In this study, histopathology of local pulmonary response following intranasal inoculation of different doses of Aspergillus fumigatus conidia in laboratory rats was evaluated. Development of response was evaluated on days seven and twenty one, following conidia inoculation by cell infiltration and by presence of A. fumigatus conidia in homogenates of lung tissue. Total and differential peripheral blood leukocyte counts and state of leukocyte adhesion/aggregation were monitored to estimate the presence of systemic response in infected individuals. Mycological examination revealed the presence of conidia in lung tissue homogenates of infected animals, with high number of non-germinating spores on day twenty one, following the inoculation of lower conidia dose. Histopathological examination revealed the presence of lymphocytes perivascularly and in vascular lumen in the lungs. Presented data demonstrate pulmonary immune response following A. fumigatus conidia administration.
