Endoparasites of rodents from the Chittagong Hill Tracts in Southeastern Bangladesh

Abstract

Rodents are a key mammalian group highly successful in adapting to a variety of environments throughout the world and play an important role in many zoonotic cycles. Within this project, the gastrointestinal and extraintestinal parasite fauna of 76 rodents (Muroidea and Sciuridae) was determined in the District of Bandarban (Chittagong Hill Tracts) in Southeastern Bangladesh. Gastrointestinal and extraintestinal parasites were examined with macro- and microscopical tools (e.g. Ziehl-Neelsen Staining) at a field site in Bandarban. A wide variety of parasites were found in rodent hosts, including protozoa-Giardia sp. (n = 8), Cryptosporidium sp. (n = 1), Entamoeba sp. (n = 8), Trichomonadida (n = 4), Isospora sp. (n = 1), trematodes (Echinostoma sp.; n = 3), cestodes-Hymenolepis nana (n = 1), Hymenolepis diminuta (n = 3), Hymenolepis sp. (n = 2), Taenia taeniaeformis-Larven (n = 4), Catenotaenia sp. (n = 1), Taenia sp. (n = 1), nematodes-Heterakis spumosa (n = 4), Heterakis sp. (n = 1), Aspiculuris tetraptera (n = 2), Capillaria hepatica (n = 2), Capillaria sp. (n = 3), Syphacia sp. (n = 2), Strongyloides sp. (n = 10), Trichostrongylus sp. (n = 2) and Trichuris sp. (n = 1)-and acanthocephalans (Moniliformis moniliformis; n = 2). Several of the examined parasites are of zoonotic importance via direct or indirect transmission (e.g. C. hepatica) and may affect humans.

A Review of Strongyloides spp. Environmental Sources Worldwide

“…Studies identified Rattus rattus , Rattus norvegicus , Mus musculus , Dasyprocta , and Hydrochoerus hydrochaeris as carriers of Strongyloides spp. [16,17,18,19,20,21,22]. Sample sizes for rodent-based studies ranged from 10 to 502.…”
