Dogs in rural areas and hunting dogs in particular, are at higher risk of intestinal helminth infections compared with family dogs. Thus, certain management practices including faecal/coprological analysis, implementing regular deworming protocols, post-treatment evaluations and high-quality hygiene are required in hunting dogs to maintain their health and activity. The aim of this study was to evaluate the efficacy of Drontal Tasty (Vetoquinol S.A.) for the treatment of gastrointestinal helminths in naturally infected hunting dogs in Italy during the hunting and non-hunting season.
Hunting dogs (n = 387) faecal samples were collected from Campania and Basilicata regions, and study was divided into two phases: hunting (P1) and non-hunting (P2) periods. Each sample was screened using Mini-FLOTAC technique with ZnSO as flotation medium (SG: 1.350). The dogs (n = 142) were enrolled on the basis of pre-screening faecal egg counts at day 0 of P1. Dogs exhibiting ≥ 50 EPG species were treated on day 0 of P1 and sampled on day 0, 7 and 14 for faecal analysis. Dogs enrolled in P1 were again controlled in P2 (n = 128) regardless of EPG following the same scheme of P1. The primary criterion for treatment efficacy was the reduction of faecal egg count after D7 and D14 in both P1 and P2.
The anthelmintic efficacy of Drontal Tasty against Toxocara canis was 99.7% and 100% at day 14 in P1 and P2, respectively; for Toxascaris leonina 100% at day 14 in P1, for Ancylostomatidae 100% at day 14 in both P1 and P2; for Trichuris vulpis 88.6% and 99.8% at day 14 in P1 and P2, respectively. For Dipylidium caninum and Taeniidae no positive dogs were detected at day 14 in P1. Although drug is off label for the control of Capillaria spp. the Faecal Egg Count Reduction ranging from 42.1% to 84.5% in P1 and P2, respectively.
Drontal Tasty was well-tolerated and safe against major nematodes and cestodes in hunting dogs. It is the optimum choice to treat helminth infection in hunting dogs under field condition.
与家养宠物狗相比，农村地区的狗，尤其是猎犬，感染肠道蠕虫的风险更高。因此，为了保持猎犬的健康和活动能力，需要采取一些管理措施，包括粪便/粪便学分析、实施定期驱虫方案、治疗后评估以及高质量的卫生措施。本研究的目的是评估法国威隆公司生产的美味多（Drontal Tasty）在意大利狩猎季节和非狩猎季节对自然感染的猎犬胃肠道蠕虫的治疗效果。
从坎帕尼亚和巴西利卡塔地区收集了387只猎犬的粪便样本，研究分为两个阶段：狩猎期（P1）和非狩猎期（P2）。每个样本使用以硫酸锌为浮选介质（比重：1.350）的Mini-FLOTAC技术进行筛查。根据P1第0天的粪便虫卵预筛查计数，选取了142只狗。粪便虫卵计数≥50个/克的狗在P1第0天接受治疗，并在第0、7和14天采集粪便样本进行分析。P1期入选的狗在P2期（n = 128）再次按照P1期的相同方案进行检查，无论其粪便虫卵计数情况如何。治疗效果的主要标准是P1和P2期第7天和第14天后粪便虫卵计数的减少情况。
美味多对犬弓首蛔虫的驱虫效果在P1期第14天为99.7%，在P2期第14天为100%；对狮弓蛔虫在P1期第14天为100%，对钩口科线虫在P1和P2期第14天均为100%；对狐毛首线虫在P1期第14天为88.6%，在P2期第14天为99.8%。对于犬复孔绦虫和带科绦虫，在P1期第14天未检测到阳性犬。尽管该药物未被批准用于控制毛细线虫属感染，但在P1和P2期粪便虫卵计数减少率分别为42.1%至84.5%。
美味多在猎犬中对主要线虫和绦虫耐受性良好且安全。它是野外条件下治疗猎犬蠕虫感染的最佳选择。
