The suppressive performance of soil amendments with three commercial formulations of defatted seed meal from <italic>Brassica carinata</italic>, dry biomass of <italic>Medicago sativa</italic> and pressed pulp from <italic>Beta vulgaris</italic> was comparatively evaluated on the root knot nematode <italic>Meloidogyne incognita</italic> both on potted and field tomato (cv. Regina) trials. Products were applied at rates of 10, 20, 30 or 40 g/kg and 20 and 40 T/ ha soil in pots and field, respectively. Soil non treated or treated with the nematicide Oxamyl were used as controls in both experiments. Amendments in potted soil significantly reduced <italic>M. incognita</italic> infestation on tomato roots compared to both the untreated control and treatment with Oxamyl, also increasing tomato plant growth up to the 30 g/kg soil rate. At the end of the field tomato crop, soil population density of <italic>M. incognita</italic> resulted significantly reduced by all the tested treatments, whereas tomato yield was significantly higher than the untreated control only at the lowest amendment rate. Soil amendments with the materials tested in this study demonstrated to be a potential additional tool for a satisfactory and safe management of root-knot nematodes.</p></abstract>ARTICLE2020-11-19T00:00:00.000+00:00Metazoan parasite communities of three endemic cichlid fish species from the upper Grijalva River, Chiapas, Mexicohttps://sciendo.com/article/10.2478/helm-2020-0041<abstract> <title style='display:none'>Summary</title> <p>We recorded the metazoan parasite communities in three endemic cichlids (<italic>Chiapaheros grammodes</italic>, <italic>Vieja breidohri</italic> and <italic>V</italic>. <italic>hartwegi</italic>) collected between November 2008 and July 2009 in the upper Grijalva River Basin (GRB), Chiapas, Mexico. In total, 6,287 individual parasites belonging to 18 taxa (1 monogenean, 6 digeneans, 1 cestode, 4 nematodes, 2 acanthocephalans, 1 hirudinean, 2 copepods and 1 pentastomid) were found. Eleven metazoans were adult forms and 7 larvae; moreover, 14 were endoparasites and 4 ectoparasites. Sixteen parasite taxa represent new geographical and host records. The helminth community in the three cichlids was characterized by higher number of generalists than specialists, as well as a higher proportion of autogenics than allogenics. The metazoan parasites showed prevalence and mean abundances moderate to high. The infracommunities and component community of metazoan parasites had low diversity, richness, and number of individuals and are similar to those reported for other cichlids in Southeastern Mexico, characterized by the presence of typical parasites of cichlids, with a high number of digeneans and generalist parasites. We report the introduced Asian parasitic copepod <italic>Neoergasilus japonicus</italic> parasitizing endangered or threatened endemic cichlids in the upper GRB. This copepod have been widespread in other freshwater fish species, mainly in Asia (China, India, Japan, Russia, Taiwan), Europe (France, Hungary, Italy, Turkey), and America (Cuba, Mexico, Peru, United States).</p></abstract>ARTICLE2020-11-19T00:00:00.000+00:00Clinical-parasitological screening for respiratory capillariosis in cats in urban environmentshttps://sciendo.com/article/10.2478/helm-2020-0046<abstract> <title style='display:none'>Summary</title> <p>Respiratory capillariosis is a widely distributed zoonotic parasitic disease caused by the nematode <italic>Capillaria aerophila</italic> (Trichocephalida, Trichuridae) that commonly infects wild carnivores but also cats and dogs. This retrospective study aims to describe cases of respiratory capillariosis in cats from the city of Belgrade, Serbia. Between 2015 and 2019, a total of 155 pet cats with or without respiratory symptoms were submitted to physical examination and parasitological examination of the feces. All cats lived indoor but had free access to outdoor. In suburban settlements, wild carnivores commonly share their living environments with owned cats and dogs. It can be assumed that more intense urbanization spreading into the natural habitats of will carnivores creates the opportunity for closer and more frequent contacts between the population of cats and feral carnivores which might increase the risk of feline contamination. The findings confirm the existence of capillaries in cats in urban areas of the city of Belgrade, contribute to a better understanding of the epidemiology of this nematode and warn that, because of close contacts between cats of pets and humans, capillaries can cause human infection.