Magellanic penguins (Spheniscus magellanicus) breed on the Atlantic and Pacific coasts of the southernmost parts of South America and migrate northward as far as Peru and Brazil. Serum samples (n = 100) from Magellanic penguins from three zoos and two rehabilitation centers (RCs) in Brazil were assayed for the presence of antibodies to Toxoplasma gondii by means of the modified agglutination test (MAT, cut-off ≥ 20). The penguins were categorized as young (≤4 yr old) or adults (≥4 yr old) and sexed (male, female, or not identified), and data were analyzed using the chi-square test (P ≤ 0.05). Toxoplasma gondii antibodies were found in 28% of penguins: 25.8% males, 27.8% females, 30.3% unknown sex, 25.4% young, and 31.1% adults. Statistical analyses did not find any difference (P > 0.05) with respect to age, sex, or source of birds. This is the first report of T. gondii antibodies in S. magellanicus.
麦哲伦企鹅（Spheniscus magellanicus）在南美洲最南端的大西洋和太平洋沿岸繁殖，并向北迁徙至秘鲁和巴西。采用改良凝集试验（MAT，截断值≥20）对来自巴西三个动物园和两个康复中心（RCs）的麦哲伦企鹅血清样本（n = 100）进行检测，以确定是否存在抗刚地弓形虫抗体。企鹅被分为幼年（≤4岁）或成年（≥4岁），并确定性别（雄性、雌性或未识别），数据采用卡方检验进行分析（P≤0.05）。在28%的企鹅中发现了刚地弓形虫抗体：雄性为25.8%，雌性为27.8%，性别未知的为30.3%，幼年为25.4%，成年为31.1%。统计分析未发现鸟类的年龄、性别或来源存在任何差异（P>0.05）。这是麦哲伦企鹅中存在刚地弓形虫抗体的首次报告。
