A newly developed nested PCR assay was applied to murine models of
histoplasmosis. ICR and BALB/c mice were intravenously infected with
Histoplasma capsulatum and sacrificed up to 29 days later.
Samples of blood, spleen, and lung homogenates were cultured and
examined by the PCR assay. In the ICR mouse model, 265 of 319 organ
samples showed concordant results. With 7 samples, the culture was
positive and the PCR assay was negative whereas a positive PCR but a
negative culture were obtained with 47 samples (P < 0.0001 according to McNemar's test). Organ homogenates and blood
samples of either spontaneously cured or treated BALB/c mice were PCR
negative. The nested PCR assay performs excellently in the monitoring
of spontaneously and treatment-cured murine histoplasmosis. It limits
the infection risks of the laboratory staff and might be of diagnostic
value for humans.
