Objectives: Toxoplasmosis is caused by Toxoplasma gondii. 50 to 70% of African are contaminated and 60% to 80% in Togo. This parasitic infection involves disorders in immunocompromised persons and pregnant women. The purpose of this study is to evaluate the seroprevalence of toxoplasmosis and the risk factors of contamination in the Togolese population. Methods: Prospective studies from January 2012 to December 2015 concerned 7076 patients. A survey on the risk factors for Toxoplasma gondii contamination has done. The seroprevalence was monitored by examining serological antibodies IgG and IgM using ELISA method. Sampling of 200 excreta of domestic cats were analyzed by coproscopy examinations Results: The average age was 32.61±6.80 years old. The seroprevalence of IgM was 2.85%; and for IgG 59.7%. IgG were high in men (67.0% vs. 58.6%, p<0.0001); IgM were high in women (2.81% vs. 1.85%, p<0.01). In this study, we observed 57.49% immunized subjects. Regarding potential risk factors for contamination, the survey revealed that 80.5% of subjects consume raw garden produce, 65.4% non-potable and 8.3%  undercooked meat. In cats, 20.5% of them excreted oocysts of Toxoplasma gondii. Conclusion: The prevalence of the toxoplasmosis was high in the Togolese population because the risks factors were variable and the level of contamination were high too. The country’s health authorities, especially for the pregnant women, should install sensitization and prevention programs on the risks of the contamination of toxoplasmosis. The high proportion of the young subjects affected constitutes a socio-economical danger for the country.

Abstract Background Toxoplasmosis is caused by infection with the protozoan parasite Toxoplasma gondii. It is acquired by consumption of raw or undercooked meat containing tissue cyst, food or water contaminated with oocyst and congenital infection through the placenta leading to serious congenital abnormalities in the fetus like miscarriage, stillbirth, intrauterine death and neurologic defects. Therefore; this study was aimed to determine the prevalence of toxoplasmosis infection and its possible risk factors associated with pregnant women attending antenatal clinics in Hawassa and Yiregalem Hospitals, Southern Ethiopia. Methods A hospital-based cross-sectional study was conducted from December 2016 to May 2017. The study was done in antenatal care clinics of Hawassa and Yiregalem Hospitals in Southern, Ethiopia. Five hundred pregnant women were interviewed with a pretested structured questionnaire to collect risk factors and socio-demographic data. Blood samples were collected and serum was separated and tested for anti- Toxoplasma gondii antibodies using ELISA (Enzyme-linked Immunosorbent Assay). Data were analyzed using SPSS version 20 statistical software. The risk factors were tested for significance using Bivariate and multivariate analysis. P-value < 0.05 was considered statistically significant. Results The weighted prevalence of this study was 81.8% for the anti- Toxoplasma gondii antibody. Almost all participants (99.6%) had no information about the disease. A significant association was observed between seroprevalence and contact with domestic cats (OR = 1.206, 95% CI (1.627–2.206, P = 0.043), consumption of raw meat (OR = 0.848, 95% CI: 1.517–2.941, P = 0.019) and unpasteurized milk (OR = 0.871, 95% CI 1.531–2.221, P = 0.032). A significant association was not observed between seroprevalence and age, history of abortion, and blood transfusion. Conclusions The findings of this study demonstrated a relatively higher prevalence of seropositivity than studies reported from other countries. Existence of domestic cats at home, consumption of undercooked meat and unpasteurized milk were identified as risk factors for T. gondii infection. Therefore, a health education program to increase the mother’s knowledge about toxoplasmosis towards avoiding eating undercooked meat, contact with cats and consumption of unpasteurized milk during pregnancy is recommended. Furthermore, our results suggested that the implementation of newborn screening and follow-up testing can lead to reducing of toxoplasmosis associated complications.

