Twelve goats about 3 months of age were divided into 4 equal groups. Goats in Groups 1 and 2 were infected with orf virus followed by Corynebacterium pyogenes infection of Groups 1 and 3, 3 days after the first appearance of orf lesions. Goats in Group 4 were uninfected controls. Complicated orf lesions which consisted of wet suppurative scabs around the entire lips were observed in goats in Group 1. The lesions persisted for 24 days but were most severe from days 8 to 13. Goats in Group 2 developed lesions typical of orf virus infection that lasted 10 days, while goats in Group 3 developed small nodules of about 1 cm diameter, 48 hours following the introduction of C. pyogenes, which persisted for only 6 days. No lesion was observed in goats in Group 4. Two goats in Group 1 with complicated orf died after 16 and 22 days respectively.
12只约3月龄的山羊被分成4组，每组数量相等。第1组和第2组的山羊先感染口疮病毒，在口疮病变首次出现3天后，第1组和第3组再感染化脓棒状杆菌。第4组的山羊作为未感染的对照组。在第1组山羊中观察到复杂的口疮病变，整个嘴唇周围出现湿润的化脓性结痂。病变持续了24天，但在第8至13天最为严重。第2组山羊出现了典型的口疮病毒感染病变，持续了10天，而第3组山羊在引入化脓棒状杆菌48小时后出现了直径约1厘米的小结节，仅持续了6天。第4组山羊未观察到病变。第1组中有两只患有复杂口疮的山羊分别在第16天和第22天后死亡。
