Abstract

Abstract : Background. Toxoplasmosis is caused by an intracellular parasite Toxoplasma gondii, which can infect many hosts including humans. Methods. In order to estimate whether dustmen are more susceptible to T. gondii, a case-control study was conducted containing 332 dustmen from Jilin and Heilongjiang in Northeastern China, as well as 332 general populations from the same regions as control subjects. Serum samples were tested IgG and IgM antibodies to T. gondii using the enzyme-linked immunosorbent assay (ELISA). Results. The overall anti- T. gondii IgG was 15.06% (50/332) in dustmen compared with 9.64% (32/332) in the controls ( P = 0.0337). Also, 5 (1.51%) dustmen had anti- T. gondii IgM antibodies compared with 2 (0.60%) control individuals ( P = 0.2543). A significant association was only found between dustmen and level of T. gondii IgG in comparison with the control subjects. Seroprevalence of T. gondii IgG antibodies in male dustmen was significant higher than male control subjects ( P = 0.0399). Dustmen from Jilin had the significant higher T. gondii IgG rate ( P = 0.0143), in comparison with the control subjects from Jilin. Moreover, dustmen raising cat at home had the significant higher T. gondii IgG rate ( P = 0.0097), in comparison with the control subjects. Risk factor analysis suggested that raising cat at home and not having habits of washing hand before eating were mainly related to the T. gondii infection in dustmen. Conclusions. This is the first record of seroprevalence of T. gondii infection in dustmen in Jilin and Heilongjiang provinces in Northeastern China. These findings also suggest that the government departments should pay close attention to the toxoplasmosis in dustmen in Northeastern China.
