Abstract

Indian Leishmania donovani isolates (n = 19) from regional zones representing various levels of antimony resistance displayed significantly (P < 0.01) correlated results with respect to in vitro susceptibility to the antileishmanial drugs sodium antimony gluconate, amphotericin B, and Miltefosine, raising the possibility of cross-resistance mechanisms operating in the field isolates. The results of gene expression analysis of LdMT and LdRos3 were suggestive of alternate mechanisms of Miltefosine susceptibility in the isolates.

摘要

来自代表不同锑抗性水平的区域的19株印度杜氏利什曼原虫分离株,在体外对抗利什曼原虫药物葡萄糖酸锑钠、两性霉素B和米替福新的敏感性方面显示出显著(P < 0.01)相关的结果,这增加了野外分离株中存在交叉抗性机制的可能性。LdMT和LdRos3的基因表达分析结果提示了分离株中米替福新敏感性的替代机制。
