| The SFTSV-infected Vero cell monolayer was fixed according to described methods and cut on ultramicrotome at 65 nm. |
| Slices of 150 nm thicknesses were cut with an ultramicrotome. |
| Thin sections were cut with an ultramicrotome and diamond knife and stained with lead citrate. |
| After resin polymerisation, the samples were cut using an ultramicrotome in 100 nm-thick slices. |
| Specimens were thick sectioned for the presence of the archegonia and thin-sectioned with a diamond knife on an Ultracut-E ultramicrotome. |
| Cross-sections were cut using an ultramicrotome and stained with safranin and light green. |
