Summary
This study reports the first occurrence of Kalicephalus sp. hookworms in a Russell
Area of Science:
- Veterinary Parasitology
- Herpetology
- Helminthology
Background:
- Russell's vipers (Daboia russelii) are venomous snakes found in South Asia.
- Gastrointestinal parasites, including hookworms, can affect snake health and survival.
- Accurate identification of parasites is crucial for effective treatment and management in captive reptiles.
Purpose of the Study:
- To document the presence and morphological characteristics of Kalicephalus sp. hookworms in a Russell's viper.
- To provide detailed morphological descriptions of the identified helminths.
Main Methods:
- Necropsy of a Russell's viper housed in Chennai Snake Park.
- Gross examination of the stomach and intestinal contents.
- Microscopic examination of recovered helminths for morphological identification.
Main Results:
- Kalicephalus sp. hookworms were identified in the stomach and intestine of the Russell's viper.
- Morphological features included a cylindrical, thread-like body, bivalvular buccal capsule, muscularised oesophagus with a rounded bulb.
- Male worms exhibited a trilobed bursa with short, equal spicules; strongyle-type eggs were observed.
Conclusions:
- This report represents the first documented instance of Kalicephalus sp. infection in a Russell's viper in Chennai.
- The findings highlight the importance of regular parasitic screening in captive snakes.
- Understanding helminth infections in snakes is vital for conservation and veterinary care.
