ABSTRACT
In recent years, the number of cases of tuberculosis (TB) among immigrants in Spain has increased markedly, and led to this analysis of the recent transmission patterns of TB in the immigrant population in Madrid. The countries from which the highest number of immigrant cases have been reported were Ecuador (21%), Romania (16%), Morocco (12%), Peru (11%) and Bolivia (9%). Fifty-one per cent of the cases were from South America. In a multicentre study (2004-2006), IS6110 restriction fragment length polymorphism and spoligotyping were used to genotype the Mycobacterium tuberculosis isolates from 632 immigrant cases from 47 countries. A total of 183 cases (29%) were grouped into 59 clusters, which are markers of potential transmission events. Most of the clusters (81%) included patients living in different healthcare districts, and 54% of the clusters were multinational. When a sample of 478 autochthonous cases was included, 53% of the clusters involving immigrants also included autochthonous cases. This study revealed marked transmission permeability among nationalities and between the immigrant and the autochthonous populations.

We present a case of bacteremic pneumonia caused by Nocardia otitidiscaviarum in a corticodependent COPD. Blood and sputum cultures on Mycobacterial media were positives and identification was done using 16S rDNA sequencing. In this article we review the most relevant communications about Nocardia spp infection and study the strain susceptibility using E-test.

Presentamos un caso de neumonía bacteremica causada por Nocardiaotitidis caviarum en un paciente con bronconeumopatia crónica obstructiva corticodependiente. Los cultivos de sangre y esputo en medios para micobacterias resultaron positivos y la identificación se realizó mediante la secuenciación de 16S rDNA. En el presente artículo se realiza una revisión de conjunto sobre el agente etiológico y se practica el estudio de susceptibilidad de la cepa mediante la técnica de E-Test
