Occurrence of gastrointestinal parasitic infection in captive Indian elephants (Elephas maximus indicus) at Bannerghatta Biological Park, Karnataka.

The present study was intended to investigate the endoparasites in Indian elephants (Elephas maximus indicus) maintained under captive condition in Bannerghatta Biological Park, Bengaluru. Material and methods: A total of 19 elephant faecal samples were collected and examined for gastrointestinal parasites. The faecal samples were analysed using sedimentation and floatation techniques followed by microscopic identification of parasitic eggs. Results: Out of 19 elephants faecal samples examined, 12 (63.1%) were found positive for gastrointestinal parasites, which included 7 Strongyle ova, 3 Paramphistomum ova, 3 Trichuris ova and 2 coccidian oocysts. There were some mixed infections observed in few samples, where two were positive for both Strongyle and Paramphistomum ova, and one sample was positive for both Strongyle ova and coccidian oocyst. Discussion: Various studies of wildlife parasites can readily provide data on presence or absence of parasitic prevalence. This can help strategising control measures. Conclusions: Studies on parasitic prevalence is vital in monitoring the health and maintenance of elephant population in captivity.
