Phylogenetic analysis has changed greatly in the past decade, including the more
widespread appreciation of the idea that evolutionary histories are not always tree-like, and …

The study of genomic organization and regulatory elements of rRNA genes in metazoan
paradigmatic organisms has led to the most accepted model of rRNA gene organization in …

Canine piroplasmosis is an emerging disease worldwide, with multiple species of piroplasm
now recognised to infect dogs. A nested polymerase chain reaction–restriction fragment …

The cytoplasmic ribosomal RNA (rRNA) genes of the Apicomplexan protozoan parasite
Cryptosporidium parvum have been analyzed with respect to size, copy number …

Comparative modeling of secondary structure is a proven approach to predicting higher
order structural elements in homologous RNA molecules. Here we present the results of a …

The objective of this study was to confirm the presence of seven species of Eimeria involved
in chicken coccidiosis in Australia by comparing internal transcribed spacer 1 (ITS-1) …

Microsporidia are eukaryotic parasites lacking mitochondria, the ribosomes of which present
prokaryote-like features. In order to better understand the structural evolution of rRNA …

As a continuation of our studies on molecular epizootiology of piroplasmosis in Spain and
other countries, we present in this contribution the finding of new hosts for some piroplasms …

Partial mitochondrial (mt) cytochrome c oxidase subunit I (COI) and near-complete nuclear
(nu) 18S rDNA sequences were obtained from various eimeriid coccidia infecting …

Hemogregarines, apicomplexan intracellular blood parasites, are cosmopolitan in
distribution and infect a broad range of vertebrate and invertebrate hosts. Molecular …
