Abstract
The
current study aims at evaluating the application of ultrasonographic techniques
in chelonians, and to determine their possible clinica l utility. The study was conducted at
the Tiger and Lion Safari, Tyavarekoppa in Shivamogga and Sri Chamarajendra Zoological
Gardens, Mysuru.
Anatomical
features such as the body weight, carapace length, carapace width,
height and chest girth of the chelonians (n 19) were studied and classified based on
morphometric characteristics. The four species studied incl ude the Indian Black Pond
Terrapin (n 11), the Indian Flapshell Turtle (n 2), the Indian Star Tortoise (n 4) and
the Red eared Slider Terrapin (n 2).
The
chelonians were restrained in ventral recumbency for the procedure and
ultrasound examination was condu cted through the cervico brachial and pre femoral
acoustic windows using a high frequency micro convex probe (6 15 MHz). The location,
size, shape, thickness and echotexture of different coelomic organs like the heart, liver, gall
bladder, gastrointestinal tract, kidneys, urinary bladder and gonads were recorded.
Though
n o pathological changes were ob served during examination, the recorded
data provides a useful standard for comparison to diagnose pathological abnormalities of
the coelomic organs in chelonians.
Detection
of the gonads using sonographic scanning in the Indian Flapshell Turtle
proved a helpful identifier to sex specimens in individuals which display no sexual
dimorphic characters.
