In many areas of the world, only 30 to 50% of dogs are vaccinated against rabies. On some US Indian Reservations, vaccination rates may be as low as 5 to 20%. In 2003 and 2004, we evaluated the effectiveness of commercially available baits to deliver oral rabies vaccine to feral and free-ranging dogs on the Navajo and Hopi Nations. Dogs were offered one of the following baits containing a plastic packet filled with placebo vaccine: vegetable shortening-based Ontario slim baits (Artemis Technologies, Inc.), fish-meal-crumble coated sachets (Merial, Ltd.), dog food polymer baits (Bait-Tek, Inc.), or fish meal polymer baits (Bait-Tek, Inc.). One bait was offered to each animal and its behaviour toward the bait was recorded. Behaviours included: bait ignored, bait swallowed whole, bait chewed and discarded (sachet intact), bait chewed and discarded (sachet punctured), or bait chewed and consumed (sachet punctured). Bait acceptance ranged from 30.7% to 77.8% with the fish-meal-crumble coated sachets having the highest acceptance rate of the tested baits.
在世界许多地区，只有30%至50%的狗接种了狂犬病疫苗。在美国的一些印第安人保留地，疫苗接种率可能低至5%至20%。在2003年和2004年，我们评估了市售诱饵向纳瓦霍族和霍皮族的野生及散养犬只投喂口服狂犬病疫苗的效果。给犬只提供以下其中一种装有填充了安慰剂疫苗的塑料包的诱饵：以植物起酥油为基础的安大略细条诱饵（阿耳忒弥斯技术公司）、鱼粉碎屑包裹的香囊（梅里亚有限公司）、狗粮聚合物诱饵（诱饵技术公司）或鱼粉聚合物诱饵（诱饵技术公司）。给每只动物提供一种诱饵，并记录其对诱饵的行为。行为包括：忽略诱饵、整个吞下诱饵、咀嚼并丢弃诱饵（香囊完好）、咀嚼并丢弃诱饵（香囊刺破）或咀嚼并吃掉诱饵（香囊刺破）。诱饵接受率在30.7%至77.8%之间，其中鱼粉碎屑包裹的香囊在受试诱饵中接受率最高。
