[Serological survey of Toxoplasma gondii infection in some areas of Pu' er City].

OBJECTIVE

To understand the status of Toxoplasma gondii infection in the population of Pu'er City, so as to provide the evidence for formulating the strategy of toxoplasmosis control.

METHODS

The population from Jingdong, Jinggu, and Menglian counties in Pu' er City was surveyed; IgG of T. gondii in serum was detected by ELISA.

RESULTS

Totally 906 resident serum samples were detected and the IgG positive rate was 24.2%. The positive rates were higher in the aged groups of 30-39 years and 60-69 years, and the difference among different aged groups was significant (Χ2 = 17.77, P < 0.01). There were no significant differences between different sexualities, and among different educational levels and living habits (P > 0.05). The positive rates were 26.6% (194/730), 15.5% (22/142), and 8.8% (3/34) in farmers, students and other occupations, respectively, and there was a significant difference among them (Χ2 = 12.51, P < 0.01). The positive rates were 23.3% (198/849)and 36.8% (21/57) in the farmers who had the habit of rearing pigs in pens and the farmers who had the habit of free ranging pigs, respectively, and there was a significant difference between them (Χ2 = 5.33, P < 0.05).

CONCLUSION

The IgG positive rate of T. gondii is very high in Pu'er City, and therefore, the health education for toxoplasmosis control should be strengthened.
