Microsporidia are obligate intracellular parasites that infect a wide range of eukaryotes, causing severe diseases in immunocompromised humans and losses to apiaries, fisheries and silk farms. They have often been considered to be primitive eukaryotes; however, more recent evidence suggests they are more closely related to fungi.
Microsporidia have been known for some time to possess among the smallest genomes of any eukaryote. There is now a completely sequenced microsporidian genome, as well as several other large-scale sequencing efforts, so the nature of these genomes is becoming apparent. This paper reviews some of the characteristics of microsporidian genomes in general, and some of the recent discoveries made thr...
Comparative small subunit rDNA sequence analyses, indicate that Ovavesicula popilliae, a microsporidian parasite of the Japanese beetle, Popillia japonica, represents a distant sister group to Paranosema and Antonospora. These three genera represent a second major group (the Nosema/Vairimorpha clade representing the first) of Microsopridia which infect terrestrial insects, suggesting independen...
Background and Purpose: Gastroenteritis and the clinical profile caused by Microsporidia, an opportunistic pathogen, may be severe in immunocompromised individuals, especially in AIDS patients. Conventionally, it is necessary to detect the small infective spores in stained smears. However, due to the limitations of the microscopy-based methods, several DNA-based methods such as polymerase cha...
he incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. it occurs mostly in patients in the 6th decade of their life. of all the small bowel diverticuli, jejunal diverticulum is the most common type. this rare entity is usually asymptomatic. however, they may cause chronic non-specific symptoms for a long period of time ...
