“…Devido à migração das larvas ocorre arterite ileocecocólica evidenciada histologicamente por inflamação multifocal, necrose e fibrose, havendo evidências de que o fator de necrose tumoral (TNF) e a interleucina (IL-1) sejam os mediadores-chave envolvidos em deflagrar a cascata inflamatória (Drudge et al 1966, Duncan & Pirie 1975, Drudge 1979, Slocomb 1985, Klei et al 1990, Morris 1991, Moore et al 1995.…”

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. Palavras-chave: equideos; Strongylus vulgaris; valores leucocitários GASTROINTESTINAL PARASITISM AND HEMATOLOGY IN HORSES AND DONKEYS FROM THE URBAN AREA OF SÃO LUÍS/MA, NORTHEAST BRAZILABSTRACT: This research paper aimed to evaluate the hematological changes related to natural gastrointestinal parasite load in infected horses and donkeys on the island of Sao Luis, MA. 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.

“…Larger studies of colic and peritonitis in horses have, however, described pyrexia, peritonitis and palpation per rectum of a painful and thickened mesenteric root in horses with S. vulgaris-associated colic [11][12][13]. Fibrin deposits on the sites of infarction and peritonitis were also described [1,4,8,9,[15][16][17]. On post-mortem examination, nonstrangulating intestinal infarction of the small and large intestine was described as clearly demarcated areas that were black to red in colour and raised above the level of the healthy intestine.…”

In areas where S. vulgaris is prevalent, nonstrangulating intestinal infarction should be considered as a differential diagnosis in horses presenting with mild colic and peritonitis. Survival of nonstrangulating intestinal infarction is possible in cases where surgical intervention with resection of the infarcted intestine is feasible. The summary is available in Spanish - see Supporting Information.

<p>El presente trabajo tuvo como objetivo evaluar los parásitos gastrointestinales de equinos procedentes de ocho localidades de la Provincia de Corrientes, Argentina. Mediante técnicas de concentración se examinaron 30 muestras fecales a fin de identificar los helmintos y protozoos, así como estimar la prevalencia general y específica. Se registró una prevalencia general de P=50% y se identificaron cuatro taxones (S=4) representados por dos protozoos, Blastocystis sp (P=3,3%) y Eimeria sp (P=16,6%) y dos nematodes, Strongylus sp (P=13%) y Cyathostomun sp (P=20%). La mayoría de los reportes sobre parásitos en equinos se refieren a nematodes, por lo que el registro de protozoos es un aporte novedoso al conocimiento sobre el tema. Respecto a los nematodes identificados, han sido reportados en diferentes provincias argentinas y los grandes estróngilos representan los de menor prevalencia, mientras que los pequeños estróngilos, género Cyathostomun, los de mayor prevalencia. Los resultados obtenidos acrecientan el conocimiento sobre la temática y ponen en relieve la necesidad de implementar medidas sanitarias a fin de controlar la transmisión y mantener las cargas parasitarias por debajo de niveles que potencialmente afecten la salud, productividad o performance de los equinos.</p>
