摘要: 剖腹后,将多栖培养的溶组织内阿米巴滋养体接种到长爪沙鼠盲肠内。接种后7~20d检查受试动物的肠内容物及肠、肝、脾、肠系膜淋巴结的病理组织学变化。16只受试动物有12只受染,其中7只出现盲肠病变,主要表现为粘膜表面縻烂,肠壁各层均有巨噬细胞和淋巴细胞浸润。其中1鼠的肠系膜淋巴结出现小灶状坏死,肝脏出现多发性小阿米巴脓肿。

Abstract: Polyxenically cultivated Entamoeba histolytica trophozoites(HB1 and HT1 strains)were inoculated into the cecum of the clawed jirds (Meriones unguiculatus) after laparotomy.The histopathological changes occurred in the colon,liver,spleen and mesenteric lymph nodes of the jirds were studied from 7 to 20 days postinoculation.Of 16 inoculated jirds,12 were infected.Seven of the infected jirds showed early invasive lesions with superficial ulcerations and lymphocytic and giant cell infiltrations in every layer of the intestinal wall.Small amebic liver abscess and small focal necrosis in the mesenteric lymph nodes were found in one jird.
