This study was performed in order to gather recent epidemiological data on feline endoparasites in Swedish cats. Faecal samples from 205 outdoor cats were collected by their owners and submitted to the National Veterinary Institute for analysis. The study population was comprised of cats with access to an outdoor environment and with no history of anthelmintic treatment within the last 3 months. Intestinal parasites were detected with a centrifugal flotation technique and Baermann larval sedimentation was performed to detect metastrongylid lungworms. Eggs, larvae and oocysts were identified morphologically by microscopic examination. The following information was collected from cat owners: breed, sex, age, anthelminthic medication last used, observation of cestode proglottids and residential address.
Endoparasites were detected in 25% of samples. Eggs of Toxocara cati were found in 21% of samples, followed by taeniid eggs (4%), oocysts of Cystoisospora felis/C. rivolta and capillarid eggs (both 1%). One cat tested positive for Toxoplasma gondii-like oocysts. Larvae of Aelurostrongylus abstrusus were detected in one cat, which is the first published observation of this parasite in Sweden.
The occurrence of intestinal parasites is rather high in outdoor cats in Sweden, which could indicate the need for more intensive deworming routines in the population. Clinical practitioners should be aware of the possible occurence of A. abstrusus in Swedish cats when considering potential causes of respiratory problems in cats in the future.
本研究旨在收集瑞典猫体内猫内寄生虫的最新流行病学数据。205只户外猫的粪便样本由其主人采集，并提交给国家兽医研究所进行分析。研究对象包括能够接触户外环境且在过去3个月内无驱虫治疗史的猫。采用离心漂浮技术检测肠道寄生虫，并用贝尔曼幼虫沉淀法检测后圆线虫肺吸虫。通过显微镜检查从形态上鉴定虫卵、幼虫和卵囊。从猫主人那里收集了以下信息：品种、性别、年龄、上次使用的驱虫药物、绦虫节片的观察情况和居住地址。
25%的样本检测到体内寄生虫。21%的样本中发现了猫弓首蛔虫卵，其次是带绦虫卵（4%）、猫等孢球虫/里氏等孢球虫卵囊和毛细线虫卵（均为1%）。一只猫的弓形虫样卵囊检测呈阳性。在一只猫中检测到了隐匿猫圆线虫幼虫，这是该寄生虫在瑞典首次发表的观察结果。
瑞典户外猫肠道寄生虫的发生率相当高，这可能表明需要对该群体加强驱虫程序。临床医生在未来考虑猫呼吸道问题的潜在原因时，应意识到瑞典猫可能感染隐匿猫圆线虫。
