BACKGROUND
Leishmania infantum and Toxoplasma gondii are protozoa with zoonotic and economic importance. Prevalences of antibodies to these agents were assessed in 173 horses from the north of Portugal.
FINDINGS
Antibodies to L. infantum were detected by the direct agglutination test (DAT); seven (4.0%) horses were seropositive with DAT titres of 200 (n = 5), 800 (n = 1) and ≥ 1600 (n = 1). Antibodies to T. gondii were assayed by the modified agglutination test (MAT); 23 (13.3%) horses were seropositive with MAT titres of 20 (n = 13), 40 (n = 5), 80 (n = 3) and ≥ 160 (n = 2). No statistical differences were found among equine categories of gender (female, male and gelding), age (1.5-6, 7-12 and 13-30 years), type of housing (indoors and mixed/outdoors), ability (recreation, farming and sports) and clinical status (apparently healthy and sick) for both agents.
CONCLUSIONS
Horses are exposed to and may be infected with L. infantum and T. gondii in the north of Portugal.
背景
利什曼原虫和刚地弓形虫是具有动物源性和经济重要性的原生动物。评估了葡萄牙北部 173 匹马对这些病原体的抗体流行率。
结果
通过直接凝集试验（DAT）检测到利什曼原虫抗体；7 匹（4.0%）马 DAT 滴度为 200（n=5）、800（n=1）和≥1600（n=1）呈血清阳性。通过改良凝集试验（MAT）检测到刚地弓形虫抗体；23 匹（13.3%）马 MAT 滴度为 20（n=13）、40（n=5）、80（n=3）和≥160（n=2）呈血清阳性。对于两种病原体，马的性别（母马、公马和去势马）、年龄（1.5-6、7-12 和 13-30 岁）、住房类型（室内和混合/室外）、能力（娱乐、农业和运动）和临床状况（明显健康和患病）等类别之间没有发现统计学差异。
结论
在葡萄牙北部，马接触并可能感染利什曼原虫和刚地弓形虫。
