Abstract:
In this study is made an ecological analysis of the species composition, structure of the helminth community and the invasion degree of Ranidae and Bufonidae families in different habitats in Moldova. As a result, it has been established the presence of 17 helminths species. It was found that the diversity of helminth fauna of the studied amphibians is structured depending on the host species, biotop, biotic factors, gender and depending of the host onthogenesis. Thus, the greatest diversity of helminthes in amphibians in the family Ranidae was established in Rana ridibunda and Rana lessonae with 17 species, and for the species from the Bufonidae family, no different values were established, so each host species being infested with 3 species of helminthes.

Abstract:
The paper describes the trophic and parasitic relations interfacing of mass abundant orangeback squid Sthenoteuthis pteropus (OS) in the open waters of the Tropical Atlantic. There are described the data on squid’s food, predator and helminth species compositions and theirs ontogenetic, sex and infraspecific variability, and on the place and role of distinct stages of OS life cycle in the trophic and parasite structures of oceanic communities. The predator-prey size relations are 8–20% absolute squid length. Due to this fact the shifts of the main food groups are taken place in squid ontogenesis and, accordingly, there are changes in helminthes species composition and infection rates. The place and role of squids of different ontogenetic stages in the helminths life cycles is also different. These helminthes are transmitted by oceanic trophic webs. Thereupon there are demonstrated the existence of important differences between various life cycle stages, sexes and infraspecific groups of OS in oceanic tropho-parasitic structure. The working hypothesis on mechanism of coevolution of nektonic squids and their helminthes is formulated on the base of «using» by helminthes a quasi-stable trophic web of the vast oceanic pelagic zone.

Abstract:
Background: Intestinal worm infestation is a global health problem and serious concern for the third world countries. The most common intestinal parasites of helminthes that inhabit in human gut include Nematodes (roundworms) and Platyhelminthes (Cestodes and trematodes) which are wide spread throughout the world. Prevention and control of all parasitic infections including helminthes require research work based on the identification of parasites and associated predisposing factors. Objective: The aim of this study was to determine the prevalence and associated risk factors of intestinal parasitic infections of helminthes among the asymptomatic primary school children at Woldia town, North Wollo Zone North Eastern Ethiopia. Methods: The study design was school based cross sectional study from November 2019 to February 2020. The technique of sampling was simple random sampling method and the sample size was computed based on the formula proposed by single population proportion to include 442 study participants. The method of data collection was laboratory microscopic stool examination using direct wet mount and formol-ether concentration technique and the structured questionnaires about the associated risk factors and sociodemographic factors. Analysis of the data was made manually using the thematic framework method including the descriptive statistics Result: The overall prevalence of intestinal parasitic infections of helminths among the asymptomatic primary school children at woldia town was 96(22.7%). The predominant intestinal parasites of helminthes was Ascaries lumbercoides 40 (9.5%) followed by Trichuris trichiura 18 (4.3%), Hymenolopis nana 13 (3.1%) and Hook worms 10 (2.4%). From the overall prevalence of intestinal parasitic infections of helminthes, 96(22.7%), the results obtained by direct wet mount method was 36(37.5%) while the Formol-ether concentration technique method revealed 60(62.5%). Moreover, the result also showed parasitic infections of helminthes were associated with associated predisposing factors. Concluding remarks and recommendations: In this study the overall prevalence of helminthic infections was relatively lower. However the control and intervention of intestinal helminthic infections requires a constant provision of periodic deworming treatment and regular health educations regarding personal hygiene and environmental sanitations.

