中文摘要 | 取l05的豬附紅血球體(Eperythrozoon suis)感染6週齡的去脾三品種肉豬,感 染後7-10天內死亡的豬隻分別進行病理,組織學之觀察。肉眼病變檢查可見全身性黃疸,包 括全身性皮下脂肪、胸腔、腹腔內脂肪,心臟冠狀溝脂肪均呈黃色,肝臟呈微黃色或紅褐色 斑,部分有腹水或胸水出現,全身淋巴節呈現周邊性出血或腫脹,病程長則可見腎臟表面及 實質有黃白色散發的小點。組織病理學檢查於肝臟可見肝索細胞離散現象,竇間隙變大,小 葉中央靜脈區脂肪變性或壞死,小葉內及小葉間有淋巴樣細胞浸潤,及庫佛氏細胞增生並吞 噬紅血球。淋巴小節的生發中心內之淋巴細胞減少或壞死,並可見到細胞碎片及巨細胞吞噬 紅血球。腎臟的皮質及髓質有類淋巴小節產生且已發展成生發中心。鐵色素染色法並未見到 血鐵素存在。 |
英文摘要 | Eight week old splenectomized pigs inoculated with 105 Eperythrozoon suis organisms died within the 7th day to the 10th day post inoculation were necropsied. The major gross lesions in these pigs were yellowish discoloration (icterus) of the skin and the fatty tissues of all the visceral organs These included the submucosa of the visceral pleural, abdominal, subepicardial cavities and the coronary arch. The liver was icteric and brownish-in-color, peritoneal and pleural fluid were also noted. The surface and cross section of the kidney revealed white-yellowish spots. In histopathological examination, the liver showed centralobular fatty change and necrosis, intralobular and interlobular hyperplasia with infiltration of lymphocytes and erthrophagocytosis by macrophages. Lymphoid follicles present in the cortex and medulla of the kidney. Hemosiderin was not found in the Turnbull blue test. |
