Abstract
Introduction: Toxoplasmosis, a zoonosis caused by the parasite Toxoplasma gondii, is a significant global public health concern. Riverside communities often face unfavorable socioeconomic conditions that can lead to increased exposure to pathogens. This study aimed to investigate the frequency of antibodies against Toxoplasma gondii in two riverside communities in Northeastern Brazil.
Methodology: A cross-sectional, descriptive study was conducted between April/2022 and August/2024, involving the populations of the cities of Cabaceiras do Paraguaçu and Cachoeira in the Recôncavo Baiano region, Northeastern Brazil. Sociodemographic data were collected, and serological tests were performed to evaluate anti-T. gondii IgM and IgG.
Results: A total of 237 individuals were tested serologically for toxoplasmosis. The majority were female, self-identified as Black, with family incomes below the minimum Brazilian wage. In Cabaceiras do Paraguaçu, 40/74 (54.1%) individuals presented reactive anti-T. gondii IgG, while one (1.4%) was reactive for IgM. In Cachoeira, 80/163 (49.1%) were reactive for anti-T. gondii IgG, while 6 (3.7%) presented seropositivity for IgM. Individuals aged 31 years or older (Cabaceiras do Paraguaçu) and 15 years or older (Cachoeira) were associated with a higher chance of presenting anti-T. gondii IgG.
Conclusions: This study contributes to our understanding of the prevalence of toxoplasmosis and associated risk factors in riverside communities. The seroprevalence rates of toxoplasmosis identified in this study, including IgM-positive cases, reinforce the urgent need for interventions to prevent toxoplasmosis in riverside populations.
简介：弓形虫病是一种由弓形虫寄生虫引起的人畜共患病，是一个重大的全球公共卫生问题。河畔社区往往面临不利的社会经济条件，这可能导致接触病原体的机会增加。本研究旨在调查巴西东北部两个河畔社区弓形虫抗体的频率。方法：在2022年4月至2024年8月期间进行了一项横断面描述性研究，涉及巴西东北部Recôncavo Baiano地区Cabaceiras do paraguau和Cachoeira两市的人口。收集社会人口学数据，并进行血清学检测以评估抗t抗体。弓形虫IgM和IgG结果：共237人进行了弓形虫病血清学检测。大多数是女性，自认为是黑人，家庭收入低于巴西的最低工资。其中40/74（54.1%）出现t反应性。1例（1.4%）对IgM有反应。在Cachoeira中，80/163（49.1%）抗t反应。IgM血清阳性6例（3.7%）。年龄在31岁或以上的人（Cabaceiras do paragua）和15岁或以上的人（Cachoeira）出现抗t抗体的几率更高。刚免疫球蛋白。结论：本研究有助于了解河滨社区弓形虫病流行情况及相关危险因素。本研究确定的弓形虫病血清患病率，包括igm阳性病例，加强了采取干预措施预防河滨人群弓形虫病的迫切需要。
