Abstract: An inflammation is generated during formation of Amoebic Liver Abscess. We analyzed chemically sympathectomized hamsters with Amoebic Liver Abscess, in a period between 6 hours to 7 days. The liver tissue samples were analyzed by haematoxylin and eosin staining, immunohistochemistry, immunofluorescence and morphometry. Sympathectomy caused a lower production of collagen and absence of granuloma tissue of Amoebic Liver Abscess. At the 6 h of development, proinflammatory cytokines were reduced, also reduced 12 hours – 7 days; while IL-10 production was incresed for this time; Transforming Growth Factor-β producing cells only increased from 4 to 7 days. Nuclear factor kappa-light-chain-enhancer of activated B cells were diminished throughout the Amoebic Liver Abscess, while Toll Like Receptor 4 + macrophages decreased in the period of 2 to 7 days; and Toll Like Receptor 4 + neutrophils decreased between 4 and 7 days. The population of trophozoites was increased in sympathectomized animals between 4 and 7 days. The chemical sympathectomy reduces the collagen deposition and induces an anti-inflammatory state during the development of Amoebic Liver Abscess, then; allows the spread and reproduction of Entamoeba histolytica trophozoites.
