Toxoplasma gondii is a common protozoan parasite that can cause serious outcomes, especially during pregnancy, including miscarriage, stillbirth, preterm birth, and congenital abnormalities. This study was designed to determine the seroprevalence of T. gondii and explore associated risk factors among women with a history of abortion or stillbirth in Kars, Turkey. A total of 274 women were included -137 with a history of abortion or stillbirth, and 137 healthy controls. Participants completed a 26-item questionnaire assessing possible risk factors for infection. Serum samples were analysed using the micro-ELISA method. In the patient group, IgG and IgM seropositivity rates were 32.8% and 1.5%, respectively while in the control group, IgG and IgM were 35% and 0.7% respectively. Overall, the prevalences of IgG and IgM in the two groups were 33.9% and 1.1% respectively. The difference between the groups was not statistically significant (p > 0.05). Significant associations were found in the patient group between seropositivity and factors such as educational level, number of previous pregnancies, abortions, and preterm births, and the source of drinking water (p < 0.05). In the control group, income level, feeding cats in the garden, and consumption of raw milk were significantly associated with seropositivity (p < 0.05). However, no statistically significant association was found between T. gondii seropositivity and a history of abortion or stillbirth when compared with the control group. The findings also reveal a relatively high seroprevalence of T. gondii in the region and suggest that several sociodemographic and behavioral factors may contribute to exposure to the parasite. Therefore, public health interventions tailored to local hygiene and dietary habits are recommended.

Background Toxoplasma gondii is a protozoan parasite with worldwide distribution, infecting a broad-range of humans and warm-blooded animals. In the current study, role of this parasite on secondary sex ratio and risk of miscarriage was investigated. Methods In this cross-sectional study, 850 cord blood samples were collected in Tehran, Iran, 2014–2015. Enzyme-linked immunosorbent assay (ELISA) was used to assess anti- Toxoplasma IgG in samples. Information such as sex of the neonates and age, number of previous pregnancies and history of miscarriage of the mothers were recorded in questionnaires. Logistic regression analysis was used to assess the possible relationship between the latent toxoplasmosis and the highlighted parameters. Results Logistic regression analysis showed that the odds of having a male neonate in seropositive women is nearly 64% higher than that in seronegative women (OR = 1.64, CI 95  = 1.16–2.33, P  = 0.005). The odds ratio of having male neonate increased to 2.10 (CI 95  = 1.24–3.57, P  = 0.006) in high-titer seropositive women, compared to that in seronegative control group. The odds of having a miscarriage history was approximately two and a half times greater in seropositive women than in seronegative ones (OR = 2.45, CI 95  = 1.56–3.87, P  < 0.001). The odds ratio of having miscarriage increased to 2.76 (CI 95  = 1.61–4.73, P  < < .001) in low-titer seropositive women, compared to that in seronegative control group. Conclusion Results of the current study have shown that T. gondii infection affects secondary sex ratio in human offspring and can be addressed as one of the major miscarriage causes in women.

This study aimed to determine the prevalence of TORCH infections (Toxoplasma gondii, Rubella virus, Cytomegalovirus [CMV], and herpes simplex virus [HSV]) among pregnant women reported at Pakistan Institute of Medical Sciences (PIMS) Hospital in Pakistan. The study was conducted at PIMS from May 2021 to September 2022. This prospective study analyzed 8000 samples submitted to the pathology laboratory for routine testing. The ELISA method was employed to detect immunoglobulin M and immunoglobulin G antibodies. Statistical analysis was conducted using SPSS (version 23.0). TORCH agent infections during pregnancy account for 19.82% of cases. T. gondii is responsible for 5.1% of complete abortions, 6.6% of incomplete abortions, 4.8% of missed abortions, and 2.8% of threatened abortions. Rubella is another pathogen that can lead to abortion in pregnant women, contributing to 7.8% of complete abortions, 19.7% of incomplete abortions, 5.7% of missed abortions, and 5.5% of threatened abortions. CMV and HSV are also implicated in abortion. CMV accounts for 6.2% of complete abortions, 9.1% of incomplete abortions, 4.8% of missed abortions, and 5.2% of threatened abortions. HSV plays a significant role in abortion as well, causing 4.2% of complete abortions, 7.1% of incomplete abortions, 1.5% of missed abortions, and 4.0% of threatened abortions. Data with a p value of less than 0.001 indicate strong statistical significance. The findings suggest that TORCH agents and abortion are significantly correlated, with TORCH agent infections being a major cause of abortion. Women aged 15–44 had 50 abortions per 1000 in poor nations like Pakistan. Religion keeps abortion‐related issues like TORCH agent infection quiet in Pakistan. This is the first detailed report of TORCH infection in Pakistan. Toxoplasma gondii, Rubella, Cytomegalovirus, and herpes simplex virus cause 19.3%, 38.7%, 25.3%, and 16.8% of abortions. Pakistan has an alarming rate of abortions, and immediate action is needed.

