Abstract:
We carried out the bacteriological examination of sputum and bronchoscopy specimens from 31 cases with pneumonia due to C. psittaci. The results obtained were as follows: 1. The positive culture of sputum and bronchoscopy specimens were 38.7% (12/31). 2. The organisms detected from them were 13 strains of gram-negative bacilli, 2 of gram-positive cocci and one gram-positive bacillus. 3. Significant differences were observed in the white blood cell count between the cases of positive culture and those of normal upper respiratory tract flora (p less than 0.05). From the results we conclude that it would be better that we add the proper antimicrobial drugs to chlamydial antibiotics in the treatment of patients with leukocytosis.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
