ABSTRACT
A four months old Red Eared turtle was brought to the Avian and Exotic Pet Unit (AEPU), Madras Veterinary College
with a history of some irregular dark spots on the dorsal aspect of shell (carapace). After proper restraint, physical
examination was carried. Whitish spots were observed on carapace. The shell was free from crack and wound. It was
reported that these spots started to spread across its shell. But, the turtle had normal appetite and was fed with commercial
turtle feed. Swabs were collected from the carapace and water from the terrarium, for the identification of infectious agent.
Culture and antibiotic sensitivity test were done for the formulating the therapeutic protocol. Both the samples were
positive for Staphylococcus spp infection. The turtle was managed with the amikacin and metronidazole oral suspension
and the treatment was continued for ten days. Superficial lesion was daily cleaned with diluted povidone iodine for 14
days. After 14 days, the turtle recovered from the clinical condition.
KEY WORDS: Red Eared turtle, Shell rot, Staphylococcus spp
INTRODUCTION
In recent years, reptiles esp. turtles have become
increasingly popular as pets. Dermatological problem
commonly arises in captive turtle due to improper care and
management and lack of knowledge related to their
housing pattern. High humidity, low temperatures, poor
nutrition, an under-floor heater, and injured skin are all
potential factors in the development of Testudine bacterial
infections. Gram-negative bacteria that are normally
present in the environment are the most common cause of
bacterial infection.
Clinical History and Observation
A four months old Red Eared turtle was brought to the
Avian and Exotic Pet Unit (AEPU), Madras Veterinary
College with a history of some irregular dark spots on the
dorsal aspect of shell (carapace). After proper restraint,
physical examination was carried. Whitish spots were
observed on carapace. The shell was free from crack and
wound. It was reported that these spots started to spread
across its shell. But, the turtle had normal appetite and was
fed with commercial turtle feed. Swabs were collected
from the carapace and water from the terrarium, for the
identification of infectious agent.
White spot were observed on carapace
Diagnosis
Culture and antibiotic sensitivity test were done for the formulating the therapeutic protocol. The samples collected were
positive for Staphylococcus spp infection.

Treatment
The turtle was managed with amikacin I/M and the
metronidazole oral suspension and treatment was
continued for ten days. Superficial lesion is daily cleaned
with diluted povidone iodine for 14 days. After 14 days,
the turtle recovered from the clinical condition.
DISCUSSION
Traumatic injuries such as bites from other turtles or
predators can penetrate the outer keratin layer of the shell.
Burns and bacterial or fungal infections can also lead to
ulcers on the shell rot (Mader, 2006). Clinical findings
such as soft spot of the shell and hyperemia on the turtle
carapace are in accordance with findings of Fowler et al.
(2008) who stated that the shell rot infection caused soft
spot on the shell, hyperemia, fibrin deposits, cutaneous
ulceration, sloughing of skin, septicemia and dehydration.
The lesions in this case were found on the dorsal part of
the shell (Carapace). This was in accordance with Fowler
et al (2008) who quoted that, the initial stages of infection
caused soft spot on the shell and later it cause cutaneous
ulceration and fibrin deposit on the shell. Similarly,
Harvey-Clark (1995) reported that gram positive cocci and
candida were isolated from skin and foot lesions of turtles.
Usage of amikacin at the dose rate of 3mg per kg body
weight and the metronidazole treatment of shell rot was
for at the dose rate of 50 mg per kg body weight against
the bacterial infection based on the carpenter (2012). The
therapeutic effect was observed, which revealed a marked
clinical improvement with regard to improvement in shell
texture and appearance. Hoppmann (2007) recommended
the treatment of superficial cases with 2% chlorhexidine or
povidone-iodine solution, twice daily soaks, until lesions
resolved.
CONCLUSION
Shell rot is a common fungal or bacterial infection of a
Turtle or Tortoise shell, associated with a soft spot on the
shell hyperemia, fibrin deposit, cutaneous ulceration,
Sloughing of skin, Septicemia, dehydration. This wound
leaves room for bacteria or fungi to move in and grow.
The infection will, if left alone can rot through the bone
and into the body cavity. Amikacin and Metronidazole
were used for the treatment of bacterial infection at a dose
rate of 3mg per kg body and 50 mg per kg body weight
against bacterial infection and it gives the best result
against shell rot infection in red eared turtle.
