SUMMARYToxoplasmosis is a worldwide zoonosis due to Toxoplasma gondii, a ubiquitous protozoan parasite of warm-blooded animals including humans. In pregnant women, primary infection can cause congenital toxoplasmosis resulting in severe malformations in the newborn. Since 1978, public health authorities in France have implemented a congenital toxoplasmosis prevention programme, including monthly serological screening of all seronegative pregnant women, and treatment in case of seroconversion. However, this programme does not produce systematic surveillance data on incidence and prevalence. Our objective was to estimate the incidence and prevalence of T. gondii infection, and the incidence of seroconversion during pregnancy in women in France. We used a catalytic model to estimate incidence and prevalence of Toxoplasma infection between 1980 and 2020 in women of childbearing age. We used age- and time-specific seroprevalence data obtained from the National Perinatal Surveys (NPS) conducted in 1995, 2003 and 2010. We assumed that incidence depends both on age and calendar time, and can be expressed as the product of two unknown functions. We also estimated incidence of seroconversion during pregnancy in 2010 from the NPS and the National Surveillance of Congenital Toxoplasmosis (ToxoSurv). We combined data of 42208 women aged 15–45 years with serology available from the three NPS. For women aged 30 years the modelled incidence decreased from 7·5/1000 susceptible women in 1980 to 3·5/1000 in 2000. In 2010 the incidence was 2·4/1000. The predicted incidence and prevalence for 2020 was 1·6/1000 and 27%, respectively. The incidence of seroconversion during pregnancy in 2010 was estimated at 2·1/1000 susceptible pregnant women (95% CI 1·3–3·1) from the NPS and 1·9 (95% CI 1·8–2·1) from ToxoSurv. Incidence and prevalence of Toxoplasma infection has decreased markedly during the last 30 years. This decrease may be explained by a lower exposure to the parasite by changes in food habits and by improved hygiene practices in meat production. Modelled estimations were consistent with estimates observed in other studies conducted previously in France. The catalytic modelling provides reliable estimates of incidence and prevalence of Toxoplasma infection over time. This approach might be useful for evaluating preventive programme for toxoplasmosis.

SUMMARYToxoplasmosis caused by the protozoan parasite, Toxoplasma gondii, is a worldwide zoonosis. In this paper published information on toxoplasmosis in humans and other animals in Ethiopia is reviewed. Limited data indicate that the prevalence of T. gondii in humans in Ethiopia is very high, up to 41% of children aged 1–5 years were reported to be seropositive. There is little information on seroprevalence data in pregnant women and no data on congenital toxoplasmosis in children. About 1 million adults in Ethiopia are considered to be infected with HIV with less than one-third likely receive highly active antiviral therapy. Based on a conservative T. gondii seroprevalence of 50%, thousands might die of concurrent opportunistic infections, including toxoplasmosis. However, exact figures are not available, and most serological surveys are not current. Serological surveys indicate up to 79% of goats and sheep have T. gondii antibodies. However, there is no information on losses due to toxoplasmosis in livestock or the presence of viable T. gondii in any host in Ethiopia.

Toxoplasmosis is a disease that can infect animals and zoonotic in humans. In pregnant women (congenital toxoplasmosis), the risk and severity of symptoms of congenital toxoplasmosis are more severe if infection occurs early in pregnancy and asymptomatic. The only way to determine disease is by serological screening. Serological diagnosis techniques for toxoplasmosis include ELISA (Enzyme-linked Immunosorbent Assay) and ICT (Immunochromatography Assay Test). However, until now, research on toxoplasmosis with the ICT method is still minimal. This study aims to analyze the results of the IgM antibody examination Toxoplasma gondii using the ICT method with the ELISA method and calculate the sensitivity and specificity of the ICT method and the ELISA method in pregnant women. The research design was used analytic (cross-sectional), with the number of samples is 33 serums. Data from the ELISA method obtained from secondary medical record data and the remaining serum samples were examined by the ICT method by researchers at the Harapan Kita Hospital Laboratory. In the ICT method, two samples (6.1%) were positive, and 31 samples (93.9%) were negative. In the ELISA method, results obtained similar to the ICT method, two samples (6.1%) positive and 31 samples (93.9%) with negative results. Toxoplasmosis examination can be done using the ICT method as the initial serological screening stage, but it not recommended as a diagnosis enforcer.

