    Aspergillosis is an infection caused by Aspergillus, ubiquitous mold found in indoor and outdoor air. In patients with immune suppression and underlying lung diseases Aspergillus spores are able to cause various pathologic conditions. Annually 200000 new cases of invasive aspergillosis (IA) are registered. Mortality due to IA in chronic obstructive pulmonary diseases (COPD) patients varies within 72-95%. 3 million people suffer from different forms of chronic pulmonary aspergillosis (CPA). The aim of the investigation was to determine the incidence of Aspergillus species and their diagnostic significance in clinical samples. Specimens of 1170 patients were investigated for the presence of Aspergillus spp. for period from august 2017 to august 2018. The collected specimens were inoculated onto Sabouraud dextrose agar with chloramphenicol and incubated at 37 ?? temperature for 10 days. In case of growth of mold colonies, further identification was performed based on macroscopic and microscopic features. Growth of Aspergillus spp. colonies were detected in 22 patients (1.88%). 16 of them were males, 6 – females. 7 patients had COPD, 7- bronchial asthma (BA), 4 – pulmonary tuberculosis (PT), 1 – acute respiratory insufficiency, 1 – bronchiectatic disease, 1 – exudative pleurisy and 1 – acute leucosis. Four different species were isolated: Aspergillus niger, A. fumigatus, A. flavus, and A. terreus. A. niger commonly was associated with BA, while in patients with COPD and PT prevailed A. fumigatus. We consider that in patients with COPD and PT risk of aspergillosis should be taken into account in order to provide them with appropriate treatment and reduce mortality rates.
