“…The seroprevalence was lower than the ones reported in other countries such as: Senegal (40.3%) 11 , Turkey (39.6%) 14 , Bangladesh (38.5%) 1 , Croatia (38.1%) 27 and, Yugoslavia (57-93%) 7 , higher than the one observed in India (7.72%) 25 , and similar to the one reported in Mexico (33.4%) 34 .…”

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.

“…However, there was no difference when considering the student's school origin, they exhibited a very similar distribution in urban or rural zones. The majority of antibody titers were less than 1,024 (64.7% in urban zone and 67.7% in rural), a fact that may characterize previous infections by T. gondii, as suggested by Velasco Castrejón et al 22 . Such similarities suggest common risk and infection sources throughout the city.…”

“…The absence of a correlation between enteroparasites and toxoplasmosis in rural areas may be explained and children live in common space 22 , the neighborhood inhabited by them is large, which would contribute to reduce the risk of acquiring T. gondii via food contamination due to exposure from their surroundings.…”
