Isolation and characterization of SMBV. A) SMBV-induced CPEs in an A. castellanii monolayer, which are similar to APMV-induced CPEs; B) SMBV particle visualized by transmission electronic microscopy; C) Morphometry of the SMBV particle, which has an average diameter of approximately 574 nm (a total of 50 particles images were analyzed); D) Detail of the star-gate structure (visualized by electronic microscopy), which is also present in APMV.
