Mother-to-child transmission in Toxoplasma gondii infection occurs only when the infection is acquired for the first time during pregnancy. Diagnosis of maternal infection and the newborn is achieved by a combination of serological tests, clinical features and ultrasound images. An early diagnosis of maternal infection allows treatment that offers a reduction both in transmission rate and risk of congenital damage.

[Prevalence of anti-Toxoplasma gondii antibodies in pregnant women in seven hospitals in Buenos Aires area. Comparison 2006 vs. 2017].

We analyzed the presence of IgG and IgM anti-Toxoplasma gondii, as a measure of infection, in pregnant women attending seven hospitals in the Metropolitan Area of Buenos Aires during 2006 and 2017. T. gondii seroprevalence in 2006 vs.

HTLV-1 cosmopolitan and HTLV-2 subtype b among pregnant women of non-endemic areas of Argentina.

Objectives: The objective of this study was to estimate the prevalence of human T cell lymphotropic virus (HTLV)-1/2, HIV-1, hepatitis B virus (HBV), Trypanosoma cruzi, Treponema pallidum and Toxoplasma gondii infections and to identify the subtypes/subgroups of HTLV-1/2 among pregnant women (PW) from non-endemic provinces of Argentina.

Methods: Methods A total of 2403 samples were screened for HTLV-1/2 and confirmed by western blot and PCR. The long terminal repeat (LTR) of HTLV-1 and HTLV-2 were amplified.

[Multicenter study on the prevention of congenital toxoplasmosis in Buenos Aires].

Toxoplasmosis is an infection caused by Toxoplasma gondii, an intracellular parasite of universal distribution, with a variable prevalence depending on the region. This infection causes both morbidity and mortality in the fetus and newborn. The present study is an evaluation of the Argentine Consensus Guidelines regarding prenatal prevention of toxoplasmosis.

[Argentine Consensus of Congenital Toxoplasmosis].

The mother-to-child transmission in Toxoplasma gondii infection occurs only when the infection is acquired for the first time during pregnancy. The prenatal and early postnatal diagnosis can only be achieved by serological testing. Serologic tests have different sensitivities, specificities and complexities, so that different tests in more than one blood sample are necessary for the diagnosis.
