A survey of mosquito larvae infected with microsporidia was conducted from 2005 to 2008 in the Tomsk, Kemerovo and Novosibirsk regions of western Siberia, Russia. Twenty-one morphologically and genetically unique species of microsporidia were isolated from nine species of Anopheles, Aedes, Culex and Ochlerotatus mosquitoes including: (1) 14 proposed new species of Amblyospora (A. bakcharia, A. ...

The minireview in the Journal of Clinical Microbiology by Ramanan et al. (1) mentions that microsporidia may cause keratitis, particularly in contact lens wearers. We wish to highlight another risk factor that may be less well recognized because of a lack of awareness. Microsporidia are a major nonbacterial cause of keratoconjunctivitis in Singapore. A retrospective review of 124 cases confirme...

Long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) have resulted in a major decrease malaria transmission. However, it has become apparent that can be effectively transmitted despite high coverage of LLINs/IRS. Residual transmission occur due to Plasmodium -carrying Anopheles mosquitoes are insecticide resistant feeding resting behavior reduces their chance encountering t...

The sub-3 Mbp genomes from microsporidian species of the Encephalitozoon genus are the smallest known among eukaryotes and paragons of genomic reduction and compaction in parasites. However, their diminutive stature is not characteristic of all Microsporidia, whose genome sizes vary by an order of magnitude. This large variability suggests that different evolutionary forces are applied on the g...

Microsporidia and Cryptosporidium species are prominent agents of enteritis, capable of causing severe chronic diarrhoea in children, immunocompetent and immunocompromised individuals around the world. It is not possible to identify the parasites at species level solely on the basis of microscopy. The aim of the present study was to identify and characterize the species of Microsporidia and Cry...

Encephalitozoon microsporidia are obligate intracellular protozoan parasites that proliferate and differentiate within a parasitophorous vacuole inside host cells that are usually epithelial in nature. Isolates of the three species of the Encephalitozoon microsporidia, E. cuniculi, E. hellem, and E. intestinalis, were obtained from AIDS patients and cultured in green monkey (E6) kidney cells. A...

Abstract Zebrafish are a powerful model organism to study disease. Like other animal models, Danio rerio colonies are at risk of pathogenic infection. Microsporidia, a group of intracellular fungus-like parasites, are one potential threat. Microsporidian spores germinate and spread causing pathological changes in the central nervous system, skeletal muscle, and other anatomic sites. Infection c...

Molecular tools of the intracellular protozoan pathogens Apicomplexa and Kinetoplastida for manipulation of host cell machinery have been the focus of investigation for approximately two decades. Microsporidia, fungi-related microorganisms forming another large group of obligate intracellular parasites, are characterized by development in direct contact with host cytoplasm (the majority of spec...
