Are those really SARS-CoV-2 virions in the kidney?

,

Several studies report direct infection of different types of kidney cells by SARS-CoV-2 detected by transmission electron microscopy (TEM) both on post-mortem analysis and kidney biopsy specimens. However, these studies did not include detection of viral RNA or other methods for viral detection of kidney specimens and thus it is unclear whether the observed particles are definitely coronavirions or other similar coated vesicles eg clarthrin coated vesicles, which are comparablein size and morphology. Frelih et al used RT-PCR to identify direct invasion of SARS-Co-V2 in conjunction with TEM analysis on fresh post-mortem lung and kidney specimens of COVID-19 patients.
