We assessed the bacterial agents found in 8-12-wk-old post-weaning pigs with arthritis. The bodies of 178 post-weaning pigs from 90 farms (average of 2 pigs/farm) with recurrent problems of lameness and swollen joints in a high-density breeding area were submitted for autopsy and sampled for further bacterial investigation. The most common articular gross lesions and histopathologic findings were serofibrinous (95 of 178; 53%) or serous (65 of 178; 37%) arthritis; suppurative lesions were less frequent (18 of 178; 10%). In 133 of 178 (74.7%) cases, a bacterial agent was detected in joints. was the most common bacterium detected (82 of 133; 61.6%). and spp. were observed in 27 of 133 (20.3%) and 24 of 133 (18.0%) cases, respectively. Other bacteria in the 113 cases, considered less important, in order of their low frequency, were spp. (13; 9.8%), (11; 8.2%), (4; 3.0%), spp. (3; 2.2%), (2; 1.5%), and spp. (2; 1.5%). Our results highlight the primary role of compared to other microorganisms involved in young pigs with arthritis.
我们评估了 8-12 周龄断奶后出现关节炎的猪体内发现的细菌病原体。从高密度养殖区 90 个农场的 178 头经常出现跛行和关节肿胀问题的断奶后猪中采集了尸体样本并进行了进一步的细菌调查。最常见的关节大体病变和组织病理学发现是浆液纤维性（178 例中的 95 例，53%）或浆液性（178 例中的 65 例，37%）关节炎；化脓性病变较少见（178 例中的 18 例，10%）。在 178 例中的 133 例（74.7%）病例中，关节中检测到细菌病原体。是检测到的最常见细菌（133 例中的 82 例，61.6%）。和 spp.在 133 例中的 27 例（20.3%）和 24 例（18.0%）中分别观察到。在 113 例其他不太重要的病例中，按其低频率依次为 spp.（13 例，9.8%）、（11 例，8.2%）、（4 例，3.0%）、 spp.（3 例，2.2%）、（2 例，1.5%）和 spp.（2 例，1.5%）。我们的结果突出了 与其他参与幼猪关节炎的微生物相比的主要作用。
