Abstract Helium ion scanning microscopy (HIM) is a novel high-resolution scanning microscopy technique that uses
helium ions instead of electrons to form images of the highest quality and resolution, providing a sub-nanometer
resolution sputter uncoated biological cell. Here, we took advantage of HIM to explore the cell surface of
Tritrichomonas foetus, a protist parasite of cattle that provokes hard infection and abortion in cows. We describe thin
protrusions, like nanotubes described in other cells, with different sizes (27 nm to 81 nm in thickness) and various
lengths (from 73 nm to 2 µm), as well bulbous structures either budding from the… More >
