Resumen en inglés The organisms of Rickettsia species are Gram (-) bacteria that cause severe illnesses in humans and are an important health problem in several countries around the world, including Mexico. The presence of different antigens between species and also in different strains of the same specie is an obstacle for vaccine development and serological diagnosis. There are important advances in the knowledge of the rickettsial antigenic structure and the resulting immune response in (mas) infected hosts, including humans. This review covers these topics and provides an overview about the development of vaccines and accessible diagnostic methods for diseases caused by Rickettsia (Rev Méd Chile 2004; 132: 381-7)

Resumen en español En este artículo se presenta la historia de la fiebre tifoidea (FT) en Chile desde su reconocimiento como entidad nosológica hasta su situación actual. De la historia destaca la confusión que hubo en Chile durante muchos años entre esta enfermedad y el tifus exantemático a pesar de que la fiebre tifoidea ya había sido individualizada y caracterizada en la primera mitad del siglo XIX en Europa. Esto se podría explicar porque tenían ciertas manifestaciones clínica (mas) s similares (fiebre alta y delirio) y por ocurrir en condiciones de déficit ambiental. Esta confusión se soluciona recién en 1918 en relación con la gran epidemia de tifus exantemático que permite a los clínicos identificarlo con toda claridad. Una vez distinguida la FT fue posible describir su comportamiento, caracterizado por un alto nivel de endemia, de preferencia en zonas urbanas con alzas estivales y ciclos epidémicos. De la historia contemporánea de la FT resalta la Gran Epidemia de 1976-1985, asociada al brusco deterioro socioeconómico y ambiental, y la igualmente abrupta caída de la enfermedad en 1992, reducción que persiste hasta nuestros días. Este último fenómeno, fue el resultado del carácter cuasi-experimental de las intervenciones de salud pública y educación sanitaria realizadas en 1992 para evitar la epidemia de cólera que estaba extendiéndose en el Perú. Concluimos que, si bien la hipótesis de la contaminación ambiental como el factor clave en la persistencia de la FT estuvo presente desde el reconocimiento de la enfermedad en 1894, sólo se abordó de manera eficaz y tal vez definitiva casi 100 años más tarde Resumen en inglés This article presents the history of typhoid fever in Chile since its definition as a clinical entity until our days. From this history is evident the long lasting confusion with typhus (rickettsial spotted fever) in Chile although the identity and characteristics of typhoid fever had been established in the first half of nineteenth century in Europe. This confusion could be explained because some clinical features are similar in both diseases (high fever and delirium) an (mas) d because of its ocurrence in poor hygienic conditions. This misconception was resolved only during 1918 on occasion of a major typhus outbreak that allowed physicians to clearly diagnose this rickettsial disease. Once typhoid fever was recognized it was possible to describe its epidemiological pattern with high endemic incidence mainly in urban districts, with summer increases and epidemic cycles. In the contemporary history of typhoid fever it is remarkable a huge outbreak during 1976-1985, associated to abrupt socioeconomical and environment crisis, as well as an abrupt diminution of the disease in 1992, with a marked reduction that persists until now. This last phenomenon was the consequence of a cuasi-experimental public health intervention and sanitary education conducted in 1992 to avoid the cholera epidemic that was spreading in Perú, a neighboring country. We conclude that, although the hypothesis of environment contamination as the cornerstone in typhoid persistence was present since the recognition of the disease in 1894, it was faced efficiently only and perhaps in a definitely manner only almost 100 years later