BACKGROUND: Toxoplasmosis is a disease caused by Toxoplasma gondii and at least one-third of the world’s population has detectable T. gondii antibodies. The seroprevalence of T.gondii ranges from 15% to 50% among the Mexican general population. The aim of this work was to determine the mean prevalence and weighted mean prevalence of T. gondii infection, and to evaluate the epidemiological transition of infection in Mexico. METHODS: Pub Med, Lilacs, Medline, Latindex, Google Scholar data bases were searched to retrieve reports from 1951 up to 2012 regarding prevalence data, diagnostic tests and risk factors of infection among the adult population. Data collection and criteria eligibility was established in order to determine the crude prevalence (proportion of positive cases) of each study, together with weighted population prevalence according to individual research group categories to limit the bias that may impose the heterogeneous nature of the reports. A Forest Plot chart and linear regression analysis were performed by plotting the prevalence of infection reported from each study over a period of sixty years. RESULTS: A total of 132 studies were collected from 41 publications that included 70,123 individuals. The average mean prevalence was 27.97%, and weighted mean prevalence was 19.27%. Comparisons among different risk groups showed that the weighted prevalence was higher in women with miscarriages (36.03%), immunocompromised patients (28.54%), mentally-ill patients (38.52%) and other risk groups (35.13%). Toxoplasma infection among the Mexican population showed a downward trend of 0.1%/year over a period of sixty years that represents a 5.8% reduction in prevalence. CONCLUSIONS: This analysis showed a downward trend of infection; however, there are individuals at high risk for infection such as immunocompromised patients, mentally-ill patients and pregnant women. Further research is required to provide better prevention strategies, effective diagnostic testing and medical management of patients. Educational efforts are required to avoid the transmission of infection in populations that cannot be controlled by drugs alone.

The objective of this study was to estimate the seroprevalence of anti–Toxoplasma gondii antibodies and DNA of women with spontaneous abortions in 2 hospitals located in Yucatan, Mexico. Between June 2008 and May 2009, blood samples were taken from 100 women with spontaneous abortion attending the Ticul City Communitarian Hospital and the Merida Mother–Kid Hospital. The sera were tested for anti–T. gondii IgG and IgM antibodies. Blood samples (5 ml with anticlotting agent) were also used for polymerase chain reaction (PCR) assay, to detect T. gondii DNA. Forty-two of the 100 samples were negative. Of the positive samples (n = 58), 32 were positive to IgG, 2 to IgM, 5 to IgG and IgM, 6 to IgG and PCR, 1 to IgM and PCR, and 12 to IgG, IgM, and PCR. Accordingly, 55% of the women were seropositive to at least IgG, 20% to at least IgM, and 19% via PCR. Differences between hospitals were significant (P < 0.05) only for IgM. The risk of infection (IgM positive) was 2.85 (odds ratio [OR] 95%, confidence interval [CI]; 1.03–7.87) times greater in women patients at the Merida Mother–Kid Hospital, than those at the Ticul Communitarian Hospital. More studies are needed to evaluate the impact of this disease and to establish strategies to follow in order to reduce congenital toxoplasmosis in the populations at risk.

