Abstract
AIM: To introduce an effective method of immunogold electron microscopy for the detection of nanobacteria.
METHODS: Nanobacteria were fixed in the 25 g/L glut-araldehyde, and then were embedded in resin. After they were cut into ultrathin slices by diamond knife, an indirect immunogold electronic microscopy staining was performed on the nanobacteria using the specific antibody of nanobacteria.
RESULTS: The nanobacteria were ball- or stick-like with a length of 80-350 nm under electron microscope. Nanobacteria were combined with the specific antibo-dy. The adhesion of the immune colloidal gold granule was observed under the electronic microscopy.
CONCLUSION: The immune electronic microscopy can not only reveal the ultrastructure of nanobacteria, but also indicate its special antigenicity.
