization of a natural microsporidian pathogen of this commonly studied laboratory organism. The C. elegans natural microsporidian pathogen is named Nematocida parisii, and it causes a lethal intestinal infection in C. elegans. Comparison of the genomes of N. parisii and its closely related species Nematocida sp. 1, together with the genomes of other microsporidian species, has provided insight into the evolutionary events that led to the emergence of the large, specialized microsporidia phylum. Cell biology studies of N. parisii infection in C. elegans have shown how N. parisii restructures host intestinal cells and, in particular, how it hijacks host exocytosis for nonlytic exit to facilitate

The microsporidium Pseudoloma neurophilia was initially reported to infect the central nervous system of zebrafish causing lordosis and eventually death. Subsequently, muscle tissue infections were also identified. To understand the infection process, development, and ultrastructural pathology of this microsporidium, larval and adult zebrafish were fed P. neurophilia spores. Spores were detected in the larval fish digestive tract 3-h postexposure (PE). By 4.5-d PE, developing parasite stages were identified in muscle tissue. Wet preparations of larvae collected at 8-d PE showed aggregates of spores in the spinal cord adjacent to the notochord. All parasite stages, including spores, were present in the musculature of larval fish 8-d PE. Adult zebrafish sacrificed 45-d PE had fully developed infections in nerves. Ultrastructural study of the developmental cycle of P. neurophilia revealed that proliferative stages undergo karyokinesis, producing tetranucleate stages that then divide into ...

0023] FIG. 1 is a flow diagram for a method 10 of designing polymerase chain reaction (PCR) assays according to an embodiment of the invention. As shown in FIG. 1, the method 10 is initiated at step 12. At step 14, the PCR platform and chemistry is chosen. The choice of real-time PCR chemistry is an important consideration for design, functionality, cost, and market reasons. Based upon extensive customer interviews with clinical laboratories it has been determined that the Roche LIGHTCYCLER® 1.5/2.0 is the most common platform found in clinical laboratories. The LIGHTCYCLERs® excitation lamp falls in the blue range, necessitating the use of FRET (Fluorescent Resonant Energy Transfer) to expand the number of applicable fluorophores, and thus the number of usable detection channels. Additionally, FRET probes afford the ability to perform melt curve analysis, which is crucial in differentiating the two microsporidial targets of focus. The use of hybridization FRET-based probes also provides a ...

Monaghans research interests are divided between the laboratory and lecture hall. In the lab, her primary focus is developing economically and medically relevant cell lines and developing in vitro models for the study of microsporidian parasites.. An economically relevant project that Monaghan is pursuing is the development of a honey bee cell line. This work is, in part, the impetus for the creation of the Laurier Community Apiary, of which Monaghan is a co-founder.. Monaghans pedagogical interests include developing accessible university science programming for the visually impaired, and utilizing knowledge of memory formation to design lectures for optimal student recall. In addition to this, Monaghan is dedicated to the development of evidence based strategies for successful knowledge acquisition of large volumes of information, such as those in anatomical and physiological sciences. The ultimate goal is then for students to use these knowledge bases as foundations for higher order ...

Fungi are common in all environments and are often associated with decomposition of dead material. This is true also in fish, where fungus can grow after some other pathogen has injured or killed the host. Fish with fungal infections are a sign of unhealthy conditions or high levels of some other pathogen, that is causing inuries to the fish skin or scales. Several other groups of organisms (microsporidians, dermocystidium) are listed here under Fungi, though their exact classifications are presently being researched. ...

Electron microscopy (EM) is a highly specialized service offered by only a few laboratories in the US, including the MSU VDL. It allows the pathologist to examine the ultrastructure of cells and pathogens at magnifications up to 450,000 fold or more.. EM is commonly used to identify pathogens (especially novel ones) such as viruses, bacteria, fungi, parasites, and microsporidia. EM also helps to identify and characterize neoplastic cells and define cellular degenerative processes (particularly neurologic and renal diseases). For instance, many glomerulopathies cannot be identified without the benefit of EM. Samples can be submitted formalin fixed; however, we prefer to work with glutaraldehyde if especially high-quality images are needed. Small samples (,2-3 mm in diameter) are ideal, but larger samples (up to 3 cm) may be submitted and they will be trimmed in our laboratory. We can also work with previously paraffin-embedded tissue at an additional cost; however, diagnostic success may be ...