Abstract:
Helminthological autopsies of Mustelids from various districts of Pskov, Тver and Smolensk region were carried out. To determine the prevalence rates of the infestation, an extensive invasion index was used. According to the results of helminthological autopsies, a list of detected helminthes is given. For the first time on the study area, 14 species of helminthes were recorded in studied Mustelids. Two of the found species of helminthes parasitize in Mustelids in larval form. The maximum variety of species is observed among the Nematoda class. The data on the number of detected helminth species in Mustelids in certain districts of the Tver, Pskov and Smolensk regions, as well as indicators of the frequency of helminthes were given. The maximum number of helminth species is recorded in Mustelids in the Novosokolnichesky district of the Pskov region. Extensiveness of invasion of all studied species of Mustelids, excluding otter, is 100%. According to the indicators of extensiveness of invasion in the studied Mustelids, Isthmiophora melis, Capillaria mucronata, Capillaria putorii, Filaroides martis are prevalent. The maximum number of species of parasitic worms is recorded in pine marten. The research results indicate the dominant influence of the trophic factor in the formation of the helminth fauna of martens that inhabit the study areas.

Abstract:
SUMMARYHelminthes have the capacity to modulate host immunity, leading to positive interactions with coinfecting microparasites. This phenomenon has been primarily studied during coinfections with a narrow range of geo-helminthes and intracellular microparasites in human populations or under laboratory conditions. Far less is known regarding differences in coinfection dynamics between helminth types, the range of microparasites that might be affected or the overall community-level effects of helminth infections on microparasites in wild systems. Here, we analysed the presence/absence and abundance patterns of enteric parasites in long-tailed macaques (Macaca fascicularis) on the island of Bali, Indonesia, to assess whether naturally occurring helminth infections were associated with increased shedding of the most common intracellular (Cryptosporidiumspp.,Isosporaspp.) and extracellular (Entamoebaspp.,Giardiaspp.) microparasites. We also comparatively assessed the statistical correlations of different helminth taxa with microparasite shedding to determine if there were consistent relationships between the specific helminth taxa and microparasites. Helminth infections were associated with increased shedding of both intracellular and extracellular microparasites. Platyhelminthes repeatedly displayed strong positive correlations with several microparasites; while nematodes did not. Our results indicate that helminthes can influence microparasite community shedding dynamics under wild conditions, but that trends may be driven by a narrow range of helminthes.

Abstract:
This study investigated the gastro-intestinal helminthes present in the capture-held mammals at Ogba Zoological garden comprising a total of twenty-six(26) resident mammals representing thirteen (13) wildlife species, between the period of March and June, 2019. The objectives of this study were to identify the common helminthes present in the zoo mammals, estimate number of positive animal species and investigate the prevalence, abundance and diversity of the gastro intestinal helminthes among the animals. Fecal samples of the animals were collected from the study site and subjected to direct microscopic examination and concentration techniques. Overall, a total of four (4) helminthes parasites’ eggs and cyst were identified; Strongyle spp. (Threadworm), Trichuris trichuria (Whipworm) Ancyclostoma duodenale (Hookworm) and Nematodes’ eggs. A protozoan species (Entamoeba spp) was also detected in the Grey Monkeys. Fourteen (14) (53.84%) of the sampled animals were infected with the gastrointestinal helminthes parasites and eggs. Strongyle spp (30.8%), was the most prevalent gastro intestinal helminth found among the animals used for the study, while 19.2% prevalence of Hookworm (15.4%) of whipworm, (15.4%) of Entamoeba spp and (3.8%) of Nematode eggs were recorded. The gastro-intestinal helminthes were highly distributed among the Mona monkeys and grey monkeys. The Nematode eggs and larvae were isolated in the Donkey. Hookworm was highly spread among the Baboons and also found in the Civet Cat. 46.16% of the examined animals were free from gastrointestinal helminthes infection. No record of parasitic helminthes were found in the Chimpanzee, Patas monkeys, White-throated monkeys, Crested porcupine, horses, Maxwell duiker, lion and Hyena in the study site

