Phylogenetic relationships, divergence time estimation, and global biogeographic patterns of calopterygoid damselflies (odonata, zygoptera) inferred from ribosomal DNA sequences.
A molecular phylogeny combined with a geographic analysis produced a well-supported phylogenetic hypothesis that partly confirms the traditional taxonomy and describes distributional patterns and a monophyletic origin of the calopterygoids emerges, revealing the Hetaerinid clade as sister group to the CalopteryGidae sensu strictu.

Molecular definition and the ubiquity of species in the genus Naegleria.
To investigate the variability within species of the genus Naegleria, the ITS1,5.8S and ITS2 rDNA were sequenced of several strains of N. lovaniensis and its Western Australian variants and the proposal of eleven new species is proposed. Expand
Phylogenetic relationships inferred from ribosomal its sequences and biogeographic patterns in representatives of the genus Calopteryx (Insecta: Odonata) of the West Mediterranean and adjacent West
Cretan populations are the only splendens-like taxa in addition to C. caprai that deserve subspecies status, and a monophyletic origin of all West Mediterranean and West European species emerged. Expand
Origin and evolution of the worldwide distributed pathogenic amoeboflagellate Naegleria fowleri.
There is strong indication that the pathogenic N. fowleri evolved from the nonpathogenic Naegleria lovaniensis on the American continent, and there is no evidence of virulence differences between the types of N. Fowleri. Expand
Tetramitus thermacidophilus n. sp., an Amoeboflagellate from Acidic Hot Springs
Thermophilic and acidophilic amoeboflagellate isolated from acidic hot springs in the Caldera Uzon and Pisciarelli Solfatara is described and sequence comparisons confirm that T. thermacidophilus is a novel species within the genus Tetramitus and that both isolate belong to that species. Expand
Successful treatment of Naegleria fowleri meningoencephalitis by using intravenous amphotericin B, fluconazole and rifampicin.
Early treatment of PAM by i.v. administration of amphotericin B and fluconazole, and oral administration of rifampicin can offer some hope of cure for this devastating disease. Expand
Naegleria gruberi metabolism.
The completion of the genome project for Naegleria gruberi provides a unique insight into the metabolic capacities of an organism, for which there is an almost complete lack of experimental data. TheExpand
The soil flagellate Proleptomonas faecicola: cell organisation and phylogeny suggest that the only described free-living trypanosomatid is not a kinetoplastid but has cercomonad affinities.
Phylogenetic analysis based on SSU rRNA gene sequences suggests that the cultured organism identified here as Proleptomonas is unrelated to the Kinetoplastida and has affinities with the Phylum Cercozoa Cavalier-Smith, even though in morphology, life cycle and mode of feeding it bears little resemblance to any member of that diverse grouping.

Evaluation of evolutionary divergence in the genus Naegleria by analysis of ribosomal DNA plasmid restriction patterns.
Ribosomal DNA plasmid restriction maps of 10 strains and rDNA hybridisation patterns of 61 additional strains have been used to assess inter- and intra-specific diversity and phylogenetic relationships in the genus Naegleria and indicate that very little variation exists within the pathogenic species Naeglersia fowleri despite its worldwide distribution.

Isolation and identification of pathogenic Naegleria australiensis (Amoebida, Vahlkampfiidae) from a spa in northern Italy.
The virulence of the isolates for mice corresponded with the cytopathic effect for Vero cells, and the presence of pathogenic N. australiensis in the swimming pools did not correlate with bacterial indicators. Expand
