Two Saanen does on the same farm developed signs of polyarthritis. Streptococcus dysgalactiae was isolated on microbial culture of samples from multiple joints of both goats. Antibiotic susceptibility testing of the S dysgalactiae revealed resistance to tetracycline, a commonly used antibiotic to treat arthritis in goats. The isolate was susceptible to penicillin. Polyarthritis was clinically diagnosed in 25 Saanen goats on this farm over a 2-year period. Streptococcus dysgalactiae has been reported as a cause of polyarthritis in calves and lambs and should be considered as a cause of polyarthritis in adult goats. Joint fluid samples for Mycoplasma, aerobic bacterial, and Chlamydia culture and serum samples for caprine arthritis-encephalitis virus serologic testing should be obtained from live goats during clinical evaluation of herd outbreaks of polyarthritis.
同一农场的两只萨能奶山羊出现了多关节炎症状。从两只山羊多个关节的样本进行微生物培养时分离出了停乳链球菌。对停乳链球菌进行的药敏试验显示其对四环素耐药，四环素是治疗山羊关节炎常用的抗生素。该分离株对青霉素敏感。在两年时间里，该农场有25只萨能山羊被临床诊断为多关节炎。停乳链球菌已被报道可引起犊牛和羔羊的多关节炎，也应被视为成年山羊多关节炎的病因之一。在对畜群多关节炎疫情进行临床评估时，应从活山羊身上采集关节液样本进行支原体、需氧菌和衣原体培养，以及采集血清样本进行山羊关节炎脑炎病毒血清学检测。
