Phylogenetics and sequence analysis--some problems for the unwary.

, 2003
DNA sequence comparisons can provide deep insight into phylogenetic relationships, but can also present problems for the unwary. Alignment comparisons are not always as straightforward as they might seem, and comparative models applied to deduce ...

Trypanosoma evansi and Surra: A review and perspectives on transmission, epidemiology and control, impact, and zoonotic aspects [PDF]

, 2013
This paper reviews the transmission modes of Trypanosoma evansi. Its worldwide distribution is attributed to mechanical transmission. While the role of tabanids is clear, we raise questions on the relative role of Haematobia sp.

Invasive plants as catalysts for the spread of human parasites

NeoBiota, 2011
As serious as are the consequences of invasive species that directly cause human afflictions through their production of lethal protease inhibitors (Bryonia alba), allergens (Parthenium hysterophorus) or furanocoumarins (Hercaleum mantegazzianum), other ...

Phylogenetic multi-locus codon models and molecular clocks reveal the monophyly of haematophagous reduviid bugs and their evolution at the formation of South America.

, 2010
We previously constructed a single molecular clock to date insect evolution that remains a cornerstone within entomological dating. The insect clock predicts that triatomine bugs, the vectors of South American trypanosomiasis, originated with the ...
