Selective anthelmintic treatment, advocated due to evolving anthelmintic resistance, has been associated with an increase in Strongylus vulgaris prevalence. Reverting to routine interval anthelmintic treatments is not viable and therefore, identifying other management factors correlated with S. vulgaris infection is vital.
To investigate possible risk factors associated with the presence of S. vulgaris infection in resident horses on Swedish horse establishments.
Internet-based questionnaire survey.
A questionnaire, created using the internet-based survey platform Netigate, was distributed to owners of equine establishments throughout Sweden via established equine platforms and social media channels. The survey was available for response from 21 May until 1 September 2022. Questions were closed ended with branching logic paths.
Four factors were significantly associated with S. vulgaris infection, with an increased odds of infection seen in livery yards (odds ratio [OR] 1.67, 95% confidence interval [CI] 1.18-2.36, p = 0.004) and premises with more than 10 resident horses (OR 2.42, 95% CI 1.64-3.56, p < 0.001). A lower odds of infection were seen in establishments using quarantine routines (OR 0.69, 95% CI 0.50-0.96, p = 0.03) and anthelmintic treatment of new horses prior to arrival at the premise (OR 0.37, 95% CI 0.18-0.74, p = 0.005).
Due to the presence of S. vulgaris infection in the present study being based on S. vulgaris diagnostics performed at the farm level, any association between faecal diagnostic use and risk of infection could not be investigated.
Although the use of diagnostics for S. vulgaris can keep infection rates low, large farms or livery yards with many different horse owners, and those with low use of biosecurity measures as regards to new horses arriving at the premise, are associated with a higher risk of infection.
由于抗蠕虫药耐药性的不断演变，提倡进行选择性驱虫治疗，但这与普通圆线虫感染率的上升有关。恢复常规间隔驱虫治疗并不可行，因此，确定与普通圆线虫感染相关的其他管理因素至关重要。
调查瑞典马场中常住马匹感染普通圆线虫的可能风险因素。
基于互联网的问卷调查。
使用基于互联网的调查平台Netigate创建的问卷，通过既定的马匹平台和社交媒体渠道分发给瑞典各地马场的业主。该调查于2022年5月21日至9月1日开放供回复。问题为封闭式，带有分支逻辑路径。
有四个因素与普通圆线虫感染显著相关，在寄养马场中感染几率增加（优势比[OR]为1.67，95%置信区间[CI]为1.18 - 2.36，p = 0.004），以及在有超过10匹常住马匹的场所（OR为2.42，95% CI为1.64 - 3.56，p < 0.001）。在采用检疫程序的场所感染几率较低（OR为0.69，95% CI为0.50 - 0.96，p = 0.03），以及在新马抵达场所之前对其进行驱虫治疗（OR为0.37，95% CI为0.18 - 0.74，p = 0.005）。
由于本研究中普通圆线虫感染的存在是基于农场层面进行的普通圆线虫诊断，因此无法调查粪便诊断的使用与感染风险之间的任何关联。
尽管使用普通圆线虫诊断可以使感染率保持在较低水平，但大型农场或有许多不同马主的寄养马场，以及对新马抵达场所的生物安全措施使用较少的马场，感染风险较高。
