We describe the identification of the leopard cat (Prionailurus bengalensis), jungle cat (Felis chaus) fishing cat (Prionailurus viverrinusis), wild cat (Felis silvestris) and caracal (Caracal caracal) using combined approach of morphological and molecular based analysis. Three mitochondrial genes [12S rRNA, 16S rRNA and cytochrome b (Cyt b)] and hair characteristics (cuticle and medulla patterns) were analysed and variation was observed among few selected wild felids. We did not find conclusive morphological difference among these examined felids. We observed maximum variation in Cyt b in comparison to12S rRNA and 16S rRNA genes. Therefore, despite poor hair morphological difference, forensically informative nucleotide sequencing (FINS) exhibited unambiguous variation among the examined felids. We suggest the use of FINS for differentiating biological samples of closely related wild felids to avoid any false identification of species in illicit trade. Furthermore, the data generated from the present work would help in strengthening the DNA database of Indian small cats.
我们描述了采用形态学和分子分析相结合的方法对豹猫(豹猫属孟加拉亚种)、丛林猫(沙猫)、渔猫(渔猫属渔猫种)、野猫(欧林猫)和狞猫(狞猫属狞猫种)的鉴定过程。分析了三个线粒体基因[12S核糖体RNA、16S核糖体RNA和细胞色素b(Cyt b)]以及毛发特征(角质层和髓质模式),并在少数选定的野生猫科动物中观察到了变异。我们在这些经检测的猫科动物中未发现确凿的形态差异。与12S核糖体RNA和16S核糖体RNA基因相比,我们观察到细胞色素b的变异最大。因此,尽管毛发形态差异不大,但法医信息核苷酸测序(FINS)在经检测的猫科动物中显示出明确的变异。我们建议使用FINS来区分亲缘关系密切的野生猫科动物的生物样本,以避免在非法贸易中对物种进行任何错误鉴定。此外,本研究产生的数据将有助于加强印度小型猫科动物的DNA数据库。
