Lame pigs, up to 12 weeks of age, were necropsied to establish a diagnosis. Of 175 pigs examined, 165 were confirmed to have arthritis by histopathological examination of joint tissues. Lesions were most common in the elbow and tarsal joints and least common in the joints of the feet. Typically, there was severe fibrinopurulent inflammation of synovial membranes regardless of the bacteria isolated. A bacterial aetiology was found in 114 (69%) of the 165 pigs. In arthritic pigs in which an aetiology was established the causative agents were Staphylococcus hyicus ssp hyicus (24.6%), Streptococcus equisimilis (26.3%), Actinomyces pyogenes (13.2%), Staphylococcus aureus (7.9%) and Haemophilus parasuis (7.9%). While gender did not affect the prevalence of arthritis, there was an age influence, most of the pigs culled for arthritis being under 6 weeks of age.
对12周龄及以下的跛脚猪进行尸检以确诊。在检查的175头猪中，通过关节组织的组织病理学检查证实有165头患有关节炎。病变在肘关节和跗关节最为常见，在足部关节最少见。通常，无论分离出何种细菌，滑膜均有严重的纤维蛋白脓性炎症。在165头猪中有114头（69%）发现有细菌病因。在确定病因的关节炎猪中，致病因子为猪葡萄球菌猪葡萄球菌亚种（24.6%）、类马链球菌（26.3%）、化脓放线菌（13.2%）、金黄色葡萄球菌（7.9%）和副猪嗜血杆菌（7.9%）。虽然性别不影响关节炎的患病率，但存在年龄影响，大多数因关节炎被淘汰的猪在6周龄以下。
