Studies have been made of the effect of the dung beetle, Onthophagus gazella, on the release of strongyle larvae from cattle faeces onto pasture. A series of faecal pats containing parasitic nematode eggs was placed on pasture, and beetles were added to some pats to give three levels of beetle activity, viz. 100 g, 200-250 g, and 500 g of faeces per pair of beetles. These pats were duplicated on irrigated and non-irrigated pasture. In both cases the numbers of strongyle larvae migrating from pats attacked by dung beetles were significantly less than those migrating from control pats containing no dung beetles. Compared with larval recoveries from control pats, the percentage reduction in numbers of larvae migrating from pats on irrigated pasture was 50% for pats of 100 g faeces per pair of beetles, 48 % for pats of 200-250 g faeces per pair, and 84% for pats of 500 g of faeces per pair. The respective figures for pats on nonirrigated pasture were 76, 86, and 93 % reduction in larval numbers. The results indicated that strongyle larvae migrated from faecal material buried by dung beetles, provided soil moisture was adequate. More larvae were recovered from the pasture surrounding irrigated faecal pats attacked by beetles than from the non-irrigated pats. During warm dry weather, surface faecal debris remaining after beetlc attack appeared to be helminthologically sterile.

Parasitic Burden

Abstract Objective: Catfishes harbour a greater variety and occurrence of larval helminth parasites because they are exposed to more infective helminth larvae in their diet due to their predatory habit which makes them more susceptible to higher parasitic burden. This study was conducted at department of zoology in Post Graduate Campus, Biratnagar, Nepal to determine the prevalence of helminth parasites in the gastrointestinal tract of two species of catfishes i.e Clarias gariepinus and Heteropneustes fossilis collected from the different water resources of Biratnagar, Eastern Nepal.Results: Out of 280 fish examination, 264 (94.28%) fishes were found to be infected with helminths parasites. Clarias gariepinus infection rate was 84.0% with three species of parasites, one each of nematode i.e. Procamallanus laevionchus, cestode i.e. Proteocephalus species, and trematode i.e. Allocreadium species. Heteropneustes fossilis have prevalence rate of 100% with five species of helminth parasites i.e. two nematode species namely Procamallanus heteropneustes and Eustrongyloides species, one cestode namely Lytocestus indicus, one trematode i.e. Phyllodystomum folium and an acanthocephalan i.e. Pomphorhynchus species were detected.

Abstract The gastrointestinal helminth parasites of 170 common wallaroos or euros, Osphranter robustus (Gould), collected from all mainland states in which the species occurs as well as the Northern Territory, are presented, including previously published data. A total of 65 species of helminths were encountered, including four species of anoplocephalid cestodes found in the bile ducts and small intestine, and 61 species of strongylid nematodes, all but two of which occurring in the stomach, and with the remainder occurring in the terminal ileum, caecum and colon. Among the mainland subspecies of O. robustus, 52 species of helminths were encountered in O. r. robustus, compared with 30 species in O. r. woodwardi and 35 species in O. r. erubescens. Of the parasite species encountered, only 17 were specific to O. robustus, the remaining being shared with sympatric host species. Host-specific species or species occurring in O. robustus at a high prevalence can be classified as follows: widely distributed; restricted to northern Australia; restricted to the northern wallaroo, O. r. woodwardi; found only in the euro, O. r. erubescens; found essentially along the eastern coast of Australia, primarily in O. r. robustus; and species with highly limited regional distributions. The data currently available suggest that the acquisition of a significant number of parasites is due to co-grazing with other macropodids, while subspeciation in wallaroos as well as climatic variables may have influenced the diversification of the parasite fauna.

The prevalence of gastrointestinal helminth infections and the gross pathological lesions produced by them were studied from February 2012 to January 2013 in the Department of Pharmacology of Bangladesh Agricultural University, Mymensingh. In this study, a total of 320 indigenous chickens aged ranging from 2 to 4 months were examined to identify the different types of gastrointestinal helminth infections in indigenous chickens. During routine examination, six species of helminth parasites were recorded, of which five species of nematodes such as Ascaridia galli, Heterakis gallinarum, Capillaria spp, Acuaria hamulosa and Dispharynx spiralis; and one species was cestode called Raillietina tetragona. The highest prevalence was observed for Ascaridia galli (41.56%) followed in descending order by Raillietina tetragona (19.68%), Heterakis gallinarum (15.62%), Acuaria hamulosa (8.75%), Capillaria spp. (4.68% ) and Disopharinx spiralis (1.56%). The gross pathological lesions were observed in case of Acuaria hamulosa and Heterakis gallinarum infection. In case of Acuaria hamulosa infection keratinization of gizzard mucosa and cross section of adult Acuaria hamulosa were seen along with marked infiltration of neutrophils. The results of this study suggest that both nematodes and cestodes are highly prevalent in indigenous chickens in the studied area.DOI: http://dx.doi.org/10.3329/bjvm.v12i2.21275 Bangl. J. Vet. Med.

Abstract Helminth parasites are still not a well-known component of animal biodiversity. In this study, we describe and compare the endoparasite assemblages of three native rodent species from a semiarid Mediterranean ecosystem. A total of eight species of gastrointestinal helminth parasites were detected. The endoparasitic communities of the rodents Phyllotis darwini (5 species), Octodon degus (4 species), and Abrothrix olivaceus (3 species) were described in terms of their prevalence and mean abundance. In addition, endoparasite records by rodent species were submitted to rarefaction analyses to verify sampling robustness and used to compare richness and similarity among rodent species. O. degus presented the highest prevalence and parasitic load, but was of low diversity, while P. darwini presented the highest diversity, but had a low prevalence rate. Conversely, A. olivaceus presented the lowest prevalence and diversity. This study contributes to the existing knowledge of the endoparasitic fauna of rodent species from semiarid Mediterranean zones.