N2 - Microsporidia are opportunistic intracellular pathogens that can infect a wide variety of hosts ranging from invertebrates to vertebrates. During invasion, the microsporidian polar tube pushes into the host cell, creating a protective microenvironment, the invasion synapse, into which the sporoplasm extrudes. Within the synapse, the sporoplasm then invades the host cell, forming a parasitophorous vacuole (PV). Using a proteomic approach, we identified Encephalitozoon hellem sporoplasm surface protein 1 (EhSSP1), which localized to the surface of extruded sporoplasms. EhSSP1 was also found to interact with polar tube protein 4 (PTP4). Recombinant ...

Coloured transmission electron micrograph (TEM) of Enterocytozoon bieneusi - microsporidial intestinal infection. Shown are spores in a degenerating enterocyte (human intestinal lumen). Enterocytozoon bieneusi, commonly known as microsporidia, is a unicellular, parasitic fungus. The microsporidia life cycle includes a proliferative merogonic stage, followed by a sporogonic stage resulting in small, infective spores, that are used in the infection mode. The spores contain a long, coiled polar tube, which distinguishes them from all other organisms and has a crucial role in host cell invasion. It infects intestinal epithelial cells and is considered an intracellular parasite. It can be a secondary infection to AIDS/HIV.

Weevils Wobble When you go through all the trouble of importing non-native insects into your state as a biological control, you want to be sure theyre doing their job. Thats why researchers were relieved to discover whats been behind the decline in effectiveness of two South American weevil species that were introduced to control burgeoning populations of water hyacinth (Eichhornia crassipes) in Florida. According to this report in Agricultural Research magazine, the culprit is a strain of microsporidia that is infecting the weevils (Neochetina eichhorniae and N. bruchi), causing loss of life and a major decrease in reproductive rates. Now that scientists know whats killing the weevils, they are looking into ways to control the microsporidia, including cold treatments and drugs. Microsporidia themselves are sometimes employed as biocontrol agents ...

New study in Nature - Scientific Reports finds strong evidence for pesticide + pathogen hypothesis as key explanation for bee disorders.. ABSTRACT: In ecosystems, a variety of biological, chemical and physical stressors may act in combination to induce illness in populations of living organisms. While recent surveys reported that parasite-insecticide interactions can synergistically and negatively affect honeybee survival, the importance of sequence in exposure to stressors has hardly received any attention. In this work, Western honeybees (Apis mellifera) were sequentially or simultaneously infected by the microsporidian parasite Nosema ceranae and chronically exposed to a sublethal dose of the insecticide fipronil, respectively chosen as biological and chemical stressors. Interestingly, every combination tested led to a synergistic effect on honeybee survival, with the most significant impacts when stressors were applied at the emergence of honeybees. Our study presents significant outcomes on ...

According to the Pittsburgh Post-Gazette, a Pennsylvania man and his wife have filed a lawsuit against an amusement park alleging that a water ride at the park caused the man to contract a painful, eye-eating parasite.. The incident occurred while the couple was on the Raging Rapids white-water rafting ride at Kennywood Park, located outside of Pittsburgh, during the summer. Towards the end of the ride, Robert Trostle says he was splashed with water that entered his left eye. In the days that followed, Trostle experienced inflammation, photosensitivity, itchiness, and pain in his eye.. Later that week, Trostle was diagnosed with acute conjunctivitis; however, his symptoms did not improve and continued to grow in severity. Following another doctors visit, the man was diagnosed with microsporidia keratitis. This infection eats away at the cornea, or the outer dome of the eye, and requires painful surgery to remove.. Trostle underwent surgery to remove the parasite from his eye, but complete ...

A previously unknown microsporidian parasite that severely degrades muscle of yellow perch (Perca flavescens) from lakes in Minnesota, Wisconsin, and Lake Ontario was identified as belonging to the genus Heterosporis. This parasite is characterized by pyriform-shaped spores that are contained in sporophorocysts. In the wild, yellow perch, burbot (Lota lota), mottled sculpin (Cottus bairdi), trout-perch (Percopsis omiscomaycus), pumpkinseed (Lepomis gibbosus), northern pike (Esox lucius), walleye (Sander vitreus) and rock bass (Ambloplites rupestris) harbor Heterosporis naturally, but laboratory studies showed that 12 other fish species are susceptible to infection. In laboratory trials, smallmouth bass (Micropterus dolomieui) consumed significantly more fathead minnows infected with Heterosporis sp. than uninfected. Microscopically, Heterosporis sp. infection can be detected in the muscle of fish two weeks after exposure, and visually identified after seven weeks. To confirm infection, a PCR ...

