弓形虫是一种机会致病性原虫，而恶性肿瘤患者的免疫功能低下，易致感染。有关恶性肿瘤患者感染弓形虫的调查，文献已有不少报道，但来自亚热带的粤西地区恶性肿瘤患者感染弓形虫的文献未见报道。为此，我们采用间接红细胞凝集试验（IHA）及酶联免疫吸附试验（ELISA），检测了1

There have been many reports on the investigation of Toxoplasma gondii infection in patients with malignant tumors. However, no reports have been reported on the infection of Toxoplasma gondii in patients with malignant tumors from the subtropics of western Guangdong.
