The pharynx and its upper part, the nasopharynx, is an anatomical area in which a huge variety of microorganisms are detected, most of which are part of the normal microflora of the VDP. Green and non-hemolytic streptococci, alpha-hemolytic streptococci, S. epidermidis, Moraxella spp., Neisseria ssp., H. influenzae, Bacteroides, Fusobacterium, diphtheroids and viruses are most often found here. In 80% of people, the presence of H. influenzae in this area is a frequent occurrence. Staphylococcus aureus, Albicans, mycoplasma, and nonencapsulated strains of S. pneumonia are more isolated.
Pharyngitis is one of the most common infections of the respiratory system and is an inflammation of the pharynx and lymphoid tissue of its posterior and lateral walls. Its etiology is associated with bacterial, viral or fungal infection, as well as with non-infectious factors such as smoking, toxic damage. Most cases of pharyngitis are associated with viral infections such as colds or flu. Coxsackie type A viruses can cause severe ulcerative pharyngitis in children (herpangina), and adenovirus and herpes simplex viruses, although less common, can also cause severe pharyngitis. The disease is common in Epstein-Barr viral and cytomegalovirus infections.
The most common bacterial agents of acute pharyngitis and tonsillitis are beta-hemolytic streptococci of group A or Streptococcus pyogenes (pyogenic streptococci). - hemolytic streptococci most often enter the nasopharynx by airborne droplets from a sick or infected carrier, after a viral infection or with suppressed immunity. These streptococci most often cause pharyngitis in children and in adults with weakened immune systems. Pyogenic streptococci, in addition to acute pharyngitis and tonsillitis, often cause local complications such as peritonsillar and parapharyngeal abscesses, otitis media and sinusitis, as well as systemic ones such as rheumatism, rheumocariditis, streptococcal glomerulonephritis. S. pyogenes causes childhood scarlet fever, in which the released bacterial erythrogenic toxin damages the walls of capillaries and causes the appearance of a typical rash, leading to peeling of the affected skin areas. Corynebacterium diphtheriae provokes throat diphtheria in unvaccinated people with characteristic tonic and pharyngeal adhesion. Oral spirochetes - Treponema vincenti and Fusobacterium nucleatum are etiological agents of Plaut-Vincent's angina.
