引形虫广泛分布于世界各地,全球约有5～10亿人受弓形虫感染,欧美等国十分重视,法国将该病的血清检查列入法定的婚前必查项目。我国也开始了人群中弓形虫病血清学检查,据北京和天津某些地区的调查,血清阳性率分别为3.9%和23～38%,说明人体弓形虫感染并非少见。但在临床上发现的病例却很少,而实际上本病涉及内、儿、妇产、眼、神经、精神等临床各科,因此临床工作者必需提高对弓形虫病的认识,以减少漏诊和误诊,为此本文结合病理机制对弓形虫病的各种临床表现作一简要介绍,至于本病的流行病学、血清学诊断和防治原则,本人新近已有综述,不再在此重复。弓形虫病可分获得性和先天性两大类,它们的临床表现和预后很不相同,故分别予以叙述。 Caterpillars are widely distributed around the world. About 5-10 billion people worldwide are infected with toxoplasmosis. The United States, Europe and the United States attach great importance to this. The French government will include the serum screening of the disease in statutory premarital surveys. Toxoplasmosis serodiagnosis has also started in China. According to the survey in some areas of Beijing and Tianjin, the seroprevalence rates were 3.9% and 23-38%, respectively. This indicates that human Toxoplasma gondii infection is not uncommon. However, there are only a few cases found clinically. In fact, the disease involves clinical departments such as internal medicine, children, obstetrics and gynecology, ophthalmology, nerves and spirits. Therefore, clinicians must raise awareness of toxoplasmosis to reduce missed diagnosis And misdiagnosis, this article combined with the pathological mechanism of various clinical manifestations of toxoplasmosis make a brief introduction, as the epidemiology of the disease, serological diagnosis and prevention principles, I have recently reviewed, no longer repeat here. Toxoplasmosis can be divided into two major categories of acquired and congenital, their clinical manifestations and prognosis are very different, so were described.