Background Toxoplasma gondii is an obligate intracellular and neurotropic apicomplexan protozoan parasite infecting almost all warm-blooded vertebrates including humans. To date in Ethiopia, no systematic study has been investigated on the overall effects of potential risk factors associated with seropositivity for Toxoplasma gondii among pregnant women and HIV infected individuals. We intended to determine the potential risk factors (PRFs) associated with seropositivity for Toxoplasma gondii from published data among pregnant women and HIV infected individuals of Ethiopia. Methodology An systematic review of the previous reports was made. We searched PubMed, Science Direct, African Journals Online, and Google Scholar for studies with no restriction on the year of publication. All references were screened independently in duplicate and were included if they presented data on at least two risk factors. Meta-analysis using the random or fixed-effects model was made to calculate the overall effects for each exposure. Results Of the 216 records identified, twenty-four reports met our eligibility criteria, with a total of 6003 individuals (4356 pregnant women and 1647 HIV infected individuals). The pooled prevalences of anti-Toxoplasma gondii antibodies were found at 72.5% (95% CI: 58.7% - 83.1%) in pregnant women and 85.7% (95% CI: 76.3% - 91.8%) in HIV infected individuals. A significant overall effect of anti-Toxoplasma gondii seropositivity among pregnant women (p < 0.05) was witnessed with age, abortion history, contact with cats, cat ownership, having knowledge about toxoplasmosis, being a housewife and having unsafe water source. Age, cat ownership, and raw meat consumption were also shown a significant effect (p < 0.05) to anti-Toxoplasma gondii seropositivity among HIV infected individuals. Conclusions This review showed gaps and drawbacks in the earlier studies that are useful to keep in mind to design accurate investigations in the future. The pooled prevalence of anti-Toxoplasma gondii antibodies was found to be higher among pregnant women and HIV infected individuals. This suggests that thousands of immunocompromised individuals (pregnant women and HIV infected patients) are at risk of toxoplasmosis due to the sociocultural and living standards of the communities of Ethiopia. Appropriate preventive measures are needed to reduce the exposure to Toxoplasma gondii infection. Further studies to investigate important risk factors are recommended to support the development of more cost-effective preventive strategies.

Recently has been observed globally that toxoplasmosis disease was caused by Toxoplasma gondii and generally its asymptomatic infection in people except pregnant women. Many previous studies were suggested this pathogen transmits by ingesting of undercooked or raw meat contaminated with the oocytes of this parasite. The study aimed to show the seroreactivity of Toxoplasma gondii antibodies among pregnant women and to evaluate association of studied risk factors with infected cases. ELISA technique used for detection of anti-toxoplasma specific IgG and IgM antibodies. A biography form interview for participant was performed to estimate between the risk factors and  toxoplasmosis. The present study was carried out from the beginning of October 2018 to the end of March 2019 and included 90 pregnant women visited Akre general hospital. Out of 90 tested samples, 49 (54.46%) and 4 (4.44%) were positive for IgG and IgM respectively. According to residency factor, pregnant women from villages had higher percentages of IgG (57.14%) and IgM (4.08%) than those lived in the city which were recorded 0% and 48.48%of IgM and IgG respectively. A high percentage of IgG (65.64%) and IgM (7.27%) were found among pregnant women with history of miscarriage. Seropositivity for both IgG (61.90 %) and IgM (9.52%) was higher among pregnant women who had cats compared to those without cat. Seroprevalence of IgM and IgG was 9.67% and 54.83% among population who had undercooked meat, while 1.69% and 59.23% were positive for IgM and IgG respectively, in those well cooked meat meal. Highest positive percentage of IgG (77.77%) was recorded at ages 40-50 years while the lowest rate was (40%) at ages <20 year. Through a seropositive reaction was found that age groups as a possible risk factor by ELISA IgG in which risk increased by rising of age categories. Significant correlation was detected between consumption of undercooked meat and cases positive for IgM. It revealed the association between third trimester and cases with positive IgM. In the conclusion, toxoplasmosis is widespread in the area which requires raising awareness among pregnant women to decrease T. gondii infection and subsequently minimize possibilities of congenital transmission.

