Alterações hematológicas comparativas entre equinos e asininos associadas à carga parasitária (OPG) naturalmente infectados por parasitos gastrintestinais na ilha de São Luís, Maranhão

Abstract

In order to verify the possible hematological alterations related to intestinal parasitism in naturally infected horses and donkeys on the island of Sao Luis, Ma was selected 57 horses and 37 donkeys adults, breed, age and weight varied, divided into four groups according to the EPG parasite load > 500 and ≤ 500, we assessed parasite interspecific association and LPG so that it was observed that the counting of eggs per gram of faeces (EPG) showed a range 0 - 3000 EPG for horses and donkeys to 0 - 6900 , the search for larvae in both species showed higher frequency for the association Cyathostominae - Strongylus vulgaris, which has resulted mainly in the group of donkeys with OPG ≤ 500, high average values in total leukocytes, band neutrophils, eosinophils and lymphocytes. Such findings indicate the existence of mild leukocytosis with eosinophilia with or without elevation of other cells, demonstrating that the eosinophilia is a flag for the presence of intestinal parasites for donkeys, even when they have low values for the counting of EPG.
