Description
Summary:Pernambuco has 195 quilombos, yet little is known about the epidemiology of human toxoplasmosis in these communities. This study aimed to determine the seroprevalence of Toxoplasma gondii in quilombola humans. Blood samples were collected from 82 individuals (28 men and 54 women) from eight quilombola communities located in the Pajeú and Mata Meridional Pernambucana microregions, Brazil. The samples were subjected to the Indirect Fluorescent Antibody Test (IFAT) to detect anti-Toxoplasma gondii IgG and IgM antibodies, using cutoff point of 1:16. To elaborate the geographic distribution of the seroprevalence, the communities’ coordinates were obtained using GPS equipment. A seroprevalence of 54.9% (45/82) was observed among quilombolas in Pernambuco state. Notable, 62.5% (51/82) of the communities had quilombolas testing reagent for anti-T. gondii IgM. Studying the seroprevalence of T. gondii infection in quilombolas provides essential insights into the epidemiology of toxoplasmosis in these communities. The findings can be used for planning disease control strategies, the development of health services and technical assistance and rural extension services. Additionally, they support the creation of public health policies aimed at improving water access and implementing social technologies tailored to each community.
