Q

cause of MBD

A

Ca+:Phos ratio imbalance - too low calcium to too high phosphorus
calcium deficiency is worsened by vitamin D3 deficiency (make sure you are supplementing the correct type of vitamin D)

Q

are abscesses common in reptiles?

A

yes
increased incidence can occur in juveniles due to: growth demands requiring better husbandry, developing immune system, pair/group housing resulting in cagemate aggression/stress

can also use manual manipulation to help remove eggs

associated with poor nutrition and dehydration

Q

what are factors of a reptile’s ability to excrete excess uric acid?

A

it depends on the amount of protein they are fed, frequency of the protein being fed, and hydration status
if uric acid is not excreted properly, it accumulates in the joints, kidneys, or around organs (liver, spleen, heart, lungs)
it can also accumulate in the mucus membranes in the mouth

visceral gout: accumulation in/around the organs
gout trophi: accumulation in the gingiva

24
Q

articular gout CS

A

raised cream-colored masses on joints of toes, ankles, or wrists; trouble moving due to joint pain and edema

25
sign of gout trophi
mucous membranes in oral cavity have raised whitish spherical swellings
26
gout treatment
fluids, supportive care, surgery is an option to improve pain and mobility (uric acid crystal buildup is scraped out of joints)
27
pyramiding
shell condition caused by husbandry, can be a form of MBD, increased protein in diet, increased fat in diet, low humidity
28
shell rot
shell condition soft or deformed shell, abnormal scute growth
29
SCUD
septicemic cutaneous ulcerative disease can become a generalized illness
30
SCUD treatment
wound debridement, systemic antibiotics prevent through good sanitation
31
what are the methods of shell repair for trauma?
superficial cracks can be repaired with fiberglass cloth impregnated with resin or dental acrylic extensive fractures need to be wire closed first, aid with supportive care while shell slowly heals
32
vitamin A deficiency CS
conjunctivitis, blepharitis (swollen eyelids), nasal d/c, dyspnea, ear abscesses
33
vitamin A deficiency treatment
correct the deficiency and supplement beware of over-supplementation which can cause dry flaky skin and skin sloughing which can lead to secondary infection
34
respiratory infections
common in turtles since they can't clear discharge easily by coughing since they don't have a diaphragm
35
respiratory infections CS
ocular and nasal d/c, dyspnea, sunken eyes, generalized dull coloration, aquatic turtles may lose buoyancy
36
which type of reptile is more prone to developing pneumonia?
snakes with mouth, sinus, or eye infections because of their glottis location (on floor of the mouth)
37
pneumonia pathology
gram-negative pathology
38
pneumonia CS
cyanosis, bubbles from nares/glottis, wheezing, crackling on auscultation, petechia of oral cavity
39
what factors predispose a reptile to contracting pneumonia?
poor husbandry conditions: low cage temperature, inadequate nutrition
40
beak deformities
occur with nutritional osteodystrophy can overgrow and need to be trimmed trauma can cause deformities
41
pinworm parasites
don't usually cause disease in low numbers may support gut health in herbivorous lizards no CS or change in feces seen
42
what can be used as a treatment for a high number of pinworms that is causing infection?
Fenbendazole and clean environment Fenbendazole can cause toxicity so we only use if necessary
43
mite check
mites appear as black/gray/red tiny spots may look like scales but are a different color
44
vesicular dermatitis
snake condition "blister disease"
45
what does a white substance around the nares indicate?
normal excretion of sodium electrolytes
46
vesicular dermatitis causes
poor hygiene: dirty/humid
47
vesicular dermatitis CS
blisters filled with bacteria that cause septicemia and death
48
paramyxovirus
snake respiratory disease mostly seen in vipers no treatment, just supportive care
49
inclusion body disease (IBD)
snake condition viral infection in boids unknown route of transmission but probably arthropods slow progression to neurologic signs: head tremors, disorientation, loss of righting reflex no treatment, all animals eventually die
50
cryptosporidia
snake condition protozoan no safe/effective treatment
51
cryptosporidia infection CS
midbody swelling (prevents proper absorption of food because parasite can live in small intestine), weight loss, regurgitation
52
which type of stain is used to diagnose a cryptosporidia infection?
acid fast stain because the oocytes are very small (< 4 microns)
53
brumation
hibernation
54
what functions does brumation affect?
affects life expectancy (allows them to reach full life expectancy), maintains normal hormonal activity, affects reproductive hormone stimulation/synchronization
55
signs of imminent hibernation
declining appetite, declining activity, burrowing, hiding
56
what is the single most important factor in most reptiles for stimulating ovulation/spermatogenesis?
temperature drop
57
should reptiles be allowed to hibernate?
yes, healthy adults should be allowed to if they have the urge to hibernate semi-hibernation is damaging though
58
what care should be provided during hibernation?
proper humidity with ventilation, dark cool environment, feed balanced diet with vitamin supplement, pull food 10 days prior, soak 2-3x a week, remove heat source for a week, temperature should be 50-55 F for 3-4 months, monitor, weigh every 3 weeks
