Epidemiology of Toxoplasma gondii infection in native Tibetans in Tibet, China

Abstract
Toxoplasma gondii (T. gondii) is one of the most common and widespread protozoan parasite which caused toxoplasma infection in animals and humans. Toxoplasma infection in healthy people is usually asymptomatic and it can lead to serious pathological effects in congenital cases and immunodeficient patients. The aim of the study is to investigate the prevalence of T. gondii infection in native Tibetans in Tibet as scarce information is available on such a high plateau. A total of 600 blood samples were collected from Tibetans people who visited the hospital in Nyingchi city with the history of flu, swollen lymph glands, muscle pain, and neurological or eyes complications (showing single or more signs). The serum of collected samples were tested for IgG antibody by ELISA. The result showed that the prevalence in men and women were 11.3% and 11.0%, respectively, the prevalence in different ages were 9.8% in < 7 years, 6.2% in ≥7–17 years, 10.1% in ≥18–40 years, 14.8% in ≥41–65 years and 11.6% in ≥66 years. The current study indicates the first report of this zoonotic parasite infection in Tibetan people.
