An acute poisoning with sodium fluorsilicate in six cattle is reported, as well as the experimental reproduction by oral administration of the compound to two bovines. Clinical manifestations of the natural poisoning include muscle tremors, hypersalivation, groaning and rapid death. In the experimental poisoning lateral recumbency, dyspnea, tetanic spasms and paddling was also observed. The main necropsy findings were reddening, edema and ulceration of the ruminal and abomasal mucosa. Histopathological findings were necrosis of the epithelium of the forestomachs with polymorphonuclear infiltration of the submucosal and muscular layers. Tubular renal necrosis, liver portal necrosis and necrosis of the lymphoid tissues was also noted. The sodium fluorsilicate caused clinical signs at a dose of 300mg/kg, and death from 400mg/kg on. |
