Toxoplasmosis and neosporosis are parasitic diseases of global importance. The present study had the objective to determine the influence of age, sex and breed in the prevalence of antibodies against both diseases in dogs from Brotas city, São Paulo State, Brazil. Blood samples of 342 dogs were collected, and the age, sex and breed of each animal were recorded. The serological diagnosis for toxoplasmosis and neosporosis were performed using the immunofluorescent antibody test (IFAT). The Fischer's test was used to calculate the association probability of the variables, with α = 5%. For toxoplasmosis the prevalence of antibodies was 26.9% (CI 95% 22.4-31.8%), and for neosporosis 4.97% (CI 95% 3.1-7.8%). The statistical analysis revealed a higher risk of infection for T. gondii in dogs with more than five years.
弓形虫病和新孢子虫病是具有全球重要性的寄生虫病。本研究旨在确定年龄、性别和品种对巴西圣保罗州布罗塔斯市犬类这两种疾病抗体流行率的影响。采集了342只犬的血液样本，并记录了每只动物的年龄、性别和品种。使用免疫荧光抗体试验（IFAT）对弓形虫病和新孢子虫病进行血清学诊断。采用费舍尔检验计算变量的关联概率，α = 5%。弓形虫病抗体流行率为26.9%（95%置信区间22.4 - 31.8%），新孢子虫病为4.97%（95%置信区间3.1 - 7.8%）。统计分析显示，年龄超过五岁的犬感染刚地弓形虫的风险更高。