Abstract:
Several plants are found to possess potent medicinal and phytochemical compounds used globally for the treatment of diseases and the discovery of new drugs. Plants with anthelmintic properties have attained a great interest due to their usage in treatment of parasitic (helminthic) diseases that cause major economic loss, resulting to reduced livestock production capacity of farmers. The major impediment in the livestock subsector is the increasing problems of development of resistance to synthetic drugs by the helminths and or high cost of commercially produced anthelmintics and their resultant side effects than the treatment efficacy in the host. Helminthosis is a clinical condition that represents one of the commonly encountered and most important diseases in ruminant farming. This clinical condition is aggravated by indiscriminate use of anthelmintics in an attempt to control the infection, thereby causing resistance of the parasitic helminths to synthetic drugs. This has led to the screening of plant extracts for their anthelmintic properties thereby serving as alternative strategies against gastrointestinal parasitic resistance. However, eighty percent of the world populations use natural plant compounds as anthelmintics for treatment of parasitic infections. Hence, the folkloric claims of the anthelmintic properties of plants extracts for the treatment of helminthes is necessarily important and of great interest. Therefore, this review unveils previous pharmacological and preliminary studies on plants as anthelmintics able to reduce helmintic infections and overcoming helminth parasite resistance.

Abstract:
Parasitic helminthes infections take place mostly in regions where exposure to other pathogens is as well prevalent. A parasitic worm infestation may encourage infection with another microbe. There are many hypotheses and evidence for how this is done First, helminths naturally encourage a T-helper cell type 2 (Th2) immune response, relating cytokines for example interleukin IL-4, IL-5 and IL-13. seacond in cooperation Th2 and Treg responses have been proposed to decline the generation of protective Th1 or Th17 immunity against bacterial or viral pathogens. Third helminth-modified intestinal metabolism promotes susceptibility to microbe coinfection. This search summarizes our recent understanding in what way the host’s immune response to infection with various kinds of parasitic worm affect susceptibility to predisposition to infection with further microbes.

Abstract:
La paléoparasitologie est l’étude des restes de parasites préservés dans des échantillons archéologiques et permet de mieux comprendre l’état de santé des populations anciennes et d’obtenir des informations d’ordre anthropologique ou ethnologique, sur les régimes alimentaires ou les conditions d’hygiène au quotidien. Les restes de parasites peuvent être retrouvés sous forme de macro-restes (vers ou larves), d’antigènes, d’ADN ou d’œufs. Cesderniers peuvent être particulièrement bien préservés au cours du temps car ils sont composés en partie de chitine, les rendant résistants aux processus de dégradation. L’observation microscopique de leurs caractéristiques morphologiques et micrométriques permet d’identifier les taxons au niveau du genre ou de la famille. Dans le cadre de cette thèse, plusieurs helminthes gastro-intestinaux, dont les œufs sont fréquemment retrouvés dans des échantillons archéologiques, ont été ciblés par une approche génétique. Il s’agit des vers plats Tæniasaginata, T. solium, T. asiatica, Echinococcus granulosus, E. multilocularis, Diphyllobothriumlatum, D. dendriticum et D. nihonkaiense, des nématodes Trichuris trichiura, Enterobiusvermicularis et Ascaris sp. et des douves Fasciola hepatica, F. gigantica, Dicrocoeliumdendriticum et D. chinensis.La méthode « aMPlex Torrent » permet de détecter, dans un grand nombre d’échantillons archéologiques, une faible quantité d’ADN de parasites. Cette approche combine la spécificité et la sensibilité de la PCR au haut-débit du séquençage de nouvelle génération. Plusieurs vestiges, provenant de périodes et de régions géographiques diverses, ont été analysés. Des résultats génétiques ont été obtenus pour des échantillons aussi anciens que 7200 BP. Nous avons par ailleurs obtenus les premières séquences anciennes de Taenia sp., Diphyllobothriumsp., Echinococcus sp., et les premières séquences européennes d’Enterobius vermicularis. Auvu de ces résultats, notre approche apparait comme étant complémentaire à la microscopie
Palaeoparasitogy, the study of parasite remains from archaeological samples, is adiscipline that can highlight questions about the health status of the ancient populations. It can give important anthropological or ethnological information such as the diet and the hygiene conditions of past societies. The remains can be preserved as macroremains (worms or larvae),antigens, DNA or eggs. Because they are partially made of chitin, eggs of gastrointestinalhelminths resist well over time to the taphonomic degradation process. It is possible to distinguish between different families or genera of parasites by looking at the morphological features of eggs. However, since several taxa share common features, the determination is rarelypossible at the species level. For this thesis, several parasite species for which eggs arecommonly observed in archeological samples have been studied by a genetic approach. Westudied the tapeworms Tænia saginata, T. solium, T. asiatica, Echinococcus granulosus, E.multilocularis, Diphyllobothrium latum, D. dendriticum, and D. nihonkaiense; the nematodesTrichuris trichiura, Enterobius vermicularis, and Ascaris sp.; and the flukes Fasciola hepatica,F. gigantica, Dicrocoelium dendriticum, and D. chinensis.The “aMPlex Torrent” approach has been set up to detect minute amounts of DNA from parasites in multiple archaeological samples. This approach combines the specificity andsensitivity of PCR to the throughput of Next-Generation sequencing. Several samples have been analyzed by this approach. We obtained genetic results for samples as old as 7200 BP and from various geographical and archeological contexts. We obtained the first ancient DNA sequences for Taenia sp., Diphyllobothrium sp., Echinococcus sp. and the first European sequences forEnterobius vermicularis. Genetic analyses and microscopic observations appear to be complementary. Indeed, at least one taxon per sample was detected by one of the two approaches

