ABSTRACT:
INTRODUCTION
Pneumonia is an inflammation of the lung structures, primarily the alveoli and bronchioles, caused by a variety of pathogens, with Streptococcus pneumoniae being one of the most prevalent. This Gram-positive bacterium is the main cause of pneumococcal disease, particularly affecting children and the elderly. In addition to S. pneumoniae, other common pathogens include Haemophilus influenzae, Staphylococcus aureus, and Gram-negative bacilli. S. pneumoniae is a diplococcus with a polysaccharide capsule, which plays a crucial role in the microorganism' s virulence, as it inhibits the action of phagocytes, hindering the host' s immune response.