</p></abstract>ARTICLE2020-11-19T00:00:00.000+00:00Vertical distribution of soil free-living nematode in a playa habitat in the North-Western Negev desert, Israelhttps://sciendo.com/article/10.2478/helm-2020-0043<abstract> <title style='display:none'>Summary</title> <p>In order to investigate the vertical distribution of soil nematode community under a playa area in the Nizzana inter-sand dune area in the north-western Negev Desert of Israel, soil samples were collected from 0 – 10, 10 – 20, 20 – 30, 30 – 40, and 40 – 50 cm depths in the playa and loessial plain area (as control) during the dry and wet seasons. Each of soil samples was determined for soil moisture, organic matter concentration, electrical conductivity, and nematode community structure and biodiversity. The results revealed that soil moisture, organic matter, electrical conductivity, total nematode abundance and trophic groups were significantly influenced by sampling positions (<italic>P</italic> &lt; 0.0001) and depths (<italic>P</italic> &lt; 0.05) and significant interaction effect of position and depth (<italic>P</italic> &lt; 0.05) was also found. Total number of nematodes in the playa area ranged from 1 to 15 individuals per 100 g dry soil, whereas they ranged from 60 to 631 individuals per 100 g dry soil in the loessial plain area. The greatest nematode number was found in 0 – 10 cm soil depth and the lowest nematode number was found in 40 – 50 cm soil depth. Total number of nematodes, bacterivores, fungivores, plant parasites and omnivores-predators were significantly (<italic>P</italic> &lt; 0.05) greater in the loessial plain area than that in the playa area in all sampling depths under the dry and wet seasons. Total thirteen genera were found in the playa area, with <italic>Acrobeloides</italic> as the dominant genus, whereas there were fifty-five genera, with <italic>Acrobeles</italic> as the dominant genus in the loessial plain area. Nematode ecological indices, such as fungivores/bacterivores ratio (F/B), nematode channel ratio (NCR), trophic diversity (T), Shannon Index (H’), genus dominance (λ), species richness (SR), maturity index (MI), modified maturity index (MMI), Enrichment Index (EI) and Structure Index (SI) were significantly (<italic>P</italic> &lt; 0.01) differentiated between sampling locations. As conclusion, soil free-living nematode inhabited mostly the upper soil layers (0 – 20 cm) and the number of nematode had gradually decreasing trend with soil depths increasing in the playa area. Moreover, each soil layer had a little nematode abundance and community diversity in the playa area in contrast to loessial plain area during the dry and wet seasons. Sampling sites and depths significantly effected on soil properties, nematode abundance and trophic groups, but nematode ecological indices were affected only by sampling sites.</p></abstract>ARTICLE2020-11-19T00:00:00.000+00:00Helminth parasites and diet of (Steindachner, 1864) (Anura: Leptodactylidae) from Amapá state, Eastern Amazon, Brazilhttps://sciendo.com/article/10.2478/helm-2020-0044<abstract> <title style='display:none'>Summary</title> <p><italic>Leptodactylus petersii</italic> is a species of anuran found in both terrestrial and aquatic habitats and occurs from South America to southern North America and the West Indies.

This study investigated the larval migration of <italic>Baylisascaris potosis</italic>, the roundworm of kinkajou (<italic>Potos flavus</italic>), in chickens and the associated clinical manifestations of the host. Thirty-six 3-week-old chickens divided into 6 groups were orally inoculated with 3,000 <italic>B. potosis</italic> eggs/chick. Each group of chicken was necropsied at days 1, 2, 3, 7, 30 and 90 PI (post inoculation), and the number of larvae in various organs were counted until day 90 PI. No clinical signs were observed in chickens during the study. Larvae were detected from the liver, lungs or breast-muscles of 13/36 (36.1%) chickens. The mean total number of larvae in the liver, lungs and breast-muscles at days 1, 2, 3, 7, 30 and 90 PI were 0.34, 0.17, 1.66, 1.01, 0.17 and 0, respectively. No larvae were found in the brain, eyes, hid-limb muscles, heart, kidneys and spleen. Although infectivity of larvae in egg-inoculated chickens was low, the present study demonstrated that <italic>B. potosis</italic> larvae can migrate in chickens tissues up to day 30 PI. The result suggests that chickens can serve as a paratenic host for <italic>B. potosis</italic> and may underline a public health importance of <italic>B. potosis</italic> infection as a potential foodborne disease in humans.</p></abstract>ARTICLE2020-11-19T00:00:00.000+00:00Coprological survey of protostrongylid infections in antelopes from Souss-Massa National Park (Morocco)https://sciendo.com/article/10.2478/helm-2020-0045<abstract> <title style='display:none'>Summary</title> <p>Protostrongylids, small nematode lungworms, are an integral part of the wild ruminant helminth community, which can damage animals’ health when they are held in captivity or semi-captive conditions.