Abstract:
Apres avoir presente l'orge et le pathogene, nous avons conduit une etude analytique et evolutive des symptomes causes par les deux formes du pathogene (maculata et teres) et montre que leur morphologie differente est en relation avec la localisation du mycelium du parasite. La forme maculata determine des symptomes tres polymorphes susceptibles d'etre confondus avec d'autres pathogenes dont certains ont ete decrits pour la premiere fois en france. Par ailleurs, l'etude biologique fait ressortir que ces deux formes ont les memes exigences a l'egard d'un certain nombre de facteurs abiotiques (t#o, ph, lumiere, humidite) et qu'il n'y a a pas d'antagonisme entre celles-ci. Ces resultats ne sauraient donc expliquer leur importance et leur repartition geographique differentes. Apres avoir precise les facteurs qui concourent a l'optimisation de la biosynthese du complexe toxique, nous avons montre que les phytotoxines sont largement impliquees dans l'expression des composantes du symptome mais qu'elles ne semblent pas responsables du pouvoir pathogene. Ensuite l'etude de la sensibilite des differents cultivars d'orge a la maladie a revele que la plupart de ceux cultives en france sont sensibles a tres sensibles.

Full text
Abstract:
La diversite helminthique des ruminants a ete peu etudiee, surtout dans le cadre d'etudes faunistiques. Seules 5 a 6 especes de nematodes parasitent le tube digestif des bovins en regions temperees. La diversite specifique est estimee sur les vers adultes recoltes apres autopsie et la diversite generique a partir des larves infestantes dans les matieres fecales. Chez les nematodes, tant a large (france, colombie, usa, espagne, zaire, argentine, bresil) qu'a petite echelle (pampas d'argentine) nous avons montre que la diversite etait associee a de faibles intensites. Dans ces etudes nous avons utilises l'indice classique de shannon, de qualite incertaine en l'absence de mesure formelle de sa variabilite. Il y avait necessite de developper des methodes plus efficaces pour differencier des sites ou des fermes. Nous avons developpe une methode fondee sur les resultats d'autopsie parasitaire : une analyse discriminante etait etablie sur les proportions de chaque espece, sur les proportions rangees par ordre decroissant (distribution de ces proportions), et enfin sur une combinaison lineaire de 15 indices univaries (correspondant a une opposition dominance-diversite). Cette technique statistique a ete utilisee ensuite pour apprecier la diversite generique obtenue a partir des larves infestantes obtenues lors de coprocultures. Cette derniere facon de proceder a ete efficace pour differencier les fermes selon leur diversite generique, etait repetable, et nous l'avons choisie comme methode de reference. Une etude a alors ete realisee dans 21 fermes des pampas argentines afin de rechercher les facteurs de variation de la diversite. Sur le modele de la theorie des iles, nous avons recherche si le nombre d'hotes infestes introduits et de traitements anthelminthiques (frequence et type) limitant la survie des nematodes au sein des fermes, etaient des facteur importants du maintien de la diversite. L'augmentation du nombre de traitements reduit fortement la diversite generique. Des recherches complementaires seraient a efectuer en ce qui concerne l'utilisation de la diversite fonctionnelle plutot que de la diversite specifique ou generique.

Abstract:
As a result of long-term studies, it has been identified that the effects of anthropogenic factors on the formation of helminth fauna of domestic carnivores are reflected in a number of changes. Thus, primarily due to the change in habit of animal, the quantitative and qualitative changes have happened in the helminth fauna: new species of helminths which assume epizootic and epidemiological significance has been found and this has significantly enriched the species composition of the helminth fauna. Due to the influence of anthropogenic factors, the mixed parasitic focuses have formed and 14 species of helminths have included in helminth fauna. The domestic carnivores infected with pathogenic helminths from this focus infect human beings, domestic and ruminating animals from sinantropic focus. Thus, due to impact of the anthropogenic factors, the helminth fauna of animals has changed and has acquired its modern helminthological status.

Abstract:
The monitoring results of the helminth fauna of small rodents living on meliorative channel banks in the mixed forests of Western Belarusian Polesie (Brest Polesie) in 2015-2016 are presented. One hundred and seventeen specimens of three rodent species are caught. 72.3 % of red-backed voles and 60.0 % of yellow-necked mice are found infected by helminths. Seventeen helminth species (2 species of trematodes, 7 species of cestodes, 8 species of nematodes) are found. Twelve species of helminths are localized in red-backed voles, and nine species of helminths in yellow-necked mice. The nematode Heligmosomum mixtum Schulz, 1954 dominates in the infestation of red-backed voles, while the cestode Skrjabinotaenia lobata (Baer, 1925) and the nematode Syphacia frederici Roman, 1945 dominates in the infestation of yellow-necked mice. Four species of helminths identified in rodents are of medical and veterinary significance.

Abstract:
Monitoring of the helminth fauna of small rodents living on drainage channel banks on arable lands was carried out in 2017 in Brest Polesie (western part of Belarusian Polesie). 1,000 trap-days were worked out and 190 animals of 6 species were caught. The common vole was dominant, the striped field mouse was the subdominant. The total infection of rodents with helminths was 76.8%. 24 species of helminths were found. The nematode Syphacia nigeriana Baylis, 1928 more often invaded common and root voles, the nematode Heligmosomoides polygyrus (Dujardin, 1845) - stripped field and yellow-necked mice, the nematode Heligmosomum mixtum Schulz, 1954 - red-backed voles. The trematode Psilotrema spiculigerum (Muhling, 1898) (host: common vole) and the acanthocephalan Moniliformis moniliformis (Bremser, 1811) (host: striped field mouse) were not previously recorded in small rodents on channel banks. Four species of helminths have medical and veterinary significance.

