It's #MicroscopeMonday - and this week, we're looking at gametes.
Our science and vet teams evaluate the concentration, health and movement of sperm - just like in a fertility clinic for humans.
Like our endocrinology testing, this is all to support our conservation breeding work.

Parasites are not uncommon in Wildife and it is important to discern if it is a problem or not. In this case, there does not appear to have been weight loss nor damage to the intestine so they are incidental.

Happy #MicroscopeMonday featuring normal histology of a big brown bat wing! 🦇
In bats affected with white nose syndrome, we would look for the fungal causative agent, Pseudogymnoascus destructans, in the wing membranes and grade the level of damage affecting them! Big brown bats can be resistant!

Sarcocystis sp. are relatively common in wildlife species with variability on mortality. Can be deadly if the animal is immunosuppressed and migrates to the brain 🧠 causing severe inflammation and necrosis.
