Abstract
Objectives: This retrospective study aimed to evaluate the risk factors (age and breed group) associated with Angiostrongylus vasorum and Crenosoma vulpis infection in dogs.
Materials and methods: Faecal examinations obtained in dogs from January 2016 to December 2021 as part of routine clinical practice at two veterinary clinics in the Odsherred region of Zealand, Denmark, were included in this study. Faecal samples were analysed using the Baermann technique for nematode detection. Samples were collected from two clinics located in Northwestern Zealand, Denmark. Multinomial regression analysis, quasi-Poisson models and a generalised additive model for linearity were used to analyse the data.
Results: A total of 2,013 faecal samples were included in the study. Age was a significant risk factor for a positive Baermann, with a negative linear relationship observed (A. vasorum odds ratio: 0.80, 95% confidence interval: 0.70 to 0.91, C. vulpis odds ratio: 0.95, 95% confidence interval: 0.91 to 0.99, both nematodes: odds ratio: 0.87, 95% confidence interval: 0.77 to 0.99). Breed group analysis considering retrievers and flushing and water dog as reference group, demonstrated that sheep- and cattle dogs had a reduced risk of C. vulpis infection (odds ratio: 0.49, 95% confidence interval: 0.24 to 0.97), whereas dachshunds had an increased risk of A. vasorum infection (odds ratio: 3.28, 95% confidence interval: 1.14 to 9.47). Variations in the number of nematodes was found, with companion and toy dogs exhibiting higher numbers of C. vulpis (incidence rate ratio: 21.40, 95% confidence interval: 2.88 to 159) and sheep- and cattle dogs displaying higher numbers of A. vasorum (incidence rate ratio: 30.20, 95% confidence interval: 7.33 to 125). The prevalence rates of C. vulpis and A. vasorum were estimated at 14.50% (95% confidence interval: 13 to 16.10) and 3.40% (95% confidence interval: 2.70 to 4.30), respectively.
Clinical significance: There are significant risk factors for nematode infection in dogs that can be considered for proper preventive care of this condition.
期刊介绍：
Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery.
In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world.
The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher.
The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