It is prevalent among children in the tropics and subtropics, particularly in rural poor communities where sanitation is inadequate or lacking. This cross-sectional study aims to determine the prevalence and significant risk factors of <italic>H. nana</italic> infection among children in rural Yemen. Faecal samples were collected from 498 children and screened for intestinal parasites by using wet mount, formalin-ether concentration and Kato–Katz techniques. A pretested questionnaire was used to collect demographic, socioeconomic, housing condition, and personal hygiene information. Overall, 77.5 % (386/498) of the children were found to be infected by at least one intestinal parasite species. The overall prevalence of <italic>H. nana</italic> was 17.5 % (87/498). Multivariate analysis confirmed that an age of &lt; 6 years (adjusted odds ratio [AOR] = 4.28; 95 % (confidence interval [CI] = 2.04, 8.98), presence of other family members infected with <italic>H. nana</italic> (AOR = 2.48; 95 % CI = 1.45, 4.24), living in the highlands (AOR = 2.87; 95 % CI = 1.56, 5.26), living in a house without improved toilet facilities (AOR = 2.19; 95 % CI = 1.23, 3.88), not washing vegetables before consumption (AOR = 2.11; 95 % CI = 1.06, 4.19), and not washing hands after defecation (AOR = 1.88; 95 % CI = 1.08, 3.27) were the key factors significantly associated with <italic>H. nana</italic> infection among the studied children. In conclusion, <italic>H. nana</italic> is prevalent among children in rural Yemen, particularly among preschool-aged children. Thus, an integrated and effective programme to control intestinal parasitic infections should include preschool-aged children. Such a programme should focus on providing health education on hygienic practices, providing adequate sanitation and improved sources of drinking water, and screening and treating other infected family members.</p></abstract>ARTICLE2020-11-19T00:00:00.000+00:00The effects of seasonality and group size on fecal egg counts in wild Przewalski’s horses (, Poljakov, 1881) in the Chernobyl Exclusion Zone, Ukraine during 2014 – 2018https://sciendo.com/article/10.2478/helm-2020-0042<abstract> <title style='display:none'>Summary</title> <p>The aim of this study was to investigate the difference in Fecal Egg Counts (FEC) with regard to group size, age, sex and body condition of wild free-roaming Przewalski’s horses in the Chernobyl Exclusion Zone (Ukraine), across different seasons, over a five-year period (2014 – 2018). We hypothesized that horses from larger group sizes would have higher faecal egg counts (FECs).

Human toxocarosis is a soil-transmitted zoonosis, which may result in partial or general pathological changes in host tissues. We reported a case of 14-year-old boy presented with severe dry cough without dyspnea, mild chest and abdominal pain with general fatigue. Examination of peripheral blood showed marked increase in eosinophils. The chest radiography showed an infiltrative shadow in the lung fields. Chest CT demonstrated multiple opacities in both lungs. Abdominal CT showed multiple low attenuation areas in the liver. Ultrasound guided liver biopsy revealed granulomas with severe eosinophilic infiltration. The boy was treated with albendazole and responded radically. It is worth mentioning that this is the first case of hepato-pulmonary VLM syndrome in Egypt.</p></abstract>ARTICLE2016-08-09T00:00:00.000+00:00Characterisation of (Nematoda: Trichodoridae) associated with potato from the Czech Republichttps://sciendo.com/article/10.1515/helmin-2016-0041<abstract><title style='display:none'>Summary</title><p><italic>Trichodorus similis</italic> associated with potato in the Czech Republic was described and illustrated.

