Toxoplasma gondii infection in patients with lung diseases in Shandong province, eastern China. Acta Trop. 2020 Jun 03;:105554 Authors: Li YX, Wei CY, Zhang XY, Duan YH, Zhang PN, Guo MJ, Niu HT Abstract Toxoplasma gondii, an intracellular protozoan parasite, can induce various clinical symptoms. T. gondii has been considered to play an important role in the pathogenesis of lung diseases. This survey was conducted to explore the correlation between T. gondii infection and lung diseases through a case-control study carried out in Shandong province, eastern China. In the present survey, T. gondii IgG antibodies were found in 76/398 (19.10%) of patients with lung diseases, which was significantly higher (P < 0.001) than the level found in the control subjects (35/398; 8.79%) through serological diagnosis. Patients with lung cancer have the highest T. gondii seroprevalence (26.19%), followed by Pulmonary cyst (25.00%), Tuberculosis (17.07%), Pneumonia (16.33%) and chronic obstructive pulmonary disease (COPD) (16.05%). Moreover, a semi-nest PCR targeted T. gondii B1 gene was employed to detect the T. gondii DNA in the blood samples. T. gondii DNA was detected in 5.53% blood samples of patients with lung diseases and 2.51% control subjects, respectively. The present study firstly shows that T. gondii has a high probability to infect the patients with lung diseases. Thus, the potential presence of T. gondii in patients with lung diseases...
