Abstract


Keywords:
Lizards, Parasites, SEM, Mizoram, India.

This study revealed the parasitic fauna of different species of lizards from different parts of Mizoram, India. Four different species of lizards, namely House lizard (Hemidactylus flaviviridis, Gekkonidae), Monitor lizard (Varanus indicus, Varanidae), Gecko (Gekko gecko, Gekkonidae) and Chameleon (Chamaeleo zeylanicus, Chameleonidae) were surveyed from different parts of Mizoram, India in an attempt to investigate the prevalence of parasites. Faecal samples were examined by conventional sedimentation and floatation techniques. Lizards that were run over by car or sacrificed underwent post-mortem examination. Blood samples were also examined for the presence of any haemoprotozoan infection. Light microscopy (LM) and scanning electron microscopy (SEM) were applied for detailed morphological study. The ecto-parasites were identified on the basis of morphology. A total of 69 lizards were examined and found to be infected with three species of nematode (Pharyngodon sp., Rhabdias sp. and Stongyle), one species of trematode (Postorchigenes sp.), three species of tissue protozoa (Eimeria spp., Isospora spp. and Cyclospora spp.) and two species of hamoprotozoa (Trypanosoma sp. and Lankesterella sp.). Only one species of tick belonging to the genus Amblyomma was found on the body surface of monitor lizard. The study clearly indicates that lizards can harbour different parasites which can affect the health status of these reptiles.
