Magnetic microspheres flow cytometry characterization and evaluation.

<p>Reactivities of representative symptomatic (A) and asymptomatic (B) sera tested to different defined combinations of <i>Li</i>cTXNPx and rk39 antigens. Results are expressed as the percentage of positive microspheres. The levels of IgG antibodies anti-rK39 (C) and anti-<i>Li</i>cTXNPx (D) were measured in sera of symptomatic (S), asymptomatic (AS1), asymptomatic PCR+ (AS2), <i>Leishmania</i>-negative but presenting other clinical conditions (OP) and <i>Leishmania</i> negative healthy dogs from non-endemic areas (N). Results are expressed as the percentage of positive microspheres.
