Four days after inoculation, calves with clinical BRD were treated subcutaneously with saline or tulathromycin (2.5 mg/kg). Compared with saline, BRD-related withdrawals, peak rectal temperatures, and lung lesion scores were significantly lower for tulathromycin-treated calves (P < .01). Tulathromycin was highly effective in the treatment of BRD due to M. bovis in calves regardless of the minimum inhibitory concentration of the challenge strain (1 or >64 microg/ml) [1]. The lowest concentrations inhibiting the growth of 90% of isolates (MIC90) for tulathromycin were 2 microg/ml for Mannheimia (Pasteurella) haemolytica, 1 microg/ml for Pasteurella multocida (bovine), and 2 microg/ml for P<br><br><br><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">公司介绍：MedChemExpress(MCE)专注于各种抑制剂、激动剂、API及化合物库，总部位于美国新泽西，分别在瑞典和上海设有欧洲区子公司和亚洲区总代理，营销网点遍及全球20多个国家地区。MCE经过多年努力已成为全球生物活性小分子领域的一流供应商， 产品涵盖癌症、神经科学、抗感染、表观遗传学等20个热门研究领域，PI3K、MAPK等近千个细分靶点，超过4000个活性小分子化合物现货，以及GPCR、API、离子通道等超过20种不同类型的化合物库，同时提供从毫克到千克的专业定制合成服务。</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">MCE 对每批产品都进行严格的LCMS和NMR检验，其产品已被全球近万名客户广泛使用并发表大量文章、专利；</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">MCE 定期增加各领域热门抑制剂、激动剂，不断扩增已有化合物库，以满足最新的科研需求；</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">数千种产品在上海有充足备货，24-48小时内送达客户；</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">大量产品提供免费试用装；</span><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">已为全球多个知名企业、院校构建各种定制型化合物库。</span><br><br>产品链接：<a href="http://www.medchemexpress.cn/tulathromycin-a.html">www.medchemexpress.cn/tulathromycin-a.html</a><br><br></span><img style="width: 600.0px;height: 310.0px;" src="http://img.dxycdn.com/trademd/upload/userfiles/image/2014/08/A1408605159png_small.jpg" alt="">
