Encephalitozoon cuniculi Genotype III Evinces a Resistance to Albendazole Treatment in both Immunodeficient and Immunocompetent Mice.

Antimicrob Agents Chemother 2020 Apr 21;64(5). Epub 2020 Apr 21.

Institute of Parasitology, Biology Centre, Czech Academy of Science, České Budějovice, Czech Republic.

Of four genotypes of , genotype II is considered to represent a parasite that occurs in many host species in a latent asymptomatic form, whereas genotype III seems to be more aggressive, and infections caused by this strain can lead to the death of even immunocompetent hosts. Although albendazole has been considered suitable for treatment of species, its failure in control of genotype III infection has been reported. This study determined the effect of a 100× recommended daily dose of albendazole on an genotype III course of infection in immunocompetent and immunodeficient mice and compared the results with those from experiments performed with a lower dose of albendazole and genotype II.

Department of Pathology, Faculty of Medicine, Alexandria University, Egypt.

Despite the fact that many approaches have been developed over years to find efficient and well-tolerated therapeutic regimens for microsporidiosis, the effectiveness of current drugs remains doubtful, and effective drugs against specific targets are still scarce. The present study is the first that was designed to evaluate the potency of auranofin, an anti-rheumatoid FDA approved drug, against intestinal Encephalitozoon intestinalis. Evaluation of the drug was achieved through counting of fecal and intestinal spores, studying the intestinal histopathological changes, measuring of intestinal hydrogen peroxide level, and post therapy follow-up of mice for 2 weeks for detection of relapse.

Combining fish and environmental PCR for diagnostics of diseased laboratory zebrafish in recirculating systems.

PLoS One 2019 12;14(9):e0222360. Epub 2019 Sep 12.

Research Unit Comparative Medicine, Helmholtz Zentrum München, German Research Center for Environmental Health, Neuherberg, Germany.

Precise knowledge of the health status of experimental fish is crucial to obtain high scientific and ethical standards in biomedical research. In addition to the use of sentinel fish, the examination of diseased fish is a fundamental part of all health monitoring concepts. PCR assays offer excellent sensitivity and the ability to test a broad variety of pathogenic agents in different sample types. Read More

Potential impacts of host specificity on zoonotic or interspecies transmission of Enterocytozoon bieneusi.

Infect Genet Evol 2019 11 5;75:104033. Epub 2019 Sep 5.

Key Laboratory of Zoonosis of Ministry of Agriculture, College of Veterinary Medicine, South China Agricultural University, Guangzhou, Guangdong 510642, China. Electronic address:

Microsporidia are composed of a highly diverse group of single-celled, obligate intracellular fungi that colonize an extremely wide range of other eukaryotes, among which Enterocytozoon bieneusi is the most common species responsible for human microsporidiasis. Genotyping of E. bieneusi based on sequence analysis of the ribosomal internal transcribed spacer (ITS) has recognized ~500 genotypes in humans and a great variety of other mammals and birds.

Comparison of infectious agents detected from hatchery and wild juvenile Coho salmon in British Columbia, 2008-2018.

PLoS One 2019 3;14(9):e0221956. Epub 2019 Sep 3.

Pacific Biological Station, Fisheries and Oceans Canada, Nanaimo, BC, Canada.

Infectious diseases are potential contributors to decline in Coho salmon (Oncorhynchus kisutch) populations. Although pathogens are theoretically considered to pose higher risk in high-density rearing environments like hatcheries, there is no direct evidence that hatchery-origin Coho salmon increase the transmission of infectious agents to sympatric wild populations. This study was undertaken to compare prevalence, burden, and diversity of infectious agents between hatchery-reared and wild juvenile Coho salmon in British Columbia (BC), Canada. Read More

Institute for Transplantation, Urology and Nephrology (ITUN) Nantes University Hospital, 44000 Nantes, France.

Introduction: Gastrointestinal disorders in solid organ recipients may have various origins including cryptosporidiosis and microsporidiosis. The prevalence of these infections is poorly known in solid organ transplant (SOT) patients in industrialized countries.

Methods: We prospectively assessed the infectious causes of diarrhea in SOT patients. Read More

Identification of Enterocytozoon bieneusi in goats and cattle in Thailand.

BMC Vet Res 2019 Aug 28;15(1):308. Epub 2019 Aug 28.

Department of Protozoology, Faculty of Tropical Medicine, Mahidol University, Ratchawithi Road, Ratchathewi, Bangkok, 10400, Thailand.

Background: Enterocytozoon bieneusi has been increasingly reported to infect domestic animals and humans, with human infections primarily reported as zoonotic in origin. The aim of the present study was to determine the presence and genotype of E. bieneusi in humans and domestic animals in central Thailand by testing stool samples of 200 apparently healthy humans, 73 goats, 60 cattle and 65 pigs using nested-PCR/ sequence analysis based on the ITS region of SSU rRNA genes.

Genotyping Approach for Potential Common Source of Enterocytozoon bieneusi Infection in Hematology Unit.

Emerg Infect Dis 2019 09;25(9):1625-1631

Microsporidiosis is a fungal infection that generally causes digestive disorders, especially in immunocompromised hosts. Over a 4-day period in January 2018, 3 patients with hematologic malignancies who were admitted to the hematology unit of a hospital in France received diagnoses of Enterocytozoon bieneusi microsporidiosis. This unusually high incidence was investigated by sequence analysis at the internal transcribed spacer rDNA locus and then by 3 microsatellites and 1 minisatellite for multilocus genotyping.

Infection patterns, clinical significance, and genetic characteristics of Enterocytozoon bieneusi and Giardia duodenalis in dairy cattle in Jiangsu, China.

Parasitol Res 2019 Oct 16;118(10):3053-3060. Epub 2019 Aug 16.

Key Laboratory of Zoonosis of Ministry of Agriculture, College of Veterinary Medicine, South China Agricultural University, 483 Wushan Road, Guangzhou, 510642, China.

The infection patterns and clinical significance of Enterocytozoon bieneusi and Giardia duodenalis in dairy cattle remain poorly investigated despite their common occurrence. Data on the genetic diversity are also needed to understand the transmission and human-infective potential of the two pathogens. In this study, fecal specimens from 1366 dairy cattle on a large farm were examined for the presence and genotype distribution of E. Read More

Genome-Wide Identification of Long Non-Coding RNAs and Their Regulatory Networks Involved in Response to Infection.

Insects 2019 Aug 9;10(8). Epub 2019 Aug 9.

College of Bee Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China.

Long non-coding RNAs (lncRNAs) are a diverse class of transcripts that structurally resemble mRNAs but do not encode proteins, and lncRNAs have been proven to play pivotal roles in a wide range of biological processes in animals and plants. However, knowledge of expression patterns and potential roles of honeybee lncRNA response to infection is completely unknown. Here, we performed whole transcriptome strand-specific RNA sequencing of normal midguts of workers (Am7CK, Am10CK) and -inoculated midguts (Am7T, Am10T), followed by comprehensive analyses using bioinformatic and molecular approaches.
