Although it is generally accepted that spp. can induce fertility problems in sows, many questions concerning diagnostic, therapeutic, and prophylactic approaches remain unanswered. The aim of this study was to gather information about how swine practitioners deal with these knowledge gaps.
Austrian swine practitioners were anonymously asked for their assessment of chlamydiosis using the Lime Survey program.
PCR tests are used for molecular chlamydia detection from abortion material (64.3%), vaginal swabs (40.5%), and the genital tract (postmortem slaughterhouse samples) (9.5%). Treatment mainly includes tetracyclines (95.2%), occasionally macrolides (2.4%) or other (not mentioned) antibiotic groups (7.1%). Treatment periods vary greatly, from 5 to 10 days (23.8%), from 11 to 15 days (47.6%), from 16 to 21 days (11.9%), and >21 days (9.5%). Prophylactic measures include hygiene improvement, rodent control, and herd treatments with tetracyclines.
Serological methods are perceived as inadequate, and there is a general need for better guidance on interpreting results. Knowledge about the increased incidence of tetracycline-resistant strains is limited. Weighing up economic interests, feasibility, and animal welfare plays an important role. Further research to improve diagnosis and prevention of chlamydia-related fertility diseases in sows is urgently needed.
尽管人们普遍认为 spp. 可导致母猪繁殖问题，但关于诊断、治疗和预防方法的许多问题仍未得到解答。本研究的目的是收集有关猪兽医如何应对这些知识空白的信息。
通过 Lime Survey 程序匿名询问奥地利猪兽医对衣原体病的评估。
聚合酶链反应（PCR）检测用于从流产材料（64.3%）、阴道拭子（40.5%）和生殖道（屠宰场死后样本）（9.5%）中进行衣原体分子检测。治疗主要包括四环素（95.2%），偶尔使用大环内酯类药物（2.4%）或其他（未提及）抗生素组（7.1%）。治疗期差异很大，从 5 至 10 天（23.8%）、11 至 15 天（47.6%）、16 至 21 天（11.9%）到超过 21 天（9.5%）。预防措施包括改善卫生、控制鼠害以及用四环素对猪群进行治疗。
血清学方法被认为不足，并且普遍需要关于结果解读的更好指导。关于四环素耐药菌株发病率增加的知识有限。权衡经济利益、可行性和动物福利起着重要作用。迫切需要进一步研究以改善母猪衣原体相关繁殖疾病的诊断和预防。
