In April 2014, a kidney transplant recipient in the United States experienced headache, diplopia, and confusion, followed by neurologic decline and death. An investigation to evaluate the possibility of donor-derived infection determined that 3 patients had received 4 organs (kidney, liver, heart/kidney) from the same donor. The liver recipient experienced tremor and gait instability; the heart/kidney and contralateral kidney recipients were hospitalized with encephalitis. None experienced gastrointestinal symptoms...

Encephalitozoon cuniculi is an important microsporidian pathogen that is considered an emergent, zoonotic, and opportunistic. It infects both domestic and laboratory rabbits, generating severe chronic interstitial and granulomatous nephritis with fibrosis and granulomatous encephalitis. Encephalitozoonosis is diagnosed in paraffin-embedded sections by examining the spores in the host tissues. The spores are difficult to observe when the samples are stained with hematoxylin and eosin (H&E), particularly when there is an inflammatory reaction and tissue damage...

Microsporidia are opportunistic pathogens in nature infecting all animal phyla. There is a potential risk of microsporidian spores transmission from urban rooks inhabiting some metropolitan cities to people through casual interactions. The aim of this study was to identify microsporidia species in the droppings of rooks in Wroclaw, Poland. A total of 15 collective sets of droppings were examined using nested-PCR method. Amplification of ITS rRNA gene revealed the presence of Enterocytozoon bieneusi D, Peru 6 and Encephalitozoon hellem 1A genotypes...

Most studies of opportunistic infections focus on immunocompromised patients. However, there is a lack of information on microsporidiosis in healthy people (immunocompetent) worldwide. This study aimed to detect and identify microsporidia species in immunocompetent Orang Asli living in Pahang, Malaysia. Orang Asli is a collective term for a group of indigenous people that usually reside in the interior regions of Peninsular Malaysia. They comprise about 0.7% of the total population in Malaysia and 76% of them lived below the poverty line i...

Diagnosis of Encephalitozoon cuniculi infection in rabbits remains a major veterinary issue. ELISA or immunofluorescence assays are the current reference standards of serological tests. However, these conventional techniques suffer from a lack of accuracy for distinguishing active from past infections, as a positive serostatus is common in clinically normal rabbits. In this study, we assessed the diagnostic performance of Western blot (WB) to detect both anti-E. cuniculi immunoglobulin G (IgG) and immunoglobulin M (IgM) in comparison with ELISA and to address the intensity of the immune response through a quantitative approach...

Encephalitozoon cuniculi is an opportunist intracellular pathogen of mammals. The adaptive immune response is essential to eliminate E. cuniculi, but evidence is mounting that the response initiated by the innate immune response may ultimately define whether or not the parasite can survive. B-1 cells may act as antigen-presenting cells or differentiate into phagocytes, playing different roles in many infection models. However, the role of these cells in the dynamics of Encephalitozoon sp. infections is still unknown...

The microsporidian parasite designated here as Nosema sp. Isolate YNPr was isolated from the cabbage butterfly Pieris rapae collected in Honghe Prefecture, Yunnan Province, China. The genome was sequenced by Illumina sequencing and compared to those of two related members of the Nosema/Vairimorpha clade, Nosema ceranae and Nosema apis. Based upon assembly statistics, the Nosema sp. YNPr genome is 3.36 x 106bp with a G+C content of 23.18% and 2,075 protein coding sequences. An "ACCCTT" motif is present approximately 50-bp upstream of the start codon, as reported from other members of the clade and from Encephalitozoon cuniculi, a sister taxon...

A 2-month-old juvenile central bearded dragon was presented for anorexia and cachexia. Another specimen from the same cage had died suddenly 2 weeks prior. Fecal analysis revealed a high quantity of Isospora amphiboluri and a few pinworm eggs. Other examinations were not performed and the animal died a few days later despite supportive care. A third individual from the same cage presented with anorexia and a distended cœlom and was euthanized. In this third dragon, histological examination revealed intestinal coccidiosis, basophilic intranuclear inclusions compatible with adenovirus infection, acute hepatic necrosis with intrahepatocytic and intraenteritic organisms typical of microsporidia and renal gout...

Antibodies to Encephalitozoon cuniculi (E. cuniculi) were examined by enzyme-linked immunosorbent assay using E. cuniculi PTP2 recombinant protein from serum samples that had been collected from a total of 295 cats in Japan. Of these samples, 6.1% (18/295) had antibodies against E. cuniculi, which included 6.3% (6/96) of the male cats and 6.0% (12/199) of the female cats. The incidence was slightly higher in feral cats (8.3%, 11/132) compared to domesticated cats (4.3%, 7/163). This suggests the possibility that the cats of our country have become a reservoir of E...

INTRODUCTION: Microsporidia spp. are ubiquitous and infect a wide variety of intervertebrates and vertebrates, including humans. Pulmonary microsporidiosis, characterized by nonspecific symptoms like fever, cough and dyspnea, is often overlooked in the differential diagnosis of pulmonary infections in immunsupressed patients. In this study, we aimed to determine the prevalence of pulmonary microsporidiosis in iatrogenically immunosuppressed patients and to evaluate the patient characteristics...

We developed nested PCR protocols and performed a multiyear survey on the prevalence of several protozoan parasites in wild northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) in the Rolling Plains ecoregion of Texas and Oklahoma (i.e. fecal pellets, bird intestines and blood smears collected between 2010 and 2013). Coccidia, cryptosporidia, and microsporidia were detected in 46.2%, 11.7%, and 44.0% of the samples (n = 687), whereas histomona and hematozoa were undetected. Coccidia consisted of one major and two minor Eimeria species...

Detection of microsporidia at the species level is important for therapeutic purpose. The available techniques, modified trichrome (MT) staining cannot differentiate between species, while polymerase chain reaction (PCR) requires a reference laboratory and skilled technical staff. Immunoflourescence antibody (IFA) assay is another technique, which can differentiate among commonest species of microsporidia. However, there are very limited studies on its efficacy worldwide. Therefore, we aimed to evaluate IFA assay for the detection of microsporidia and differentiation among commonest species, Enterocytozoon bieneusi (E...

Levels of interferon (IFN)-γ and interleukin (IL)-10 were measured in the serum of immunocompetent and immunosuppressed New Zealand White rabbits naturally infected with Encephalitozoon cuniculi. IFN-γ levels were elevated in infected rabbits, and a synergic effect was observed in animals treated with the immunosuppressive agent dexamethasone (Dex). The role of IL-10 in infected rabbits remains unclear, as IL-10 levels were similar to those of negative controls. Dex appeared to exhibit a proinflammatory effect, as IFN-γ levels were elevated in infected immunosuppressed rabbits...

Microsporidia cause diarrhea among human immunodeficiency virus (HIV) infected patients worldwide. Enterocytozoon bieneusi and Encephalitozoon intestinalis are the most common species infecting HIV patients. Various genotypes of E. bieneusi are transmitted from human to human (anthroponotic route) or from animal to human (zoonotic route). However, there is no study from India on genotypes of E. bieneusi among infected hosts. Therefore, we aimed to (a) study the prevalence, clinical symptoms, and species identification of microsporidia among HIV infected patients and (b) perform a genotypic analysis of E...
