Methods A total of 337 patients with type 1 diabetes mellitus, 624 patients with type 2 diabetes mellitus and 384 patients with gestational diabetes mellitus living in Hangzhou City during the period from March 2017 through May 2020 were recruited as the study subjects, while age⁃ and gender⁃matched healthy volunteers and pregnant women without gestational diabetes mellitus served as controls. Enzyme⁃linked immunosorbent assay (ELISA) was employed to detect serum IgG and IgM antibodies against T. gondii in patients with diabetes mellitus and controls, and the seroprevalence of anti⁃T. gondii antibody was compared between diabetes mellitus patients and controls. Results The overall seroprevalence of anti⁃T. gondii antibody(18.10% vs. 4.45%, [χ2] = 31.38, P < 0.01) and the seroprevalence of anti⁃T. gondii IgG antibody (14.54% vs. 2.97%, [χ2] = 28.28, P < 0.01) were both significantly higher in patients with type 1 diabetes mellitus than in healthy controls, while no significant difference was seen in the seroprevalence of anti⁃T. gondii IgM antibody between patients and controls (3.56% vs. 1.48%, [χ2] = 2.96, P > 0.05). The seroprevalence rates of serum anti⁃T. gondii (23.56% vs. 6.57%, [χ2] = 70.37, P < 0.01) and anti⁃T. gondii IgG antibodies (21.15% vs. 5.45%, [χ2] = 66.73, P < 0.01) were significantly higher in patients with type 2 diabetes mellitus than in healthy controls, while no significant difference was seen in the seroprevalence of anti⁃T. gondii IgM antibody between patients and controls (2.40% vs. 1.12%, [χ2] = 2.96, P > 0.05). In addition, the overall seroprevalence of serum anti⁃T. gondii antibody(26.30% vs. 19.53%, [χ2] = 4.98, P < 0.05) and the seroprevalence of anti⁃T. gondii IgG antibody (23.70% vs. 17.71%, [χ2] = 4.20, P < 0.05) were both significantly higher in patients with gestational diabetes mellitus than in pregnant women without gestational diabetes mellitus, while no significant difference was seen in the seroprevalence of anti⁃T. gondii IgM antibody between pregnant women with and without gestational diabetes mellitus (2.60% vs. 1.82%, [χ2] = 0.54, P > 0.05). Conclusions The patients with diabetes mellitus present a higher seroprevalence rate of anti⁃T. gondii antibody than controls in Hangzhou City. Screening of T. gondii infections and health education pertaining to toxoplasmosis prevention and control knowledge should be reinforced in patients with diabetes mellitus. %U https://www.zgxfzz.com/EN/abstract/article_11232.shtml
