squamata
what belongs to the order sphenodontia
tuataras- in new zealand
what makes tuataras different from other reptiles
lizard like, parietal eye, likes colder temps, insectivorous, godzillas.
what do we need to know about UV lighting
does not penetrate glass well
UVB is best for Vit D activation
what are the two reptile viruses
PMV (resp disease)
IBD (flaccid paralysis in snakes)
what is the treatment for PMV
quarantine well and SC
what is the bacti commonly associated with ulcerative stomatitis in reptiles
aeromonas.
what happens secondarily to PMV
pneumonia. nasal bubbling and floating sideways.
why did the FDA ban small turtles
salmonella. most reptiles have it and only show CS when stressed
what is our zoonotic bacteria that causes cutaneous granulomas in reptiles. like fish
mycobacteriosis
what is the clinical signs of hypovitaminosis A
squamous metaplasia of epithelial cells. otitis media, blepharitis, overgrowth of epithelial cell parts
dysecdysis
retained shed
what are the causes of gout primary and secondary?
primary- excess protein, water deprivation
secondary- uric acid accumulation in tissues
visceral or articular
the order anura is ______ while the order caudata is ______
anura- frogs and toads
caudata- salamanders
what is the order for limbless amphibians
gymnophiona
what is a main cause of amphibian diseases
water quality issues. just like fish.
what is red leg disease. what does it look like
aeromona hydrophila secondary to trauma or poor water quality
necrosis and petechiae of the limbs- light pink
what causes chronic wasting disease and skin ulcerations in amphibians. can be mistaken for red leg
mycobacteriosis- zoonotic
white cottony fungus in amphibians- opportunistic
saprolegnia
pigmented granulomas in skin and internal organs of amphibians
chromomycosis- zoonotic potential
thought to be the cause of worldwide decline of many amphibian species. sudden death with no real signs
chytrid - batrachochytrium dendrobatidis
if you see erythema or petechiae on the ventral surface of a amphibian what three things should be on your ddx
chytrid, red leg, myco
why does chytrid kill?
secondary osmoregulatory dysfunction due to cutaneous integrity loss.
what is different about chytrid fungus compared to saprolegnia
chytrid is NONhyphal.
cutaneous infection of frogs. migration of nematodes. treat with ivermectin
capillariasis. can allow secondary myco because opportunistic
what does ranid herpesvirus cause. in who?
renal adenocarcinoma in leopard frog
emerging disease of amphibians that can mimic redleg. also abnormal CNS signs with erythema
irdoviruses
