Abstract
Seven different flotation fluids were assessed for their efficiency in recovering Toxocara canis ova from artificially seeded soil samples. Using the most efficient (a saturated solution of magnesium sulphate plus 5% potassium iodide) 25 g amounts of 234 environmental soil samples were examined for the presence of Toxocara spp. and Toxascaris ova. Twenty-six samples (11.1%) yielded ova of one or other species. There was no discernible pattern of distribution of positives with relation to the source of the samples. The maximum number of ova recovered in any one sample was 19. All the ova recovered from the environment were considered viable and potentially infective.
摘要
对七种不同的浮选液进行了评估，以确定它们从人工接种的土壤样本中回收犬弓首蛔虫卵的效率。使用效率最高的浮选液（硫酸镁饱和溶液加5%碘化钾），对234份25克重的环境土壤样本进行了检查，以确定是否存在弓首蛔虫属和弓蛔线虫卵。26个样本（11.1%）检出了一种或另一种虫卵。阳性样本的分布与样本来源没有明显的模式。任何一个样本中回收的虫卵最多为19个。从环境中回收的所有虫卵都被认为是有活力且可能具有感染性的。
