“…53 No Brasil, a prevalência de infecção por T. gondii em humanos é especialmente alta e pode chegar a 100% em algumas áreas e em média 60% das mulheres adultas já foram expostas a este protozoário. [54][55][56] Felídeos geralmente são considerados fontes primárias de infecção e hospedeiros definitivos, adquirindo o protozoário através da ingestão de carne ou fezes contaminadas. Inúmeros hospedeiros intermediários podem disseminar a doença, ou o parasito entre eles, consumindo a carne de outros indivíduos infectados.…”

“…However, both studies did not test for IgM antibodies. In Brazil, the prevalence of Toxplasma IgG was 16% among pregnant women while that of IgM was 1% in the same population (de Quadros et al, 2015). Moreover, in an Ethiopian study, the seroprevalence was found to be 60% and 64% in females and males respectively (Negash et al, 2008).…”

Background: Toxoplasma gondii is a zoonotic parasite that has arisen as an important opportunistic infection that causes morbidity and mortality especially in HIV positive patients. This study was carried out to determine the sero-prevalence of T. gondii (IgG and IgM) and the associated risk factors among HIV positive and negative patients in Northern South Africa. Materials and Methods:The study was conducted in the Vhembe District in Limpopo province from April 2012 to January 2013. A well-structured questionnaire was used to collect socio-demographic information and possible risk factor information on toxoplasmosis from participants. A total of 161 blood samples of both HIV positive and negative patients visiting the local clinics in the Vhembe district were collected. Serum samples were tested for IgG and IgM against T. gondii using commercially available ELISA protocol. Results: The prevalence of T. gondii IgG was 31.7% while that of T. gondii IgM was 4.9%. The prevalence of T. gondii IgG was higher in HIV positive patients (38%) compared to 16.7% among HIV negative patients (p=0.001). Toxoplasma gondii IgG antibodies were more common in patients who were not taking ARV's (46.2%) compared to those who were taking ARV's (35.2%) (P<0.001). Conclusions:The present study has shown a high prevalence of T. gondii (IgG) among patients attending different HIV clinics in the Vhembe district with no current infections among pregnant women. In addition to the sero-positive status of the patient to HIV, other significant risk factors for toxoplasmosis included high viral load, non-adherence to ARV therapy and age (>25 years).

“…Infection by this parasite in humans may occur through water and foods contaminated by oocysts, or it may be congenital, when the pregnant woman becomes contaminated during pregnancy and the etiologic agent crosses the placental barrier. 1,2 It is estimated that 1/3 of the world population is infected, but prevalence varies in different regions. In Brazil, seroprevalence varies between 42% and 90% of the population.…”

“…The incidence of fetal infection is higher when the disease is acquired in the third trimester compared with the first trimester, but the severity of the involvement is greater when maternal infection occurs in the first trimester. 1,3,[9][10][11][12] In pregnant women with exams that suggest acute infection, it is necessary to determine whether there is any impairment to the fetus. In these situations, one can perform amniocentesis to detect the presence of the parasite's DNA in the amniotic fluid through the polymerase chain reaction (PCR) method.…”

Objective To describe a population of pregnant women diagnosed with toxoplasmosis and their respective newborns, describing the hospital protocol for treatment and follow-up. Methods Retrospective cohort of pregnant women with acute toxoplasmosis infection and risk of transplacental transmission who were sent to the Fetal Medicine Group of Hospital de Clínicas de Porto Alegre (HCPA) between -January 1, 2006 and December 31, 2016. All patients with confirmed disease were included. The diagnostic protocol and treatment were applied; a polymerase chain reaction (PCR) analysis of the amniotic fluid was used to diagnose toxoplasmosis and determine the treatment. The newborns were followed up at the pediatric outpatient clinic specializing in congenital infection. The patients who were not followed up or were not born in the HCPA were excluded. Results A total of 65 patients were confirmed to have gestational toxoplasmosis; 40 performed amniocentesis, and 6 (15%) were identified as having positive PCR in the amniotic fluid. In five of those cases, this result associated with the gestational age defined the triple therapy during pregnancy, and in one case, it defined the monotherapy (advanced gestational age). A total of 4 of these newborns were treated from birth with triple therapy for 10 months, 1 was not treated (due to maternal refusal), and 1 progressed to death within the first 54 hours of life due to complications of congenital toxoplasmosis. Of the 34 remaining cases with a negative PCR, 33 were treated with monotherapy and 1 was treated with triple therapy (ultrasound findings); of these children, 9 (26.5%) presented negative immunoglobulin G (IgG), 24 (70.6%) presented Ana Lúcia Letti Müller's ORCID is https://orcid.org/0000-0003-1214-5664.
