Background

Giardia duodenalis is a widespread protozoan parasite affecting humans and many species of animals, including dogs and cats. Due to its zoonotic potential, it is important to know the frequency of this parasite in companion animals. The aim of this study was to determine current epidemiological status of G. duodenalis in household dogs and cats.

Methods

In this study, 293 fecal samples from pet dogs and cats were collected from January 2017 to July 2019 and tested for G. duodenalis by PCR (using β-giardin gene). The animals were divided into groups depending on their age, breed and fecal consistency.

Results

The examination allowed for detection of G. duodenalis in 6.0% of canine and 3.9% of feline fecal samples. The highest frequency was revealed in young (under one-year old) dogs. Sequencing confirmed the presence of assemblages C and D in dogs and A and F in cats.

Conclusion

The study showed current frequency of G. duodenalis in dogs and cats and also revealed the occurrence of host-specific assemblages as well as zoonotic assemblage A.

波兰家养犬猫十二指肠贾第鞭毛虫基因型

背景

十二指肠贾第鞭毛虫是一种广泛存在的原生动物寄生虫，影响人类和许多动物，包括狗和猫。由于其人畜共患病的潜力，了解这种寄生虫在伴侣动物中的频率非常重要。本研究的目的是确定家犬和猫中十二指肠球菌的当前流行病学状况。

方法

在这项研究中，从 2017 年 1 月到 2019 年 7 月收集了 293 份宠物狗和猫的粪便样本，并通过 PCR（使用 β-giardin 基因）检测了十二指肠球菌。动物根据它们的年龄、品种和粪便稠度被分成组。

结果

该检查允许在 6.0% 的犬科动物和 3.9% 的猫科动物粪便样本中检测到十二指肠球菌。最高频率出现在年轻（一岁以下）的狗身上。测序证实了在狗中存在组合 C 和 D，在猫中存在组合 A 和 F。

结论

该研究显示了狗和猫中G.duodenalis 的当前频率，还揭示了宿主特异性组合以及人畜共患病组合 A 的发生。
