Unlike the Plasmodium codon bias (which is heavily skewed towards A/T
richness), Toxoplasma codon usage is quite 'normal'.  As an aside, it
appears that other proteins which do not correspond to the Plasmodium
codon usage (such as Toxoplasma proteins) are nevertheless expressed
(and functional) in Plasmodium. -- DSR