Abstract:
Introdução: Os Helmintos são parasitos comumente chamados de vermes, que normalmente tem um ciclo de vida livre ou um ciclo de vida parasitária, ocasionando nesta última, doenças no homem ao entrar em contato com o organismo dele. Estes se classificam em: Nematelmintos e Platelmintos, de acordo com as características do corpo destes vermes, sendo cilíndrico e achatado dorso-ventral, respectivamente. Estes parasitos são hematófagos, ou seja, se alimentam de sangue, e também de restos alimentares do ser humano, ocasionando anemia e desnutrição. Ao entrar no hospedeiro humano, o individuo ativa o seu sistema imune aumentando as células Th2 para combater a invasão e como consequência, produz aumento dos Eosinófilos, chamada de Eosinofilia. Objetivo: Apresentar evidências na literatura acerca dos câmbios hematológicos que são gerados no hemograma completo, nos pacientes infectados por helmintos, tendo como parâmetros a Hemoglobina e os Eosinófilos. Materiais e Métodos: Trata-se de uma revisão de literatura através de artigos coletados na base de dados de "Scielo" e "Google Acadêmico". Foram utilizadas as Palavras-Chave: "Helmintos", "Hematófagos", "Anemia", "Eosinofilia" e “Ciclo de Loss”. Selecionou-se 10 artigos conforme critérios da abordagem da temática. Resultados: As Helmintoses ocasionadas pelos helmintos Ascaris lumbricoides, Estrongyloides stercoralis e Ancylostoma duodenali produzem alterações no hemograma completo nos pacientes infectados por estes vermes, especificamente diminuição da Hemoglobina, o que implica em Anemia, já quê, são parasitos hematófagos, e por estes parasitos fazerem o ciclo de Loss ao nível pulmonar para completar a sua maturação, ocasionam uma resposta imune exacerbada do individuo refletindo no hemograma completo com Eosinofilia (aumento dos eosinófilos). As alterações no hemograma completo tanto nos níveis de hemoglobina como nos níveis dos eosinófilos nas Helmintoses, fazem deste exame, um alvo de subjetividade de infecções parasitárias, que logo se confirmarão por médio do exame coproparasitológico das fezes. Conclusão: As alterações hematológicas presentes no hemograma completo produto da infestação por Helmintos, fazem direcionar o possível diagnóstico de doença parasitária.

Abstract:
Introdução: Em 2010, registrou-se cerca de 1 bilhão de casos de doenças causadas por helmintos no mundo. Diante disso, a Organização Mundial da Saúde (OMS) sugeriu a quimioprofilaxia periódica como tratamento preventivo de verminoses. A principal classe medicamentosa utilizada são os anti-helmínticos benzimidazólicos, que se mostraram eficazes no tratamento de verminoses, mas com potencial limitado em algunscasos. Logo, surgiu a hipótese de que uma exposição prolongada a tais drogas seria capaz de selecionar helmintos mais resistentes. Objetivos: 1) Compreender o mecanismo de ação dos benzimidazólicos; 2) Investigar a presença de resistência à medicação. Material e métodos: O presente estudo é uma revisão de literatura realizadamediante a busca pelos descritores “drugs resistance”, “helminths” e “benzimidazole”, na base de dados PubMed. Foram encontrados 439 artigos, dos quais 9, realizados entre os anos de 2010 a 2022, foram selecionados. Resultados: Estudos demonstram que benzimidazólicos agem na ligação à proteína β-tubulina, subunidade de microtúbulos, estruturas responsáveis pela homeostase celular. Dessa forma, estes sofrem encurtamento, resultando na morte celular do parasita. Todavia, após a descoberta de resistência à medicação em animais, questionou-se a presença de helmintos resistentes adrogas em humanos. Pesquisas feitas através de qPCR comprovaram a influência de fatores genéticos e ambientais na resistência parasitária. Com isso, foi identificado um polimorfismo de nucleotídeo único, nos códons 167, 198 e 200 do gene da β-tubulina, responsáveis por alterações celulares, impedindo a associação de benzimidazólicos ao sítio de ligação desta proteína. Ademais, o número de helmintos de vida livre, sensíveis à medicação, diminui a cada administração errônea de drogas, dosagens em curto período de tempo, e ao clima quente e seco, selecionando parasitas resistentes. Estudos brasileiros e australianos mostraram que A. lumbricoides, N. americanus e T. trichiura são os helmintos com maior prevalência de cepas resistentes. Entretanto, os benzimidazólicos conseguiram eliminar a maioria desses vermes. Conclusão: Comprovou se a existência de helmintos resistentes aos benzimidazólicos. Contudo, a prevalência dos mesmos ainda é baixa, sendo uma preocupação de saúde pública para os próximos anos, visto que o número de cepas resistentes aumenta com a administração errada de drogas e com mutações genéticas dos próprios parasitas.
