Equine parasites are considered responsible for the decrease in sports performance and \ncause alterations in development during their juvenile stage. The environment where they are \nand the management applied to them, affects the greater or lesser incidence in the appearance of parasitic diseases. Currently the indiscriminate use of antiparasitics has led to the appearance of resistance in Nematodes, cestodes and protozoa in this animal species. Parasitic resistance can occur intrinsically or acquired. Intrinsic or natural resistance is due to characteristics of the \nparasite that make it insensitive to the effect of the drug. On the other hand, acquired resistance occurs because survivors of drug treatments transfer their resistance genes to their progeny (Sangster & Gill, 2001). Once resistance develops in a parasite population, there is no way to reverse it (Sangster & Gill, 2001). Nematodes in particular, having a high level of genetic diversity \nin their populations, are predisposed to develop resistance and therefore to persist (Kaplan R. M., 2004).\nThe intestinal parasites with the greatest impact on the sports performance of equines correspond to the following families: Anoplocephalinae (Anaplocephala spp), Ascaridae \n(Parascaris equorum), large strongylus; Strongylinae (strongylusspp),small Strongylus (subfamily \nCyathostominae), Oxyuridae (Oxyuris equi), Strongyloididae (Strongyloides westeri) and \nDictyocaulidae (Dictyocaulus arnfieldi). Being able to identify the type of parasites and degree of infection allows evaluating the need to apply or not a treatment, since some parasites such as Strongylus vulgaris are highly pathogenic. The objective of this work was to evaluate the internal \nparasite load and identify the presence of Ectoparasites, in an establishment in which horses are used for sporting purposes and remain in a stable state. An external clinical review and fecal \nmatter samples were taken from 100 horses of Creole, pure Argentine and quarter-mile breeds with ages between 6 and 19 years, two samplings were made, one in the months of February / \nMarch, a second sampling in September / October 2018. For the determination of Ectoparasites, an external clinical review was carried out to detect the presence of lice and lesions produced by \nscabies mites. To evaluate the presence of Oxiuris equi eggs, a perianal sample was taken using the adhesive tape method. The stool samples were collected and kept refrigerated until their \nevaluation in the Parasitology Department of the College of Veterinary Sciences of the UBA. They \nwere evaluated using the eggs per gram of fecal matter (hpg) technique with supersaturated sodium chloride solution, flotation technique, modified McMaster technique and Baerman technique. No eggs of Oxyuris equi, Dictyocaulus arnfieldi and external parasites were found. The results of the hpg for large and small Strongylusshowed in a first sampling carried out in February / March 2018 that 85% of the horses presented parasite loads of 1-500 hpg (+) considered a low \nintensity of infection, 15% of the equines presented 501 to 5000 hpg (++) considered a moderate intensity and 0% of the equines presented more than 5000 hpg (+++) considered a severe intensity or parasite load. In a second sampling carried out in September / October 2018, 66% of the equines presented parasite loads of 1-500 hpg (+), 31% of the equines presented 501 to 5000 hpg (++) and 3% of the equines I present a parasite load> 5001 hpg (+++). Stool cultures were carried out for the identification of larvae, finding small strongylus and were identified by morphology: subfamily Cyathostominae, Cyathostomum A. Negative results in ectoparasites and \nOxyuris equi as well as low hpg values in horses maintained with good management practices \n(removal of fecal matter, daily brushing, adequate feeding) reinforce the importance of the prevention of parasitic diseases that affect sporting equines and the rational use of antiparasitics to avoid resistance. |

