Prevalencia de parásitos gastrointestinales en equinos y factores de riesgo asociados en varias zonas de Antioquia, Colombia
Medellín Colombia, 2018Co-Authors: Chaparro Gutiérrez, Jenny Jovana, Ramírez Vásquez, Nicolás Fernando, Piedrahita Diego, Strauch Alejandro, Sánchez Alfredo, Tobón Julio, Olivera Ángel Martha, Ortiz Orteaga Diego, Villar Argaiz DavidAbstract:ABSTRACT: There are few reports on the prevalence of gastrointestinal parasites in equines in Colombia. In this study, 946 horses were sampled from a total of 204 farms in the municipalities of Rionegro and those that comprise the Valle de Aburrá, in the department of Antioquia. Fecal samples were taken directly from the rectum and processed by the McMaster, Baermann and Graham techniques. The prevalence of parasites at the farm level was 56.3% for Strongylidae, 10.7% for Strongyloides spp, 2.8% for Oxyuridae and 0.3% for Dictyocaulus spp. From a practical point of view, the most pathogenic parasites and of greatest resistance concern were the Cyathostomids, which are included within the Strongylidae and whose prevalence was greater than 50%. The OR of presenting Strongylidae was 49% lower in equines that participated in fairs compared to those that did not. The OR of presenting Strongylidae was 56% lower in equines that use stables than those not being stalled. Also, the OR of being positive to Oxyuris equi was 88% lower in animals that participate in fairs compared to those that did not, and was 3.66 times higher in equines with body condition ≤ 2 in comparison with those of body condition ≥3. Based on this information, it is important to initiate studies that evaluate the state of antihelminthic resistance and the relationship between parasitic load and clinical condition in order to determine the real impact of these parasites on the equines of these regions.RESUMEN: Existen pocos reportes de la prevalencia de parásitos gastrointestinales en equinos en Colombia.

Archéologie d’un parasite du cheval
'OpenEdition', 2017Co-Authors: Dufour Benjamin, Matthieu Le BaillyAbstract:Oxyuris equi, l’oxyure du cheval, est un vers parasite spécifique des équidés régulièrement mis en évidence lors des études paléoparasitologiques. Nous proposons ici une synthèse originale entre les mentions de ce parasite connues dans la bibliographie et les textes anciens, avec des données inédites issues de nos recherches en paléoparasitologie. Cette compilation des données montre que la plus ancienne observation de l’oxyure du cheval date du milieu du Ier millénaire avant notre ère en Asie centrale, et du second âge du Fer en Europe de l’Ouest. Les mouvements de populations au moment de la conquête romaine, les échanges commerciaux et l’avancée des troupes à travers l’Empire romain ont pu contribuer à diffuser le parasite en Europe de l’Ouest. Il apparaît également que l’oxyure du cheval n’est pas détecté sur le continent américain avant l’époque contemporaine. Le rôle des migrations européennes autour du xve siècle est discuté pour expliquer l’observation tardive d’Oxyuris equi sur le continent américain. L’absence d’observation de ce parasite avant l’âge du Fer en Eurasie peut également s’expliquer par son écologie, un échantillonnage non favorable, voire la relative rareté des restes de chevaux sur les sites archéologiques.The intestinal pinworm Oxyuris equi is a parasite that specifically affects horses and that is regularly picked up in parasitological analyses. Here we give an overview combining references to these parasites in the literature and in ancient sources with hitherto unpublished results from our own palaeo-parasitological studies. This reveals that the earliest case of horse pinworm dates to the middle of the first millennium BC in central Asia, and to the Later Iron Age in western Europe. Population movements at the time of the Roman conquest, trade and exchange, and the movement of troops within the Roman empire may have contributed to the spread of this parasite in western Europe. It seems that the horse pinworm does not appear in America before the modern period. The role European emigration around the fifteenth century may have played in the late introduction of Oxyuris equi on the American continent is also discussed. The absence of evidence for pinworms before the Iron Age in Eurasia may perhaps be explained by its ecology, by unfavourable sampling conditions, or even by the rarity of finds of horses on archaeological sites.Oxyuris equi, la oxiuriasis equina, es una enfermedad parasitaria propia de los équidos transmitida por un gusano de la cual se encuentran regularmente evidencias a través de estudios paleoparasitológicos. En el presente texto se propone una síntesis original de las menciones de dicho parásito encontradas en la bibliografía y los textos antiguos, además de datos inéditos recabados durante nuestras investigaciones en paleoparasitología. El acerbo de datos muestra que las observaciones más antiguas de la oxiuriasis equina remontan a mediados del primer milenio antes de nuestra era en Asia central y a la Segunda Edad del Hierro en Europa occidental. Los desplazamientos de población durante la conquista romana, así como los intercambios comerciales y el avance de las tropas a través del Imperio romano, pudieron contribuir a la difusión de este parásito en Europa occidental. Se observa además que no existen rastros de oxiuriasis equina en el continente americano antes del período contemporáneo. Con el fin de explicar la observación tardía de Oxyuris equi en dicho continente, se discute el papel desempeñado por las migraciones europeas alrededor del siglo XV. Por lo demás, el hecho de que no se hayan encontrado rastros del parásito antes de la Edad del Hierro en Eurasia puede deberse a su ecología, a muestrarios poco favorables, e incluso a la presencia relativamente escasa de restos de caballos en los sitios arqueológicos

the horse pinworm Oxyuris equi in archaeology during the holocene review of past records and new data
Infection Genetics and Evolution, 2015Co-Authors: Benjamin Dufour, Jeanpierre Hugot, Sebastien Lepetz, Matthieu Le BaillyAbstract:This paper focuses on the horse pinworm, Oxyuris equi, in archaeology during the Holocene period, and presents an overview of past published occurrences, early mentions in texts, and new data from our paleoparasitology research. This original compilation shows that the most ancient record of the horse pinworm dates to ca. 2500 years before present (ybp) in Central Asia and to ca. 2020 ybp in Western Europe. It also shows that the parasite is not detected on the American continent until contemporary periods. The role of European migrations from 1492 (Christopher Columbus) is discussed to explain the transfer of the horse pinworm from the Old World to the Americas. The absence of any record of this parasite before ca. 2500 ybp in Eurasia could be explained by parasite ecology, unfavorable sampling and scarcity of horse archeological remains. For the Americas, the absence of horse for long periods can be an additional explanation for the absence of the parasite.

Paleoparasitological remains revealed by seven historic contexts from Place dArmes, Namur, Belgium
2015Co-Authors: Gino Chaves Da Rocha, Matthieu Le Bailly, Adauto Araujo, Stephanie Harter- Lailheugue, Luiz Fern, O Ferreira, Nicolau M. Da Serra-freireAbstract:Human occupation for several centuries was recorded in the archaeological layers of Place dArmes, Namur, Belgium. Preventive archaeological excavations were carried out between 1996/1997 and seven historical strata were observed, from Gallo-Roman period up to Modern Times. Soil samples from cesspools, latrines, and structures-like were studied and revealed intestinal parasite eggs in the different archaeological contexts. Ascaris lumbricoides, A. suum, Trichuris trichiura, T. suis. Taenia sp., Fasciola hepatica, Diphyllobothrium sp., Capillaria sp. and Oxyuris equi eggs were found. Paleoparasitology confirmed the use of structures as latrines or cesspit as firstly supposed by the archaeologists. Medieval latrines were not only used for rejection of human excrements. The finding of Ascaris sp. and Trichuris sp. eggs may point to humans or wild swines feces. Gallo-Roman people used to eat wild boar. Therefore, both A. suum and T. suis, or A. lumbricoides and T. trichuris, may be present, considering a swine carcass recovered into a cesspit. Careful sediment analysis may reveal its origin, although parasites of domestic animals can be found together with those of humans. Taenia sp. eggs identified in latrine samples indicate ingestion of uncooked beef with cysticercoid larvae. F. hepatica eggs suggest the ingestion of raw contaminated vegetables and Diphyllobothrium sp. eggs indicate contaminated fresh-water fish consumption. Ascaris sp. and Trichuris sp. eggs indicate fecal-oral infection by human and/or animal excrements

Field study on the efficacy of an oral 2% ivermectin formulation in horses Eficácia a campo de uma formulação oral de ivermectina a 2% em equinos
Colégio Brasileiro de Parasitologia Veterinaria, 2011Co-Authors: André Antonio Cutolo, Anderson Tintino Dos Santos, Silmara Marques AllegrettiAbstract:Twenty horses naturally infected with nematodes were included in a blind, controlled field study on efficacy and safety of an oral 2% ivermectin formulation at a dose of 0.2 mg.kg-1. Horses were divided into treated and non-treated (control) groups with ten animals each based on preliminary counts of eggs per gram of feces (EPG). Stool samples were collected after treatment for identification of nematode species. Clinical evaluations and EPG counts were performed on days 0, +5, +14 and +19. Nineteen nematode species were identified: Coronocyclus ulambajari, Craterostomum acuticaudatum, Cyathostomum catinatum, Cyathostomum pateratum, Cylicocyclus brevicapsulatus, Cylicocyclus insigne, Cylicocyclus leptostomum, Cylicocyclus nassatus, Cylicocyclus ultrajectinus, Cylicocyclus spp., Cylicostephanus calicatus, Cylicostephanus longibursatus, Cylicostephanus poculatus, Habronema muscae, Habronema spp., Parascaris equorum, Poteriostomum imparidentatum, Oxyuris equi and Triodontophorus spp. The mean EPG counts of treated and non-treated (control) groups on Days -15, 0, +5, +14 and +19 were 1925, 1340, 0, 12.5, 0, 1470, 790, 875, 1605 and 1240 respectively. The efficacy of treatment on Days +5, +14 and +19 was 100, 99.2 and 100% respectively, with a significant difference compared to the control group (p < 0.01). The product was considered to be safe with no findings of clinical significant changes during the study.Vinte equinos naturalmente infectados com nematódeos foram utilizados em estudo cego, controlado, de eficácia e segurança clínica a campo de uma formulação oral de ivermectina a 2%, na dosagem de 0,2 mg.kg-1.

Caracterização de endo e ectoparasitas em equídeos sacrificados para consumo humano
'Universidad Cooperativa de Colombia- UCC', 2019Co-Authors: Uribe Nelson, Betancourt Antonio, Hernández DarwinAbstract:Introduction: To identify endo and ectoparasites in equids slaughtered at the Villa Rosa slaughter house in Piedecuesta, Santander, between October and December 2015. Metodology: For ecto and hemoparasites studies, 83 equids were employed, and 75 for gastrointestinal parasites. Ectoparasites were collected directly from the skin and hemoparasites by blood culture, Woo, wet preparations, stained smears and Knott Technique. Gastrointestinal parasites were studied by Mc Master and Sedimentation-Flotation techniques, as well as feces cultivation and helminthological necropsy. Results: Anocentor nitens ticks were found on 31,32 % of the equids and 8,43 % had mixed infestation with Amblyomma cajennense s.l.. The louse Haematopinus asini was collected from one animal. Except for the presence of Setaria equina microfilariae, in 7,2 % of the samples, no hemoparasites were detected with the parasitological methods employed. “Strongylid type” eggs were found in 88% of the samples, Dictyocaulus sp. in 6,6 %; Parascaris sp. in 5,3 %; Oxyuris sp. in 5,3 %; Strongyloides sp. in 1,33 % and Anoplocephala