Introduction Toxoplasmosis is an acute infectious anthropozoonotic disease with mild asymptomatic clinical manifestations in immunocompetent persons and more severe in immunocompromised patients. Acute infection in pregnancy can result in severe congenital toxoplasmosis with severe sequels. Objective Aims of study were to detect Toxoplasma gondii seroprevalence in general population of Vojvodina, Serbia, differences between genders and determination of seroprevalence in women of reproductive age and pregnant women. Methods Our retrospective study was conducted from 2006 to 2008 including 625 immunocompetent patients, hospitalized or observed as outpatients at the Clinical Centre of Vojvodina, Novi Sad. We performed commercial ELISA kits SERION - ELISA classic test by VIRION for the presence of specific IgG and IgM antibodies. According to seroepidemiological aim of the study, our results were presented only in qualitative values. Results We observed 173 male and 452 female patients. Seroprevalence in general population of Vojvodina was 38.1%. In male population seroprevalence was 45.7%, and in female population it was 35.2%, the difference which was statistically significant (p<0.05). Seroprevalence increased with age and seroconversion was detected to occur in persons aged about 20 years. In all female patients, 353 (78.1%) were in reproductive age with seroprevalence of 30%. In 161 pregnant women seroprevalence was 31.7%. Conclusion In this study we screened actual seroepidemiological situation to Toxoplasma gondii in Vojvodina, thus giving a contribution to the continuous epidemiological screening done in this region and in the country. According to our results, almost 70% of women in reproductive age were sensitive to primary acute infection during further pregnancies, which is highly important for the prevention of congenital toxoplasmosis. Although not routinely conducted in many countries, routine serological testing to Toxoplasma gondii in pregnant women and their education about preventive measures against this infection could be an effective measure in the future.

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.

SUMMARYSeroprevalence data from a representative population were used to estimate the annual incidence of congenital toxoplasmosis in São Paulo Metropolitan Region (SPMR). Retrospective anti-toxoplasma IgG serological analysis was conducted to determine age-dependent seroprevalence, force of infection, average age of acquisition of infection and curve of decay of maternally derived antibodies. Seroprevalence was used to calculate the number of new infections. Toxoplasmosis in pregnant women was estimated by total number of deliveries in a given year as a proxy for the number of pregnancies per year. Toxoplasma seroprevalence was 64·9% in women of childbearing age. Average age of acquisition of toxoplasmosis was 10·74 years. The estimated annual incidence of congenital toxoplasmosis varied from 9·5 to 10·6/1000 births in the studied period. The toxoplasmosis seroprevalence model allowed a good incidence estimation of congenital disease in SPMR compared to other published data, indicating that this mathematical approach is useful in calculating the potential demand of congenital disease due to Toxoplasma gondii in a given community.

Pregnant Mothers

The protozoan parasite, Toxoplasma gondii is estimated to infect one-third of the world’s population. Infection in pregnant women can cause severe conditions for their babies. Until now, there is no data regarding Toxoplasma infection from Makassar pregnant mothers. This study aims to obtain information on Toxoplasma specific antibodies and to measure the risk factor associate with parasite infection. This cross-sectional study conducted in 9 of 47 primary health centres (Puskesmas) in Makassar. Blood samples and questionnaires were collected from 184 pregnant women aged 15–42 years old from September to October 2020. ELISA technique was used to examine the IgG and IgM antibodies. Univariable and multivariable analyses were carried out to measure factors that independently associate with Toxoplasma antibody positivity. Our result showed the range of Toxoplasma IgM and IgG are 0.06–1.01 and 0.09–3.01, respectively. While no one of our participants has an acute Toxoplasma gondii infection (IgM positive), we found 32,6% pregnant mothers are exposed to parasite (positive IgG). Contact with cats [OR(95%CI): 10.45(3.77–28.99)], consume chicken satay [OR(95%CI): 9.72(3.71–25.48)] and consume un-boiled water/ filtered water [OR(95%CI): 5.98(1.77–20.23)] are independently associate with positive Toxoplasma IgG antibody. Based on the result, we conclude that pregnant women in Makassar are exposed to T. gondii and the oocyst and tissue cyst of parasite contaminates food and water in Makassar.

