Resumen
Los Campylobacter termotolerantes(CT) son considerados la causa bacteriana más frecuente de gastroenteritis humana en el mundo. Los CT circulan frecuentemente en aves de corral, siendo éstas la principal fuente de infección para los humanos. El mayor factor de riesgo es la manipulación y el consumo del pollo fresco en el hogar. Asimismo, existen reportes frecuentes de infecciones por CT en aves silvestres. Sin embargo, hasta la actualidad no está claro qué rol cumplen en su epidemiología. Este trabajo revisa el conocimiento científico actual sobre CT en aves silvestres. La mayoría de los estudios de CT en aves silvestres se focalizan en ambientes productivos, principalmente, en establecimientos de pollos de engorde, destacándose que la principal especie hallada es Campylobacter jejuni. En menor medida existen estudios en aves silvestres de zonas urbanas y áreas naturales. La prevalencia de CT en aves silvestres parece estar asociada a la familia taxonómica, gremio ecológico y distribución geográfica de las diversas especies de aves. La literatura existente sugiere que las aves silvestres tienen el potencial de cumplir un rol a considerar en la epidemiología de CT, involucrándose en tres aspectos: 1) actuando como reservorios; 2) transportando CT a diferentes distancias; y 3) siendo compartimento donde se puede generar y mantener resistencia antimicrobiana.
Thermotolerant Campylobacter (TC) are considered the most common bacterial cause of human gastroenteritis in the world. These bacteria circulate frequently in poultry, which are the main source of infection for humans. The main risk factor is the manipulation of fresh chicken meat for preparation of food at home. Nonetheless, wild birds have been frequently reported infected by CT. In spite of that, to date it is not clear which role they have in the epidemiology of this zoonotic agent. This work reviews the current scientific knowledge on CT in wild birds. Most studies in those animals have been conducted in productive systems, mainly broiler farms, where the main species reported is Campylobacter jejuni. To a lesser extent, there are studies in urban areas and natural settings. The prevalence of CT in wild birds appears to be associated to the taxonomic family, the ecological guild, and geographic distribution of the diverse avian species. The exant literature suggests that wild birds may have the potential of playing a considerable role in CT epidemiology, getting involved in the following, 1) being alternative reservoirs; 2) transporting CT to varying distances; and 3) being compartments in which CT antimicrobial resistance can be maintained and generated.
