DIVERSITY OF BACTERIA AND FUNGI AND PHAGOCYTIC PROPERTIES OF NEUTROPHILS IN SOME RESPIRATORY DISEASES
Respiratory diseases are considered serious diseases that affect all age groups and can lead, in most cases, to death. This study aimed to investigate the bacterial and fungal causes of some respiratory infections and the relationship between the phagocytic activity of polymorphonuclear cells and respiratory tract infection.146 clinical samples of sputum were collected from 50 patients with chronic tuberculosis, and pharyngeal swabs from 96 patients with respiratory infections other than tuberculosis, including chronic bronchitis (22 patients), allergic (66 patients), and asthma (5patients) pneumonia (3 patients). These samples were collected from patients referred to the Specialized National Centre for Chest and Respiratory Diseases in Baghdad for the period between 2018and 2019. It has been found that out of the total 146 patients, the number of infected males is 76 (52.1 %) and 70 females (47.9%). 174 bacterial isolates were isolated and identified, as well as it was noted that the percentage of respiratory infections caused by gram-positive bacteria was higher (66.1%) compared to the respiratory infections caused by gram-negative bacteria (33.9%), As for fungal infections, from 140 isolates showed that the percentage of respiratory infections caused by fungi was the highest (70.9%) compared to respiratory infections caused by yeasts (29%). The current study indicated that respiratory tract infections stimulated the phagocytic activity of polymorphonuclear cells for all age groups. Keywords:
