Recently, Some domestic and wild animals have been found to be naturally infected with E. intestinalis and some other microsporidian species.
Research has proven that E. intestinalis infection can increase host cell nuclear mutation rate.
[5] Microsporidia are obligate intracellular opportunistic fungi that cause significant pathology in immunocompromised (simply put: having an impaired immune system) hosts.
E. intestinalis lack large gene blocks of sequence in its subtelomeric regions unlike E. cuniculi.
[7] Frequent washing of hands and limited exposure to animals is highly recommended especially for people with immunesystem deficiency.