sp. in 9.3%. Culturing of feces yielded only 12 L3 larvae of the Cyathostominae or “Small Strongyles” group and one of Trichostrongylus axei. Helminthological necropsies recovered adults of Habronema megastoma, Setaria equina, Oxyuris equi, Strongylus spp., Triodontophorus, Cyathostominae and Anoplocephala perfoliata. Conclusions: Parasitisms by ticks, large and small strongyles and tapeworms are common in horses slaughtered in Piedecuesta, Santander. Serologic and molecular tests are recommended to detect hemoparasites in future studies.Introducción: el parasitismo es uno de los principales problemas de salud y producción animal en Colombia, como lo es en otros países de la región; por lo tanto, es importante identificar aquellos más frecuentes con el propósito de considerar estrategias de prevención y control. Este trabajo se realizó con el objetivo de aportar al conocimiento sobre los endoparásitos y ectoparásitos presentes en los équidos sacrificados entre octubre y diciembre de 2015 en la Planta de Beneficio Villa Rosa, Piedecuesta, Santander, Colombia. Metodología: para la identificación de los ectoparásitos y hemoparásitos se utilizaron 83 équidos, y 75, para los parásitos gastrointestinales. Los ectoparásitos se colectaron directamente de la piel y para los hemoparásitos se utilizaron las técnicas de hemocultivo, Woo, preparaciones en fresco, extendidos coloreados y Knott. Los parásitos gastrointestinales se estudiaron mediante las técnicas de McMaster, sedimentación-flotación, cultivo de heces y necropsia helmintológica. Resultados: el 31,32 % de los équidos examinados estaban parasitados con Anocentor nitens y el 8,43 % presentó infestación mixta con Amblyomma cajennense s.l. El piojo Haematopinus asini fue colectado en un animal. Salvo la presencia de microfilarias de Setaria equina en 7,2 % de las muestras, no se detectaron hemoparásitos con los procedimientos parasitológicos empleados. Se observaron huevos tipo Strongylida en 88 % de las muestras; Dictyocaulus sp. en 6,6 %; Parascaris sp. en 5,33 %; Oxyuris sp. en 5,33 %; Strongyloides sp. en 1,33 % y Anoplocephala sp. en 9,3 %. En el cultivo de heces se observaron 12 larvas L3 de la subfamilia Cyathostominae o “pequeños Strongylus” y una del nematodo Trichostrongylus axei. En las necropsias se hallaron adultos de: Habronema megastoma, Setaria equina, Oxyuris equi, Strongylus sp., Triodontophorus, Cyathostominae y Anoplocephala perfoliata. Conclusiones: los parasitismos por garrapatas, grandes y pequeños estróngilos y tenias, son frecuentes en los equinos sacrificados. Se recomiendan técnicas serológicas y moleculares para detectar hemoparásitos en estudios posteriores.Introdução: o parasitismo é um dos principais problemas de saúde e produção animal na Colômbia, assim como acontece em outros países da região; portanto, é importante identificar aqueles mais frequentes com o propósito de considerar estratégias de prevenção e controle.

Resultados: 31,32 % dos equídeos examinados estavam parasitados com Anocentor nitens e 8,43 % apresentaram infestação mista com Amblyomma cajennense s.l. O piolho Haematopinus asini foi coletado em um animal. Salvo a presença de microfilárias de Setaria equina em 7,2 % das amostras, não foram detectados hemoparasitas com os procedimentos parasitológicos empregados. Foram observados ovos tipo Strongylida em 88 % das amostras; Dictyocaulus sp. em 6,6 %; Parascaris sp. em 5,33 %; Oxyuris sp. em 5,33 %; Strongyloides sp. em 1,33 % e Anoplocephala sp. em 9,3 %. Na cultura de fezes, foram observadas 12 larvas L3 da subfamília Cyathostominae ou “pequenos Strongylus” e uma do nematódeo Trichostrongylus axei. Nas necropsias, foram encontrados adultos de: Habronema megastoma, Setaria equina, Oxyuris equi, Strongylus sp., Triodontophorus, Cyathostominae e Anoplocephala perfoliata. Conclusões: os parasitismos por carrapatos, grandes e pequenos estrôngilos e tênias são frequentes nos equinos sacrificados. Recomendam-se técnicas serológicas e moleculares para detectar hemoparasitas em estudos posteriores
