This study aimed to identify gastrointestinal parasites in camels (Camelus dromaderius) in the Laghouat region (southern Algeria). The study was carried out over a 5-month period on a total of 100 dromedaries. Dung samples were analysed using different methods such as flotation, sedimentation, and Ziehel-Neelsen staining for research of the cryptosporidiosis. Data showed an overall infestation rate of 78%, with the presence of the following parasites: Cryptosporidium sp. (60%), Nematodes: Nematodirussp (23%), Strongyloides sp. (4%), Marshallagia sp. (2%), and Cooperiasp (3%), different protozoaires: Eimeria sp. (20%), Neobalantidium sp. (2%), and Balantidium coli, cestodes (6%), Moniezia sp. (3%), Multicips sp. (2%), Diphillobothrium sp. (1%), and trematodes: Fasciola hépatica (4%) and Paramphistomum sp (1%). The results showed a significant influence of study site on the parasitic infestation rate (P=0.039). Other factors (sex, age and clinical aspect) had no significant influence. To conclude, gastrointestinal parasites are a major problem of indigenous camels under traditional husbandry. Therefore, parasite control programmes are recommended to increase the productivity of this useful animal.

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. (36.5%), Fasciola sp. (19.2%), stomach worm (3.9%), Ascaris sp. (1.9%) and Strongyloides sp. (1.9%). Overall prevalence of mixed infection was 42.3%. Mixed infection was observed in the animals such as Butani cattle (Balantidium coli and Paramphistomum sp.), Giraffe (Balantidium coli and Paramphistomum sp.), Spotted deer (Balantidium coli, Paramphistomum sp. and Fasciola sp.), Sambar deer (Balantidium coli and Fasciola sp.), Horse (Balantidium coli and Ascaris sp.), Greater kudu (Balantidium coli and Paramphistomum sp.), Nil gai (Balantidium coli and stomach worm), Black wilde beast (Balantidium coli and Paramphistomum sp.), Impala (Balantidium coli and Strongyloides sp.), Hippopotamus (Balantidium coli and Paramphistomum sp.), Zebra (Balantidium coli and Paramphistomum sp.), Wilde beast (Balantidium coli and Paramphistomum sp.; Balantidium coli and Paramphistomum sp. and Fasciola sp.), One Horned Rhinoceros (Balantidium coli and Paramphistomum sp.), Common Eland (Balantidium coli and Paramphistomum sp.), Oryx (Balantidium coli and stomach worm). Diameter of ova or cyst was also measured. Egg per gram/ Cyst per gram of feces (EPG/ CPG) were ranged from 300-1200. Gastrointestinal parasites are highly prevalent in herbivores of Dhaka zoo. Strategic control measure is necessary to protect the endangered species from parasitic infestation. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21245 J. Bangladesh Agril.

This study was carried out in order to identify the different parasites (ecto and mesoparasites) infesting the tortoise Testudo graeca graeca. For this, a population of 24 tortoises was studied from mid-March to May 2018, in the region of Aflou-Laghouat, within two sites: Djellel and Oued Sebgag. The turtles were captured at the time of their activity; sex, age, body weight, total length of the shell and body height were determined. A careful search for parasites has been carried out using various recommended techniques. A total of 126 Hyalomma aegyptium ticks were identified, with an overall prevalence of 71%, an average intensity of 7.4 and an abundance of 5 ticks per individual. The stool examination identified six mesoparasites, namely: Angusticaecum holopterum, Enterobius vermicularis, Strongylus sp, Nematodirus sp, Trichostrongylus sp, Fasciola hepatica. The sex of the host showed a significant influence on the parasitic infestation: the females were four times more infested than the males.

Age Structured Model

SummaryEpidemiological modelling can be a useful tool for the evaluation of parasite control strategies. An age-structured epidemiological model of intestinal helminth dynamics is developed. This model includes the explicit representation of changing worm distributions between hosts as a result of treatment, and estimates the morbidity due to heavy infections. The model is used to evaluate the effectiveness of different programmes of age-targeted community chemotherapy in reducing the amount of morbidity due to helminth infection. The magnitude of age-related heterogeneities is found to be very important in determining the results of age-targeted treatment programmes. The model was verified using field data from control programmes for Ascaris lumbricoides and Trichuris trichiura, and was found to provide accurate predictions of prevalence and mean intensities of infection during and following different control regimes.

Abstract Gastrointestinal parasites represent an important cause of reduced productivity of sheep worldwide. As anthelmintic are still the main control tool for these parasites, this work evaluated the efficacy of commercially available active principles in 22 sheep flocks in the southern region of Rio Grande do Sul, Brazil. In each farm 10 sheep were randomly distributed in seven groups with the following treatments: abamectin; albendazole; closantel; levamisole; monepantel; trichlorphon and no anthelmintic (control). All flocks showed resistance to at least three anthelmintics and in 20 farms only two products demonstrated efficacy for parasitic control. In two farms, there was no susceptibility to the six active principles tested. The results of this study provide evidence that the common commercially available anthelmintic are not assuring effective chemical control of gastrointestinal parasitic infections in ovine flocks in the southern region of Rio Grande do Sul. Monepantel, the newest introduced drug in the Brazilian market was not effective in 18% of the flocks tested, confirming that the parasitic resistance can be established quickly after the introduction of new molecules mainly when alternative program of parasite control is not performed.

