Oh my god.... Can you ask them for a pic and send it to me, that is ridiculous, seriously, zoologist? There are pics all over VIN of parasites if they never dealt with frog before...
I mean how long are they doing this test? The test itself probably took them an hour all together, including time needed to take microscope out of storage room and clean every single part of it lol everything else is plain dragging time.
Anyhow, pm me if needed, im not around here much for a few days
