Introduction:
The aim of this study was to describe the distribution of Streptococcus pneumoniae serotypes in isolates from pleural fluid in the Madrid Autonomous Community between the years 2007-2018.
Methods:
Invasive pneumococcal disease strains isolated during the period 2007-2018 were studied. The frequency of serotypes from pleural fluid was compared with that observed in other samples.
Results:
A total of 6,115 pneumococcal invasive isolates were processed. Of them, 182 (3%) were isolated from pleural fluid. A total of 70.9% of isolates belonged to some of the following 6serotypes: 1, 3, 19A, 8, 7F and 5. The serotypes 3 and 8 increased significantly from 9.6% to 30.8%, and from 5.3% to 20.5%, respectively, over the periods 2007-2010 to 2015-2018.
Conclusions:
Pneumococcal serotypes 3 and 8 are currently significant causes of infection of pleural fluid in our region.

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,...
