FREQUENCY OF ANTI-TOXOPLASMA GONDII ANTIBODIES IN DOGS WITH CLINICAL SIGNS CONSISTENT WITH TOXOPLASMOSIS

Abstract: The aim of this study was to detect antibodies against T. gondii in dogs with clinical signs compatible with toxoplasmosis attended in a veterinary hospital. A serological survey was performed in 598 dogs from 1993 to 2013. The IgG antibodies survey against T. gondii was carried out by means of Indirect Fluorescence Antibodies Test (IFAT); samples with titers ≥16 were considered positive. Among the dogs with clinical signs, 259 (43,31%) were positive for T. gondii with titers varying between 16 to 4096; among the healthy animals, 79 (22.25%) were reagents. The most frequent signals were: neurological (30.43%) and uveitis (8.03%). Among variables race, gender, and age, only the last one affected the observed results with greater frequency f seropositive in elderly dogs.

摘要：本研究旨在对某兽医院接诊的、表现出与弓形虫病相符临床症状的犬只，开展抗刚地弓形虫（Toxoplasma gondii）抗体检测。本研究于1993年至2013年间，对598只犬只实施血清学调查。采用间接荧光抗体试验（Indirect Fluorescence Antibodies Test，IFAT）检测抗刚地弓形虫IgG抗体，以抗体滴度≥16作为阳性判定标准。在表现出临床症状的犬只中，259只（占比43.31%）抗刚地弓形虫抗体检测呈阳性，其抗体滴度介于16至4096之间；在健康犬只中，79只（占比22.25%）检测结果为阳性。本次调查中最常见的临床症状为神经系统症状（占比30.43%）与葡萄膜炎（占比8.03%）。在品种、性别与年龄这三个变量中，仅年龄对检测结果存在显著影响，老年犬的血清阳性率更高。
