Abstract
Stachybotryschartarum in one of fungi that cause respiratory system infection to human and animals therefore this study it done to evaluation histological changes in some respiratory organs such as nose and lung induced by this fungus suspension . Detection of Stachybotryschartarum fungus confirmed by cultured samples which collected from baths floor on potato dextrose agar in room temperature for seven days. Then the suspension of positive samples of this fungus diluted by phosphate buffer saline and counted the spores by using hemocytometer before used experimentally in lab animals (Balb/C mice) to study histological changes in respiratory system . Twelve mice used in this study divided into two groups. first group consist of six mice induced with 0.5 ml from one positive sample of fungus suspension contain 2×104 spore/mm3 (for month : one dose daily) according to count of hemocytometer to evaluate some histopathological changes in nose and lung .Second group induced with 0.5 ml from phosphate buffer saline only. The results revealed that the nose of mice injected with 0.5 ml contain 2×104 spore/mm3 from Stachybotryschartarum fungus suspension causefocal superficial necrosis of the respiratory epithelial cells with acute inflammatory cells and infiltration of the mucosa while the lung of group mice treated with same concentration of fungus has interstitial pneumonia with thickening of inter alveolar space due to infiltration and chronic inflammatory cells especially mononuclear cell.
