“…Surprisingly, in the present study, there was a non-statistically significant increase in seropositivity of anti-T. gondii antibody with age of study participants. However, the observation is in agreement with other similar studies in which increasing age was more associated with chronic infection (Rosso et al, 2008, Al-Mohammad et al, 2010Markovich et al, 2014). This could be explained by the fact that older women are more likely to have been exposed much longer to any one of the risk factors than younger women.…”

Background: Toxoplasma gondii infection in pregnancy, if left untreated, is associated with spontaneous abortions, low birth weight babies, congenital deformities and intrauterine deaths. The infection is also associated with human immune deficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). In Rwanda, the burden and risk factors of T. gondii infection among pregnant women and among HIV infected pregnant women is largely unknown. This cross-sectional study aimed at determining the seroprevalence of T. gondii infections and their risk factors among pregnant women in Kigali, Rwanda. Methods: Pregnant women aged 18 years and above who were attending antenatal care at four clinics in Kigali City, between April and August 2014 were screened for IgG and IgM antibodies against T. gondii using ELISA technique. Information on their HIV status and CD4 + cell count was obtained from their medical records. Participants were also interviewed on selected behaviours that predispose individuals to T. gondii infection. Results: A total of 384 pregnant women were involved in the study. The overall T. gondii seroprevalence was 12.2%. Of the 384 pregnant women studied, 37 (9.6%) were positive for anti-T.

“…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.…”

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.
