“…Some previous reports indicated that the seropositivity of T. gondii was related to age [9,10]. Consistent with these studies, the present study showed highly significant differences in T. gondii seropositivity in the different age groups (18-45, 45-65, >65 years) in the two ethnic populations.…”

Eating raw pork and/or liver is a custom of the Bai ethnic group in China. Most people living in Dali Bai Autonomous Prefecture, Yunnan Province, southwestern China are of Bai ethnicity. Little is known of the seroprevalence of Toxoplasma gondii in Bai and Han ethnic populations in this region. In the present survey, a total of 555 and 595 blood samples were obtained from Bai and Han ethnic groups in Dali urban and rural areas, respectively. Enzyme-linked immunosorbent assay was performed to examine T. gondii IgG antibodies. Total positive rate of anti-T. gondii IgG in Bai and Han groups in this region was 21·6% (248/1150). The total seroprevalence of T. gondii was significantly higher in the Bai ethnic group (32·3%, 179/555) than in the Han ethnic group (11·6%, 69/595) (P < 0·01). The results of statistical analysis indicated that there was no significant difference between cat feeding/non-cat feeding groups in the Bai ethnic group, the most important risk factor was consumption of raw pork and/or liver for the Bai group, but feeding a cat may be the main route of T. gondii infection for the Han group. Therefore, it is essential to implement integrated strategies to prevent and control T. gondii infection in this unique region of the world.

“…Regarding demographic characteristics, the T. gondii seroprevalence found in the present study was not significantly associated with any of the sociodemographic characteristics of the psychiatric patients. It has been reported that seropositivity to T. gondii is related to age [11][12][13]; however, in the present investigation, T. gondii infection in psychiatric patients was not significantly influenced by age. Although high seropositivity to T. gondii was found in the 70-79 and 580 years age groups of psychiatric patients, the number of subjects in age groups 60-69, 70-79 and 580 years was limited in this study.…”

Seroprevalence and associated risk factors ofToxoplasma gondiiinfection in psychiatric patients: a case-control study in eastern China

In recent years, the effect of Toxoplasma gondii infection on the cerebrum and neuropsychiatric patients has been increasingly highlighted. However, there is limited information about the epidemiology of T. gondii infection in psychiatric patients in Shandong province, eastern China. Therefore, through a case-control study, 445 patients hospitalized for diacrisis or treatment in Weihai, eastern China, and 445 control subjects from the general population of the same region matched by gender, age, and residence were examined with enzyme-linked immunoassays for the presence of IgG and IgM antibodies to T. gondii and associated sociodemographic and behavioural characteristics in a population of psychiatric patients. Seroprevalence of IgG antibodies to T. gondii in psychiatric patients (77/445, 17·30%) was significantly higher than in control subjects (55/445, 12·36%) (P = 0·038). Fourteen (3·15%) psychiatric patients and 10 (2·25%) control subjects had IgM antibodies to T. gondii (P = 0·408). Multivariate analysis using logic regression showed that T. gondii infection was associated with cats at home and consumption of raw/undercooked meat in psychiatric patients. Considering that most psychiatric patients usually have lower cognitive functioning and additional transmission routes related to their inappropriate behaviours that could enhance the risk of infection, psychiatric patients should be considered as a specific group of T. gondii infection.

“…One out of every three farmworker families consumed the infected meat of their animals. Consumption of infected animal meat might be a threat for toxoplasmosis transmission; it has been reported that tissue cysts are mostly detected in the intercostal, leg, and diaphragmatic muscles of sheep and poultry, which are frequently consumed by humans and have been implicated as an important source of toxoplasmosis [20,21] In this study, we found that increasing age was associated with the seropositivity of T. gondii, which was reported previously in other studies [22][23][24][25][26][27]. This might be explained by longer exposure to risk factors and by the transmission methods of T. gondii.…”

Introduction: There are a limited number of studies of the agricultural population about the prevalence of Toxoplasma gondii (T. gondii) infection throughout the world. The aim of this study was to determine the prevalence and risk factors of toxoplasmosis in female farmworkers in the southeastern region of Turkey. Methodology: The optimum sample size was determined using the Epi Info Program, and blood samples were collected from 684 women of reproductive age. Serum samples were analyzed by qualitative and quantitative methods for anti-T. gondii IgG and IgM antibodies with a commercially available enzyme immunoassay. Questionnaires through which socio-demographic information was collected were applied during face-to-face interviews of subjects who gave their consent to participate in the study. Crude odds ratios (ORs) and 95% confidence intervals (CIs) were calculated, and Chi-square analyses and logistic regression were performed. Results: Of the 684 women, the prevalence of toxoplasmosis was determined to be 58.3% and 1% for IgG and IgM, respectively. Employment as a seasonal farmworker, increasing age, and having had three or more pregnancies were found to be the crucial associated risk factors that affect the prevalence of T. gondii infection (p < 0.05). In contrast to these, the provincial development level was found to be a confounding factor. There was no association between toxoplasmosis and household size, education attainment, and poverty in the bivariate analyses. Conclusions: The findings show that control and serological screening programs should be implemented nationwide in Turkey for the reliable and fast detection of congenital Toxoplasma infections.
