Table 2 Summarises metagenomic investigations of camel species including the host species, sequencing technology used, notable prokaryotic taxa detected and postulated roles in the microbiome for the listed taxa. Unless otherwise indicated Dromedary camels were sampled from hot environments, Bactrian from cold; for a indicated studies where no clear location is given for location animals were sampled from

From: A rather dry subject; investigating the study of arid-associated microbial communities
