We were lucky enough to have a paper accepted for publication in the ISME Journal (Nature Publishing Group) in which we call for data on the "human intestinal eukaryotome".
In the paper, we start out:
"Recent developments in Next Generation Sequencing (NGS) technologies have allowed culture-independent and deep molecular analysis of the microbial diversity in faecal samples, and have provided new insights into the bacterial composition of the distal gut microbiota. Studies of the microbiome in different patient groups using metagenomics or 16S rRNA gene sequencing are increasing our knowledge of how the microbiota influences health and disease. The majority of recent advances in our understanding of human microbiota structure and dynamic changes in disease were made through phylogenetic interrogation of small subunit (SSU) rRNA (Paliy and Agans 2012). However, until recently such studies have generally failed to include data on common eukaryotic, endobiotic organisms such as single-celled parasites and yeasts ('micro-eukaryotes'). This deficiency may strongly bias the interpretation of results and ignoring an entire kingdom of organisms is a major limitation of human microbiome studies."
We address shortcomings of state-of-the-art methodologies used to explore micro-eukaryotic communities and suggest directions for future research.

Along these lines, there has a publication out just now in PLoS One on "Simultaneous amplicon sequencing to explore co-occurrence patterns of bacterial, archaeal and eukaryotic microorganisms in rumen microbial communities, which can be accessed for free here.
