One worm recovered from the orbit of a patient in Indiana, and two from the peritoneal cavity of another patient in California are described and classified as Dirofilaria. Both patients were elderly men who have lived all their lives in the United States. The main morphologic feature of these three immature worms is the presence of a smooth cuticle devoid of longitudinal ridges, similar to the cuticle of D. immitis. However, because other dirofilariid with similar cuticular characteristics have been found in animals in the Western Hemisphere, and they cannot be conclusively ruled out as the cause of the infection in our patients, a diagnosis of D. immitis-like organism is proposed for these nematodes. The relationship of these worms to other dirofilariid of animals and humans on the American continent is important because of the diagnostic problems these infections posed to practicing pathologists.
描述了从印第安纳州一名患者眼眶中取出的一条线虫以及从加利福尼亚州另一名患者腹腔中取出的两条线虫，并将它们归类为恶丝虫属。两名患者均为老年男性，一生都生活在美国。这三条未成熟线虫的主要形态特征是具有光滑的角质层，没有纵向脊，类似于犬恶丝虫的角质层。然而，由于在西半球的动物中发现了其他具有类似角质层特征的恶丝虫科线虫，并且不能确凿地排除它们是我们患者感染原因的可能性，因此建议将这些线虫诊断为类犬恶丝虫生物。由于这些感染给执业病理学家带来了诊断问题，所以这些线虫与美洲大陆动物和人类的其他恶丝虫科线虫的关系很重要。
