A pool of fish species in a Niger Delta tidal creek, Buguma Creek, Nigeria, collected monthly from November 2004 to June 2006, at flood tides, were examined for gastrointestinal helminth parasites. The fish species were caught with hooks and lines and cast nets. Only nematode parasites were encountered in the study. Of the 1,149 fish specimens examined, 213 (representing 18.5%) were infected with various nematodes parasites. Dasyatis margarita had the highest prevalence rate of 66.7% (2 infected out of 3 examined), followed by Pseudotolithus (Pseudotolithus) senegalensis with a prevalence of 41.7% (10 infected out of 24), while the least infected were Arius gigas and Pomadasys jubelini with prevalence of 3.8% and 1.4%, respectively. No infection was recorded in Elops lacerta, Gobius sp., Lutjanus agennes, L. goreensis, Argyrosomus regius, Sphyraena guachancho, S. sphyraena, Cynoglossus senegalensis, Sarotherodon melanotheron, Tilapia guineensis, Liza falcipinnis, Mugil cephalus, and M. curema. The nematode parasites, Capillaria zederi, and Aplectana hamatospicula had the highest prevalence of 33.3% in D. margarita. Laurotravassoxyuris sp. also had the same prevalence in Trichiurus lepturus. Goezia sigalasi had the second highest prevalence of 12.5% in P. (Fonticulus) elongatus which had the highest number examined, due to its high dominance in the water.

The composition and relative abundance of fish species assemblage of a mangrove creek in the Niger Delta, Nigeria based on different types of gear was assessed at four stations between November 2004 and June 2006. The overall community structure was made up of 25 species of 16 families. Visual observation showed that tilapia species comprising of Sarotherodon melanotheron and Tilapia guineensis were the most dominant species. Samples from baited entrance traps indicated that S. melanotheron dominated T. guineensis. Samples from baited hook and line, and cast net showed dominance of P. elongatus followed by P. quadrifilis. (The baited hook and line is commonly used by the fishers because it is effective in catching diversity of species, except that it is unable to catch bottom feeders such as mullets and tilapia species). Funnel entrance trap had the highest species selectivity, catching only tilapia species. Cast net was more selective in species catch than baited hook and line, but it was effective in catching both pelagic and benthic species. Among the fish species, members of the families: Sciaenidae, Polynemidae, Ariidae, Monodactylidae and Cichlidae were permanent residents; Carangidae, Luthjanidae and Serranidae were temporary residents; while Elopidae, Gobiidae, Dasyatidae, Cynoglossidae, Sphyraenidae and Trichiuridae were rare species.

AbstractEthnomedicine is an integral part of traditional medical practices in many countries of the developing world. A large proportion of the population uses this form of treatment for primary health care and for the treatment of ailments in their livestock. Livestock is a major asset for resource-poor smallholder farmers and pastoralists throughout the world and internal parasites are recognized by these communities as having an impact on livestock health. Parasitic infections are among those infections that traditional healers confidently treat and against which an enormous variety of remedies exist. Many of these are based on the use of plant preparations. Although various methods have been used for the validation of traditional phytomedical preparations, there is a lack of standardization of these procedures. The present study is aimed at providing an overview of ethnoveterinary deworming preparations, the various methods that have been used in their validation and the future prospects for their use against helminth parasites of ruminant livestock in developing countries, with an emphasis on nematode parasites. Recommendations are made on the procedures that should be followed to conduct in vivo and in vitro assays. Fostering better interaction between traditional healers and scientists is advocated to prevent harmful overexploitation, both of local knowledge and of plant species that may have effects against nematode parasites.

Length-weight relationships (LWRs) and condition factor are important biological information to assess the growth pattern and wellbeing of fish species influenced by numerous abiotic and biotic factors. To date, no data on the LWRs and condition of mullets in Sombreior River, Niger Delta. Hence, this research was conducted to determine abundance, length–weight relationship and Fulton’s condition factor (K) of three species of fish belonging to family Mugilidae in Sombreior River, Nigeria. There were a total of 248 samples from five sampling stations for a period of months. Fish species were of various sizes ranging from 24.66±0.40 to 26.35±0.26cm in length and 141.41±6.30 to 161.56±5.87g in weight. For the three species, slope (b) values ranged from 2.18 to 2.68 indicating a negative allometric growth of all fish species. The mean condition factor ranged from 0.89±0.03 forsix Mugil cephalus to 0.93±0.03 for Parachelon grandisquamis while the coefficients of determination (R2) of the LWR regressions ranged between 0.64 (Neochelon falcipinnis) and 0.79 (Parachelon grandisquamis). It was concluded that the mullets in the Sombreior River had a negative allometric growth pattern and the condition is showing the species were in good state of well-being since mean K values are  greater than 1.

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.
