Abstract

This study examined the prevalence of gastrointestinal parasitic infections and pasture contamination, and assessed the body condition of free-ranging wild herbivores (i.e. Chital or Spotted Deer, Sambar and Nilgai) in Van Vihar National Park, Bhopal (Madhya Pradesh). The work was carried out in three distinct seasons (i.e. winter, summer and rainy) for a period of 1 year (2005-06). Faecal samples were collected and screened for the presence of eggs/oocysts/cysts of parasites on the basis of qualitative and quantitative estimation techniques, and the body condition of animals was evaluated on a point scale.

Highlights

  • The present work was planned to study the prevalence of gastrointestinal parasitic infections, assess pasture contamination by infective parasitic stages, judge body condition of free ranging wild herbivores; Chital or Spotted Deer (Axis axis), Sambar (Rusa unicolor) and Nilgai or Blue Bull (Boselaphus tragocamelus) and study general condition and management practices in the Van Vihar National Park, Bhopal

  • Quantitative estimation was done by employing the Modified McMaster egg counting technique to determine nematode eggs/coccidia oocysts per gram (EPG/OPG), and Stoll’s dilution technique to determine fluke eggs per gram (EPG) of faeces (Soulsby 1982)

  • Sambar take to water readily and swim with the body submerged, which might have exposed them to infective stages of parasites leading to higher parasitic prevalence in the species

Summary

JoTT NOTE

The epidemiology of gastrointestinal parasitism and body condition in free-ranging herbivores. A number of factors threaten the existence of wild animals in this country, including wildlife diseases and disorders arising from gastrointestinal parasites. The diagnosis of these parasites can be made by faecal sample examination. The present work was planned to study the prevalence of gastrointestinal parasitic infections, assess pasture contamination by infective parasitic stages, judge body condition of free ranging wild herbivores; Chital or Spotted Deer (Axis axis), Sambar (Rusa unicolor) and Nilgai or Blue Bull (Boselaphus tragocamelus) and study general condition and management practices in the Van Vihar National Park, Bhopal.