The knowledge on morphological variability and genetic diversity is extended, and a rapid and accurate molecular diagnostics was successfully applied.</p></abstract>ARTICLE2016-11-21T00:00:00.000+00:00Cardiorespiratory and gastrointestinal parasites of dogs in north-west Italyhttps://sciendo.com/article/10.1515/helmin-2016-0032<abstract><title style='display:none'>Summary</title><p>The present study was conducted to evaluate the prevalence of gastrointestinal and cardio-respiratory parasites in dogs in Liguria (northwest Italy) which is a region that has scarcely been studied. A total of 450 dogs (260 males and 190 females) were enrolled in the study from 2009 and 2013. All dogs lived in a rural or semi-rural environment in the provinces of Imperia (n = 352) or Savona (n = 98), Liguria. Coprological examinations showed that 197 dogs (43.8 %, CI 38.7-48.9 %) were infected by parasites. Specifically, 3.3 % of the dogs presented only cardio-respiratory species, 32.4 % only intestinal species, and 8.0 % presented a mixed infection.</p><p>The most frequent intestinal parasites were <italic>Toxocara canis</italic> (20 %), <italic>Trichuris vulpis</italic> (17.8 %), Ancylostomatidae (12 %), Coccidia (2.7 %), <italic>Aonchotheca putorii</italic> (1.8 %) and <italic>Toxascaris leonina</italic> (1.8 %). The cardio-respiratory species found were <italic>Eucoleus aerophilus</italic> (9.6 %), <italic>Eucoleus boehmi</italic> (1.6 %), <italic>Angiostrongylus vasorum</italic> (0.7 %), and <italic>Crenosoma vulpis</italic> (0.2 %). A total of 116 dogs (25.8 %) were parasitized by a single species, multiple infections were observed in 81 dogs (18.0 %) up to a six-order infection.</p><p>This preliminary study highlighted that the prevalence of intestinal parasites in investigated area is high. Cardio respiratory parasites were detected in an area that has not been investigated before. The creation of a more extensive sampling programme of the area, on a provincial basis in order to build a more detailed map of prevalences for different species of dog parasites throughout Liguria, a more extensive sampling programme of the area needs to be created - ideally for each province.</p></abstract>ARTICLE2016-08-10T00:00:00.000+00:00Parasites of edible land snails in Edo State, Nigeriahttps://sciendo.com/article/10.1515/helmin-2016-0031<abstract><title style='display:none'>Summary</title><p>Land snails are sources of protein to man and are hosts to a number of parasites. It is imperative that the roles of the snail hosts and parasites are clearly defined. Before then however, the parasites of the different land snails collected in any locality should be identified. Land snails were collected in the wild in both dry and wet seasons. The internal organs and the faeces were examined for the presence of parasite. In the rainy season of 2015, a total of 272 snails were collected across four major towns (Benin, Uromi, Ekpoma and Auchi) in Edo State, Nigeria, while in the dry season, fewer snails (n=91) were handpicked. The snail species seen are: <italic>Achatina achatina</italic> (Linnaeus, 1758), <italic>Achatina fulica</italic> (Férussac, 1821), <italic>Acharchatina marginata</italic> (Swainson, 1982), <italic>Limicolaria aurora</italic> (Jay, 1839), <italic>L. flammea</italic> (Müller, 1774) and <italic>Limicolariopsis</italic> spp. The larvae of <italic>Strongyloides stercoralis</italic> were isolated from the various snail species with overall prevalence of 54.04 %. Snails positive with <italic>Alaria</italic> mesocercariae were <italic>L. aurora, L. flammea</italic> and <italic>Limicolariopsis</italic> spp. Additionally, few <italic>L. flammea</italic> were positive of the cercariae of <italic>Drocoelium dedriticum</italic>. Meanwhile, some samples of <italic>A. fulica</italic> harboured larvae of <italic>Angiostrongylus cantonesis</italic>, sporocysts of <italic>Fasciola gigantica</italic> and <italic>Schistosoma mansoni</italic>. Therefore, these edible snails could pose serious health hazard to man and animals by serving as a possible alternative parasite transmission route.</p></abstract>ARTICLE2016-08-10T00:00:00.000+00:00en-us-1
