RESUMO:Objetivou-se avaliar as alterações hematológicas relacionadas à carga parasitária gastrintestinal em equinos e asininos naturalmente infectados na Ilha de São Luis, MA. Foram selecionados aleatoriamente 57 equinos e 37 asininos adultos, sem raça definida, de idade e pesos variados. Exames coproparasitológicos foram realizados pelos métodos de Willis-Mollay, GordonWhitlock, Robert O'Sulivan. Os animais foram distribuídos em quatro grupos, conforme carga parasitária e espécie animal em: grupo 1 -asininos com OPG ≤500; grupo 2 -asininos com OPG >500; grupo 3 -equinos com OPG ≤500; e grupo 4 -equinos com OPG >500. Os resultados obtidos na contagem de ovos por gramas de fezes (OPG) apresentaram uma variação de 0 a 3.000 OPG para equinos e 0 a 6.900 para asininos, a pesquisa de larvas em ambas as espécies indicou maior frequência para a associação Cyathostominae -Strongylus vulgaris, o que determinou principalmente no grupo dos asininos com OPG ≤500, valores médios elevados na contagem total de leucócitos, bastonetes, eosinófilos e linfócitos. Tais achados apontam a existência de leve leucocitose com eosinofilia associada ou não a elevação de outras células, demonstrando que a eosinofilia foi um sinalizador de presença de parasitismo intestinal para asininos, mesmo quando estes apresentam valores baixos para a contagem do OPG.

The animals selected were 57 horses and 37 donkeys, mixed breed, varied ages and weight, were randomly selected. Fecal examinations were performed by Willis-Mollay, Gordon-Whitlock, and Robert O'Sulivan methods. The animals were divided into four groups according to parasitic load and animal species in: group 1 -donkeys with EPG ≤ 500; group 2 -donkeys with EPG > 500; group 3 -horses with EPG ≤ 500, and group 4 -horses with EPG > 500. The results obtained in eggs per gram of feces counting (EPG) showed a variation from 0 to 3,000 EPG for horses and 0 to 6,900 for donkeys; the larval culture results in both species showed a higher frequency of CyathostominaeStrongylus vulgaris association which resulted, mainly in the group of donkeys with ≤ 500 EPG, high average values in leukocyte, rod cells, eosinophils, and lymphocytes total counting. Such findings indicate the existence of mild leukocytosis with eosinophilia associated or not with the elevation of other cells, showing that eosinophilia was a marker for the presence of intestinal parasitism for donkeys, even when they have low values of EPG counting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