Buenos Aires, Argentina Ribicich, Mabel Moreno, Fabián Arturo 2022-05-05 Los parásitos de los equinos son considerados responsables en la disminución del rendimiento deportivo y provocan\nalteraciones en el desarrollo durante su etapa juvenil. El \nmedio ambiente donde se encuentran y el manejo aplicado sobre los mismos, repercute sobre la mayor o menor incidencia en la aparición de enfermedades parasitarias. Actualmente el uso indiscriminado de los antiparasitarios ha llevado a que aparezca resistencia en nematodos,cestodos y protozoarios en esta especie animal. La resistencia\nparasitaria puede suceder de forma intrínseca o adquirida. La resistencia intrínseca o natural se debe a características propias \ndel parásito que lo hacen insensible al efecto del fármaco. Por otro lado, la resistencia adquirida \ntiene lugar debido a que los sobrevivientes a los\ntratamientos farmacológicos transfieren sus genes de resistencia a su progenie (Sangster & Gill, 2001). Una vez que se genera resistencia en una población de parásitos, no hay manera de revertirla (Sangster & Gill, 2001). Los nematodos\nen particular, al tener un alto nivel de diversidad genética en sus poblaciones, están \npredispuestos a desarrollar resistencia y por ende a persistir (Kaplan R. M., 2004).\nLos parásitos intestinales con mayor impacto en el rendimiento deportivo de los equinos corresponden a las siguientes familias: Anoplocephalinae (Anaplocephala spp), Ascarididae\n(Parascaris equorum), grandes Strongylus; Strongylidae Strongylus spp, pequeños strongylus\n(subfamilia Cyathostominae), Oxyuridae (Oxyuris equi), Strongyloididae (Strongyloides westeri) y \nDictyocaulidae (Dictyocaulus arnfieldi). El poder identificar el tipo de parásitos y grado de infección permite evaluar la necesidad de aplicar o no un tratamiento, ya que algunos parásitos \ncomo Strongylus vulgaris son altamente patógenos. El objetivo de este trabajo fue evaluar la carga de parásitos internos e identificar la presencia de ectoparásitos, en un establecimiento en \nel cual los caballos se utilizan para fines deportivos, también con fines militares, como guardia \npresidencial y permanecen bajo estado de estabulación. Se realizó revisión clínica externa y toma de muestras de materia fecal a 100 equinos escogidos aleatoriamente, de razas Criollo, Puro Argentino y Cuarto de Milla, con edades entre 6 a 19 años, se hicieron dos muestreos, uno en los meses de febrero /marzo, un segundo muestreo escogiendo aleatoriamente igual al primer muestreo con 100 equinos en septiembre/ octubre de 2018. Para la determinación de \nectoparásitos se realizó la revisión clínica externa para detectar la presencia de piojos y lesiones producidas por ácaros de la sarna. Para evaluar la presencia de\nhuevos de Oxiuris equi se realizó la toma de muestra perianal con el método de la cinta adhesiva. Las muestras de materia fecal \nfueron recolectadas en el Regimiento de Granaderos a Caballo General San Martín del Ejército Argentino (RGACGSM), y mantenidas en refrigeración hasta su evaluación en la Cátedra de \nParasitología de la Facultad de Ciencias Veterinarias (FCV) de la Universidad de Buenos Aires (UBA). Las mismas se evaluaron mediante la técnica de huevos por gramo de materia fecal (hpg) con solución sobresaturada de cloruro de sodio, técnica de flotación, técnica de Mc Master modificada y la técnica de Baerman. No se encontraron huevos de Oxyuris equi, Dictyocaulus \narnfieldi y parásitos externos. Los resultados de los hpg para grandes y pequeños strongilídeos\nmostraron en un primer muestreo realizado en febrero / marzo 2018 que el 85% de los equinos \npresentaron cargas parasitarias de 1-500 hpg (+) consideradas una intensidad baja de infección, el 15% de los equinos presentó 501 a 5000 hpg (++) considerada una intensidad moderada y el \n0% de los equinos presentó más de 5000 hpg (+++) considerada una intensidad o carga parasitaria severa. En un segundo muestreo realizado en septiembre / octubre 2018, el 66% de los equinos presentaron cargas parasitarias bajas 1-500 hpg (+), el 31 % de los equinos presento cargas parasitarias moderadas 501 a 5000 hpg (++) y el 3 % de los equinos presento carga parasitaria\nseveras >5001 hpg (+++). Se realizaron coprocultivos para la identificación de larvas, encontrando \npequeños Strongylus (subfamilia Cyathostominae). Se encontraron resultados negativos para ectoparásitos y Oxyuris equi y bajos valores de hpg en equinos mantenidos con buenas prácticas de manejo y buenas prácticas de bienestar animal en caballos (remoción de materia fecal, \ncepillado diario, alimentación adecuada, servicio médico veterinario, manejo sanitario). Estos \nresultados refuerzan la importancia de la prevención de las enfermedades parasitarias que afectan a los equinos deportivos y el uso racional de antiparasitarios para evitar la resistencia. application/pdf Parasitos Equinos Lesiones Hospedador Larvas Hpg Coprocultivos RGACGS Parasites Equines Lesions Host Larvae Hpg Stool cultures spa Universidad de Buenos Aires.
