13. Histopathology of murine toxoplasmosis under treatment with dialyzable leukocyte extract
BACKGROUND Dialyzable leukocyte extracts (DLEs) contain molecules smaller than 10 kDa with biological activity in receptor organisms. Primarily, they participate in the regulation of the Th1 immune response, which is essential for the control of several intracellular infections, such as toxoplasmosis. This disease is associated with congenital infection, en

14. Toxoplasma gondii seropositivity and risk factors in pregnant women followed up by the Family Health Strategy
INTRODUCTION : Toxoplasmosis is a zoonotic infection caused by Toxoplasma gondii. It is transmitted by the ingestion of contaminated water and foods, by soil contaminated with cat feces, especially while handling it, and congenitally via the placenta. The diagnosis of maternal infection is made by serological detection of either IgM or IgG antibodies. This

15. An atypical Toxoplasma gondii genotype in a rural Brazilian dog co-infected with Leishmania (Viannia) braziliensis
Toxoplasmosis and leishmaniasis are two worldwide zoonoses caused by the protozoan parasites Toxoplasma gondii and Leishmania spp., respectively. This report describes the clinical and laboratorial findings of a co-infection with both parasites in a 4-year-old female dog suspected of ehrlichiosis that presented anemia, thrombocytopenia, hypoalbuminemia, hype

16. Incidence of congenital toxoplasmosis among infants born to HIV-coinfected mothers: case series and literature review
Introduction:There is a paucity of data on the occurrence of congenital toxoplasmosis in children born to mothers dually infected with HIV and Toxoplasma gondii.Objective:To evaluate aspects of the mother–infant pairs associated with vertical transmission of toxoplasmosis in women co-infected with HIV in a referral center for perinatally acquired infection

17. Congenital toxoplasmosis in a reference center of Paraná, Southern Brazil
This study describes the characteristics of 31 children with congenital toxoplasmosis children admitted to the University Hospital of Londrina, Southern Brazil, from 2000 to 2010. In total, 23 (85.2%) of the mothers received prenatal care but only four (13.0%) were treated for toxoplasmosis. Birth weight was <2500 g in 37.9% of the infants. During the first

18. Toxoplasmosis: an examination of knowledge among health professionals and pregnant women in a municipality of the State of Paraná
Introduction The aim of this study was to investigate the knowledge of toxoplasmosis among professionals and pregnant women in the public health services in Paraná, Brazil. Methods A cross-sectional observational and transversal study of 80 health professionals (44 nurses and 36 physicians) and 330 pregnant women [111 immunoglobulin M (IgM)- and IgG-non-

19. Single nucleotide polymorphisms in the interferon gamma gene are associated with distinct types of retinochoroidal scar lesions presumably caused by Toxoplasma gondii infection
The association of single nucleotide polymorphisms (SNPs) in the interferon (IFN)-γ gene ( IFNG ) with different types of retinal scar lesions presumably caused by toxoplasmosis were investigated in a cross-sectional population-based genetic study. Ten SNPs were investigated and after Bonferroni correction, only the associations between SNPs rs2069718 and r

20. The performance of four molecular methods for the laboratory diagnosis of congenital toxoplasmosis in amniotic fluid samples
Introduction Toxoplasmosis may be life-threatening in fetuses and in immune-deficient patients. Conventional laboratory diagnosis of toxoplasmosis is based on the presence of IgM and IgG anti-Toxoplasma gondii antibodies; however, molecular techniques have emerged as alternative tools due to their increased sensitivity. The aim of this study was to compare

21. Toxoplasma gondii: prevalência de infecção, diagnóstico laboratorial e genótipos. / Toxoplasma gondii: prevalence of infection, laboratory diagnosis and genotype.
T. gondii é um parasito intracelular obrigatório e cosmopolita, cuja infecção de natureza congênita ou adquirida, resulta nas diferentes formas de toxoplasmose. A manifestação clínica desta doença é inespecífica e variável. Seu diagnóstico, essencialmente laboratorial, é direcionado a gestantes, neonatos, portadores de imunodeficiências, porta

22. Early diagnosis of congenital toxoplasmosis in newborn infants using IgG subclasses against two Toxoplasma gondii recombinant proteins
The aim of this work was to evaluate the utility of ELISA-based testing of total IgG (IgGt) antibodies and its subclasses (IgG1, IgG2, IgG3 and IgG4) against soluble (STAg) and recombinant (rSAG1 and rMIC3) antigens of Toxoplasma gondii for diagnosing congenital toxoplasmosis. Sera from 217 newborns initially testing positive for specific IgM in filter paper

23. Toxoplasma gondii antibody profile in HIV-1-infected and uninfected pregnant women and the impact on congenital toxoplasmosis diagnosis in Rio de Janeiro, Brazil
OBJECTIVE: Compare the anti-T. gondii IgG titer between HIV-1 infected and non HIV-1 infected pregnant women and report three cases of congenital toxoplasmosis resulting from reactivation of infection during pregnancy of HIV-1 infected women. METHODS: This study was conducted among 2,270 pregnant women with chronic Toxoplasma gondii infection (absence of IgM

24. Caracterização molecular de isolados de Toxoplasma gondii obtidos de crianças com toxoplasmose congênita no Estado de Minas Gerais
Toxoplasma gondii is a widely distributed Apicomplexa parasite with great medical importance. Congenital toxoplasmosis has been associated with abortion and stillborn, debility and neonatal mortality. Toxoplasmosis can be diagnosed through serologic methods or by directed methods: parasite isolation in mice (bioassay) or Polimerase Chain Reaction assay (PCR)
