Two prominent physicians, Grancher and Brouardel, were sent by the French Health authorities to study the severe ongoing outbreak of trichinellosis in Emersleben, Germany (1883). They produced a highly accurate description of the outbreak and confirmed that they had never observed such cases in France. Grancher performed two necropsies and very precisely described the histological lesions provoked by the larvae entering and transforming muscular fibers. They also had the opportunity to meet Virchow in Berlin and they emphasized his extreme kindness. This French medical mission and cooperation with famous German scientists such as Virchow is probably one of the first examples of international collaboration on trichinellosis. It prefigured the international collaborative efforts made by the International Commission on Trichinellosis which was created in 1958 and is still active.

法国卫生当局派遣了两位著名的医生 Grancher 和 Brouardel，研究德国埃默斯莱本（1883 年）持续爆发的旋毛虫病。他们对疫情进行了高度准确的描述，并确认他们从未在法国观察到此类病例。Grancher 进行了两次尸检，并非常准确地描述了幼虫进入并转化肌肉纤维所引起的组织学病变。他们还有机会在柏林会见了 Virchow，他们强调了他的极度友善。这次法国医疗任务以及与 Virchow 等德国著名科学家的合作可能是旋毛虫病国际合作的首批例子之一。
