Abstract

In Japan, the three main crane species are the endangered red-crowned crane (Grus japonensis) inhabiting Hokkaido, the northernmost island of Japan; the vulnerable hooded crane (G. monacha); and the vulnerable white-naped crane (G. vipio). Both the hooded and white-naped cranes migrate in winter to Izumi in Kyushu, the southern island of Japan. In this study, we investigated the cranes and their coccidian parasites, through a targeted molecular approach using faecal DNA to develop a non-invasive method for infectious disease research. To determine the origin of non-invasively collected faecal samples, host species were identified by sequencing a region of approximately 470 bp of the mitochondrial 16S ribosomal RNA gene in the faecal DNA. Furthermore, to avoid sample redundancy, individual determination was performed by fragment analysis using microsatellite and sex-linked markers. For microsatellite genotyping, previously reported markers and markers isolated in this study were examined, and seven loci for red-crowned cranes, eight for hooded cranes and six for white-naped cranes displayed polymorphisms. A low error rate was demonstrated by comparing microsatellite data generated from faecal DNA samples with that generated from feather DNA samples, indicating a high reliability. Polymerase chain reaction-based capillary electrophoresis (PCR-CE), employing genetic markers in the second internal transcribed spacer (ITS2) of nuclear ribosomal DNA, was employed to detect crane coccidia. The sensitivity of detection of PCR-CE using faecal DNA was inferior to that with traditional microscopy; however, our results suggest that PCR-CE can depict crane coccidia diversity with higher resolution and it is a useful tool to characterize community composition of coccidia in detail.