Encephalitozoon cuniculi is a eukaryotic organism belonging to the phylum Microsporidia, in the kingdom Fungi. An obligate intracellular parasite, E. cuniculi occurs in laboratory mice and rabbits, monkeys, dogs, rats, birds, guinea pigs, and other mammals including humans. At various early times it was thought it was the cause of rabies and polio. This parasite may be transmitted in body exudates or transplacentally. Although damages are minimal, an infection can be fatal, especially in immunocompromised individuals such as AIDS patients. The infective form of microsporidia (E. cuniculi) is a resistant spore which can survive for a long time in the environment. The spore extrudes its polar tubule and infects the host cell. The spore injects the infective sporoplasm into the eukaryotic host cell through the polar tubule. Inside the cell, the sporoplasm undergoes extensive multiplication. This multiplication occurs either by merogony (binary fission) or schizogony (multiple fission). ...

Chemotherapy can cause immunosuppression, which may trigger latent intestinal parasitic infections in stools to emerge. This study investigated whether intestinal parasites can emerge as opportunistic infections in breast and colorectal cancer patients (n=46 and n=15, respectively) undergoing chemotherapy treatment. Breast cancer patients were receiving a 5-fluorouracil/epirubicin/cyclophosphamide (FEC) regimen (6 chemotherapy cycles), and colorectal cancer patients were receiving either an oxaliplatin/5-fluorouracil/folinic acid (FOLFOX) regimen (12 cycles) or a 5-fluorouracil/folinic acid (Mayo) regimen (6 cycles). Patients had Blastocystis hominis and microsporidia infections that were only present during the intermediate chemotherapy cycles. Thus, cancer patients undergoing chemotherapy should be screened repeatedly for intestinal parasites, namely B. hominis and microsporidia, as they may reduce the efficacy of chemotherapy treatments.. ...

Several species of bumble bees are declining in the United States; these declining populations often show higher prevalence of Nosema bombi, a microsporidian pathogen. To date, surveys of bumble bee pathogens in the United States have only been conducted on workers and males, yet the health of a population is ultimately dependent on the success of colony-founding queens. We conducted a molecular-diagnostic survey of the prevalence of N. bombi and trypanosomatids, such as Crithidia bombi, in six species of spring queens (n = 142) collected in 2011 and 2013 at three sites in central Kansas. Nosema bombi was found in 27% of Bombus pensylvanicus and 13% of B. auricomus but was not found in the other species sampled. Trypanosomatids were only found in B. pensylvanicus (9%) during the May 2013 sampling period.

The microsporidian Encephalitozoon cuniculi possesses one of the most reduced and compacted eukaryotic genomes. Reduction in this intracellular parasite has affected major cellular machinery, including the loss of over fifty core spliceosomal components compared to S. cerevisiae. To identify expression changes throughout the parasites life cycle and also to assess splicing in the context of this reduced system, we examined the transcriptome of E. cuniculi using Illumina RNA-seq. We observed that nearly all genes are expressed at three post-infection time-points examined. A large fraction of genes are differentially expressed between the first and second (37.7%) and first and third (43.8%) time-points, while only four genes are differentially expressed between the latter two. Levels of intron splicing are very low, with 81% of junctions spliced at levels below 50%. This is dramatically lower than splicing levels found in two other fungal species examined. We also describe the first case of alternative

Given consistent reports of severe wasting and malnutrition in HIV-positive adults with microsporidiosis, it is conceivable that E. bieneusi infection early in life may result in malnutrition. Two cross-sectional studies attempted to correlate microsporidiosis with poor anthropometric status but did not find a significant association (7,12). However, the dichotomous method used for these assessments is sensitive to the choice of cut-off values. Although children who fall ,2 SDs below the reference growth curves are conventionally categorized as malnourished, this cut-off does not denote a biologically meaningful distinction between healthy and malnourished children.. Using regression analysis, we present evidence that microsporidiosis may be associated with growth faltering in children in Uganda. In this approach, anthropometric data were treated as continuous variables, thus avoiding arbitrary categorization of children into malnourished and normally nourished groups. Lack of evidence for an ...