SUMMARYIn this study we determined the presence of IgM/IgG antibodies toToxoplasma gondiiin sera of 155 and 300 pregnant women from Lisbon (Portugal) and Luanda (Angola), respectively, and evaluated the potential risk factors associated with this infection. DNA detection was performed by PCR assays targetingT. gondiiregions (RE/B1). Overall, 21·9% (10·9% IgG, 10·9% IgG/IgM) of the Lisbon women and 27·3% (23·7%, IgG, 2% IgM, 1·7% IgG/IgM) of the Luanda women had antibodies toT. gondii. Single variable and binary logistic regression analyses were conducted. Based on the latter, contacts with cats (family/friends), and having more than two births were identified as risk factors forToxoplasmainfection in Lisbon women. In Luanda, the risk factors forT. gondiiinfection suggested by the single variable analysis (outdoor contact with cats and consumption of pasteurized milk/dairy products) were not confirmed by binary logistic regression. This study shows original data from Angola, and updated data from Portugal in the study of infection byT. gondiiin pregnant women, indicating that the prevalence of anti-Toxoplasmaantibodies is high enough to alert the government health authorities and implement appropriate measures to control this infection.

We report the case of a 69-year-old man, who presented in the UK with a short history of deteriorating vision and clinical features of bilateral atypical retinochoroiditis, after travelling to South America. Vitreous samples demonstrated Toxoplasma gondii DNA by PCR. Serology tests demonstrated recent acquired Toxoplasma gondii infection with IgM antibodies. He responded well to treatment with trimethoprim-sulfamethoxazole, azithromycin and oral steroids.This case is a reminder of the global importance of Toxoplasma related eye disease, and its uncommon bilateral severe presentation in a returning traveller, where the risk factors were age and the route of infection likely to be a virulent parasite oocyst from vegetables or water rather than undercooked meat or direct contact with cats.

Toxoplasmosis is a parasitic infection caused by Toxoplasma gondii. Both animals and humans could develop the infection through several ways including diet, unhygienic habits, direct contact to soil, blood transfusions and organ grafting. Although all people are at risk of the infection, ones with weakened immune systems are at much higher risk, out of these are cancer patients, pregnant women, fetuses and newborns. In our study, we collected data from three gynecologists in two Lebanese regions in order to evaluate the prevalence of the infection and the risk factors associated with it. We found out that the increase in age and pet ownership is directly correlated with the number of infected women and the infection of the women is directly related to the mode of delivery being c-section and having infected offspring.

AbstractToxoplasmosis is a parasitic zoonotic disease caused by Toxoplasma (T.) gondii. Limited data are available on the occurrence of T. gondii in women especially pregnant women in Pakistan. The present study aimed to determine the occurrence and risk factors associated with T. gondii in pregnant and non-pregnant women in Punjab Province, Pakistan. A cross-sectional study was conducted and 593 samples were collected from pregnant (n = 293) and non-pregnant (n = 300) women of District Headquarter Hospitals of Chiniot, Faisalabad, Jhang and Okara, Pakistan. Data related to demographic parameters and risk factors were collected using a pretested questionnaire on blood sampling day. Serum samples were screened for antibodies (IgG) against T. gondii using ELISA. A univariant and binomial logistic regression was applied to estimate the association between seropositive and explanatory variables considering the 95% confidence interval. P value ⩽0.05 was considered statistically significant for all analysis. Out of 593, 44 (7.42%) women were seropositive for T. gondii IgG antibodies. Occupation, age, sampling location, socioeconomic status, contact with cat, pregnancy status and trimester of pregnancy were significantly associated with seropositivity for T. gondii antibodies. Location and trimester of pregnancy were identified as potential risk factors for T. gondii seropositivity based on binomial logistic regression. Toxoplasma gondii is prevalent in pregnant and non-pregnant women. Therefore, now a necessitated awareness is required to instruct the individuals about these infectious diseases (toxoplasmosis) and their control strategies to maintain the health of human population. Moreover, health awareness among public can help the minimization of T. gondii infection during pregnancy and subsequent risk of congenital toxoplasmosis.
