Toxoplasma gondii is an obligate intracellular protozoan that can infect all kind of birds and all mammals including humans and is common throughout the world. The prevalence varies according to social and cultural habits, pet cats in homes and geographic factors. Domestic cats are considered to be an important source of Toxoplasma gondii infection. From January to June 2006, the prevalence of toxoplasmosis was retrospectively monitored from blood samples that had been sent to our laboratory in order to determine the levels of IgM and IgG. All the subjects were women and 2,586 blood samples were investigated with the chemiluminescence immunoassay method. The rates of Toxoplasma gondii IgM antibodies were found to be 3.0% (78/2,586) and that of Toxoplasma gondii IgG antibodies, 69.5% (1.798/2,586). The total rate of positivity of Toxoplasma gondii antibodies was 69.6% (1,801/2,586) and the negativity, 30.4% (785/2,586). The highest positive rates have been reported in the southeastern region of Turkey and the 69.6% detected in our study seems to be the highest rate. Raw meatball consumption is common in our region and raw meat has a high risk of Toxoplasma gondii infection by direct ingestion of tissue cysts. As a result we consider that the high frequency of Toxoplasma gondii seropositivity in this region is due to raw meatball consumption.
弓形虫是一种专性细胞内原生动物,可感染包括人类在内的所有鸟类和所有哺乳动物,在全球范围内都很常见。其流行率因社会文化习惯、家庭养猫情况和地理因素而异。家猫被认为是弓形虫感染的重要来源。2006年1月至6月,为了确定IgM和IgG水平,我们对送至实验室的血液样本进行回顾性监测,以了解弓形虫病的流行情况。所有受试者均为女性,共2586份血液样本采用化学发光免疫分析法进行检测。结果发现,弓形虫IgM抗体阳性率为3.0%(78/2586),弓形虫IgG抗体阳性率为69.5%(1798/2586)。弓形虫抗体总阳性率为69.6%(1801/2586),阴性率为30.4%(785/2586)。据报道,土耳其东南部地区的阳性率最高,而我们研究中检测到的69.6%似乎是最高比例。在我们地区,食用生肉丸很常见,而生肉通过直接摄入组织包囊有很高的感染弓形虫的风险。因此,我们认为该地区弓形虫血清阳性率高是由于食用生肉丸所致。
