Microsporidia can infect a variety of hosts, including hosts which are themselves parasites. In that case, the microsporidian species is a hyperparasite , i.e. a parasite of a parasite. As an example, more than eighteen species are known which parasitize digeneans (parasitic flatworms ).
Enterocytozoon bieneusi, commonly known as microsporidia, is a unicellular, obligate intracellular eukaryote.Their life cycle includes a proliferative merogonic stage, followed by a sporogonic stage resulting in small, environmentally resistant, infective spores, which is their transmission mode.
Microsporidiosis is an opportunistic intestinal infection that causes diarrhea and wasting in immunocompromised individuals (HIV, for example).It results from different species of microsporidia, a group of microbial (unicellular) fungi.
In microsporidia this is mediated by a unique and highly specialised protein: the polar tube. This specialised protein is found inside the spore and is in contact with the sporoplasm. Specific environmental stimulation causes the spore to discharge the polar tube which penetrates the xenoma membrane and provides an exit route for the sporoplasm.
This is a list of Microsporidia genera: Abelspora [1] Agglomerata [1] Agmasoma [1] [2] Alfvenia [1] Alloglugea [1] Amazonspora [3] Amblyospora [1] [2] Ameson [1] [2 ...
Microsporidia have been found in several nematodes isolated from different locations, indicating that they are common natural parasites of C. elegans. The N. parisii – C. elegans system is a useful tool for studying infection mechanisms of intracellular parasites.
They are commonly found in several household products, including food packaging, toothbrushes, cosmetics, car parts, tools, and toys. One study found a link between phthalates and wheezing and eczema.
Studies of healthy dogs have found a 0–38% prevalence. Cats appear to be relatively resistant to the organism, although experimental infections in kittens with feline leukemia virus have been described. E. cuniculi also infects rodents, and the organism has been detected in the feces of 13% of pet birds. A small percentage of healthy people ...
