Toxocara species ova were found in 16 of 146 (11 per cent) soil samples collected from backyards and gardens of private residences within Baltimore City. The recovery rate of parasite ova was similar for households regardless of their grouping by pet ownership characteristics or the presence of visible animal feces. The findings demonstrate the common occurrence of these eggs in locations likely to be important in the transmission of visceral larva migrans.
在从巴尔的摩市私人住宅的后院和花园采集的146份土壤样本中,有16份(11%)发现了弓蛔虫属虫卵。无论家庭根据宠物饲养特征分组情况或是否存在可见动物粪便,寄生虫卵的回收率都相似。这些发现表明,这些虫卵在可能对内脏幼虫移行症传播至关重要的地点普遍存在。
