Toxoplasma gondii is an important pathogen in aquatic mammals and its presence in these animals may indicate the water contamination of aquatic environment by oocysts. Serum samples from 95 free-living Amazon River dolphins (Inia geoffrensis) from the Mamirauá Sustainable Development Reserve (RDSM), Tefé, Amazonas, Central Amazon, Brazil were tested for T. gondii antibodies using the modified agglutination test (MAT). Antibodies (MAT ≥ 25) to T. gondii were found in 82 (86.3%) dolphins with titers of 1:25 in 24, 1:50 in 56, and 1:500 in 2. Results suggest a high level contamination of the aquatic environment of the home range of these animals.
刚地弓形虫是水生哺乳动物中的一种重要病原体，其存在于这些动物体内可能表明水生环境受到了卵囊的污染。使用改良凝集试验（MAT）检测了来自巴西亚马孙中部特菲市马米拉瓦可持续发展保护区的 95 头自由生活的亚马孙河豚（Inia geoffrensis）血清样本中的弓形体抗体。结果显示，82 头（86.3%）海豚的抗体效价≥25，其中 24 头为 1:25，56 头为 1:50，2 头为 1:500。结果表明，这些动物栖息地的水生环境受到了高度污染。