The Impact

Background: Toxoplasma gondii is an obligate, intracellular, apicomplexan parasite that causes toxoplasmosis. Although the global prevalence of toxoplasmosis has been estimated to be approximately 30%, there is limited seroprevalence data in Ghana, with a dearth of information on the impact of T. gondii on haematological parameters in exposed persons. Methods: Questionnaires were administered to 300 consenting individuals to obtain demographic information and assessment of their risk of exposure to T. gondii. Using anti- T. gondii IgG/IgM combo test kits, seropositivity to parasite-specific IgG and/or IgM was determined. A haematological analyser was used to measure haematological parameters. Results: There was an overall seroprevalence of 50.3% (n=151), with 49.7% (n=149) of the study participants seropositive for IgG and 1% (n=3) testing positive for IgM. Furthermore, the observed seroprevalence among pregnant women was 56.4% (n=62). With regard to settlement type, a seroprevalence of 55.6% was observed in the rural community, 50.6% in the peri-urban community and 47.1% in the urban community. The study identified cat ownership, contact with cat litter, contact with raw meat  [RR (95% CI: 1.76 (1.23-2.53), 1.66 (1.03-2.67), 1.25(1.00-1.57)] and age (p<0.001) as risk factors for infection. Analyses of haematological data revealed significant reduction in the white blood cell, lymphocytes and mean corpuscular volume levels in seropositive males (p=0.0223, 0.0275, and 0.0271) respectively. Only the mean corpuscular volume of seropositive females reduced significantly as compared to the seronegative counterparts (p=0.0035).  Conclusions: About half of the study population, including women of reproductive age carried antibodies against T. gondii, raising concerns about the risk of congenital toxoplasmosis and anaemia. We, therefore, recommend that screening for Toxoplasma gondii be included in the routine screening of pregnant women seeking antenatal care and further investigation should be conducted on the haematological implications of infection in humans.

Toxoplasma Gondii Infection

Toxoplasma gondii is a widely prevalent protozoan parasite in human populations. This parasite is thought to be primarily transmitted through undercooked meat and contamination by cat feces. Here, we demonstrate that Toxoplasma gondii cysts can be found within human semen, thus suggesting a potential for sexual transmission. We visualized Toxoplasma gondii cysts in ejaculates of immune-competent and latently infected human volunteers. We confirmed the encystment by probing transcription of a bradyzoite-specific gene in these structures. These observations extend previous observations of the parasite in semen of several non-human host species, including rats, dogs, and sheep. Toxoplasma gondii infection is a clinically significant infection, in view of its high prevalence, its purported role in neuropsychiatric disorders such as schizophrenia, as well as in the more serious form of congenital toxoplasmosis. Our demonstration of intact Toxoplasma gondii cysts in the ejaculate supports the possibility of sexual transmission of the parasite and provides an impetus for further investigations.

Underlying Risk

Toxoplasma gondii is a ubiquitous intracellular parasite, which is commonly known to infect all warm-blooded animals. Almost 30 % of the world’s human population is infected with this parasite, though the infection varies depending on the region and ethnic group. Also, almost half of pregnant women in Morocco and one-third in Palestine have been infected with toxoplasmosis. Several studies have been conducted in order to estimate the prevalence of this parasite among pregnant women in Morocco and Palestine. However, studies revolving around the occurrence of this parasite among livestock and the environment in Palestine and Morocco are inadequate. This review will shed light on the underlying risk factors associated with the prevalence of this parasite by drawing on a comparison between the occurrence of toxoplasmosis in two different countries. It also intends on increasing the awareness and knowledge regarding this parasite among the general population. Nonetheless, Congenital toxoplasmosis as well as the seroprevalence of Toxoplasmosis among women who have undergone abortion still need to be studied further, particularly in Morocco.
