RESULTS OF BACTERIOLOGICAL TESTS IN THOSE SUFFERING FROM PULMONARY MALICIOUS TUMORS DEPENDING ON THE PRESENCE OF COPD AND TECHNIQUE OF THE SAMPLE COLLECTION FROM THE RESPIRATORY TRACT

Abstract

Goal of the study: to study the bacterial population in the respiratory tract at various levels in those suffering from pulmonary malicious tumors including patients with concurrent chronic obstructive pulmonary disease (COPD).Materials and methods. Bacterial population of the respiratory tract was studied in two groups: Group 1 included 52 lung cancer patients without COPD, Group 2 included 23 lung cancer patients with concurrent COPD.Results. In the lung cancer patients none of the technique of the sample collection from respiratory tract used by itself did not allow identification of the whole spectrum of bacterial population in the respiratory tract. The most comprehensive picture of bacterial population in the respiratory tract could be obtained through integral bacteriological testing of the smear out of pharynx, sputum, bronchial aspirate/washout and samples obtained through «protected» brush biopsy. The study of the bacterial population profile showed that Candida fungi prevail in the upper respiratory tract and the following gram-negative bacteria prevail in the lower respiratory tract: Citrobacter, Serratia, Acinetobacter, Pseudomonas, Escherichia, klebsiella, Enterobacter, Burkholderia. It was found out that the bacterial load in the respiratory tract in the lung cancer patients associated with COPD (115 strains in 23 patients) was significantly higher compared to one of those suffering from lung cancer only (108 strains in 52 patients).
