Detection of the microsporidian parasite Enterocytozoon bieneusi in specimens from patients with AIDS by PCR.

ABSTRACT: Microsporidia are protozoa parasites responsible for significant gastrointestinal disease in patients infected with human immunodeficiency virus. We evaluated a PCR assay of stool samples, duodenal aspirates, and biopsy specimens from patients with Enterocytozoon bieneusi infection. A 210-bp DNA fragment of the unique rRNA intergenic spacer could be amplified from all samples infected with E. bieneusi, but no amplification was seen by using DNA purified from samples with Septata intestinalis or other parasites and from negative control human cells. These results suggest that the PCR in stool samples may be a useful tool for the diagnosis of intestinal microsporidiosis in patients with AIDS.

Identification of an Enterocytozoon bieneusi-like microsporidian parasite in simian-immunodeficiency-virus-inoculated macaques with hepatobiliary disease.

Project description:Enterocytozoon bieneusi is a common opportunistic pathogen of human patients with acquired immune deficiency syndrome (AIDS) causing significant morbidity and mortality. In a retrospective analysis utilizing conventional histochemical techniques, in situ hybridization, polymerase chain reaction, and ultrastructural examination, we identified 18 simian-immunodeficiency-virus-infected macaques (16 Macaca mulatta, 1 M. nemestrina, and 1 M. cyclopis) with Enterocytozoon infection of the hepatobiliary system and small intestine. The organisms were readily identified in the bile ducts and gall bladder by special stains and by in situ hybridization using a probe directed against the small subunit ribosomal RNA of human origin E. bieneusi. Infection of the biliary system was associated with a nonsuppurative and proliferative cholecystitis and choledochitis. Hepatic involvement was characterized by bridging portal fibrosis and nodular hepatocellular regeneration accompanied by marked bile ductular and septal duct hyperplasia. Ultrastructurally, all developmental stages of the organism were found in direct contact with the host cell cytoplasm; spores and sporoblasts contained a double layer of polar tubes. Sequencing of a 607-bp segment of the small subunit ribosomal RNA revealed 97 and 100% identity to two clones of small subunit ribosomal RNA derived from E. bieneusi of human origin. Extensive morphological and genetic similarities between the simian and human enterocytozoons suggest that experimentally infected macaques may serve as a useful model of microsporidial infection in AIDS.

Specific PCR assay for direct detection of intestinal microsporidia Enterocytozoon bieneusi and Encephalitozoon intestinalis in fecal specimens from human immunodeficiency virus-infected patients.

Project description:A routine assay based on the PCR was developed for the detection of Enterocytozoon bieneusi and Encephalitozoon intestinalis in fecal samples. Two oligonucleotide primer pairs from a conserved region in the small-subunit rRNA genes of E. bieneusi (primer pair V1 and EB450) and E. intestinalis (primer pair V1 and SI500) were used to amplify microsporidian DNA. We achieved specific amplification of a 382-bp DNA fragment in E. intestinalis and a 353-bp DNA fragment in E. bieneusi. Boiling of the samples appeared to be most effective for DNA extraction. Fecal samples containing fewer than 10 microsporidia gave a positive result in the PCR assay. Fecal specimens from 30 human immunodeficiency virus-infected patients with microsporidiosis and fecal specimens from 42 patients suspected of having microsporidiosis were investigated by the PCR assay. The PCR assay was validated against standard staining methods (the Uvitex 2B and Chromotrope 2R staining methods) and immunofluorescence assay specific for E. intestinalis. This comparative study has shown that PCR improved species determination and can thus be considered a fast and reliable method for the detection and identification of each intestinal species.

Detection and identification of Enterocytozoon bieneusi and Encephalitozoon species in stool and urine specimens by PCR and differential hybridization.