malaria during pregnancy is a major public health problem in Africa. It can have serious consequences for mother, fetus and newborn. It is associated with high maternal and infant mortality rate. The purpose of our study was to determine the prevalence of plasmodium infection in pregnant women, describe their clinical signs and potential complications, analyze associated factors, and propose preventive measures. we conducted a cross-sectional study at the Issaka Gazobi Maternity Ward (MIG), Niamey, from 1 June to 30 November 2017. Diagnosis was based on microscopic examination. two hundred and forty-nine (249) women were included in this study. The prevalence of plasmodium infection was 36.5% (IC95%; [30.6; 42.9]). Mean parasite density was 177 P/μl (SD: 121; [40; 800]). All infections were due to P. falciparum. Seventy-three point six percent (67/91) of infected women were asymptomatic. Only 26.4% (24/91) of them had uncomplicated malaria; 9.6% (6/91) had miscarriage; 38.4% of newborns were low birthweight; 26.51% (66/249) developed congenital malaria. Mortality rate was 1.1% (1/ 91). Intermittent preventive treatment (IPT) significantly protected patients against gestational malaria (p=0.01). in Niger, P. falciparum infection very commonly affects pregnant women. It is most often asymptomatic but it can lead to uncomplicated or even severe malaria. Main consequences include abortion, low birth weight, intrauterine growth retardation, congenital malaria and maternal death. IPT and the use of long-lasting insecticide-treated mosquito nets (LLINs) can prevent infection.

Malaria is endemic in India with an estimated 70-100 million cases each year (1.6-1.8 million reported by NVBDCP); of this 50-55% are Plasmodium vivax and 45-50% Plasmodium falciparum . A recent study on malaria in pregnancy reported from undivided Madhya Pradesh state (includes Chhattisgarh state), that an estimated over 220,000 pregnant women contract malaria infection each year. Malaria in pregnancy caused- abortions 34.5%; stillbirths 9%; and maternal deaths 0.45%. Bulk of this tragic outcome can be averted by following the Roll Back Malaria/WHO recommendations of the use of malaria prevention i.e. indoor residual spraying (IRS)/insecticide-treated bed nets (ITN) preferably long-lasting treated bed nets (LLIN); intermittent preventive therapy (IPT); early diagnosis, prompt and complete treatment using microscopic/malaria rapid diagnostics test (RDT) and case management. High incidence in pregnancy has arisen because of malaria surveillance lacking coverage, lack of age and sex wise data, staff shortages, and intermittent preventive treatment (IPT) applicable in high transmission states/pockets is not included in the national drug policy- an essential component of fighting malaria in pregnancy in African settings. Inadequate surveillance and gross under-reporting has been highlighted time and again for over three decades. As a result the huge problem of malaria in pregnancy reported occasionally by researchers has remained hidden. Malaria in pregnancy may quicken severity in patients with drug resistant parasites, anaemia, endemic poverty, and malnutrition. There is, therefore, urgent need to streamline malaria control strategies to make a difference in tackling this grim scenario in human health.

In the present study, it was aimed to detect seropositivity of T. gondii in sheep raised in the Silopi district. For this aim, blood samples were obtained from 100 female Hamdani sheep. The serum samples were examined using indirect fluorescent antibody (IFA) with respect of T. gondii specific antibody. Seropositivity was detected in 97 of sheep examined (97%). The seropositivity titers for the IFA test showed that 1:16 in 58 (59.7%), 1:64 in 22 (22.6%), 1:128 in 16 (16.4%) and 1:256 in 1 (%1) of sheep were found as seropositive. Seropositivity was observed as 96% in aborted sheep. Seropositivity was detected as 96% and 100% in 2-4 and 5-10 year old sheep, respectively. The relationship between age and seropositivity rate was not found significant (p > 0.05). The seropositivity of T. gondii was higher in sheep grown in Silopi.

Congenital toxoplasmosis can cause severe consequences in the fetus, such as spontaneous abortion which is affected by parasite strain. Also, recent studies revealed the high genetic diversity of Toxoplasma gondii . This study aims to investigate the serological status of T. gondii in pregnant women, multilocus genotyping in aborted fetuses’ tissue, and archived formalin‐fixed paraffin-embedded placenta. This study was performed on 100 pregnant women with spontaneous abortion and their aborted fetuses, and 250 of the archived placentae in Iran. The blood and tissue were examined for seroprevalence and genotype determination of T. gondii using ELISA and multilocus nested-PCR–RFLP, respectively. Anti- T. gondii IgG and IgM were detected in 68 samples (68%) and 1 (1%) out of 100 serums. Toxoplasma DNA was identified in 1 (1%) aborted fetuses’ tissue and 32 (12.8%) placenta samples. Overall, ten positive DNA samples were successfully genotyped, and five genotypes were recognized (ToxoDB#1, #2, #10, #27, and #48). The obtained results indicated congenital toxoplasmosis is a severe risk in this region. As type I is highly pathogen and can lead to severe complications, the prevention of the infection should be considered in seronegative pregnant women.
