Early experiences with microsporidia of man and mammals.
Comparative data are given of microsporidian infections in insects and mammals. Due to minute size and diffuse distribution in mammals microsporidia were recognized in vertebrates only during search for virus infections. Early infections with Encephalitozoon in rearings of laboratory animals contaminated many isolates of other protozoan infections. Old separate descriptions of microsporidia in mice, rabbits or dogs have to be reevaluated with modern methods of molecular analysis. Old cases of infection of man known now as Encephalitozoon chagasi or Encephalitozoon sp. Matsubayashi are not belonging to the genus Encephalitozoon and should be jointly studied with Nosema connori as eventually identical. With actual improvements of methods of diagnostics the net of detection of microsporidia in man should be extended on routine testing of urine, faecal samples, eye and nose biopsies and other materials including vaginal smears. The way of circulation of the infections in the host organisms must be studied.