Project description:Several species of microsporidia can cause disease in humans in both immunocompromised and immunocompetent individuals. Enterocytozoon bieneusi and Encephalitozoon intestinalis are most commonly associated with chronic diarrhea. All Encephalitozoon species, including E. intestinalis, E. hellem, and E. cuniculi, also cause disseminated infections. As distinctive treatment options are available for the different genera, identification is clinically important. We evaluated a PCR with primers directed to a conserved region of the small subunit rRNA gene of microsporidia. Hybridization with a generic microsporidium probe and specific probes for each of the four different species was used for identification. Probes were labeled with ruthenium and detected by electrochemiluminescence. The sensitivity of the assay was tested with plasmids containing the region of interest from each of the four different species and Vittaforma corneae as a control. In addition, the assay was tested with feces spiked with cultured spores from each of the three Encephalitozoon species and V. corneae. An analytical sensitivity of 3.5 x 10(2) to 3.5 x 10(3) spores per g of feces, corresponding to 17 to 170 gene copies per PCR, was found, which is several orders of magnitude more sensitive than microscopy after Uvitex 2B fluorescent staining. Stool samples from 22 microscopically diagnosed patients and from 61 uninfected controls were evaluated, showing a sensitivity of at least 95% and a specificity of 100% compared to microscopy. The method was further tested by spiking urine samples with spores of the different Encephalitozoon species.

Host-specific segregation of ribosomal nucleotide sequence diversity in the microsporidian Enterocytozoon bieneusi.

Project description:Enterocytozoon bieneusi is a unicellular enteric fungal pathogen and the most common cause of human microsporidiosis. The frequent detection of this organism in animals, including companion animals, livestock and wildlife, has raised the question of the importance of animal reservoirs in the epidemiology of this pathogen. A partial sequence of the ribosomal internal transcribed spacer (ITS) has been widely used as a genetic marker for studying the molecular epidemiology of E. bieneusi. With the aim of comparing E. bieneusi ITS genotypes originating from different host species, and assess the potential for zoonotic transmission, E. bieneusi ITS sequences retrieved from GenBank were analyzed using two metrics of diversity, rarefaction and phylogenetic distance. In spite of the human ITS sample being geographically more diverse, ITS sequence diversity in animals exceeded that of humans. In both host groups much of the ITS diversity remains to be sampled. Using quantitative phylogenetic tests we found evidence for a partial but significant segregation of E. bieneusi ITS sequences according to host species. Host-specific segregation was confirmed by hierarchical analysis of molecular variation. To improve our understanding of the epidemiology of human microsporidiosis and strengthen the study of E. bieneusi populations, efforts to genotype additional E. bieneusi isolates from wildlife and companion animals should be prioritized and the geographic and species diversify of animal samples should be increased. Due to the possibility of genetic recombination in this species, additional unlinked genetic markers need to be developed and included in future studies.

The reduced genome of the parasitic microsporidian Enterocytozoon bieneusi lacks genes for core carbon metabolism.

Project description:Reduction of various biological processes is a hallmark of the parasitic lifestyle. Generally, the more intimate the association between parasites and hosts the stronger the parasite relies on its host's physiology for survival and reproduction. However, some systems have been held to be indispensable, for example, the core pathways of carbon metabolism that produce energy from sugars. Even the most hardened anaerobes that lack oxidative phosphorylation and the tricarboxylic acid cycle have retained glycolysis and some downstream means to generate ATP. Here we describe the deep-coverage genome resequencing of the pathogenic microsporidiian, Enterocytozoon bieneusi, which shows that this parasite has crossed this line and abandoned complete pathways for the most basic carbon metabolism. Comparing two genome sequence surveys of E. bieneusi to genomic data from four other microsporidia reveals a normal complement of 353 genes representing 30 functional pathways in E. bieneusi, except that only 2 out of 21 genes collectively involved in glycolysis, pentose phosphate, and trehalose metabolism are present. Similarly, no genes encoding proteins involved in the processing of spliceosomal introns were found. Altogether, E. bieneusi appears to have no fully functional pathway to generate ATP from glucose. Therefore, this intracellular parasite relies on transporters to import ATP from its host.