Encephalitozoon cuniculi is a parasite that causes encephalitozoonosis in animals and humans. Rabbits and rodents may be infected with EC, resulting in chronic disease. Infection can persist for a long time without clinical signs. To avoid misleading experimental results, laboratory animals should be tested before use. Note that the disease can occur sporadically, and is apparently unrelated to the age or sex of the animals. Clinical signs include stunted growth and signs of central nervous damage due to granulomatous encephalitis and nephritis. Other diseases can, however, give rise to the same neurological symptoms, which can make correct diagnosis difficult. Medicagos Carbon Immuno Assay is a quick (5-minute) and easy test to screen populations of rabbits and guinea pigs for encephaliotozoonosis, or to verify a putative clinical diagnosis of E. cuniculi infection. Sera from some other animal species and humans can also be tested. The kit contains reagents and controls necessary to perform 100 CIA

The microsporidian Thelohania sp. has previously been found to increase its prevalence in crayfish populations inhabiting acidified and urbanized waters. Watershed clearcut logging is the most widespread land-use modification to which Canadian boreal lakes are exposed. The present study investigated whether a stress-response of increased Thelohania can be used as an early biomonitor of the health and viability of crayfish (Orconectes virilis) inhabiting such watersheds. Prevalences remained low (|1.5%) in 4 coldwater fishery lakes over an 8-year period irrespective of experimental clearcutting. In contrast, microsporidosis was elevated in warmwater fishery lakes in 6 clearcut watersheds (6.1%) compared to warmwater fishery lakes in 5 forested watersheds (0.3%). These latter prevalence differences were unrelated to differences in lake temperature, host population abundance, and possible secondary-host minnow abundance between the two sets of warmwater fishery lakes. Instead, the differences may

2. Center for Research Informatics, The University of Chicago, 5751 S. Woodlawn Avenue, Chicago, IL 60637, USA. Zebrafish excel as a model organism for developmental biology and disease modeling. Traditionally, laboratory zebrafish have been maintained as outbred populations with high genetic variability. Our recent work has examined the core MHC locus in zebrafish, where we found alternative pathways of antigen processing and presentation genes that are separated by 500 million years of evolution. Here we performed highcoverage genomic sequencing for two clonal lines of zebrafish, and one partially inbred zebrafish, to uncover additional sources of immune gene variation throughout these genomes. Pathway analysis identified immune genes as highly enriched among genes under positive selection, or associated with structural variation. Overall, zebrafish genomes are enriched by approximately 5 fold higher levels of variation compared with humans, including SNVs, small indels, and structural ...

Background Microsporidia, parasitic fungi-related eukaryotes infecting many cell types in an array of pets (including human beings), represent a significant health risk in immunocompromised sufferers. of 29 regular proteins kinase sequences within the Electronic. cuniculi genome, aswell as 3 genes encoding atypical proteins kinases. The microsporidian kinome presents stunning distinctions from those of various other eukaryotes, which Rabbit Polyclonal to DNA Polymerase zeta minimal kinome underscores the need for conserved proteins kinases involved with essential mobile procedures. ~30% of its kinases are expected to regulate cellular cycle development while another ~28% havent any identifiable homologues in model eukaryotes and so are likely to reveal parasitic adaptations. Electronic. cuniculi does not have MAP kinase cascades and virtually all proteins kinases that get excited about stress reactions, ion homeostasis and nutritional signalling within the model fungi S. cerevisiae and S. ...

In a previous publication we described the development of methods for concentration and purification of E. bieneusi spores from human with watery diarrheic stool, which led to the production of rabbit polyclonal specific antibody (27). In this communication we describe the generation and characterization of eight MAbs against E. bieneusi using the same concentration and purification procedures. Despite four immunizations and six fusion attempts, we were unsuccessful in our attempts to immortalize IgG-producing hybridoma. Carbohydrate antigens are known to induce strong IgM responses (4), but despite treatment with periodate and enzymatic deglycosylation, no loss of reactivity of any of the eight MAbs was observed. Since lipids are also known to induce strong IgM responses (17), the MAbs will be evaluated accordingly. It is important to point out that fixation of spores with methanol for 10 min, which is a known lipid solubilizer (21), almost entirely eliminated reactivity of six MAbs and reduced ...

Our results show that TLR4 plays a major role in activation of splenic DC during E. cuniculi infection, which results in initiation of a protective immune response. While increases in TLR4 transcript and surface protein expression on splenic DC were observed, the expression of other important TLRs (TLR2 and TLR9) remained the same. The data presented in this paper demonstrate that TLR4 expressed by DC signals through the MyD88 adapter molecule and that in vitro blockade of this receptor reduces the expression of MHC class II costimulatory molecules, as well as IL-12p40 production by these cells. This significantly decreases the ability of DC to prime an optimal T-cell response against E. cuniculi. These results emphasize the role of the TLR4 molecule in initiating immunity against this pathogen.. TLR signaling on DC is involved in the immune responses to numerous pathogens (18, 36, 39). Specifically, TLR4 has been demonstrated to be one of the molecules stimulated in several infectious diseases ...