Infectious disease which caused by parasite is the most serious problem in tortoise breeding. This study identifies gastrointestinal endoparasites infection on Red Foot (Chelonoidis carbonaria) during November 2020 to February 2021 in Surabaya City. Fecal samples from a tortoise, a total of 14 tortoises were collected and examined by native, sedimentation and floatation methods for parasitic eggs and oocyst. Fecal samples for this research were collected from breeding farm in Surabaya City. Data obtained from this study were presented descriptively and analyzed by Chi-Square test. Based on examination results, the occurrence of gastrointestinal endoparasite infection on Red foot was recorded at 100% from the total samples. The gastrointestinal parasites were identified as helminths and protozoa namely which is dominately by Tachygonetria spp. (14%), Angusticaecum spp. (3%), and Balantidium coli (2%) respectively. The provision of deworming medication as a curative measure by the owner is carried out regularly and continuously on tortoises that are positively infected with gastrointestinal endoparasites and prevention can be done by paying attention to the management and cleanliness of the cage to prevent potential transmission of endoparasites from the environment to the tortoise.

Abstract Helminth and protozoan infections are responsible for important diseases in grazing sheep, which can be especially threatening in an autochthonous breed at risk of extinction like the Churra Galega Mirandesa Portuguese sheep breed. The aim of the present study was to determine the diversity, prevalence and burden of gastrointestinal parasites in these sheep and to assess the effects of deworming practices, cohabiting animals on the farm and feed management. Coprological qualitative and quantitative analysis (flotation, natural sedimentation and McMaster method) were used to identify and quantify gastrointestinal parasites and a questionnaire was designed and applied. A total of 512 faecal samples were collected from 49 flocks, and 49 replies to the questionnaire were received. Parasites were identified in 100% of the flocks, and in 97% of the samples. The genera or species that have been morphologically identified were: strongyle-type, Nematodirus spp., Skrjabinema spp., Moniezia expansa, Moniezia benedeni, Trichuris spp., Capillaria spp., Eimeria spp., Dicrocoelium spp. and Fasciola hepatica. This is the first report in Portugal of Skrjabinema spp. The burden of parasites’ oocysts and eggs per gram in faecal samples ranged, respectively, from 50 to 17,550 for Eimeria spp., and from 50 to 6250 for strongyle-type eggs. Factors affecting parasitic infections were evaluated using a multivariate logistic regression. Grazing time and a lack of anthelmintic treatment were positively associated with Nematodirus spp. infection. This study showed that there is a high prevalence and diversity of gastrointestinal parasites in the Churra Galega Mirandesa sheep breed.

AbstractBiological control has been an important tactic in the management of Canadian forests for over a century, but one that has had varied success. Here, we review the history of biological control programmes using vertebrate and invertebrate parasitoids and predators against insects in Canadian forests. Since roughly 1882, 41 insect species have been the target of biological control, with approximately equal numbers of both native and non-native species targeted. A total of 161 species of biological control agents have been released in Canadian forests, spanning most major orders of insects, as well as mites and mammals. Biological control has resulted in the successful suppression of nine pest species, and aided in the control of an additional six species. In this review, we outline the chronological history of major projects across Canadian forests, focussing on those that have had significant influence for the development of biological control. The historical data clearly illustrate a rise and fall in the use of biological control as a tactic for managing forest pests, from its dominance in the 1940s and 1950s to its current low level. The strategic implementation of these biological control programmes, their degree of success, and the challenges faced are discussed, along with the discipline’s shifting relationship to basic science and the environmental viewpoints surrounding its use.

SUMMARYVector systematics research is being transformed by the recent development of theoretical, experimental and analytical methods, as well as conceptual insights into speciation and reconstruction of evolutionary history. We review this progress using examples from the mosquito genusAnopheles. The conclusion is that recent progress, particularly in the development of better tools for understanding evolutionary history, makes systematics much more informative for vector control purposes, and has increasing potential to inform and improve targeted vector control programmes.

AbstractEfficient control of gastrointestinal parasites is necessary in sheep breeding. However, the available chemically based anthelmintics are becoming less effective due to the development of parasite resistance. An alternative to this problem is biological control. In the present study, we tested the larvicidal effect of Bacillus circulans by administering a spore suspension (2 × 109 colony forming units/ml) orally to lambs naturally infected with Haemonchus contortus. The number of faecal larvae was quantified daily and a significant reduction (~87%, P< 0.05) of larval development was observed after administration of B. circulans. Using a transformed B. circulans with green fluorescent protein, we were able to detect B. circulans in the faeces at 4 h post-administration and 72 h after cessation of its administration. These results suggest the use of B. circulans as a promising biological alternative for parasite control.
