El brote de gastroenteritis por campylobacter transmitido por el agua
Lancet (London, England)
|February 5, 1983
Resumen
Un internado experimentó un brote de gastroenteritis de 8 semanas. Campylobacter jejuni en el suministro de agua, probablemente de las heces de aves o murciélagos, se relacionó con la enfermedad generalizada en los alumnos y el personal.
Área de la Ciencia:
- Microbiología Microbiología.
- Epidemiología La epidemiología.
- Salud Ambiental Salud del medio ambiente.
Sus antecedentes:
- Los brotes de gastroenteritis pueden interrumpir significativamente las instituciones educativas.
- Las especies de Campylobacter son una causa común de gastroenteritis bacteriana en todo el mundo.
- La transmisión por vía acuática es una vía reconocida para los brotes de enfermedades infecciosas.
Objetivo del estudio:
- Para investigar la causa de un brote de gastroenteritis en un internado.
- Para identificar la fuente y la ruta de transmisión del patógeno.
- Para determinar la asociación entre el consumo de agua y la enfermedad.
Principales métodos:
- Investigación epidemiológica, incluyendo hallazgos de casos y entrevistas.
- Análisis microbiológico de muestras clínicas (alumnos y personal).
- Muestreo y análisis de agua del tanque de agua fría de la escuela.
Principales resultados:
- La gastroenteritis afectó a 234 alumnos y 23 miembros del personal durante 8 semanas.
- Campylobacter spp. también. fueron aislados de las personas afectadas y del suministro de agua.
- Un serotipo específico de Campylobacter jejuni, encontrado en el agua, fue más frecuente en los casos humanos, mostrando una asociación significativa con la enfermedad.
Conclusiones:
- El tanque de almacenamiento de agua fría fue identificado como la probable fuente del brote.
- La contaminación del suministro de agua, posiblemente por heces de aves o murciélagos, condujo al brote de Campylobacter.
- Esto pone de relieve la importancia del monitoreo de la calidad del agua en entornos institucionales.

01:30Reservoir of Infection
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
01:23Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
