Phylogenomic Analysis Reveals Separate Lineages With Continental Segregation.

is a leading cause of waterborne outbreaks globally, and and are the principal cause of human cryptosporidiosis on the planet. Thanks to the advances in Next-Generation Sequencing (NGS) sequencing and bioinformatic software development, more than 100 genomes have been generated in the last decade using a metagenomic-like strategy. This procedure involves the parasite oocyst enrichment from stool samples of infected individuals, NGS sequencing, metagenomic assembly, parasite genome computational filtering, and comparative genomic analysis.

Comparative genomic analysis of the principal species that infect humans.

parasites are ubiquitous and can infect a broad range of vertebrates and are considered the most frequent protozoa associated with waterborne parasitic outbreaks. The intestine is the target of three of the species most frequently found in humans: , , and. .

Plastome reduction and gene content in New World Pilostyles (Apodanthaceae) unveils high similarities to African and Australian congeners.

Holoparasitism has led to extreme plastome reduction. Plastomes in the legume holoparasite Pilostyles (Apodanthaceae) are the most reduced in both size and gene content known so far in Embryophytes. Here, we found that the Pilostyles boyacensis plastome, the only American species sequenced so far, is reduced to seven functional genes, accD, rpl2, rrn16 (=16S), rrn23 (=23S), rps3, rps12 and a putative oxidoreductase (PbOx).
