Diagnóstico microbiológico y vigilancia epidemiológica de la campilobacteriosis en Chile: Situación actual y desafíos futuros

Abstract

Campylobacter spp. is considered as the first etiologic agent of diarrhea in developed countries and the second or third in developing countries. The high incidence of Campylobacter gastroenteritis and its possible post-infection sequelae (reactive arthritis, Miller-Fisher syndrome or Guillain-Barré syndrome) give it great importance from the socioeconomic point of view. However, in most developing countries there is no routine microbial diagnosis of this pathogen. In Chile, campylobacteriosis is notifiable since 1983. However, the lack of routine diagnosis by clinical laboratories has made it difficult to know the true prevalence of this pathogen in both intestinal and extra-intestinal infections. In addition, although campylobacteriosis is a zoonotic disease, the diagnosis of this pathogen is not considered within the Chilean Food Sanitary Regulations. All this results in a lack of knowledge about the epidemiology of Campylobacter spp disease in Chile. Therefore, the objective of this review is to analyze the situation of campylobacteriosis in the last two decades in Chile and to determine the challenges that remain to achieve an effective microbial diagnosis and epidemiologic surveillance.
