Comparative consumption of amino acids from media and their intensities in parasite samples.

<p>Ratios of amino acids and some derivatives in spent media in comparison with complete medium (A) and between extracts of three <i>Leishmania</i> species (C). The ratios of amino acid intensity for complete medium (Medium) to spent medium from each <i>Leishmania</i> are presented as log₂. Only amino acids and their derivatives which differ from the medium by > log₂1 for at least one species (2A) or between species by > log₂1 (2C) are included. Key: black bar, Medium/<i>L</i>.<i>mexicana</i>; white bar, Medium/<i>L</i>. <i>donovani</i>; grey bar, Medium/<i>L</i>. <i>major</i>. For extracts, intensity ratios between each pair of <i>Leishmania</i> species are expressed as log_2. Key: white bar, <i>L</i>.<i>major</i>/<i>Lmexicana;</i> black bars, <i>L</i>. <i>major</i>/<i>L</i>. <i>donovani</i>; grey bars, <i>L</i>.<i>mexicani</i>/<i>L</i>.<i>donovani</i>. The amounts of amino acids consumed from the medium are also detailed for the three species (B).
