Komodo
is a Bearded Dragon who slowly acquired a severe eye infection.
Both eyes started swelling up and soon Komodo stopped eating.
Reptile
infections often create granulomatous pus, which means their infection
creates lots of extra tissue made out of the white blood cells
that came to help fight the infection. In Komodo, this pus accumulated
in the conjunctival folds until she could no longer see or open
her eyes.
Surgical
extraction of the pus was required on a bi-daily basis for three
days, then saline irrigations flushed the pus from the eyes for
a period of one week. During this time she was hospitalized and
kept at 100 degrees and Ofloxacin ($$$$$) opthalmic antibiotic
was applied through a small catheter into the conjunctival folds.
Eventually, Komodo was feeling better and her infections resolved.
Many
reptile infections are strange species of bacteria that and so
it was important that we cultured the bacteria responsible and
apply the correct antibiotic for that bug. Komodo was infected
with a somewhat nasty bug known as Morganella morganii. Morganella
species are becoming an up-and-coming nosocomial
infection, often resistant to antibiotic therapy and infections
with this species are often responsible for human
hospital deaths. Komodo's bug was challenged with various
antibiotics and found to be resistant to all pennicillins, augmentin,
cephalosporins, chloraphenicol and tetracyclines. This bug was
a pretty nasty fella!
A
classroom pet infected with this particular bacterial organism
is pretty scary. If a child became infected with this organism,
the antibiotic choices would be very limited and if the bug was
to make it into a wound or up to the hospital there could be really
nasty human disease as a result.
Komodo
teaches us two important lessons about reptiles as pets:
- Reptiles
can grow and harbor infectious and zoonotic
disease. Humans in contact with reptiles should practice
safe
reptile handling protocols. (The school
and staff were exceptionally responsible in this realm and all
handlers were being careful throughout the infection this is
mentioned here as a reminder to all!)
- Reptile
illness is usually prevented by proper husbandry, most importantly
proper temperature gradients and thermoclines.
Komodo
is an example of a herp illness that might have been prevented
with better husbandry. Bearded dragons function best at relatively
high temperatures, in the upper 90's, and she had been kept at
lower temps for most of her life, which slowly disables the immune
system and predisposes to infections such as this.
Remember
that everything happens very slowly in reptiles, and even slower
at lower temperatures. If your reptile has any changes in appetite,
shed cycles, or appearance - the chances are good that there is
a husbandry concern that is slowly taking its toll on your friend.
Bringing them into the vet before they really get sick helps us
make a difference before it's too late or expensive.
If
you have a reptile friend, please take some time to find your
pet on Mellisa Kaplan's site, Anapsid.org,
and give us a call with any questions. Don't cut corners when
it comes to husbandry.
