Investigation of gastrointestinal parasites of herbivores at Dhaka National Zoological Garden of Bangladesh

Abstract

A total of 52 fecal samples were collected from 21 herbivores at Dhaka zoo during January to May, 2012 to investigate the prevalence of gastrointestinal parasites of herbivores. Overall prevalence of parasitic infection was 76.9%, of which 61.5% were positive for helminths and 55.8% were positive for protozoa. The identified parasites were Balantidium coli (55.8%), Paramphistomum sp.

Gastro Intestinal Parasites of Musk Deer (Moschus Chryso-Gaster Hodgson, 1839) in Langtang National Park, Nepal

“…Prevalence of Paramphistomum sp. was 44.44% in this study, which was slightly less than the report of Rehman et al (2014) where they showed 36.5% prevalence in 21 herbivore zoo species in Bangladesh. Paramphistomum generally occurs in rumen, reticulum and small intestine and cause intestinal wall erosions, haemorrhage, oedema and necrosis of ruminal papillae (Love & Hutchinson 2003).The infection of Ascaris sp.…”

Parasitisme gastro-intestinal chez les animaux du parc zoologique de Hann au Sénégal

“…Aucune espèce de trématode ou de cestode n'a été identifiée. Rahman et al (2014) au Bangladesh, Opara et al (2010) au Nigeria, et Mir et al (2016) en Inde font le même constat. Ceci est très probablement lié au fait que les trématodes et la majorité des cestodes, à l'exception de Hymenolepis nana, ont besoin d'hôtes intermédiaires, absents des enclos et cages, pour boucler leur cycle évolutif (Atanaskova et al, 2011).…”

THREATENED FISHES OF THE WORLD: Ompok pabda (Hamilton, 1822) (Siluriformes: Siluridae)

“…Several studies on ecology, biology, life history and aquaculture of O. pabda have been conducted (Breder and Rosen, 1966;Rahman, 1989;Menon, 1999;Kohinoor et al, 2009;Banik et al, 2012).…”

“…This catfish was available in beels, ponds, rivers and inundated fields (Rahman, 1989) as well as streams and lakes (Menon, 1999) but now it is seriously declining in the main streams (IUCN Bangladesh, 2000).…”
