Two cases of unsuspected Strongyloides stercoralis infection were elucidated by the displacement of bacterial colonies on primary plating media. Observation of primary plates inoculated for the diagnosis of bacterial pneumonia or gastroenteritis revealed that normal flora colonies had been moved and were aligned in a pathway, or track. This unusual colony alignment prompted us to request a stool for the examination of parasites, and S. stercoralis was found. It was concluded that the parasite is capable of motility on agar surfaces, resulting in the displacement of bacterial colonies that make up the normal flora.
两例未被怀疑的粪类圆线虫感染通过初代平板培养基上细菌菌落的移位得以阐明。在接种用于诊断细菌性肺炎或肠胃炎的初代平板时观察到，正常菌群菌落发生了移动，并排列成一条路径或轨迹。这种不寻常的菌落排列促使我们要求送检粪便以检查寄生虫，结果发现了粪类圆线虫。得出的结论是，该寄生虫能够在琼脂表面移动，导致构成正常菌群的细菌菌落移位。
