| In the field of studies of acute toxicity induced by bacterial agents, Shiga toxins have been relevant due to the severity of the extra-intestinal diseases they cause. Numerous studies have shown that Shiga toxin induced apoptosis in different cell types; however, this important process has been little studied in vivo experimental models. In this study, the effects of excretion products of Shigella dysenteriae, in which Shiga toxin is present, we investigated on early larval stages of Zebrafish, an animal model with many advantages over other in vivo experimental models traditionally used. Both the collection of eggs and larvae of Zebrafish, and the product from excretion from Shigella dysenteriae (SdyEP) were performed according to laboratory standards.... |