Patterns of genome evolution among the microsporidian parasites Encephalitozoon cuniculi, Antonospora locustae and Enterocytozoon bieneusi.

Project description:Microsporidia are intracellular parasites that are highly-derived relatives of fungi. They have compacted genomes and, despite a high rate of sequence evolution, distantly related species can share high levels of gene order conservation. To date, only two species have been analysed in detail, and data from one of these largely consists of short genomic fragments. It is therefore difficult to determine how conservation has been maintained through microsporidian evolution, and impossible to identify whether certain regions are more prone to genomic stasis.Here, we analyse three large fragments of the Enterocytozoon bieneusi genome (in total 429 kbp), a species of medical significance. A total of 296 ORFs were identified, annotated and their context compared with Encephalitozoon cuniculi and Antonospora locustae. Overall, a high degree of conservation was found between all three species, and interestingly the level of conservation was similar in all three pairwise comparisons, despite the fact that A. locustae is more distantly related to E. cuniculi and E. bieneusi than either are to each other.Any two genes that are found together in any pair of genomes are more likely to be conserved in the third genome as well, suggesting that a core of genes tends to be conserved across the entire group. The mechanisms of rearrangments identified among microsporidian genomes were consistent with a very slow evolution of their architecture, as opposed to the very rapid sequence evolution reported for these parasites.

Development and application of genetic probes for detection of Enterocytozoon bieneusi in formalin-fixed stools and in intestinal biopsy specimens from infected patients.

Project description:The microsporidium Enterocytozoon bieneusi is closely linked to wasting and diarrhea in a high proportion of individuals with AIDS. However, its relative contribution to disease is uncertain because diagnosis until recently depended on procedures involving endoscopy. A sensitive PCR technique which amplifies a fragment of the small-subunit rRNA gene of E. bieneusi from formalin-fixed stool samples was developed. Of 80 formalin-fixed stool samples collected from 74 Zimbabweans and 6 U.S. patients who were human immunodeficiency virus positive, 50% tested positive for E. bieneusi by PCR, whereas 24% tested positive for E. bieneusi by light microscopy of trichrome-stained fecal smears. In addition, we describe an in situ hybridization technique which detected and identified E. bieneusi as the causative agent in all six intestinal biopsy specimens tested. Both the PCR and in situ hybridization procedures are sensitive diagnostic tools which will complement currently available techniques and enable the differentiation of E. bieneusi from other microsporidia to be made.

Infection by and genotype characteristics of Enterocytozoon bieneusi in HIV/AIDS patients from Guangxi Zhuang autonomous region, China.

Project description:Enterocytozoon bieneusi has been increasingly reported to infect humans and various mammals. Microsporidia cause diarrhea in HIV-infected patients worldwide. PCR amplification and sequencing based on the internal transcribed spacer region have been used to describe the genotypes of E. bieneusi and transmission of microsporidiosis.In this study, we examined E. bieneusi infection and genotypes in HIV-positive patients in Guangxi, China. Stool specimens were collected from 285 HIV-positive patients and 303 HIV-negative individuals. E. bieneusi genotypes were characterized using nested PCR and sequencing.Thirty-three (11.58%) HIV-positive patients were infected with microsporidia, and no infection was found in the 303 healthy controls. Three new genotypes were identified and named as GX25, GX456, and GX458; four known genotypes, PigEBITS7, Type IV/K, D, and Ebpc, were also identified. Our data showed that the positive rate for microsporidia was significantly higher in the rural patients than in the other occupation groups. In addition, the positive rate for microsporidia was significantly higher in the patients who drink unboiled water than in those with other drinking water sources.Our results will provide baseline data for preventing and controlling E. bieneusi infection in HIV/AIDS patients. Further studies are required to clarify the epidemiology and potential sources of microsporidia. Our study showed that microsporidium infection occurs in the HIV/AIDS patients in Guangxi, China.
