To succeed, many cells must alternate between life-styles that permit rapid growth in the
presence of abundant nutrients and ones that enhance survival in the absence of those …

Lateral gene transfer–the transfer of genetic material between species–has been
acknowledged as a major mechanism in prokaryotic genome evolution for some time …

Giardia intestinalis is a major cause of diarrheal disease worldwide and two major Giardia
genotypes, assemblages A and B, infect humans. The genome of assemblage A parasite …

The adzuki bean beetle, Callosobruchus chinensis, is triple-infected with distinct lineages of
Wolbachia endosymbiont, wBruCon, wBruOri, and wBruAus, which were identified by their …

Intracellular pathogens exploit host cell functions to create a replication niche inside
eukaryotic cells. The causative agent of Legionnaires' disease, the γ-proteobacterium …

The phylogenetic relationships of amoebae are poorly resolved. To address this difficult
question, we have sequenced 1,280 expressed sequence tags from Mastigamoeba …

Background Blastocystis is a highly prevalent anaerobic eukaryotic parasite of humans and
animals that is associated with various gastrointestinal and extraintestinal disorders …

The intestinal parasite Entamoeba histolytica is one of the first protists for which a draft
genome sequence has been published. Although the genome is still incomplete, it is …

Many anaerobic microbial parasites possess highly modified mitochondria known as
mitochondrion-related organelles (MROs). The best-studied of these are the …

Background: Lateral gene transfer (LGT) is an important evolutionary mechanism among
prokaryotes. The situation in eukaryotes is less clear; the human genome sequence failed to …
