(Italy) - Veiled Chameleon (Chamaeleo calyptratus)
examined by Michele Buono DVM (Turin, Italy)
female Veiled Chameleon (Chamaeleo calyptratus) was
presented to the veterinary clinic in July 2007 for anorexia
and reluctance to move.
chameleon was housed in a glass terrarium, size 60cm by
100cm by 60cm (24in by 39in by 24in); inside there were
branches for climbing, and a plastic rock waterfall. There
was a UVB fluorescent tube, but this was outside of the
clinical examination, the animal had a severe metabolic
bone disorder (MBD) and x-rays showed a large number of
eggs. (Figure 1.)
was begun with oral calcium borogluconate with dextrose
(ATI) at a dosage of 100mg/kg and oral calcediol
(25-hydroxy-vitamin D3, 1.5mg/10ml) (Didrogyl, Bruno
farmaceutici SpA) at a dosage of 200IU/kg every week.
new ZooMed Reptisun 10.0 Compact Lamp was installed inside
the terrarium and switched on for 12 hours a day. This was
positioned at about 15cm (6in) from the animal.
3 days the chameleon closed its eyes and spent all the day
unmoving on a branch.
owner was advised to replace the lamp with a ZooMed Reptisun
5.0 Compact Lamp and reduce the exposure to 6 hours a day.
this change, the chameleon opened its eyes again and after
15 days of therapy, it began to eat again.
months after first presentation, the chameleon was re-examined.
Its eyes were normal. Its condition had improved; it was
able to walk, although with some deviation of the hind limbs,
and x-rays showed an apparent improvement in bone mineralisation.
