Day 7, Dr Sarah Poynton from the John Hopkins Medical Institute, presents at Aquavet 2.
“Parasitos” = to eat at another’s table.
Parasites are organisms that they are nutritionally dependent on their host.
They’re not always primary pathogens.
Did you know that Microsporidia are now considered to be more closely related to fungi?
And that Myxosporea are now considered to be more closely related to metazoa?
Some of these bugs are difficult to visualise under normal HE stained histological sections. So what are some useful histological stains that can be used to help with visualising the very small parasites?
- Gram
- ZN
- Giemsa
- PAS
- Protargol (similar to GMS, a silver stain)
- DAPI
- Feulgen
Other techniques include
- Normarski (differential interference contrast).
- Wet preparations (to visualise movement)
Dr Loh’s trip to attend AquaVet has been made possible through the – “People development program: 2011 Aquatic Animal Health Training Scheme which is supported by funding from the FRDC on behalf of the Australian Government”.
