“…In spite of the aforesaid picks of prevalence, the high titer geometric mean (TGM) of 11-15 years old group and an inverse relationship between the age and TGM suggest that the women of the studied community were infected in the first decades of life, which is in agreement with previous studies 1,11,13,25 . The TGM of 16-35 years old group is very near to overall TGM (302.…”

SuMMarYThe aim of this study was to determine the prevalence of anti-T. gondii total and IgM antibodies in women of childbearing age. One hundred serum samples of women were studied with age range from 11 to 45 years old. Samples were chosen by random. The determination of total antibodies was carried out through the indirect hemagglutination technique and IgM antibodies by ELISA's technique. The statistical analysis was carried out through the Chi square and the Spearman correlation tests. The theoretical estimated incidence of congenital toxoplasmosis was calculated, according to the annual increment of antibody prevalence among the age groups. The overall prevalence of toxoplasmosis was 33%, while only six individuals (18.2%) were positive to IgM. The highest prevalence was observed in the 11-35 year-old age group. The theoretical estimated incidence was 1.5 for 100 pregnancies in women of 21-25 year-old group; it decreased until 0.1% in the 41-45 year-old age group. The findings show a high prevalence of toxoplasmosis in this community with a high infection risk in women of the studied age group and the high cat population observed, suggesting that the transmission way by contaminated soils may play a main role in the spreading of toxoplasmosis in this community.

“…The frequencies of seroreactivity for T. gondii among the inhabitants of the villages Utiariti and Bacaiuval/Morrim were higher than those seen in the study by Amendoeira et al (2003) (80.4%). On the other hand, the findings from the villages Seringal/Cabeceira do Seringal, Quatro Cachoeiras and Bacaval were similar to those of Díaz-Suárez et al (2003), who found seroreactivity of 62.7%; Bóia et al (2008), 73.5% and Devera et al (2013), 51.63%.…”

Toxoplasma gondii is the etiological agent of toxoplasmosis, a widespread zoonosis that affects several homeothermic animals, including humans. This disease causes serious health problems, such that 10% of infected individuals develop clinical manifestations. Some studies on indigenous human populations have indicated variations in seroprevalence from 10.6% to 80.4% in such populations in different regions of Brazil and in other countries like Venezuela and Malaysia. To date, there have been no studies regarding the prevalence of anti- T. gondii antibodies in Haliti-Paresí Indians living in Campo Novo do Parecis, Mato Grosso, Brazil. Our objective here was to determine the frequency of occurrence of antibodies against this protozoon in nine Haliti-Paresí villages by correlating seroprevalence with locations and variables. Serodiagnoses were made using the indirect immunofluorescence antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA) in the Laboratory for Toxoplasmosis and Other Protozoan Diseases of IOC/Fiocruz. It was considered that samples tested positive for T. gondii infection if IgG/IgM antibodies against this protozoon were detected through serodiagnosis using either IFAT or ELISA. Among the 293 samples analyzed, 66.9% presented anti- T. gondii IgG and 3.4% presented anti- T. gondii IgM. It was observed that there were no statistically significant differences in frequency of antibody occurrence among infected individuals, based on sex, schooling or occupation/activities. However, there were statistical differences based on age and villages. The prevalence observed in this study is in agreement with values found in other studies on indigenous populations in Latin America. Like among other such populations, the Haliti-Paresí villages are located close to forests and the individuals have domestic cats as pets, are involved in hunting and farming and consume water directly from water accumulation sources. These factors might cause exposure to T. gondii tissue cysts and oocysts.

“…En estudio realizado en la comunidad indígena de la etnia Yucpa, localizada en la Sierra de Perijá, Estado de Zulia, Venezuela, se detectó anticuerpos de la clase IgM, característica de la fase aguda, en ocho mujeres entre las 45 examinadas, lo que corresponde a 17,8% de positividad. Tal hecho indicó la posibilidad de la transmisión vertical vía transplacentaria en mujeres indígenas en edad fértil en la comunidad estudiada (20).…”

Objetivos: Determinar la frecuencia de toxoplasmosis aguda en mujeres embarazadas en la ciudad de Rio de Janeiro, Brasil. Material y métodos: Se incluyeron 2 673 mujeres embarazadas, asintomáticas para toxoplasmosis, durante el 2007. Se determinó IgM anti T. gondii en suero mediante inmunofluorescencia indirecta como diagnóstico de sensibilidad y la confirmación de los casos positivos por medio de ELISA. Se determinó el coeficiente de prevalencia. Resultados: Once (0,41%) tenían anticuerpos IgM anti-Toxoplasma gondii, con títulos iguales o mayores a 1:16. Conclusiones: La prevalencia de toxoplasmosis aguda en gestantes asintomáticas de la ciudad del Rio de Janeiro es baja, menor del promedio nacional de Brasil.
