|May 21, 1982
Resumen
Un hospital experimentó infecciones estreptocócicas (GAS) del grupo A, incluidas las muertes, relacionadas con una enfermera. Las intervenciones detuvieron con éxito la transmisión de GAS y evitaron nuevas infecciones de heridas quirúrgicas.
Área de la Ciencia:
- Enfermedades infecciosas Enfermedades infecciosas.
- Epidemiología de los hospitales.
- Microbiología Microbiología.
Sus antecedentes:
- Las infecciones estreptocócicas del grupo A (GAS) representan un riesgo significativo en entornos postoperatorios.
- La identificación de las fuentes de infecciones adquiridas en el hospital es crucial para la seguridad del paciente.
Objetivo del estudio:
- Para investigar un brote de infecciones por estreptococos del grupo A (GAS) en heridas postoperatorias.
- Para identificar la fuente y la dinámica de transmisión de GAS en un hospital comunitario.
Principales métodos:
- Revisión retrospectiva del caso de diez pacientes con infecciones postoperatorias de la herida por GAS.
- Cultivo microbiológico y serotipo de aislamientos de GAS de pacientes y personal hospitalario.
- Análisis de las exposiciones de los pacientes y los factores quirúrgicos.
Principales resultados:
- Diez casos de infecciones de heridas postoperatorias por GAS ocurrieron en cuatro meses, con dos casos de bacteriemia y una muerte.
- Las infecciones se asociaron con la exposición a una enfermera circulante específica y la duración prolongada de la cirugía.
- La enfermera fue identificada como la fuente de GAS (serotipos M-4, T-4 inicialmente, más tarde M-nontypeable, T-12).
- Los antibióticos profilácticos reducen el riesgo de infección.
Conclusiones:
- Un solo trabajador de la salud puede ser una fuente significativa de transmisión de GAS en un entorno hospitalario.
- Las medidas de control efectivas, incluida la descolonización y reasignación del personal, son vitales para prevenir brotes recurrentes de GAS.
- La rápida identificación y el manejo del personal infectado o colonizado son esenciales para el control de infecciones hospitalarias.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:26Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
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...
01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
01:18Trichomoniasis
Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
