La flora aeróbica y anaeróbica de la superficie frente a la de las amígdalas del núcleo en la amigdalitis recurrente
JAMA
|October 10, 1980
Resumen
Los cultivos de amígdalas superficiales pueden pasar por alto las bacterias anaerobias, incluidos los patógenos productores de beta-lactamasa, cruciales para comprender la amigdalitis recurrente. Los cultivos centrales son esenciales para una evaluación microbiana integral.
Área de la Ciencia:
- Microbiología Microbiología.
- La otorrinolaringología otorrinolaringología.
- Enfermedades infecciosas Enfermedades infecciosas.
Sus antecedentes:
- La amigdalitis recurrente implica complejas comunidades microbianas dentro de los tejidos de las amígdalas.
- Comprender el espectro completo de microorganismos, incluidos los anaeróbicos, es vital para un tratamiento eficaz.
Objetivo del estudio:
- Para comparar la flora microbiana aislada de la superficie frente a las muestras de amígdalas del núcleo.
- Evaluar la prevalencia de la producción de beta-lactamasa en los aislados de amigdalitis recurrente.
Principales métodos:
- Se cultivaron muestras de superficie y núcleo de amígdalas de 23 niños con amigdalitis recurrente para detectar bacterias aeróbicas y anaeróbicas.
- Se identificaron aislados y se evaluó la producción de beta-lactamasa.
Principales resultados:
- La flora aeróbica y anaeróbica mixta prevaleció en todos los pacientes.
- Las bacterias anaerobias como Bacteroides sp. y Fusobacterium nucleatum fueron comunes.
- La producción de beta-lactamasa se observó en el 83% de los pacientes.
- Las bacterias anaerobias fueron más frecuentemente aisladas de los especímenes del núcleo (33% frente al 10% de los aeróbios).
Conclusiones:
- Existen discrepancias significativas entre los cultivos de amígdalas superficiales y centrales para las bacterias anaerobias.
- Los cultivos superficiales pueden no reflejar con precisión los patógenos microbianos centrales en la amigdalitis recurrente.
- Los cultivos de núcleo son necesarios para la detección de organismos productores de beta-lactamasa.

01:30Acute Pharyngitis
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:30Tonsillitis I: Introduction
Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
01:29Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
