Abstract

It is important to continuously monitor the prevalence of parasitic infections in client-owned dogs. However, very limited information is available for the Pacific Northwest (PNW) region of the United States (US). Our main study objective was to determine the prevalence of parasitism observed in the feces of client-owned dogs in the PNW, US. Additionally, the prevalence of parasitic infections was statistically compared by sex, age, and seasonality. Results of all the fecal examinations with various methodologies performed at Zoetis Reference Laboratories in Mukilteo, Washington, from February 1, 2021 to December 31, 2023, were examined. A total of 82,603 fecal samples tested were included in this study. Most samples (88.47 %; 73,076/82,603) did not contain any parasites or eggs. A single parasite was identified in 8322 (10.07 %) samples, whereas multiple parasites were seen in 1205 (1.46 %) samples. The most commonly diagnosed parasite was Giardia (6.77 %, 5596/82,603), followed by Cystoisospora (1.86 %, 1535/82,603), Toxocara canis (1.85 %, 1526/82,603), Ancylostoma (0.82 %, 679/82,603), Cryptosporidium (0.76 %, 629/82,603), Trichuris vulpis (0.33 %, 271/82,603), Toxascaris leonina (0.22 %, 178/82,603), taeniids (0.15 %, 122/82,603), Sarcocystis (0.12 %, 84/82,603), Nanophyetus salmincola (0.09 %, 74/82,603), Dipylidium caninum (0.07 %, 60/82,603), Neospora-like coccidia (0.06 %, 47/82,603), Capillaria (0.03 %, 27/82,603), Demodex (0.02 %; 17/82,603), Baylisascaris (0.01 %, 9/82,603), Spirometra (0.01 %, 7/82,603), and Otodectes cynotis (0.01 %; 5/82,603). Additionally, Strongyloides stercoralis larvae were found in four cases, and Alaria eggs, Cheyletiella mites, and possible Oslerus/Filaroides larvae were identified in one case. This study indicates the importance of routine fecal examinations and application of broad-spectrum anthelmintics to dogs in the PNW region.

2021-2023年美国太平洋西北地区通过粪便检查确定客户犬的寄生虫患病率

重要的是持续监测客户养狗中寄生虫感染的流行情况。然而，关于美国太平洋西北地区（PNW）的信息非常有限。我们的主要研究目的是确定在PNW，美国客户拥有的狗的粪便中观察到的寄生虫的患病率。此外，寄生虫感染的流行率按性别、年龄和季节性进行统计比较。对2021年2月1日至2023年12月31日在华盛顿州穆基泰奥Zoetis参考实验室采用各种方法进行的所有粪便检查结果进行检查。本研究共检测了82603份粪便样本。大部分样本（88.47%）；73,076/82,603)不含任何寄生虫或卵。8322份（10.07%）标本中检出单一寄生虫，1205份（1.46%）标本中检出多种寄生虫。最常见的寄生虫是贾第鞭毛虫（6.77%,5596/82,603），其次是囊异孢子虫（1.86%,1535/82,603）、犬弓形虫（1.85%,1526/82,603）、钩虫（0.82%,679/82,603）、隐孢子虫（0.76%,629/82,603）、狐毛虫（0.33%,271/82,603）、狮子弓形虫（0.22%,171 /82,603）、带绦虫（0.15%,122/82,603）、肉囊虫（0.12%,84/82,603）、沙蚤（0.09%,74/82,603）、犬双螺旋虫（0.07%,60/82,603）、新孢子虫样球虫（0.06%,82,603）。47/82,603)，毛细线虫（0.03%,27/82,603），蠕形螨(0.02%；（17/82,603）， Baylisascaris (0.01%, 9/82,603), Spirometra（0.01%, 7/82,603）和Otodectes cynotis (0.01%；5/82,603)。4例检出粪类圆线虫幼虫，1例检出阿拉氏卵、车氏螨和可能的奥氏/丝状线虫幼虫。本研究提示PNW地区犬常规粪便检查和广谱驱虫药应用的重要性。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
